近来，移动终端的多媒体功能已得到改进。例如，相机基本内置在移动终端中并且相机的分辨率逐渐增加到现有数码相机的水平。然而，移动终端的前置相机限制了屏幕的设计，从而使得难以设计屏幕。为了减小相机占据的空间，在移动终端中已采取了包括切口(notch)或打孔(punch hole)之类的屏幕设计，但是因为屏幕尺寸仍旧由于相机而受到限制，所以难以实现全屏显示(Full-screen display)。Recently, multimedia functions of mobile terminals have been improved. For example, cameras are basically built into mobile terminals and the resolution of cameras is gradually increasing to the level of existing digital cameras. However, the front camera of the mobile terminal limits the design of the screen, thereby making it difficult to design the screen. In order to reduce the space occupied by the camera, screen designs including notch or punch hole have been adopted in mobile terminals, but because the screen size is still limited due to the camera, it is difficult to achieve full-screen display ( Full-screen display).

为了实现全屏显示，已提出这样的方法，即，在显示面板的屏幕中制备设置有低分辨率像素的成像区域，并且将相机和/或各种传感器设置在成像区域中。In order to realize full-screen display, a method has been proposed in which an imaging area provided with low-resolution pixels is prepared in a screen of a display panel, and a camera and/or various sensors are provided in the imaging area.

The camera module may include an image sensor. The pixels of the second display area CA may display an input image by writing pixel data of the input image in a display mode.

相机模块可在成像模式中拍摄外部图像，以输出图片或视频图像数据。相机模块的透镜30可面向第二显示区域CA。外部光通过第二显示区域CA入射到相机模块的透镜30上，并且透镜30可将光会聚到图中省略的图像传感器上。相机模块可在成像模式中拍摄外部图像，以输出图片或视频图像数据。The camera module can capture external images in an imaging mode to output picture or video image data. Thelens 30 of the camera module may face the second display area CA. External light is incident on thelens 30 of the camera module through the second display area CA, and thelens 30 may condense the light onto an image sensor omitted in the drawing. The camera module can capture external images in an imaging mode to output picture or video image data.

为了确保光透射率，由于从第二显示区域CA去除了像素，所以可应用用于补偿第二显示区域CA中的像素的亮度和色坐标的图像质量补偿算法。In order to ensure light transmittance, since pixels are removed from the second display area CA, an image quality compensation algorithm for compensating brightness and color coordinates of pixels in the second display area CA may be applied.

显示面板100可具有沿X轴方向的宽度、沿Y轴方向的长度和沿Z轴方向的厚度。显示面板100可包括设置在基板10上的电路层12、和设置在电路层12上的发光元件层14。可在发光元件层14上设置偏振板18，并且可在偏振板18上设置盖玻璃20。Thedisplay panel 100 may have a width along an X-axis direction, a length along a Y-axis direction, and a thickness along a Z-axis direction. Thedisplay panel 100 may include acircuit layer 12 disposed on thesubstrate 10 , and a light emittingelement layer 14 disposed on thecircuit layer 12 . Apolarizing plate 18 may be provided on the light emittingelement layer 14 , and acover glass 20 may be provided on thepolarizing plate 18 .

电路层12可包括与诸如数据线、栅极线、电源线等之类的线连接的像素电路；与栅极线连接的栅极驱动单元等。Thecircuit layer 12 may include pixel circuits connected to lines such as data lines, gate lines, power lines, etc.; gate driving units connected to gate lines; and the like.

电路层12可包括电路元件，诸如实现为薄膜晶体管(Thin Film Transistor，TFT)的晶体管、电容器等。电路层12的线和电路元件可由多个绝缘层、之间隔着绝缘层彼此分离的两个或更多个金属层、以及包括半导体材料的有源层实现。Thecircuit layer 12 may include circuit elements such as transistors implemented as thin film transistors (Thin Film Transistor, TFT), capacitors, and the like. The lines and circuit elements of thecircuit layer 12 may be realized by a plurality of insulating layers, two or more metal layers separated from each other with an insulating layer therebetween, and an active layer including a semiconductor material.

发光元件层14可包括被像素电路驱动的发光元件。发光元件可实现为OLED。OLED可包括形成在阳极与阴极之间的有机化合物层。The light emittingelement layer 14 may include light emitting elements driven by pixel circuits. The light emitting element can be realized as an OLED. An OLED may include an organic compound layer formed between an anode and a cathode.

有机化合物层可包括空穴注入层(Hole Injection layer，HIL)、空穴传输层(Hole transport layer，HTL)、发光层(Emission layer，EML)、电子传输层(Electrontransport layer，ETL)、和电子注入层(Electron Injection layer，EIL)，但本公开内容不限于此。The organic compound layer may include a hole injection layer (Hole Injection layer, HIL), a hole transport layer (Hole transport layer, HTL), an emission layer (Emission layer, EML), an electron transport layer (Electron transport layer, ETL), and electron Injection layer (Electron Injection layer, EIL), but the present disclosure is not limited thereto.

当电压施加至OLED的阳极和阴极时，穿过空穴传输层HTL的空穴和穿过电子传输层ETL的电子移动到发光层EML以产生激子，因而可从发光层EML发射可见光。When a voltage is applied to the anode and cathode of the OLED, holes passing through the hole transport layer HTL and electrons passing through the electron transport layer ETL move to the emission layer EML to generate excitons, and thus visible light can be emitted from the emission layer EML.

发光元件层14可进一步包括设置在像素上的、选择性地透过红色波长、绿色波长和蓝色波长的光的滤色器阵列。The light emittingelement layer 14 may further include a color filter array disposed on the pixels to selectively transmit light of red wavelength, green wavelength, and blue wavelength.

发光元件层14可被保护膜覆盖，保护膜可被封装层(encapsulation layer)覆盖。保护膜和封装层可具有其中有机膜和无机膜交替堆叠的结构。无机膜可阻挡湿气或氧气的渗透。有机膜可使无机膜的表面平坦化。当有机膜和无机膜堆叠多层时，由于与单层相比，湿气或氧气的移动路径的长度增加，所以可有效阻挡影响发光元件层14的湿气/氧气的渗透。The light emittingelement layer 14 may be covered by a protective film, and the protective film may be covered by an encapsulation layer. The protective film and the encapsulation layer may have a structure in which organic films and inorganic films are alternately stacked. The inorganic membrane blocks the penetration of moisture or oxygen. The organic film can planarize the surface of the inorganic film. When the organic film and the inorganic film are stacked in multiple layers, since the length of the moving path of moisture or oxygen is increased compared with a single layer, permeation of moisture/oxygen affecting the light emittingelement layer 14 can be effectively blocked.

偏振板18可设置在封装层上。偏振板18可提高显示装置的户外可视性。偏振板18可减小光从显示面板100的表面的反射并且阻挡从电路层12的金属反射的光，从而提高像素的亮度。偏振板18可实现为其中线性偏振板和相位延迟膜结合的偏振板、或者圆偏振板。Thepolarizing plate 18 may be disposed on the encapsulation layer. Thepolarizing plate 18 can improve the outdoor visibility of the display device. Thepolarizing plate 18 may reduce the reflection of light from the surface of thedisplay panel 100 and block the light reflected from the metal of thecircuit layer 12, thereby improving the brightness of the pixel. Thepolarizing plate 18 may be implemented as a polarizing plate in which a linear polarizing plate and a phase retardation film are combined, or a circular polarizing plate.

参照图4，第一显示区域DA可包括布置成矩阵形式的多个第一像素组PG1。在多个第一像素组PG1中，两个子像素可使用子像素渲染算法形成一个像素。例如，第一单位像素PIX1可包括R和G1子像素SP1、SP2，第二单位像素PIX2可包括B和G2子像素SP3、SP4。可利用相邻像素之间的各条相应颜色数据的平均值补偿单位像素PIX1和PIX2的每一个中不充分的颜色呈现。然而，本公开内容不必限于此，多个第一像素组PG1可以是包括R子像素、G子像素和B子像素的真实型像素。Referring to FIG. 4 , the first display area DA may include a plurality of first pixel groups PG1 arranged in a matrix form. In the plurality of first pixel groups PG1, two sub-pixels may form one pixel using a sub-pixel rendering algorithm. For example, the first unit pixel PIX1 may include R and G1 sub-pixels SP1, SP2, and the second unit pixel PIX2 may include B and G2 sub-pixels SP3, SP4. Insufficient color representation in each of the unit pixels PIX1 and PIX2 may be compensated for using an average value of respective pieces of corresponding color data between adjacent pixels. However, the present disclosure is not necessarily limited thereto, and the plurality of first pixel groups PG1 may be real-type pixels including R sub-pixels, G sub-pixels, and B sub-pixels.

多个第一像素组PG1的每一个可包括红色发光元件R、第一绿色发光元件G1、蓝色发光元件B和第二绿色发光元件G2。在此，将每个第一像素组PG1中的第一绿色发光元件G1和第二绿色发光元件G2的每一个的中心连接的虚拟线可平行于第一方向。Each of the plurality of first pixel groups PG1 may include a red light emitting element R, a first green light emitting element G1, a blue light emitting element B, and a second green light emitting element G2. Here, a virtual line connecting centers of each of the first green light emitting element G1 and the second green light emitting element G2 in each first pixel group PG1 may be parallel to the first direction.

图5是图解根据本公开内容一个实施方式的第二显示区域的像素和透光区域的视图。FIG. 5 is a view illustrating pixels of a second display area and a light transmission area according to one embodiment of the present disclosure.

参照图5，第二显示区域CA可包括多个第二像素组PG2和多个透光区域TA。多个透光区域TA可设置在多个第二像素组PG2之间。具体地，透光区域TA与第二像素组PG2可沿第一方向和第二方向交替设置。外部光可通过透光区域TA被接收到相机模块的透镜。第二显示区域CA的分辨率可相对于第一显示区域DA的分辨率降低透光区域TA的面积增加的程度。Referring to FIG. 5 , the second display area CA may include a plurality of second pixel groups PG2 and a plurality of light transmitting areas TA. A plurality of light transmitting areas TA may be disposed between the plurality of second pixel groups PG2. Specifically, the light-transmitting area TA and the second pixel group PG2 may be alternately arranged along the first direction and the second direction. External light may be received to the lens of the camera module through the light transmission area TA. The resolution of the second display area CA may be reduced relative to the resolution of the first display area DA by an increase in the area of the light-transmitting area TA.

透光区域TA可包括具有高光透射率而不具有金属的透明介质，使得光可以以最小的光损耗进行入射。透光区域TA可由不包括金属线或像素的透明绝缘材料制成。随着透光区域TA变得更大，第二显示区域CA的光透射率可更高。The light transmission area TA may include a transparent medium having high light transmittance without metal so that light may be incident with minimal light loss. The light transmitting area TA may be made of a transparent insulating material that does not include metal lines or pixels. As the light transmission area TA becomes larger, the light transmittance of the second display area CA may be higher.

