技术领域technical field
本发明涉及液晶显示领域，特别是指一种液晶显示面板及其制作方法、液晶显示器。The invention relates to the field of liquid crystal displays, in particular to a liquid crystal display panel, a manufacturing method thereof, and a liquid crystal display.
背景技术Background technique
传统的液晶显示器包括第一基板、第二基板、透明电极和设置于第一基板和第二基板之间的液晶层，在第一基板上还设置有彩膜层，彩膜层包括多个像素单元，每个像素单元包括三个子像素，分别为红色子像素、绿色子像素和蓝色子像素，每个子像素区域分别设置有一个薄膜晶体管，用于控制子像素区域的液晶分子偏转，由于液晶分子偏转透过的光线再通过彩膜层得到红绿蓝三色光，通过控制红绿蓝三色光的强度可以得到不同的显示颜色，从而显示彩色图像。传统的液晶显示器一般在制作时需要单独通过构图工艺来制作彩膜层，工艺比较复杂。A traditional liquid crystal display includes a first substrate, a second substrate, a transparent electrode and a liquid crystal layer arranged between the first substrate and the second substrate, and a color filter layer is also arranged on the first substrate, and the color filter layer includes a plurality of pixels Each pixel unit includes three sub-pixels, which are red sub-pixels, green sub-pixels and blue sub-pixels, and each sub-pixel area is respectively provided with a thin film transistor for controlling the deflection of liquid crystal molecules in the sub-pixel area. The light transmitted through the molecular deflection passes through the color filter layer to obtain red, green and blue three-color light. By controlling the intensity of red, green and blue three-color light, different display colors can be obtained, thereby displaying color images. Traditional liquid crystal displays generally require a separate patterning process to make the color filter layer during production, and the process is relatively complicated.
目前，产生了一种半透半反式液晶显示模式，同时具有透射式和反射式特性，半透半反式液晶面板在一个像素域内包括有透明电极的透射区域和有反射层的反射区域。在黑暗的地方可以利用像素区域的透射区域和背光源来显示画像，在明亮的地方利用像素区域的反射区域和外光来显示画像。因此，半透半反式液晶显示器不需要时时使用背光源，因而具有可以降低功耗的优点。但传统的半透半反式液晶显示模式存在反射区域亮度低的问题，因为在反射区域入射光两次通过彩膜，而导致透过率降低，使反射区域和透射区域显示的亮度不同，也就是说半透半反式液晶面板会出现彩色不平衡的问题。为了解决该问题，传统的半透半反式液晶显示模式采用在彩膜上加工LightHole(透光洞)来提高反射区域的透过率，但这样就大大提高了制造工艺的复杂性。At present, a transflective liquid crystal display mode has been produced, which has both transmissive and reflective characteristics. The transflective liquid crystal panel includes a transmissive area with a transparent electrode and a reflective area with a reflective layer in a pixel domain. In a dark place, images can be displayed by using the transmissive area of the pixel area and the backlight, and in a bright place, the image can be displayed by using the reflective area of the pixel area and external light. Therefore, the transflective liquid crystal display does not need to use a backlight all the time, and thus has the advantage of reducing power consumption. However, the traditional transflective liquid crystal display mode has the problem of low brightness in the reflective area, because the incident light in the reflective area passes through the color film twice, resulting in a decrease in transmittance, which makes the display brightness of the reflective area and the transmissive area different, and also That is to say, there will be a problem of color imbalance in the transflective LCD panel. In order to solve this problem, the traditional transflective liquid crystal display mode adopts processing LightHole (light hole) on the color filter to improve the transmittance of the reflective area, but this greatly increases the complexity of the manufacturing process.

As shown in FIG. The substrate 22 is provided with a reflective region 32 and a transmissive region 31. Correspondingly, the color display layer 25 includes a plurality of pixel units, and each pixel unit includes six sub-pixels, respectively the first transmissive sub-pixel 251, the second transmissive sub-pixel A sub-pixel 252 , a third transmissive blue sub-pixel 253 , a first reflective sub-pixel 254 , a second reflective sub-pixel 255 , and a third reflective sub-pixel 256 .

The pixel unit in this solution preferably includes red, green and blue three-color pixels, but is not limited to this three-color pixels. All combinations of color sub-pixels that can achieve the effect of mixing into white light should be included in the scope of protection of the present invention. When using other When using sub-pixels of different colors, the same effect can be achieved by selecting dichroic dyes corresponding to the colors of the sub-pixels.
PDLC层是由丙烯酸酯类高分子基体26、向列相液晶27和二向性染料28组成，第一透射子像素和第一反射子像素为红色子像素时，第一聚合物分散液晶包括丙烯酸酯类高分子基体、向列相液晶和红色二向性染料；第二透射子像素和第二反射子像素为绿色子像素时，第二聚合物分散液晶包括丙烯酸酯类高分子基体、向列相液晶和绿色二向性染料；第三透射子像素和第三反射子像素为蓝色子像素时，第三聚合物分散液晶包括丙烯酸酯类高分子基体、向列相液晶和蓝色二向性染料。The PDLC layer is composed of an acrylic polymer matrix 26, a nematic liquid crystal 27, and a dichroic dye 28. When the first transmissive sub-pixel and the first reflective sub-pixel are red sub-pixels, the first polymer dispersed liquid crystal includes acrylic an ester polymer matrix, a nematic liquid crystal, and a red dichroic dye; when the second transmission sub-pixel and the second reflection sub-pixel are green sub-pixels, the second polymer-dispersed liquid crystal includes an acrylic polymer matrix, a nematic phase liquid crystal and green dichroic dye; when the third transmission sub-pixel and the third reflection sub-pixel are blue sub-pixels, the third polymer dispersed liquid crystal includes acrylate polymer matrix, nematic liquid crystal and blue dichroic dye sexual dyes.
