技术领域technical field

本发明涉及显示技术领域，具体地说，涉及一种显示面板及其制作方法、显示装置。The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device.

背景技术Background technique

OLED(Organic Light-Emitting Diode，有机发光二极管)显示面板与传统的LCD显示面板(Liquid Crystal Display，液晶显示面板)相比，不需要背光源，可实现自发光，具有结构简单、轻薄、亮度高、发光效率好、宽视角、可折叠等优势，在穿戴、手机、平板、电脑等领域具有广泛应用。Compared with the traditional LCD display panel (Liquid Crystal Display, liquid crystal display panel), OLED (Organic Light-Emitting Diode, organic light-emitting diode) display panel does not need a backlight, can realize self-illumination, and has the advantages of simple structure, light weight and high brightness. , good luminous efficiency, wide viewing angle, foldable and other advantages, it has a wide range of applications in wearables, mobile phones, tablets, computers and other fields.

OLED器件采用薄的有机材料和玻璃基板组成，通过驱动电路产生电流控制有机材料发光。OLED器件的驱动电路由各种图案化的金属走线组成，具有较强的反射，会影响屏幕的出光效果。现有技术中为了降低OLED器件的反射，通常贴附偏光片。但偏光片存在透过率较差以及功耗大的缺点，会使得OLED器件的功耗明显增加。The OLED device is composed of a thin organic material and a glass substrate, and the organic material is controlled to emit light by generating a current through a driving circuit. The driving circuit of the OLED device is composed of various patterned metal traces, which have strong reflection and will affect the light-emitting effect of the screen. In the prior art, in order to reduce the reflection of the OLED device, a polarizer is usually attached. However, the polarizer has the disadvantages of poor transmittance and high power consumption, which will significantly increase the power consumption of the OLED device.

所以存在现有技术采用滤光片，这能够降低OLED器件的反射，并且相比于采用偏光片的方案改善了功耗。但会出于设备精度、OLED像素设计或者光学效果考虑等，滤光片中的彩膜会存在不同的开口尺寸。当彩膜的开口尺寸大于OLED像素尺寸时，由于未被黑色矩阵遮盖的驱动电路层中金属走线部分的反射率较高，使得OLED面板的整体反射率会增加，OLED面板的出光效果变差，不利于OLED面板的显示效果。Therefore, there is an existing technology that uses an optical filter, which can reduce the reflection of the OLED device and improve the power consumption compared to the solution using a polarizer. However, due to equipment accuracy, OLED pixel design or optical effect considerations, etc., the color filter in the filter will have different opening sizes. When the opening size of the color filter is larger than the OLED pixel size, the overall reflectivity of the OLED panel will increase due to the high reflectivity of the metal traces in the driving circuit layer that is not covered by the black matrix, and the light output effect of the OLED panel will deteriorate. , which is not conducive to the display effect of the OLED panel.

图1是现有技术中的显示面板的结构示意图。如图1所示，现有技术中的显示面板包括依次叠设的驱动电路层101、有机发光层、薄膜封装层104、彩色滤光层以及封装盖板107。有机发光层包括OLED像素102以及用于界定出OLED像素102所在区域的像素定义层103。彩色滤光层包括设置在OLED像素102上方的彩膜105以及设于相邻彩膜105之间的黑色矩阵106。彩膜105与OLED像素102相对应，且彩膜105用于使OLED像素102发出的光透过。由于黑色矩阵106的光透过率几乎为零，因此OLED像素102发出的光只能从彩膜105透过。FIG. 1 is a schematic structural diagram of a display panel in the prior art. As shown in FIG. 1 , a display panel in the prior art includes adriving circuit layer 101 , an organic light-emitting layer, a thinfilm encapsulation layer 104 , a color filter layer and anencapsulation cover plate 107 that are stacked in sequence. The organic light-emitting layer includes theOLED pixels 102 and apixel definition layer 103 for defining a region where theOLED pixels 102 are located. The color filter layer includes acolor filter 105 disposed above theOLED pixels 102 and ablack matrix 106 disposed between adjacent color filters 105 . Thecolor filter 105 corresponds to theOLED pixel 102 , and thecolor filter 105 is used to transmit the light emitted by theOLED pixel 102 . Since the light transmittance of theblack matrix 106 is almost zero, the light emitted by theOLED pixels 102 can only be transmitted through thecolor filter 105 .