多个第二像素组PG2的每一个可包括一个或两个像素。例如，在每个第二像素组PG2中，第一单位像素PIX1可包括R和G1子像素SP1、SP2，第二单位像素PIX2可包括B和G2子像素SP3、SP4。第二像素组PG2的像素的形状和布置可与第一像素组PG1的像素的形状和布置相同或不同。Each of the plurality of second pixel groups PG2 may include one or two pixels. For example, in each second pixel group PG2, the first unit pixel PIX1 may include R and G1 sub-pixels SP1, SP2, and the second unit pixel PIX2 may include B and G2 sub-pixels SP3, SP4. The shape and arrangement of pixels of the second pixel group PG2 may be the same as or different from those of the first pixel group PG1.

透光区域TA的形状被示出为是四边形形状，但本公开内容不限于此。例如，透光区域TA可设计为各种形状，诸如圆形形状、椭圆形形状、多边形形状等。The shape of the light transmitting area TA is shown as a quadrangular shape, but the present disclosure is not limited thereto. For example, the light-transmitting area TA may be designed in various shapes, such as a circular shape, an elliptical shape, a polygonal shape, and the like.

可从透光区域TA去除全部金属电极材料。因此，像素的各线TS可设置在透光区域TA外部。因此，光可通过透光区域有效地入射。然而，本公开内容不必限于此，在透光区域TA的部分区域中可存在金属电极材料。All metal electrode material may be removed from the light transmissive area TA. Accordingly, each line TS of a pixel may be disposed outside the light transmission area TA. Therefore, light can be efficiently incident through the light-transmitting region. However, the present disclosure is not necessarily limited thereto, and a metal electrode material may exist in a partial area of the light transmission area TA.

图6是图解第二显示区域的显示面板的结构的示意图，图7是图6的修改例。FIG. 6 is a schematic diagram illustrating a structure of a display panel of a second display area, and FIG. 7 is a modified example of FIG. 6 .

参照图6，显示面板可包括设置在基板10上的电路层12、和设置在电路层12上的发光元件层14。可在发光元件层14上设置偏振板18，并且可在偏振板18上设置盖玻璃20。Referring to FIG. 6 , the display panel may include acircuit layer 12 disposed on asubstrate 10 , and a light emittingelement layer 14 disposed on thecircuit layer 12 . Apolarizing plate 18 may be provided on the light emittingelement layer 14 , and acover glass 20 may be provided on thepolarizing plate 18 .

在偏振板18中，可在与透光区域TA对应的区域中形成第一透光图案18d。基于具有555nm波长的绿色光，由PI制成的基板的光透射率大约为70％至80％，并且阴极的光透射率为80％至90％。另一方面，偏振板18的光透射率相对非常低，大约为40％。因而，为了有效增加透光区域中的光透射率，需要增加偏振板18的光透射率。In thepolarizing plate 18, a firstlight transmission pattern 18d may be formed in an area corresponding to the light transmission area TA. Based on green light having a wavelength of 555 nm, the light transmittance of the substrate made of PI is about 70% to 80%, and the light transmittance of the cathode is 80% to 90%. On the other hand, the light transmittance of thepolarizing plate 18 is relatively very low, about 40%. Thus, in order to effectively increase the light transmittance in the light-transmitting region, it is necessary to increase the light transmittance of thepolarizing plate 18 .

根据该实施方式的偏振板18具有形成在透光区域TA上的第一透光图案18d，以增加光透射率。在偏振板中形成有第一透光图案的区域的光透射率可最高。因而，在透光区域中进入相机模块中的光量增加，从而提高相机性能。Thepolarizing plate 18 according to this embodiment has a firstlight transmission pattern 18d formed on the light transmission area TA to increase light transmittance. The light transmittance of a region where the first light-transmitting pattern is formed in the polarizing plate may be the highest. Thus, the amount of light entering the camera module in the light-transmitting region increases, thereby improving camera performance.

偏振板18的第一透光图案18d可通过去除偏振板18的一部分来形成，也可通过分解构成偏振板18的化合物来形成。就是说，第一透光图案18d可具有能够增加常规偏振板18的光透射率的各种结构。The first light-transmittingpattern 18d of thepolarizing plate 18 may be formed by removing a part of thepolarizing plate 18 or may be formed by decomposing a compound constituting thepolarizing plate 18 . That is, the firstlight transmitting pattern 18d may have various structures capable of increasing the light transmittance of the generalpolarizing plate 18 .

参照图7，在透光区域TA中，偏振板18可具有第一透光图案18d，并且阴极CAT可具有第二透光图案。第二透光图案可以是形成在透光区域TA中的开口H1。由于阴极的光透射率为80％至90％，所以透光区域TA的光透射率可由于开口H1而进一步增加。Referring to FIG. 7 , in the light transmission area TA, thepolarizing plate 18 may have a firstlight transmission pattern 18d, and the cathode CAT may have a second light transmission pattern. The second light transmission pattern may be an opening H1 formed in the light transmission area TA. Since the light transmittance of the cathode is 80% to 90%, the light transmittance of the light transmission area TA can be further increased due to the opening H1.

在阴极CAT中形成开口H1的方法没有特别限制。作为示例，在形成阴极之后，可使用蚀刻工艺在阴极中形成开口H1，或者可使用在基板10的下部的红外(IR)激光器去除阴极。A method of forming the opening H1 in the cathode CAT is not particularly limited. As an example, after the cathode is formed, the opening H1 may be formed in the cathode using an etching process, or the cathode may be removed using an infrared (IR) laser at a lower portion of thesubstrate 10 .

可在阴极CAT上形成偏振层PCL，并且可在偏振层PCL上设置触摸传感器TOE。在此，在透光区域TA中，触摸传感器的感测电极和线可由诸如氧化铟锡(ITO)之类的透明材料或金属网制成，从而增加光透射率。A polarizing layer PCL may be formed on the cathode CAT, and a touch sensor TOE may be disposed on the polarizing layer PCL. Here, in the light transmission area TA, the sensing electrodes and lines of the touch sensor may be made of a transparent material such as indium tin oxide (ITO) or a metal mesh, thereby increasing light transmittance.

参照图8和图9，第二显示区域CA可包括多个第二像素组PG2和多个透光区域TA。多个第二像素组PG2可沿第一方向和第二方向设置在多个像素行RW1至RW8和多个像素列中。下文中，第一方向可以是X轴方向，第二方向可以是Y1轴或Y2轴方向。在此，像素行和像素列可指设置多个子像素的行和列，透光区域可设置在行和列的部分区域或全部区域中。Referring to FIGS. 8 and 9 , the second display area CA may include a plurality of second pixel groups PG2 and a plurality of light transmitting areas TA. A plurality of second pixel groups PG2 may be disposed in a plurality of pixel rows RW1 to RW8 and a plurality of pixel columns along the first direction and the second direction.

根据该实施方式，第一至第三子像素SP1至SP3可实现为构成一个像素的真实型像素，但本公开内容不必限于此。作为示例，第二像素组PG2可进一步包括第四子像素，第四子像素可包括绿色发光元件或白色发光元件。每个发光元件可以是有机或无机发光元件。According to this embodiment, the first to third sub-pixels SP1 to SP3 may be implemented as true type pixels constituting one pixel, but the present disclosure is not necessarily limited thereto. As an example, the second pixel group PG2 may further include a fourth sub-pixel, and the fourth sub-pixel may include a green light emitting element or a white light emitting element. Each light emitting element may be an organic or inorganic light emitting element.

多个子像素SP1、SP2和SP3可沿第一方向或第二方向具有规则的布置。第一子像素SP1、第二子像素SP2和第三子像素SP3可沿第一方向顺序地设置。The plurality of sub-pixels SP1, SP2, and SP3 may have a regular arrangement along the first or second direction. The first subpixel SP1, the second subpixel SP2, and the third subpixel SP3 may be sequentially disposed along the first direction.

透光区域TA的宽度可对应于每个子像素的宽度。根据这种结构，可以以相对较小的结构设置大量的透光区域TA，使得可确保均匀的透光区域。然而，本公开内容不必限于此，透光区域的尺寸可进行各种调整。此外，尽管透光区域被示出为具有四边形形状，但也可应用圆形或多边形形状。The width of the light transmission area TA may correspond to the width of each sub-pixel. According to this structure, a large number of light-transmitting areas TA can be provided with a relatively small structure, so that uniform light-transmitting areas can be ensured. However, the present disclosure is not necessarily limited thereto, and the size of the light-transmitting region may be variously adjusted. Furthermore, although the light transmissive area is shown as having a quadrangular shape, a circular or polygonal shape may also be applied.

第一发光元件R与第三发光元件B可沿第一方向和第二方向交替设置。第二发光元件G1可在第一方向和第二方向上不与第一发光元件R和第三发光元件B重叠。The first light emitting elements R and the third light emitting elements B may be arranged alternately along the first direction and the second direction. The second light emitting element G1 may not overlap the first light emitting element R and the third light emitting element B in the first direction and the second direction.

第二发光元件G1与第三发光元件B可沿第一斜线方向D1交替设置，并且第二发光元件G1与第一发光元件R可沿第二斜线方向D2交替设置。第一斜线方向D1可以是Y1轴与X轴之间的斜线方向，第二斜线方向D2可以是Y2轴与X轴之间的斜线方向。The second light emitting elements G1 and the third light emitting elements B may be alternately arranged along the first oblique direction D1, and the second light emitting elements G1 and the first light emitting elements R may be alternately arranged along the second oblique direction D2. The first oblique direction D1 may be an oblique direction between the Y1 axis and the X axis, and the second oblique direction D2 may be an oblique direction between the Y2 axis and the X axis.

多个第二像素组PG2的第一发光元件R可设置在倾斜45°的第一方形线P1上。此外，第二发光元件G1可设置在第二方形线P2上，并且第三发光元件B可设置在第三方形线P3上。就是说，每个发光元件可设置为其中相同颜色的发光元件以四边形形状设置的结构。The first light emitting elements R of the plurality of second pixel groups PG2 may be disposed on the first square line P1 inclined at 45°. In addition, the second light emitting element G1 may be disposed on the second square line P2, and the third light emitting element B may be disposed on the third square line P3. That is, each light emitting element may be arranged in a structure in which light emitting elements of the same color are arranged in a quadrangular shape.

根据该实施方式，由于每个发光元件的中心(或每个子像素的中心)设置在方形线上，所以各个发光元件之间的距离变得均匀，使得具有甚至当省略一些像素时仍可实现相对均匀的图像质量的优点。此外，从外部不会观察到像素图案，使得可提高图像质量。According to this embodiment, since the center of each light-emitting element (or the center of each sub-pixel) is arranged on a square line, the distance between the respective light-emitting elements becomes uniform, making it possible to achieve a relative pixel even when some pixels are omitted. The advantage of uniform image quality. In addition, pixel patterns are not observed from the outside, so that image quality can be improved.

参照图9，在子像素SP1、SP2和SP3中可分别设置有电路部CT1、CT2和CT3。电路部CT1、CT2和CT3可各自包括与线TS连接的像素电路，以驱动像素。Referring to FIG. 9 , circuit parts CT1 , CT2 and CT3 may be disposed in the sub-pixels SP1 , SP2 and SP3 , respectively. The circuit parts CT1, CT2, and CT3 may each include a pixel circuit connected to the line TS to drive the pixel.

线TS可设置为绕过透光区域TA。在此，术语“绕过”可指线TS设置为尽可能少地覆盖透光区域TA。就是说，线可设置在部分透光区域中。此外，阴极的与透光区域TA对应的部分可被图案化，以增加光透射率。The line TS may be disposed to bypass the light-transmitting area TA. Here, the term "bypass" may mean that the wire TS is arranged to cover the light-transmitting area TA as little as possible. That is, the wires may be provided in partially light-transmitting regions. In addition, a portion of the cathode corresponding to the light transmission area TA may be patterned to increase light transmittance.

图10是图解根据本公开内容第二实施方式的第二显示区域中的像素布置的视图。图11a是图10的局部放大图。图11b是图11a的修改例。FIG. 10 is a view illustrating a pixel arrangement in a second display area according to a second embodiment of the present disclosure. FIG. 11 a is a partially enlarged view of FIG. 10 . Fig. 11b is a modified example of Fig. 11a.

第四子像素SP4可设置在与第一至第三子像素SP1至SP3不同的像素行中。作为示例，在第2-1像素组PG21中，第一至第三子像素SP1至SP3可设置在第一像素行RW1中，而第四子像素SP4可设置在第二像素行RW2中。第二子像素SP2的第二发光元件G1和第四子像素SP4的第四发光元件G2可沿第二斜线方向D2设置。The fourth sub-pixel SP4 may be disposed in a different pixel row from the first to third sub-pixels SP1 to SP3. As an example, in the 2-1 pixel group PG21, the first to third sub-pixels SP1 to SP3 may be disposed in the first pixel row RW1, and the fourth sub-pixel SP4 may be disposed in the second pixel row RW2. The second light emitting element G1 of the second subpixel SP2 and the fourth light emitting element G2 of the fourth subpixel SP4 may be disposed along the second oblique direction D2.

然而，本公开内容不必限于此，第四子像素SP4的电路部可形成在第一像素行RW1中并且第四发光元件G2的一部分可设置在第二像素行RW2中。就是说，表述“一个子像素设置在与其他子像素不同的像素行中”的含义可包括其中电路部和发光元件都设置在不同像素行中的情况、以及其中电路部和发光元件的至少一部分设置在不同像素行中的情况。However, the present disclosure is not necessarily limited thereto, and the circuit part of the fourth subpixel SP4 may be formed in the first pixel row RW1 and a part of the fourth light emitting element G2 may be provided in the second pixel row RW2. That is, the meaning of the expression "one sub-pixel is provided in a pixel row different from other sub-pixels" may include the case where both the circuit section and the light-emitting element are provided in a different pixel row, and the case where at least a part of the circuit section and the light-emitting element Cases set in different pixel rows.

相比之下，在第2-2像素组PG22中，第一子像素SP1、第三子像素SP3和第四子像素SP4可设置在第二像素行RW2中，而第二子像素SP2可设置在第一像素行RW1中。就是说，相邻的第2-1像素组PG21和第2-2像素组PG22可具有不同的像素布置。根据这种配置，第2-2像素组PG22的第二子像素SP2可设置于在第一方向上相邻的第2-1像素组PG21之间的透光区域TA中，从而提高均匀性和亮度。In contrast, in the 2-2 pixel group PG22, the first sub-pixel SP1, the third sub-pixel SP3, and the fourth sub-pixel SP4 may be disposed in the second pixel row RW2, and the second sub-pixel SP2 may be disposed In the first pixel row RW1. That is, adjacent 2-1 pixel groups PG21 and 2-2 pixel groups PG22 may have different pixel arrangements. According to this configuration, the second sub-pixel SP2 of the 2-2th pixel group PG22 can be disposed in the light-transmitting area TA between the 2-1st pixel group PG21 adjacent in the first direction, thereby improving uniformity and brightness.

第一发光元件R与第三发光元件B可沿第一方向交替设置。第二发光元件G1可在第一方向上不与第一发光元件R和第三发光元件B重叠。此外，第一发光元件R、第二发光元件G1和第三发光元件B可设置为在第二方向上彼此不重叠。The first light emitting elements R and the third light emitting elements B may be arranged alternately along the first direction. The second light emitting element G1 may not overlap the first light emitting element R and the third light emitting element B in the first direction. In addition, the first light emitting element R, the second light emitting element G1 and the third light emitting element B may be disposed not to overlap each other in the second direction.

第二发光元件G1或第四发光元件G2与第三发光元件B可沿第一斜线方向D1交替设置，并且第一发光元件R可在第一斜线方向D1上不与第二发光元件G1、第四发光元件G2和第三发光元件B重叠。The second light-emitting element G1 or the fourth light-emitting element G2 and the third light-emitting element B can be arranged alternately along the first oblique direction D1, and the first light-emitting element R can be separated from the second light-emitting element G1 in the first oblique direction D1. , the fourth light emitting element G2 and the third light emitting element B overlap.

第一发光元件R与第二发光元件G1和第四发光元件G2可沿第二斜线方向D2交替设置，并且第三发光元件B可在第二斜线方向D2上不与第一发光元件R、第二发光元件G1和第四发光元件G2重叠。The first light-emitting element R, the second light-emitting element G1 and the fourth light-emitting element G2 may be arranged alternately along the second oblique direction D2, and the third light-emitting element B may not be separated from the first light-emitting element R in the second oblique direction D2. , the second light emitting element G1 and the fourth light emitting element G2 overlap.

根据该布置，由于第二子像素SP2和第四子像素SP4可沿斜线方向均匀设置，所以与第一显示区域DA相比具有即使当省略一些像素时仍可实现均匀的图像质量的优点。此外，从外部不会观察到像素图案，使得可提高图像质量。According to this arrangement, since the second subpixel SP2 and the fourth subpixel SP4 can be uniformly arranged in the oblique direction, there is an advantage that uniform image quality can be achieved even when some pixels are omitted, compared to the first display area DA. In addition, pixel patterns are not observed from the outside, so that image quality can be improved.

尽管举例说明了可形成各种尺寸的多个透光区域TA的情况，但每个透光区域TA的尺寸可相同。作为示例，每个透光区域TA可具有与子像素的尺寸对应的尺寸。Although the case where a plurality of light transmitting areas TA may be formed in various sizes is exemplified, the size of each light transmitting area TA may be the same. As an example, each light transmitting area TA may have a size corresponding to the size of a sub-pixel.

参照图11b，透光区域TA可设置在构成第二像素组PG2的第三子像素SP3和第四子像素SP4之间。在第二像素组PG2之间的透光区域TA较大的情况下，存在相应的透光区域TA的亮度相对降低，使得图像质量劣化的问题，但是根据该实施方式，第四子像素SP4可设置在透光区域TA之间，使得可提高均匀性和亮度。Referring to FIG. 11b, the light transmitting area TA may be disposed between the third sub-pixel SP3 and the fourth sub-pixel SP4 constituting the second pixel group PG2. In the case where the light-transmitting area TA between the second pixel group PG2 is relatively large, there is a problem that the brightness of the corresponding light-transmitting area TA is relatively reduced, which degrades the image quality. However, according to this embodiment, the fourth sub-pixel SP4 can Disposed between the light-transmitting areas TA, so that uniformity and brightness can be improved.

作为示例，在第2-1像素组PG21中透光区域TA可设置在第三子像素SP3和第四子像素SP4之间，而在第2-2像素组PG22中透光区域TA可设置在第二子像素SP2和第三子像素SP3之间。此外，设置在第2-1像素组PG21中的透光区域TA的尺寸和设置在第2-2像素组PG22中的透光区域TA的尺寸可不同。As an example, in the 2-1 pixel group PG21, the light-transmitting area TA may be disposed between the third sub-pixel SP3 and the fourth sub-pixel SP4, and in the 2-2 pixel group PG22, the light-transmitting area TA may be disposed between Between the second sub-pixel SP2 and the third sub-pixel SP3. In addition, the size of the light-transmitting area TA disposed in the 2-1 pixel group PG21 and the size of the light-transmitting area TA disposed in the 2-2 pixel group PG22 may be different.

根据一实施方式，将多个子像素分组以形成像素组的方法可进行各种修改。图12是图解根据本公开内容第三实施方式的第二显示区域中的像素布置的视图。According to an embodiment, a method of grouping a plurality of sub-pixels to form a pixel group may be variously modified. FIG. 12 is a view illustrating a pixel arrangement in a second display area according to a third embodiment of the present disclosure.

参照图12，第一子像素SP1和第三子像素SP3可设置在第一像素行RW1中，而第二子像素SP2和第四子像素SP4可设置在第二像素行RW2中。Referring to FIG. 12 , the first and third subpixels SP1 and SP3 may be disposed in a first pixel row RW1 , and the second and fourth subpixels SP2 and SP4 may be disposed in a second pixel row RW2 .

因此，可在第一像素行RW1中交替设置第一发光元件R和第三发光元件B，并且可在第二像素行RW2中交替设置第二发光元件G1和第四发光元件G2。Accordingly, the first light emitting element R and the third light emitting element B may be alternately arranged in the first pixel row RW1, and the second light emitting element G1 and the fourth light emitting element G2 may be alternately arranged in the second pixel row RW2.

然而，本公开内容不必限于此，第二子像素SP2和第四子像素SP4的每一个的电路部可形成在第一像素行RW1中，并且第二发光元件G1和第四发光元件G2的每一个的一部分可设置在第二像素行RW2中。However, the present disclosure is not necessarily limited thereto, a circuit portion of each of the second subpixel SP2 and the fourth subpixel SP4 may be formed in the first pixel row RW1, and each of the second light emitting element G1 and the fourth light emitting element G2 A portion of one may be disposed in the second pixel row RW2.