当彩膜105的开口尺寸大于OLED像素102的开口尺寸时(如图1所示的圆角矩形框即为开口大于的部分)，比如可能出于增加大视角亮度衰减角度的考虑等，此时也即，彩膜105在整个显示面板上的占比增加，相应地会导致黑色矩阵106在整个面板上的占比减小，由于彩膜105的反射率大于黑色矩阵106的反射率，因此，未被黑色矩阵106遮盖的驱动电路层中金属走线部分的反射率也较高，将导致OLED面板的出光效果较差，不利于OLED面板的显示效果。When the opening size of thecolor filter 105 is larger than the opening size of the OLED pixel 102 (the rounded rectangular frame shown in FIG. 1 is the part with the larger opening), for example, it may be due to the consideration of increasing the brightness attenuation angle of the large viewing angle, etc. That is to say, the proportion of thecolor filter 105 on the entire display panel increases, and accordingly, the proportion of theblack matrix 106 on the entire panel decreases. Since the reflectivity of thecolor filter 105 is greater than that of theblack matrix 106, therefore, The reflectivity of the metal trace portion in the driving circuit layer not covered by theblack matrix 106 is also high, which will lead to poor light extraction effect of the OLED panel, which is not conducive to the display effect of the OLED panel.

如图2所示，本发明一实施例公开了一种显示面板。该显示面板包括依次叠设的基板201、驱动电路层202、有机发光层、薄膜封装层301以及彩色滤光层。有机发光层位于上述基板201的一侧，上述有机发光层包括OLED像素203以及用于界定出上述OLED像素203所在区域的像素定义层204。具体而言，有机发光层包括像素定义层204以及由像素定义层204界定出的像素区域，像素区域内设置有上述OLED像素203。驱动电路层202位于上述基板201与有机发光层之间。As shown in FIG. 2, an embodiment of the present invention discloses a display panel. The display panel includes asubstrate 201, a drivingcircuit layer 202, an organic light-emitting layer, a thinfilm encapsulation layer 301 and a color filter layer that are stacked in sequence. The organic light-emitting layer is located on one side of thesubstrate 201 , and the organic light-emitting layer includesOLED pixels 203 and apixel definition layer 204 for defining the region where theOLED pixels 203 are located. Specifically, the organic light-emitting layer includes apixel definition layer 204 and a pixel area defined by thepixel definition layer 204, and the above-mentionedOLED pixels 203 are disposed in the pixel area. The drivingcircuit layer 202 is located between the above-mentionedsubstrate 201 and the organic light-emitting layer.

薄膜封装层301位于上述有机发光层背离上述基板201的一侧，包括多层具有透光部205和非透光部206的有机薄膜。上述非透光部206采用黑色不透光材质或填充有抗反射颗粒。也即，薄膜封装层301由无机薄膜207和有机薄膜交替层叠形成，其中有机薄膜具有透光部205和非透光部206。透光部205基于基板201的投影与OLED像素203基于基板201的投影重合。The thinfilm encapsulation layer 301 is located on the side of the organic light-emitting layer away from thesubstrate 201 , and includes multiple layers of organic thin films having a light-transmittingportion 205 and a non-light-transmittingportion 206 . The above-mentionednon-transparent part 206 is made of black opaque material or filled with anti-reflection particles. That is, the thinfilm encapsulation layer 301 is formed by alternately laminating inorganicthin films 207 and organic thin films, wherein the organic thin films have light-transmittingparts 205 and non-light-transmittingparts 206 . The projection of the light-transmittingportion 205 based on thesubstrate 201 coincides with the projection of theOLED pixel 203 based on thesubstrate 201 .