此外，第二子像素SP2的第二发光元件G1和第四子像素SP4的第四发光元件G2可具有不同的形状。作为示例，第二发光元件G1可具有沿第二斜线方向D2延伸的形状，而第四发光元件G2可具有沿第一斜线方向D1延伸的形状。In addition, the second light emitting element G1 of the second subpixel SP2 and the fourth light emitting element G2 of the fourth subpixel SP4 may have different shapes. As an example, the second light emitting element G1 may have a shape extending in the second oblique direction D2, and the fourth light emitting element G2 may have a shape extending in the first oblique direction D1.

第二像素行RW2中的第二发光元件G1和第四像素行RW4中的第二发光元件G1也可被制造为具有不同的形状。就是说，第二发光元件G1可被制造为在第二方向上具有不同的形状。类似地，第二像素行RW2的第四发光元件G2和第四像素行RW4的第四发光元件G2可被制造为在第二方向上具有不同的形状。The second light emitting element G1 in the second pixel row RW2 and the second light emitting element G1 in the fourth pixel row RW4 may also be manufactured to have different shapes. That is, the second light emitting element G1 may be manufactured to have different shapes in the second direction. Similarly, the fourth light emitting element G2 of the second pixel row RW2 and the fourth light emitting element G2 of the fourth pixel row RW4 may be manufactured to have different shapes in the second direction.

由于发光元件以这种方式进行各种修改，所以当在基板上形成有机发光元件时，所以可不同地制造用于第一显示区域的精细金属掩模(Fine Metal Mask，FMM)和用于第二显示区域CA的FMM。Since the light emitting element is variously modified in this way, when the organic light emitting element is formed on the substrate, a Fine Metal Mask (FMM) for the first display area and a fine metal mask (FMM) for the second display area can be manufactured differently. 2 shows the FMM of the region CA.

作为示例，在用于第一显示区域的FMM中，可在第二发光元件G1和第四发光元件G2中形成具有相同形状的开口，而在用于第二显示区域的FMM中，可通过改变发光元件的形状和布置来形成开口，以有利于提高图像质量。因而，第一显示区域DA中的像素的形状和/或布置可与第二显示区域CA中的像素的形状和/或布置不同。As an example, in the FMM used for the first display area, openings having the same shape can be formed in the second light emitting element G1 and the fourth light emitting element G2, and in the FMM used for the second display area, openings can be formed by changing The shape and arrangement of the light emitting elements to form openings are beneficial to improve image quality. Thus, the shape and/or arrangement of pixels in the first display area DA may be different from the shape and/or arrangement of pixels in the second display area CA.

根据该实施方式，可通过不同地形成第一显示区域DA的发光元件和第二显示区域CA的发光元件的形状和/或布置提高均匀性和亮度。根据一实施方式，将多个子像素分组以形成像素组的方法可进行各种修改。According to this embodiment, uniformity and brightness may be improved by differently forming the shape and/or arrangement of the light emitting elements of the first display area DA and the light emitting elements of the second display area CA. According to an embodiment, a method of grouping a plurality of sub-pixels to form a pixel group may be variously modified.

图13是图解第二显示区域中的像素布置的第一比较例。图14图解了从外部是否识别到图案的观察结果。图15是图解第二显示区域中的像素布置的第二比较例。FIG. 13 is a first comparative example illustrating the arrangement of pixels in the second display area. FIG. 14 illustrates observation results of whether a pattern is recognized from the outside. FIG. 15 is a second comparative example illustrating the arrangement of pixels in the second display area.

参照图13，可在第一像素行RW1和第四像素行RW4的每一个中设置红色发光元件和蓝色发光元件，并且可在第二像素行RW2中设置绿色发光元件。在这种情况下，也可在第三像素行RW3中设置绿色发光元件。Referring to FIG. 13 , a red light emitting element and a blue light emitting element may be disposed in each of the first and fourth pixel rows RW1 and RW4 , and a green light emitting element may be disposed in the second pixel row RW2 . In this case, green light emitting elements may also be provided in the third pixel row RW3.

因此，由于在第二像素行RW2和第三像素行RW3中仅设置绿色发光元件，所以存在亮度均匀性相对降低的问题。结果，如图14中所示，从外部观察到线形图案Q1，因而存在图像质量劣化的问题。Therefore, since only green light emitting elements are disposed in the second pixel row RW2 and the third pixel row RW3 , there is a problem that brightness uniformity is relatively lowered. As a result, as shown in FIG. 14 , the linear pattern Q1 is observed from the outside, and thus there is a problem of image quality degradation.

参照图15，在第二像素行RW2和第三像素行RW3中仅设置绿色发光元件，因而存在从外部识别到线形图案的问题。相比之下，在本公开内容实施方式的情况下，由于子像素相对均匀地设置，所以具有提高图像质量的效果。Referring to FIG. 15 , only green light emitting elements are disposed in the second pixel row RW2 and the third pixel row RW3 , and thus there is a problem of recognizing the line pattern from the outside. In contrast, in the case of the embodiment of the present disclosure, since the sub-pixels are arranged relatively uniformly, there is an effect of improving image quality.

图16是图解根据本公开内容第四实施方式的第二显示区域中的像素布置的视图。图17是图解根据本公开内容第五实施方式的第二显示区域中的像素布置的视图。FIG. 16 is a view illustrating a pixel arrangement in a second display area according to a fourth embodiment of the present disclosure. FIG. 17 is a view illustrating a pixel arrangement in a second display area according to a fifth embodiment of the present disclosure.

参照图16，在第二像素组PG2中，第一子像素SP1和第二子像素SP2可设置在第一像素行RW1中，并且第三子像素SP3和第四子像素SP4可设置在第二像素行RW2中。16, in the second pixel group PG2, the first subpixel SP1 and the second subpixel SP2 may be disposed in the first pixel row RW1, and the third subpixel SP3 and the fourth subpixel SP4 may be disposed in the second pixel row RW1. pixel row RW2.

此外，第二子像素SP2和第三子像素SP3可沿第二斜线方向D2设置，并且第一子像素SP1和第三子像素SP3可沿第一斜线方向D1设置。透光区域TA可设置在多个第二像素组PG2之间。透光区域TA也可形成为对应于第二像素组PG2的尺寸。In addition, the second subpixel SP2 and the third subpixel SP3 may be disposed along the second oblique direction D2, and the first subpixel SP1 and the third subpixel SP3 may be disposed along the first oblique direction D1. The light transmitting area TA may be disposed between the plurality of second pixel groups PG2. The light transmitting area TA may also be formed to correspond to the size of the second pixel group PG2.

参照图17，在第二像素组PG2中，第一子像素SP1和第二子像素SP2可设置在第一像素行RW1中，并且第三子像素SP3和第四子像素SP4可设置在第二像素行RW2中。17, in the second pixel group PG2, the first subpixel SP1 and the second subpixel SP2 may be disposed in the first pixel row RW1, and the third subpixel SP3 and the fourth subpixel SP4 may be disposed in the second pixel row RW1. pixel row RW2.

此外，第一子像素SP1和第四子像素SP4可沿第二斜线方向D2设置，并且第二子像素SP2和第三子像素SP3可沿第一斜线方向D1设置。透光区域TA可设置在多个第二像素组PG2之间。透光区域TA也可形成为对应于第二像素组PG2的尺寸。In addition, the first subpixel SP1 and the fourth subpixel SP4 may be disposed along the second oblique direction D2, and the second subpixel SP2 and the third subpixel SP3 may be disposed along the first oblique direction D1. The light transmitting area TA may be disposed between the plurality of second pixel groups PG2. The light transmitting area TA may also be formed to correspond to the size of the second pixel group PG2.

图18是图解根据本公开内容第六实施方式的第二显示区域中的像素布置的视图。图19是图解根据本公开内容第七实施方式的第二显示区域中的像素布置的视图。FIG. 18 is a view illustrating a pixel arrangement in a second display area according to a sixth embodiment of the present disclosure. FIG. 19 is a view illustrating a pixel arrangement in a second display area according to a seventh embodiment of the present disclosure.

参照图18，在第二像素组PG2中，第一至第四子像素SP1、SP2、SP3和SP4可设置在同一像素行中。第二像素组PG2与透光区域TA可沿第一方向和第二方向交替设置。在此，透光区域TA的尺寸可对应于第二像素组PG2的尺寸。Referring to FIG. 18 , in the second pixel group PG2 , first to fourth subpixels SP1 , SP2 , SP3 and SP4 may be disposed in the same pixel row. The second pixel group PG2 and the transparent area TA may be alternately arranged along the first direction and the second direction. Here, the size of the light transmission area TA may correspond to the size of the second pixel group PG2.

参照图19，第二像素组PG2包括第一至第四子像素SP1、SP2、SP3和SP4，并且第二像素组PG2与透光区域TA可沿第一方向交替设置。在第二方向上，第2-1像素组PG21与第2-2像素组PG22可交替设置。在第2-1像素组PG21和第2-2像素组PG22中，第一子像素SP1和第三子像素SP3的位置可彼此不同。Referring to FIG. 19 , the second pixel group PG2 includes first to fourth sub-pixels SP1 , SP2 , SP3 and SP4 , and the second pixel group PG2 and the light transmission area TA may be alternately arranged along the first direction. In the second direction, the 2-1 pixel group PG21 and the 2-2 pixel group PG22 may be arranged alternately. In the 2-1 pixel group PG21 and the 2-2 pixel group PG22, the positions of the first sub-pixel SP1 and the third sub-pixel SP3 may be different from each other.

图20是图解根据本公开内容第八实施方式的第二显示区域中的像素布置的视图，图21是图20的放大图，图22是图21的一修改例，图23是图21的第二修改例。20 is a view illustrating a pixel arrangement in a second display area according to an eighth embodiment of the present disclosure, FIG. 21 is an enlarged view of FIG. 20 , FIG. 22 is a modified example of FIG. 21 , and FIG. Two modified examples.

参照图20，在第二像素组PG2中，第一子像素SP1、第二子像素SP2和第三子像素SP3可沿第一方向设置，并且第四子像素SP4可沿第三子像素SP3的第二斜线方向D2设置。Referring to FIG. 20 , in the second pixel group PG2, the first subpixel SP1, the second subpixel SP2, and the third subpixel SP3 may be arranged along the first direction, and the fourth subpixel SP4 may be arranged along the direction of the third subpixel SP3. The second oblique direction D2 is set.

透光区域TA可设置在多个第二像素组PG2之间。在这种情况下，透光区域TA可包括与每个子像素的宽度对应的区域和与三个子像素的宽度对应的区域。就是说，多个透光区域TA的尺寸可彼此不同。然而，本公开内容不必限于此，多个透光区域TA的尺寸也可相同。The light transmitting area TA may be disposed between the plurality of second pixel groups PG2. In this case, the light transmitting area TA may include an area corresponding to the width of each sub-pixel and an area corresponding to the width of three sub-pixels. That is, the sizes of the plurality of transmissive areas TA may be different from each other. However, the present disclosure is not necessarily limited thereto, and the sizes of the plurality of light-transmitting areas TA may also be the same.

第一至第三子像素SP1、SP2和SP3可沿第一方向交替设置。第四子像素SP4可在第一方向上不与第一至第三子像素SP1、SP2和SP3重叠。第一至第四子像素SP1、SP2、SP3和SP4可设置为在第二方向上彼此不重叠。The first to third sub-pixels SP1, SP2 and SP3 may be alternately arranged along the first direction. The fourth subpixel SP4 may not overlap the first to third subpixels SP1, SP2, and SP3 in the first direction. The first to fourth sub-pixels SP1, SP2, SP3, and SP4 may be disposed not to overlap each other in the second direction.

多个第二像素组PG2的第一至第四子像素SP1、SP2、SP3和SP4可设置在方形线P1、P2、P3和P4的每一个上。此外，第一至第三子像素SP1、SP2和SP3可设置在将第四子像素SP4连接的方形线P4内部。根据该布置，由于所有子像素均匀地设置，所以即使当与第一显示区域DA相比省略了一些像素，也可实现均匀的图像质量。此外，不会从外部观察到像素图案，使得可提高图像质量。The first to fourth sub-pixels SP1, SP2, SP3 and SP4 of the plurality of second pixel groups PG2 may be disposed on each of the square lines P1, P2, P3 and P4. In addition, the first to third subpixels SP1, SP2, and SP3 may be disposed inside a square line P4 connecting the fourth subpixel SP4. According to this arrangement, even when some pixels are omitted compared with the first display area DA, uniform image quality can be achieved since all sub-pixels are uniformly arranged. In addition, pixel patterns are not observed from the outside, so that image quality can be improved.

在该实施方式中，描述了第四子像素SP4设置在与第一至第三子像素SP1至SP3不同的像素行中，但本公开内容不必限于此。第四子像素SP4的电路部可形成在第一像素行RW1中，并且第四发光元件的一部分可设置在第二像素行RW2中。In this embodiment, it is described that the fourth sub-pixel SP4 is disposed in a different pixel row from the first to third sub-pixels SP1 to SP3, but the present disclosure is not necessarily limited thereto. A circuit part of the fourth subpixel SP4 may be formed in the first pixel row RW1, and a part of the fourth light emitting element may be disposed in the second pixel row RW2.

参照图21，第二显示区域CA可包括其中多个第二像素组PG2沿第一方向连续设置的奇数像素行RW3和RW5、以及其中多个透光区域TA沿第一方向连续设置的偶数像素行RW2和RW4，奇数像素行RW3和RW5与偶数像素行RW2和RW4可沿第二方向交替设置。Referring to FIG. 21 , the second display area CA may include odd-numbered pixel rows RW3 and RW5 in which a plurality of second pixel groups PG2 are continuously arranged along the first direction, and even-numbered pixels in which a plurality of light-transmitting areas TA are continuously arranged along the first direction. The rows RW2 and RW4, the odd pixel rows RW3 and RW5 and the even pixel rows RW2 and RW4 may be alternately arranged along the second direction.

设置在奇数像素行RW3和RW5的每一个中的子像素SP1、SP2、SP3和SP4的电路部CT1、CT2、CT3和CT4可沿第一方向连续设置。因而，因为在子像素之间未设置透光区域TA，所以优点在于简化了线设计。当在子像素之间设置多个透光区域时，线设计会变得复杂，因为线必须绕过透光区域。The circuit parts CT1 , CT2 , CT3 and CT4 of the subpixels SP1 , SP2 , SP3 and SP4 disposed in each of the odd pixel rows RW3 and RW5 may be continuously disposed in the first direction. Thus, since the light-transmitting area TA is not provided between the sub-pixels, there is an advantage in that the line design is simplified. When multiple light-transmitting regions are provided between sub-pixels, the line design becomes complicated because the lines have to go around the light-transmitting regions.

第四子像素SP4的电路部CT4可与第一至第三发光元件的电路部CT1、CT2和CT3一起沿第一方向连续设置。就是说，每个子像素的电路部可连续形成在第三像素行RW3中。因而，设置在第四像素行RW4中的透光区域TA可连续设置。The circuit part CT4 of the fourth sub-pixel SP4 may be continuously disposed along the first direction together with the circuit parts CT1 , CT2 and CT3 of the first to third light emitting elements. That is, the circuit part of each sub-pixel may be continuously formed in the third pixel row RW3. Thus, the light transmissive areas TA disposed in the fourth pixel row RW4 may be continuously disposed.

设置在第三像素行RW3中的透光区域TA可被数据线DL划分为多个区域。然而，本公开内容不必限于此，透光区域TA的尺寸可根据数据线的设计变化而变化。The light transmitting area TA disposed in the third pixel row RW3 may be divided into a plurality of areas by the data line DL. However, the present disclosure is not necessarily limited thereto, and the size of the light-transmissive area TA may vary according to design variations of the data lines.

将第二像素组PG2中的第二发光元件G1和第四发光元件G2的每一个的中心连接的第一虚拟线FL1可与第一方向和第二方向交叉。就是说，第二发光元件G1和第四发光元件G2可在之间夹有第三发光元件B的情况下沿第二斜线方向D2设置。The first imaginary line FL1 connecting the center of each of the second light emitting element G1 and the fourth light emitting element G2 in the second pixel group PG2 may cross the first direction and the second direction. That is, the second light emitting element G1 and the fourth light emitting element G2 may be disposed in the second oblique direction D2 with the third light emitting element B interposed therebetween.

第二发光元件G1可设置在穿过第一发光元件R和第三发光元件B的每一个的中心的第二虚拟线FL2的一侧(上侧)，并且第四发光元件G2可设置在第二虚拟线FL2的另一侧(下侧)。然而，本公开内容不必限于此，第二发光元件G1可设置在第二虚拟线FL2的下侧并且第四发光元件G2可设置在第二虚拟线FL2的上侧。The second light emitting element G1 may be disposed on one side (upper side) of the second imaginary line FL2 passing through the center of each of the first light emitting element R and the third light emitting element B, and the fourth light emitting element G2 may be disposed on the second imaginary line FL2. The other side (lower side) of the second imaginary line FL2. However, the present disclosure is not necessarily limited thereto, and the second light emitting element G1 may be disposed on a lower side of the second imaginary line FL2 and the fourth light emitting element G2 may be disposed on an upper side of the second imaginary line FL2.

根据该实施方式，第一虚拟线FL1可与第二虚拟线FL2交叉。因此，第四发光元件G2的一部分可设置为与透光区域TA重叠。在此，设置在第四发光元件G2下面的阳极也可延伸到透光区域TA上。根据该配置，可通过将第四发光元件G2部分地设置在透光区域TA中提高亮度和均匀性。According to this embodiment, the first imaginary line FL1 may cross the second imaginary line FL2. Therefore, a part of the fourth light emitting element G2 may be disposed to overlap the light-transmissive area TA. Here, the anode disposed under the fourth light emitting element G2 may also extend to the light-transmissive area TA. According to this configuration, luminance and uniformity can be improved by partially disposing the fourth light emitting element G2 in the light transmission area TA.

图解了第四发光元件G2的一部分设置在透光区域TA外部，但本公开内容不必限于此。作为示例，第四发光元件G2可设置在透光区域TA的中央。在这种情况下，阳极可延伸以将电路部CT4和第四发光元件G2连接。阳极可形成为透明电极，但本公开内容不必限于此。It is illustrated that a part of the fourth light emitting element G2 is disposed outside the light transmission area TA, but the present disclosure is not necessarily limited thereto. As an example, the fourth light emitting element G2 may be disposed at the center of the light transmission area TA. In this case, the anode may extend to connect the circuit portion CT4 and the fourth light emitting element G2. The anode may be formed as a transparent electrode, but the present disclosure is not necessarily limited thereto.

根据该实施方式，由于第四发光元件G2设置在透光区域TA中，所以设置在第三像素行RW3中的第四发光元件G2与设置在第五像素行RW5中的第二发光元件G1之间的第一距离W1可相对较小。第一距离W1可大致与同一第二像素组PG2中的第二发光元件G1与第四发光元件G2之间的第二距离W2相似。According to this embodiment, since the fourth light-emitting element G2 is disposed in the light-transmitting area TA, the difference between the fourth light-emitting element G2 disposed in the third pixel row RW3 and the second light-emitting element G1 disposed in the fifth pixel row RW5 The first distance W1 between them may be relatively small. The first distance W1 may be substantially similar to the second distance W2 between the second light emitting element G1 and the fourth light emitting element G2 in the same second pixel group PG2.

因而，即使当在第三像素行RW3中连续设置多个透光区域TA时，也可在第二显示区域CA中规则地布置第二发光元件G1与第四发光元件G2之间的距离，使得亮度可以是均匀的。此外，可提高图像质量。Thus, even when a plurality of light-transmitting areas TA are continuously provided in the third pixel row RW3, the distance between the second light emitting element G1 and the fourth light emitting element G2 can be regularly arranged in the second display area CA such that Brightness can be uniform. In addition, image quality can be improved.

与每个子像素连接的线TS可配置为避开透光区域TA。作为示例，与每个子像素连接的诸如数据线、扫描线和EM线之类的线TS可被设计为尽可能地绕过透光区域TA。作为示例，从第一显示区域DA的第四像素行RW4延伸的线TS可被设计为绕行到第二显示区域CA中的第五像素行RW5。The line TS connected to each sub-pixel may be configured to avoid the light-transmitting area TA. As an example, lines TS such as data lines, scan lines, and EM lines connected to each sub-pixel may be designed to bypass the light-transmitting area TA as much as possible. As an example, the line TS extending from the fourth pixel row RW4 in the first display area DA may be designed to detour to the fifth pixel row RW5 in the second display area CA.

阴极的与透光区域TA对应的部分可被图案化，以增加光透射率。此外，如上所述，也可在偏振板上形成对应于透光区域的第一透光图案，以增加光透射率。A portion of the cathode corresponding to the light transmitting area TA may be patterned to increase light transmittance. In addition, as described above, the first light-transmitting pattern corresponding to the light-transmitting region may also be formed on the polarizing plate to increase the light transmittance.

参照图22，第二发光元件G1而不是第四发光元件G2可设置在透光区域TA中。可选择地，第二发光元件G1可与设置在其下侧的透光区域TA相邻设置，并且第四发光元件G2可与设置在其上侧的透光区域TA相邻设置。在这种情况下，发光元件可设置在透光区域TA中，从而提高图像质量。Referring to FIG. 22 , the second light emitting element G1 may be disposed in the light transmitting area TA instead of the fourth light emitting element G2. Alternatively, the second light emitting element G1 may be disposed adjacent to the light transmission area TA disposed on the lower side thereof, and the fourth light emitting element G2 may be disposed adjacent to the light transmission area TA disposed on the upper side thereof. In this case, the light emitting element may be disposed in the light transmission area TA, thereby improving image quality.