上述黑色不透光材质可以是感光树脂组成物，该感光树脂组成物可以包括粘合剂树脂、光可聚合单体、光聚合起始剂、黑色着色剂及溶剂等。上述抗反射颗粒可以包括碳粉颗粒，该抗反射颗粒可以采用二氧化钛等材料制成。The black opaque material can be a photosensitive resin composition, and the photosensitive resin composition can include a binder resin, a photopolymerizable monomer, a photopolymerization initiator, a black colorant, a solvent, and the like. The above-mentioned anti-reflection particles may include carbon powder particles, and the anti-reflection particles may be made of materials such as titanium dioxide.

其中，彩色滤光层位于薄膜封装层301背离基板201的一侧，彩色滤光层包括设置在上述OLED像素203上方的彩膜208，以及设于相邻彩膜208之间的黑色矩阵209。上述彩膜208基于上述基板201形成第一投影区域，上述OLED像素203基于上述基板201形成第二投影区域，上述薄膜封装层301中有机薄膜的非透光部206基于上述基板201形成第三投影区域。上述第一投影区域中去除上述第一投影区域与上述第二投影区域的交集区域后的区域形成第四投影区域。上述第三投影区域覆盖上述第四投影区域。也就是说，第三投影区域包含上述第四投影区域。The color filter layer is located on the side of the thinfilm encapsulation layer 301 away from thesubstrate 201 . The color filter layer includes acolor filter 208 disposed above theOLED pixels 203 and ablack matrix 209 between adjacent color filters 208 . Thecolor filter 208 forms a first projection area based on thesubstrate 201 , theOLED pixel 203 forms a second projection area based on thesubstrate 201 , and thenon-transparent portion 206 of the organic thin film in the thinfilm encapsulation layer 301 forms a third projection based on thesubstrate 201 area. A fourth projection area is formed from an area of the first projection area after removing the intersection area of the first projection area and the second projection area. The third projection area covers the fourth projection area. That is, the third projection area includes the above-mentioned fourth projection area.

本实施例通过在薄膜封装层301中的有机薄膜层设置成采用黑色不透光材质或填充有抗反射颗粒的非透光部206，对驱动电路层202中的金属走线部分透出的反射光实现遮盖，可以降低该金属走线部分的反射率，有利于降低OLED器件反射率，提升OLED显示面板的显示效果。In this embodiment, by setting the organic thin film layer in the thinfilm encapsulation layer 301 to use a black opaque material or thenon-transmissive part 206 filled with anti-reflection particles, the reflection reflected by the metal trace part in thedriving circuit layer 202 is reflected. Covering the light can reduce the reflectivity of the metal wiring portion, which is beneficial to reduce the reflectivity of the OLED device and improve the display effect of the OLED display panel.

在本申请的另一实施例中，如图3所示，在上述任一实施例的基础上，上述彩色滤光层中的黑色矩阵209与上述彩膜208的接触面均为倾斜的坡面，且上述黑色矩阵209的端面形成的第一坡面随着上述黑色矩阵209与上述基板201之间距离的增加而远离上述彩膜208，随着上述黑色矩阵209与上述基板201之间距离的逐渐减小而逐渐靠近上述彩膜208。该黑色矩阵209的材质为黑色不透光材质。In another embodiment of the present application, as shown in FIG. 3 , on the basis of any of the above embodiments, the contact surfaces of theblack matrix 209 in the color filter layer and thecolor filter 208 are both inclined slopes , and the first slope formed by the end face of theblack matrix 209 is away from thecolor filter 208 as the distance between theblack matrix 209 and thesubstrate 201 increases, and as the distance between theblack matrix 209 and thesubstrate 201 increases It gradually decreases and gets closer to the above-mentionedcolor filter 208 . The material of theblack matrix 209 is a black opaque material.