参照图23，第四发光元件G2可在不被电路部单独控制的情况下通过与第二发光元件G1的电路部CT1连接而用作发光的虚拟像素。在这种情况下，可进一步形成连接在第四发光元件G2与第二发光元件G1之间的连接线XL1。连接线XL1可被制造为透明电极，诸如ITO，但本公开内容不必限于此。Referring to FIG. 23 , the fourth light emitting element G2 may be used as a dummy pixel emitting light by being connected with the circuit part CT1 of the second light emitting element G1 without being individually controlled by the circuit part. In this case, a connection line XL1 connected between the fourth light emitting element G2 and the second light emitting element G1 may be further formed. The connection line XL1 may be manufactured as a transparent electrode such as ITO, but the present disclosure is not necessarily limited thereto.

图24a是图解根据本公开内容第九实施方式的第二显示区域中的像素布置的视图。FIG. 24a is a view illustrating a pixel arrangement in a second display area according to a ninth embodiment of the present disclosure.

参照图24a，多个第二像素组PG2可设置为沿第一方向彼此分隔开。与图20的沿第一方向连续设置的第二像素组PG2相比，在图24a中，在多个第二像素组PG2之间还设置透光区域TA，因而像素的数量与图20的第二显示区域相比可减少1/2。因此，光可充分地入射到增加的透光区域TA上。Referring to FIG. 24a, a plurality of second pixel groups PG2 may be arranged to be spaced apart from each other along the first direction. Compared with the second pixel group PG2 continuously arranged along the first direction in FIG. 20, in FIG. 24a, a light-transmitting area TA is also provided between the plurality of second pixel groups PG2, so the number of pixels is the same as that of the second pixel group PG2 in FIG. Compared with the second display area, it can be reduced by 1/2. Therefore, light may be sufficiently incident on the increased light transmission area TA.

设置在多个第二像素组PG2中的每个子像素可设置在倾斜45°的方形线上。作为示例，多个第一子像素SP1可设置在第一方形线P1上，多个第二子像素SP2可设置在第二方形线P2上，并且多个第三子像素SP3可设置在第三方形线P3上。Each sub-pixel disposed in the plurality of second pixel groups PG2 may be disposed on a square line inclined at 45°. As an example, a plurality of first subpixels SP1 may be disposed on a first square line P1, a plurality of second subpixels SP2 may be disposed on a second square line P2, and a plurality of third subpixels SP3 may be disposed on a second square line P1. On the triangular line P3.

图24b是图解在第二显示区域中透光区域的面积变化的结构的视图。FIG. 24b is a view illustrating a structure in which an area of a light-transmitting region changes in a second display region.

参照图24b，第二显示区域CA可包括：具有比第一显示区域DA数量少的像素的第一单位区域CA2；和具有比第一单位区域CA2数量少的像素的第二单位区域CA1。就是说，甚至在第二显示区域CA中分辨率也可不同。Referring to FIG. 24b, the second display area CA may include: a first unit area CA2 having a smaller number of pixels than the first display area DA; and a second unit area CA1 having a smaller number of pixels than the first unit area CA2. That is, the resolution may be different even in the second display area CA.

可在第二显示区域CA下方设置多个电子器件。作为示例，多个电子器件可包括确定周围亮度的环境光传感器(Ambient light sensor)、接近传感器(Proximity sensor)、内置有图像传感器的相机模块、以及接收红外光的红外传感器。相机模块42a包括红外滤波器，以阻断红外波段的光并且接收可见光，而红外传感器42b可接收红外波段的光。A plurality of electronic devices may be disposed under the second display area CA. As examples, the plurality of electronic devices may include an ambient light sensor to determine ambient brightness, a proximity sensor, a camera module with an image sensor built in, and an infrared sensor to receive infrared light. Thecamera module 42a includes an infrared filter to block light in the infrared band and receive visible light, and theinfrared sensor 42b can receive light in the infrared band.

在此，与相机模块42a相比，即使当光量较小时红外传感器42b仍可进行相对精确的测量。因而，设置相机模块42a的第二单位区域CA1的像素数量可少于设置红外传感器42b的第一单位区域CA2的像素数量。Here, compared with thecamera module 42a, theinfrared sensor 42b can perform relatively accurate measurement even when the amount of light is small. Thus, the number of pixels of the second unit area CA1 where thecamera module 42a is disposed may be less than the number of pixels of the first unit area CA2 where theinfrared sensor 42b is disposed.

作为示例，第二单位区域CA1的像素图案PA1可具有图24a中所示的像素图案，第一单位区域CA2的像素图案PA2可具有图20中所示的像素图案。作为示例，第一单位区域CA2可被设计为具有10％至30％的光透射率。因而，在第二单位区域CA1中入射光的量可相对较大。然而，这种像素图案不必限于此，可没有限制地应用本申请中描述的像素图案。As an example, the pixel pattern PA1 of the second unit area CA1 may have the pixel pattern shown in FIG. 24 a , and the pixel pattern PA2 of the first unit area CA2 may have the pixel pattern shown in FIG. 20 . As an example, the first unit area CA2 may be designed to have a light transmittance of 10% to 30%. Thus, the amount of incident light in the second unit area CA1 may be relatively large. However, such pixel patterns are not necessarily limited thereto, and the pixel patterns described in this application may be applied without limitation.

In this case, the number of pixels is reduced by 1/2 compared to the first display area DA, so that a sufficient amount of light can be injected into the sensor.

多个第二像素组PG2的第一至第四子像素SP1、SP2、SP3和SP4可设置在方形线P1、P2、P3和P4的每一个上。根据该布置，由于所有子像素均匀地设置，所以即使当与第一显示区域DA相比省略了一些像素，也可实现均匀的图像质量。此外，不会从外部观察到像素图案，使得可提高图像质量。The first to fourth sub-pixels SP1, SP2, SP3 and SP4 of the plurality of second pixel groups PG2 may be disposed on each of the square lines P1, P2, P3 and P4. According to this arrangement, even when some pixels are omitted compared with the first display area DA, uniform image quality can be achieved since all sub-pixels are uniformly arranged. In addition, pixel patterns are not observed from the outside, so that image quality can be improved.

参照图26，将第二发光元件G1和第四发光元件G2连接的第三虚拟线FL3可与第一方向平行。该像素布置与第一显示区域的像素步骤相同。Referring to FIG. 26 , a third imaginary line FL3 connecting the second light emitting element G1 and the fourth light emitting element G2 may be parallel to the first direction. The pixel arrangement is the same as the pixel step of the first display area.

与每个子像素连接的线TS可配置为避开透光区域TA。作为示例，与每个子像素连接的数据线、扫描线和EM线可被设计为尽可能地绕过透光区域TA。此外，阴极的与透光区域TA对应的部分可被图案化，以增加光透射率。The line TS connected to each sub-pixel may be configured to avoid the light-transmitting area TA. As an example, data lines, scan lines, and EM lines connected to each sub-pixel may be designed to bypass the light-transmitting area TA as much as possible. In addition, a portion of the cathode corresponding to the light transmission area TA may be patterned to increase light transmittance.

参照图27，多个第二像素组PG2可设置为沿第一方向彼此分隔开。与图25的沿第一方向连续设置的第二像素组PG2相比，透光区域TA设置在图27的多个第二像素组PG2之间，因而像素的数量可进一步减少。因此，光可充分地入射到增加的透光区域TA上。Referring to FIG. 27 , a plurality of second pixel groups PG2 may be arranged to be spaced apart from each other along the first direction. Compared with the second pixel group PG2 continuously arranged along the first direction of FIG. 25 , the light-transmitting area TA is disposed between the plurality of second pixel groups PG2 of FIG. 27 , and thus the number of pixels can be further reduced. Therefore, light may be sufficiently incident on the increased light transmission area TA.

设置在多个第二像素组PG2中的子像素SP1、SP2、SP3和SP4的每一个可设置在倾斜45°的方形线上。作为示例，多个第一子像素SP1可设置在第一方形线P1上，多个第二子像素SP2可设置在第二方形线P2上，多个第三子像素SP3可设置在第三方形线P3上，并且多个第四子像素SP4可设置在第四方形线P4上。Each of the sub-pixels SP1, SP2, SP3, and SP4 disposed in the plurality of second pixel groups PG2 may be disposed on a square line inclined at 45°.

在本公开内容的显示装置中，设置在电路层12上的像素电路和栅极驱动单元可包括多个晶体管。晶体管可实现为包括氧化物半导体的氧化物薄膜晶体管(Oxide Thin FilmTransistor，Oxide TFT)、包括低温多晶硅(Low Temperature Poly Silicon，LTPS)的LTPSTFT等。每个晶体管可实现为p沟道薄膜晶体管(TFT)或n沟道TFT。将关注于像素电路的晶体管实现为p沟道TFT的示例描述下面的实施方式，但本公开内容不限于此。In the display device of the present disclosure, the pixel circuit and the gate driving unit disposed on thecircuit layer 12 may include a plurality of transistors. The transistor may be realized as an oxide thin film transistor (Oxide Thin Film Transistor, Oxide TFT) including an oxide semiconductor, an LTP STFT including a low temperature polysilicon (Low Temperature Poly Silicon, LTPS), or the like. Each transistor may be implemented as a p-channel thin film transistor (TFT) or an n-channel TFT. The following embodiments are described focusing on an example in which a transistor of a pixel circuit is realized as a p-channel TFT, but the present disclosure is not limited thereto.

晶体管是包括栅极(gate)、源极(source)和漏极(drain)的三电极元件。源极是给晶体管提供载流子(carrier)的电极。晶体管中的载流子可从源极开始流动。漏极是供载流子从晶体管离开到外部的电极。A transistor is a three-electrode element including a gate, a source, and a drain. The source is an electrode that provides carriers to the transistor. Carriers in a transistor can flow from the source. The drain is an electrode for the exit of carriers from the transistor to the outside.

在晶体管中，载流子从源极流动到漏极。在n沟道晶体管的情况下，载流子是电子(electron)，因而源极电压低于漏极电压，使得电子从源极流动到漏极。在n沟道晶体管的情况下，电流从漏极流动到源极。In a transistor, carriers flow from source to drain. In the case of an n-channel transistor, the carriers are electrons, so the source voltage is lower than the drain voltage, allowing electrons to flow from the source to the drain. In the case of n-channel transistors, current flows from the drain to the source.

在p沟道晶体管(PMOS)的情况下，载流子是空穴(hole)，因而源极电压高于漏极电压，使得空穴从源极流动到漏极。在p沟道晶体管的情况下，由于空穴从源极流动到漏极，所以电流从源极流动到漏极。应当注意，晶体管的源极和漏极的位置不是固定的。例如，源极和漏极可根据施加的电压互换。因此，本公开内容不受晶体管的源极和漏极限制。在下面的描述中，晶体管的源极和漏极将被称为第一电极和第二电极。In the case of a p-channel transistor (PMOS), the carriers are holes, so the source voltage is higher than the drain voltage, allowing the holes to flow from the source to the drain. In the case of p-channel transistors, as holes flow from source to drain, current flows from source to drain. It should be noted that the positions of the source and drain of the transistor are not fixed. For example, source and drain can be interchanged depending on the applied voltage. Therefore, the present disclosure is not limited by the sources and drains of transistors. In the following description, the source and drain of the transistor will be referred to as a first electrode and a second electrode.

栅极脉冲可在栅极导通电压(Gate On Voltage)与栅极截止电压(Gate OffVoltage)之间摆动(swing)。栅极导通电压可设为高于晶体管的阈值电压，栅极截止电压可设为低于晶体管的阈值电压。The gate pulse can swing between a gate on voltage (Gate On Voltage) and a gate off voltage (Gate Off Voltage). The gate-on voltage can be set higher than the threshold voltage of the transistor, and the gate-off voltage can be set lower than the threshold voltage of the transistor.

晶体管可响应于栅极导通电压导通(turn-on)并且响应于栅极截止电压截止(turn-off)。在n沟道晶体管的情况下，栅极导通电压可以是栅极高电压(Gate HighVoltage，VGH)，栅极截止电压可以是栅极低电压(Gate Low Voltage，VGL)。在p沟道晶体管的情况下，栅极导通电压可以是VGL，栅极截止电压可以是VGH。The transistor is turn-on in response to a gate-on voltage and turn-off in response to a gate-off voltage. In the case of an n-channel transistor, the gate-on voltage may be a gate high voltage (Gate High Voltage, VGH), and the gate-off voltage may be a gate low voltage (Gate Low Voltage, VGL). In the case of a p-channel transistor, the gate-on voltage may be VGL, and the gate-off voltage may be VGH.

像素电路的驱动元件可实现为晶体管。驱动元件应在所有像素之间具有均匀的电特性，但是由于工艺变化和元件特性变化，在像素之间会具有电特性的差异，并且显示驱动时间流逝，电特性会变化。The driving elements of the pixel circuit may be implemented as transistors. The driving element should have uniform electrical characteristics among all pixels, but due to process variations and element characteristic variations, there will be differences in electrical characteristics between pixels, and the electrical characteristics will vary with the lapse of display driving time.

为了补偿驱动元件的电特性变化，显示装置可包括内部补偿电路和外部补偿电路。内部补偿电路可被添加到每个子像素中的像素电路，以采样根据驱动元件的电特性而变化的驱动元件的阈值电压Vth和/或迁移率μ，并且实时补偿所述变化。In order to compensate for variations in electrical characteristics of driving elements, a display device may include an internal compensation circuit and an external compensation circuit. An internal compensation circuit may be added to the pixel circuit in each sub-pixel to sample threshold voltage Vth and/or mobility μ of a driving element that varies according to electrical characteristics of the driving element, and compensate for the variation in real time.

外部补偿电路可将通过与每个子像素连接的感测线感测的驱动元件的阈值电压和/或迁移率传送到外部补偿单元。外部补偿电路的补偿单元可反映感测结果来调制输入图像的像素数据，从而补偿驱动元件的电特性的变化。The external compensation circuit may transmit the threshold voltage and/or mobility of the driving element sensed through the sensing line connected to each sub-pixel to the external compensation unit. The compensation unit of the external compensation circuit may reflect the sensing result to modulate the pixel data of the input image, thereby compensating for the variation of the electrical characteristics of the driving element.

可感测根据外部补偿驱动元件的电特性而变化的像素的电压，并且基于感测的电压在外部电路中调制输入图像的数据，从而补偿像素之间的驱动元件的电特性的变化。A voltage of a pixel varying according to an electrical characteristic of an externally compensating driving element may be sensed, and data of an input image is modulated in an external circuit based on the sensed voltage, thereby compensating for variation in the electrical characteristic of the driving element between pixels.

The threshold voltage Vth of the driving element DT is compensated by the gate voltage of the driving element DT to the threshold voltage Vth of the driving element DT. Each of the driving element DT and the switching elements M1 to M6 can be realized as a p-channel TFT.

使用内部补偿电路的像素电路的驱动时段可分为初始化时段Tini、采样时段Tsam、数据写入时段Twr和发光时段Tem，如图38中所示。The driving period of the pixel circuit using the internal compensation circuit can be divided into an initialization period Tini, a sampling period Tsam, a data writing period Twr, and a light emission period Tem, as shown in FIG. 38 .

在初始化时段Tini期间，第N-1扫描信号SCAN(N-1)被生成为栅极导通电压VGL的脉冲，并且第N扫描信号SCAN(N)和发光信号EM(N)的每一个的电压是栅极截止电压VGH。在采样时段Tsam期间，第N扫描信号SCAN(N)被生成为栅极导通电压VGL的脉冲，并且第N-1扫描信号SCAN(N-1)和发光信号EM(N)的每一个的电压是栅极截止电压VGH。在数据写入时段Twr期间，第N-1扫描信号SCAN(N-1)、第N扫描信号SCAN(N)和发光信号EM(N)的每一个的电压是栅极截止电压VGH。在发光时段Tem的至少部分时段期间，发光信号EM(N)可被生成为栅极导通电压VGL，并且第N-1扫描信号SCAN(N-1)和第N扫描信号SCAN(N)的每一个电压可被生成为栅极截止电压VGH。During the initialization period Tini, the N-1th scan signal SCAN(N-1) is generated as a pulse of the gate-on voltage VGL, and each of the Nth scan signal SCAN(N) and the light emitting signal EM(N) The voltage is the gate-off voltage VGH. During the sampling period Tsam, the N-th scan signal SCAN(N) is generated as a pulse of the gate-on voltage VGL, and each of the N-1-th scan signal SCAN(N-1) and the light emission signal EM(N) The voltage is the gate-off voltage VGH. During the data writing period Twr, the voltage of each of the N-1th scan signal SCAN(N-1), the Nth scan signal SCAN(N), and the light emission signal EM(N) is the gate-off voltage VGH. During at least a part of the light emission period Tem, the light emission signal EM(N) may be generated as the gate-on voltage VGL, and the N-1th scan signal SCAN(N-1) and the Nth scan signal SCAN(N) Each voltage may be generated as a gate-off voltage VGH.

在初始化时段Tini期间，第五开关元件M5可根据第N-1扫描信号SCAN(N-1)的栅极导通电压VGL导通，以将像素电路初始化。在采样时段Tsam期间，第一开关元件M1和第二开关元件M2可根据第N扫描信号SCAN(N)的栅极导通电压VGL导通，使得驱动元件DT的阈值电压可被采样并存储在存储电容器Cst1中。同时，第六开关元件M6可在采样时段Tsam期间导通，以将第四节点n4的电压降低至基准电压Vref，从而抑制发光元件OLED的发光。在数据写入时段Twr期间，第一至第六开关元件M1至M6可保持在截止状态。在发光时段Tem期间，第三开关元件M3和第四开关元件M4可导通，使得发光元件OLED发光。在发光时段Tem中，为了利用发光信号EM(N)的占空比(duty ration)精确地呈现低灰度的亮度，发光信号EM(N)可以以预定的占空比在栅极导通电压VGL与栅极截止电压VGH之间摆动，以重复第三开关元件M3和第四开关元件M4的导通或截止。During the initialization period Tini, the fifth switching element M5 may be turned on according to the gate-on voltage VGL of the N-1th scan signal SCAN(N-1) to initialize the pixel circuit. During the sampling period Tsam, the first switching element M1 and the second switching element M2 may be turned on according to the gate-on voltage VGL of the Nth scan signal SCAN(N), so that the threshold voltage of the driving element DT may be sampled and stored in storage capacitor Cst1. Meanwhile, the sixth switching element M6 may be turned on during the sampling period Tsam to reduce the voltage of the fourth node n4 to the reference voltage Vref, thereby suppressing the light emission of the light emitting element OLED. During the data writing period Twr, the first to sixth switching elements M1 to M6 may be maintained in a turn-off state. During the light emitting period Tem, the third switching element M3 and the fourth switching element M4 may be turned on so that the light emitting element OLED emits light. In the light-emitting period Tem, in order to accurately present low-gray-scale luminance by using the duty ratio of the light-emitting signal EM(N), the light-emitting signal EM(N) can be turned on at the gate voltage at a predetermined duty ratio. VGL swings between the gate-off voltage VGH to repeatedly turn on or off the third switching element M3 and the fourth switching element M4.

发光元件OLED可实现为有机发光二极管或无机发光二极管。下文中，将描述发光元件OLED实现为有机发光二极管的示例。The light emitting element OLED can be realized as an organic light emitting diode or an inorganic light emitting diode. Hereinafter, an example in which the light emitting element OLED is realized as an organic light emitting diode will be described.

发光元件OLED可包括形成在阳极与阴极之间的有机化合物层。有机化合物层可包括空穴注入层HIL、空穴传输层HTL、发光层EML、电子传输层ETL和电子注入层EIL，但本公开内容不限于此。当电压施加至OLED的阳极和阴极时，穿过空穴传输层HTL的空穴和穿过电子传输层ETL的电子移动到发光层EML以产生激子，因而可从发光层EML发射可见光。The light emitting element OLED may include an organic compound layer formed between an anode and a cathode. The organic compound layer may include a hole injection layer HIL, a hole transport layer HTL, an emission layer EML, an electron transport layer ETL, and an electron injection layer EIL, but the present disclosure is not limited thereto. When a voltage is applied to the anode and cathode of the OLED, holes passing through the hole transport layer HTL and electrons passing through the electron transport layer ETL move to the emission layer EML to generate excitons, and thus visible light can be emitted from the emission layer EML.