该实施例中，利用黑色矩阵209来遮挡驱动电路层202中的金属走线部分透出的反射光，有利于降低OLED器件反射率，提升OLED显示面板的显示效果。In this embodiment, theblack matrix 209 is used to block the reflected light transmitted by the metal traces in thedriving circuit layer 202, which is beneficial to reduce the reflectivity of the OLED device and improve the display effect of the OLED display panel.

可选地，在另一实施例中，在上述任一实施例的基础上，上述第一坡面所在平面经过上述OLED像素203靠近上述基板201一侧的端面的中心点，且上述第一坡面与上述显示面板的厚度方向之间形成的夹角(如图3所示的α)范围为0°～80°。Optionally, in another embodiment, on the basis of any of the foregoing embodiments, the plane where the first slope is located passes through the center point of the end surface of theOLED pixel 203 on the side of thesubstrate 201 , and the first slope is The included angle (α as shown in FIG. 3 ) formed between the surface and the thickness direction of the display panel ranges from 0° to 80°.

图3中的α也即为大视角亮度衰减角度，这样通过对黑色矩阵209与彩膜208的接触端面采用倾斜图案化设计，在保证OLED面板低反射率的同时增加了大视角亮度衰减角度，有利于增强OLED面板的户外可视功能，避免了需要增大彩膜208开口尺寸而导致增大OLED面板反射率的问题。α in FIG. 3 is also the large viewing angle brightness attenuation angle. In this way, by adopting an inclined pattern design for the contact end face of theblack matrix 209 and thecolor filter 208, the large viewing angle brightness attenuation angle is increased while ensuring the low reflectivity of the OLED panel. It is beneficial to enhance the outdoor viewing function of the OLED panel, and avoids the problem of increasing the reflectivity of the OLED panel due to the need to increase the opening size of thecolor filter 208 .

需要说明的是，该实施例中的薄膜封装层301可以采用上述实施例中的结构设计，也可以采用现有技术中的常规封装结构设计，即利用常规结构的薄膜封装层实现的上述实施例也在本申请的保护范围之内。It should be noted that, the thin-film encapsulation layer 301 in this embodiment can adopt the structural design in the above-mentioned embodiment, or can adopt the conventional encapsulation structure design in the prior art, that is, the above-mentioned embodiment realized by using the thin-film encapsulating layer of the conventional structure It is also within the scope of protection of the present application.

在本申请的另一实施例中，在上述任一实施例的基础上，上述像素定义层204的材质为上述黑色不透光材质。这样利用黑色不透光材质的像素定义层204遮挡驱动电路层202中的金属走线部分透出的反射光，可以降低该金属走线部分的反射率，有利于降低OLED器件反射率，提升OLED显示面板的显示效果。In another embodiment of the present application, on the basis of any of the above embodiments, the material of thepixel definition layer 204 is the black opaque material. In this way, thepixel definition layer 204 made of black opaque material is used to block the reflected light transmitted by the metal wiring part in thedriving circuit layer 202, which can reduce the reflectivity of the metal wiring part, which is beneficial to reduce the reflectivity of the OLED device and improve the OLED The display effect of the display panel.

在另一实施例中，如图4所示，在上述任一实施例的基础上，上述像素定义层204背离基板201的一侧表面涂敷有黑色不透光材料，形成黑色像素定义层401。这样可以在满足遮挡驱动电路层202中的金属走线部分透出的反射光的前提下，只需对像素定义层204一侧表面采用黑色不透光材料制成，有利于节省工艺，降低面板制作成本以及制作时间。In another embodiment, as shown in FIG. 4 , on the basis of any of the above-mentioned embodiments, the side surface of thepixel definition layer 204 facing away from thesubstrate 201 is coated with a black opaque material to form a blackpixel definition layer 401 .