发光元件OLED的阳极可连接至第四开关元件M4与第六开关元件M6之间的第四节点n4。第四节点n4连接至发光元件OLED的阳极、第四开关元件M4的第二电极和第六开关元件M6的第二电极。发光元件OLED的阴极可连接至被施加低电位电源电压VSS的VSS线PL3。发光元件OLED可利用根据驱动元件DT的栅极-源极电压Vgs而流动的电流Ids发光。第三开关元件M3和第四开关元件M4可切换发光元件OLED的电流路径。An anode of the light emitting element OLED may be connected to a fourth node n4 between the fourth switching element M4 and the sixth switching element M6. The fourth node n4 is connected to the anode of the light emitting element OLED, the second electrode of the fourth switching element M4, and the second electrode of the sixth switching element M6. A cathode of the light emitting element OLED may be connected to a VSS line PL3 to which a low-potential power supply voltage VSS is applied. The light emitting element OLED may emit light using the current Ids flowing according to the gate-source voltage Vgs of the driving element DT. The third switching element M3 and the fourth switching element M4 can switch the current path of the light emitting element OLED.

存储电容器Cst1可连接在VDD线PL1与第一节点n1之间。存储电容器Cst1可被充电上被补偿了驱动元件DT的阈值电压Vth的数据电压Vdata。由于每个子像素中的数据电压Vdata被补偿了驱动元件DT的阈值电压Vth，所以每个子像素中的驱动元件DT的特性偏差可被补偿。The storage capacitor Cst1 may be connected between the VDD line PL1 and the first node n1. The storage capacitor Cst1 may be charged with the data voltage Vdata compensated for the threshold voltage Vth of the driving element DT. Since the data voltage Vdata in each sub-pixel is compensated by the threshold voltage Vth of the driving element DT, a characteristic deviation of the driving element DT in each sub-pixel may be compensated.

A first electrode of the first switching element M1 may be connected to the second node n2, and a second electrode of the first switching element M1 may be connected to the third node n3.

第一开关元件M1可在一个帧时段中的、其中第N扫描信号SCAN(N)被生成为栅极导通电压VGL的一个非常短的水平时段1H中导通，因而可在大约一个帧时段中保持在截止状态，因此在第一开关元件M1的截止状态中可能产生漏电流。为了抑制第一开关元件M1的漏电流，第一开关元件M1可实现为具有串联连接的两个晶体管M1a和M1b的双栅(dual-gate)结构，如图37中所示。The first switching element M1 can be turned on in a very short horizontal period 1H in which the N-th scan signal SCAN(N) is generated as the gate-on voltage VGL in one frame period, and thus can be turned on for about one frame period. is kept in an off state, and thus leakage current may be generated in the off state of the first switching element M1. In order to suppress the leakage current of the first switching element M1, the first switching element M1 may be realized in a dual-gate structure having two transistors M1a and M1b connected in series, as shown in FIG. 37 .

A gate electrode of the fourth switching element M4 may be connected to the third gate line GL3 to receive the light emitting signal EM(N). A first electrode of the fourth switching element M4 may be connected to the third node n3, and a second electrode of the fourth switching element M4 may be connected to the fourth node n4.

第五开关元件M5可响应于第N-1扫描信号SCAN(N-1)的栅极导通电压VGL导通，以将第二节点n2连接至Vini线PL2。第五开关元件M5的栅极电极可连接至第二栅极线GL2，以接收第N-1扫描信号SCAN(N-1)。第五开关元件M5的第一电极可连接至第二节点n2，并且第五开关元件M5的第二电极可连接至Vini线PL2。为了抑制第五开关元件M5的漏电流，第五开关元件M5可实现为具有串联连接的两个晶体管M5a和M5b的双栅(结构，如图37中所示。The fifth switching element M5 may be turned on in response to the gate-on voltage VGL of the N-1th scan signal SCAN(N-1) to connect the second node n2 to the Vini line PL2. A gate electrode of the fifth switching element M5 may be connected to the second gate line GL2 to receive the N-1th scan signal SCAN(N-1). A first electrode of the fifth switching element M5 may be connected to the second node n2, and a second electrode of the fifth switching element M5 may be connected to the Vini line PL2. In order to suppress the leakage current of the fifth switching element M5, the fifth switching element M5 may be implemented as a double gate (structure) having two transistors M5a and M5b connected in series, as shown in FIG. 37 .

第六开关元件M6可响应于第N扫描信号SCAN(N)的栅极导通电压VGL导通，以将Vini线PL2连接至第四节点n4。第六开关元件M6的栅极电极可连接至第一栅极线GL1，以接收第N扫描信号SCAN(N)。第六开关元件M6的第一电极可连接至Vini线PL2，并且第六开关元件M6的第二电极可连接至第四节点n4。The sixth switching element M6 may be turned on in response to the gate-on voltage VGL of the Nth scan signal SCAN(N) to connect the Vini line PL2 to the fourth node n4.

The driving element DT may include a gate electrode connected to the second node n2, a first electrode connected to the first node n1, and a second electrode connected to the third node n3.

如图38中所示，第N-1扫描信号SCAN(N-1)在初始化时段Tini期间被生成为栅极导通电压VGL。在初始化时段Tini期间，第N扫描信号SCAN(N)和发光信号EM(N)可保持在栅极截止电压VGH。因而，在初始化时段Tini期间，第五开关元件M5可导通(turn-on)，使得第二节点n2和第四节点n4各自可被初始化为“Vini”。可在初始化时段Tini与采样时段Tsam之间设定保持时段Th。在保持时段Th期间，栅极信号SCAN(N-1)、SCAN(N)和EM(N)可保持在它们之前的状态。As shown in FIG. 38 , the N-1th scan signal SCAN(N-1) is generated as the gate-on voltage VGL during the initialization period Tini. During the initialization period Tini, the Nth scan signal SCAN(N) and the light emitting signal EM(N) may be maintained at the gate-off voltage VGH. Thus, during the initialization period Tini, the fifth switching element M5 may be turned on (turn-on), so that each of the second node n2 and the fourth node n4 may be initialized to "Vini". The hold period Th can be set between the initialization period Tini and the sampling period Tsam. During the holding period Th, the gate signals SCAN(N−1), SCAN(N), and EM(N) may be maintained in their previous states.

在采样时段Tsam期间，第N扫描信号SCAN(N)可被生成为栅极导通电压VGL。第N扫描信号SCAN(N)可与第N像素线的数据电压Vdata同步。在采样时段Tsam期间，第N-1扫描信号SCAN(N-1)和发光信号EM(N)各自可保持在栅极截止电压。因而，在采样时段Tsam期间，第一开关元件M1和第二开关元件M2可导通。During the sampling period Tsam, the N-th scan signal SCAN(N) may be generated as the gate-on voltage VGL. The Nth scan signal SCAN(N) may be synchronized with the data voltage Vdata of the Nth pixel line. During the sampling period Tsam, each of the N-1th scan signal SCAN(N-1) and the emission signal EM(N) may be maintained at the gate-off voltage. Thus, during the sampling period Tsam, the first switching element M1 and the second switching element M2 may be turned on.

在采样时段Tsam期间，驱动元件DT的栅极电压DTG可由于流过第一开关元件M1和第二开关元件M2的电流而升高。当驱动元件DT截止时，栅极电压DTG是Vdata-|Vth|。在这种情况下，第一节点n1的电压也为Vdata-|Vth|。在采样时段Tsam期间，驱动元件DT的栅极-源极电压Vgs为|Vgs|＝Vdata-(Vdata-|Vth|)＝|Vth|。During the sampling period Tsam, the gate voltage DTG of the driving element DT may increase due to the current flowing through the first switching element M1 and the second switching element M2. When the driving element DT is turned off, the gate voltage DTG is Vdata-|Vth|. In this case, the voltage of the first node n1 is also Vdata-|Vth|. During the sampling period Tsam, the gate-source voltage Vgs of the driving element DT is |Vgs|=Vdata-(Vdata-|Vth|)=|Vth|.

在数据写入时段Twr期间，第N扫描信号SCAN(N)可反转为栅极截止电压VGH。在数据写入时段Twr期间，第N-1扫描信号SCAN(N-1)和发光信号EM(N)各自可保持在栅极截止电压VGH。因而，在数据写入时段Twr期间，所有开关元件M1至M6可保持在截止状态。During the data writing period Twr, the N-th scan signal SCAN(N) may be inverted to the gate-off voltage VGH. During the data writing period Twr, each of the N-1th scan signal SCAN(N-1) and the light emitting signal EM(N) may be maintained at the gate-off voltage VGH. Thus, during the data writing period Twr, all the switching elements M1 to M6 may be maintained in an off state.

在发光时段Tem期间，发光信号EM(N)可被生成为栅极导通电压VGL。在发光时段Tem期间，为了提高低灰度呈现，发光信号EM(N)可以以预定的占空比导通或截止，以在栅极导通电压VGL与栅极截止电压VGH之间摆动(swing)。因此，发光信号EM(N)可在发光时段Tem的至少部分时段被生成为栅极导通电压VGL。During the light emission period Tem, the light emission signal EM(N) may be generated as the gate turn-on voltage VGL. During the light emission period Tem, in order to enhance the low grayscale representation, the light emission signal EM(N) may be turned on or off at a predetermined duty ratio to swing between the gate-on voltage VGL and the gate-off voltage VGH. ). Accordingly, the light emitting signal EM(N) may be generated as the gate-on voltage VGL during at least part of the light emitting period Tem.

当发光信号EM(N)处于栅极导通电压VGL时，电流在“VDD”与发光元件OLED之间流动，使得发光元件OLED可发光。在发光时段Tem期间，第N-1扫描信号SCAN(N-1)和第N扫描信号SCAN(N)各自可保持在栅极截止电压VGH。在发光时段Tem期间，第三开关元件M3和第四开关元件M4可根据发光信号EM(N)的电压反复导通和截止。当发光信号EM(N)处于栅极导通电压VGL时，第三开关元件M3和第四开关元件M4导通，使得电流流入发光元件OLED中。在这种情况下，驱动元件DT的“Vgs”满足|Vgs|＝VDD-(Vdata-|Vth|)，并且流入发光元件OLED中的电流为K(VDD-Vdata)2。“K”是由驱动元件DT的电荷迁移率、寄生电容和沟道容量确定的常数。When the light emission signal EM(N) is at the gate-on voltage VGL, current flows between "VDD" and the light emitting element OLED, so that the light emitting element OLED can emit light. During the light emission period Tem, each of the N-1th scan signal SCAN(N-1) and the Nth scan signal SCAN(N) may be maintained at the gate-off voltage VGH. During the light emitting period Tem, the third switching element M3 and the fourth switching element M4 may be repeatedly turned on and off according to the voltage of the light emitting signal EM(N). When the light emitting signal EM(N) is at the gate-on voltage VGL, the third switching element M3 and the fourth switching element M4 are turned on, so that current flows into the light emitting element OLED. In this case, "Vgs" of the driving element DT satisfies |Vgs|=VDD-(Vdata-|Vth|), and the current flowing into the light-emitting element OLED is K(VDD-Vdata)2. "K" is a constant determined by the charge mobility, parasitic capacitance, and channel capacity of the driving element DT.