进一步地，如图2所示，反射区域32包含三个反射子像素254、255和256，第一基板上的反射区域32依次设置有透明电极24和反射层29，反射层29上设置有对应每一子像素区域的薄膜场效应晶体管(ThinFilmTransistor，TFT)30；透射区域33也包含三个透射子像素251、252和253，第一基板22上的透射区域33设置有透明电极24，透明电极24上设置有对应每一子像素区域的薄膜场效应晶体管30。这样每一个子像素内的聚合物分散液晶层对应一个独立的薄膜场效应晶体管，聚合物分散液晶层的透过率随着电压的增大而增大，由于各个子像素区域的聚合物分散液晶层是独立驱动，这样通过调节施加电压的大小可以调节聚合物分散液晶层的透过率，因此可通过调节施加电压的大小以调节在反射区域显示的彩色平衡，而提高反射区域的亮度，从而实现在透射区域与反射区域显示的彩色平衡。Further, as shown in FIG. 2 , the reflective region 32 includes three reflective sub-pixels 254, 255 and 256. The reflective region 32 on the first substrate is sequentially provided with a transparent electrode 24 and a reflective layer 29, and the reflective layer 29 is provided with corresponding A thin film field effect transistor (ThinFilmTransistor, TFT) 30 in each sub-pixel area; the transmission area 33 also includes three transmission sub-pixels 251, 252 and 253, the transmission area 33 on the first substrate 22 is provided with a transparent electrode 24, and the transparent electrode 24 is provided with a thin film field effect transistor 30 corresponding to each sub-pixel area. In this way, the polymer-dispersed liquid crystal layer in each sub-pixel corresponds to an independent thin film field-effect transistor, and the transmittance of the polymer-dispersed liquid crystal layer increases with the increase of voltage, because the polymer-dispersed liquid crystal in each sub-pixel area The layers are driven independently, so that the transmittance of the polymer-dispersed liquid crystal layer can be adjusted by adjusting the applied voltage, so the brightness of the reflective area can be improved by adjusting the applied voltage to adjust the color balance displayed in the reflective area. Achieve color balance between transmissive and reflective areas.
本实施例中，PDLC层是由丙烯酸酯类高分子基体26、向列相液晶27和二向性染料28组成，其中，二向性染料28包括有红色、蓝色和绿色，相应地，分别形成红色PDLC层、蓝色PDLC层和绿色PDLC层。本实施例中，反射区域和透射区域可以按如图2所示的方式来设置，即在一个像素内，三个透射子像素相邻设置，三个反射子像素相邻设置，也可按照一个透射子像素和一个反射子像素相邻设置，即透射区域和反射区域以子像素为单位间隔设置。In this embodiment, the PDLC layer is composed of an acrylate polymer matrix 26, a nematic liquid crystal 27 and a dichroic dye 28, wherein the dichroic dye 28 includes red, blue and green, correspondingly, respectively A red PDLC layer, a blue PDLC layer, and a green PDLC layer are formed. In this embodiment, the reflective area and the transmissive area can be set as shown in Figure 2, that is, in one pixel, three transmissive sub-pixels are adjacently arranged, and three reflective sub-pixels are adjacently arranged, or one The transmission sub-pixel and one reflection sub-pixel are arranged adjacent to each other, that is, the transmission area and the reflection area are arranged at intervals of sub-pixels.
PDLC的光学特性很大程度上依赖于液晶分子的有效折射率，也就是说，通过对液晶分子的选择，可以调节PDLC的透射光、反射光与折射光的程度。因此，对于彩色PDLC层，可以根据需要的透射、反射和折射条件，采用具有合适有效折射率的液晶分子，以实现良好的透过率和反射率。本发明实施例中，采用含有红色、蓝色、绿色的二向性染料的3种彩色PDLC层，各个PDLC层利用不同的TFT来独立驱动。在没有施加电压的时候，PDLC层分别显示红色、蓝色和绿色。当施加饱和电压时液晶微滴随着电场的方向排列，而每个PDLC层都显示透明态。在施加电压少于饱和电压的时候，PDLC层的透过率是随着电压的增大而增大，也就是说通过调节施加电压的大小可以调节PDLC层的透过率；由于各个PDLC层是独立驱动，调节各个TFT的施加电压状态可以显示出任何颜色，因此可以省去液晶显示面板上设置的彩膜，提高光线的透过率。当未施加电压时，在透射区域背光源发射的光线在彩色PDLC层折射而透过，显示暗态，在反射区域外光在彩色PDLC层上发生反射而显示暗态。在施加电压时，在透射区域和反射区域的PDLC层入射光不发生折射和反射而直接透射出来，所以显示透明态，两区域都显示亮态。The optical properties of PDLC largely depend on the effective refractive index of liquid crystal molecules, that is, through the selection of liquid crystal molecules, the degree of transmitted light, reflected light and refracted light of PDLC can be adjusted. Therefore, for the color PDLC layer, liquid crystal molecules with a suitable effective refractive index can be used according to the required transmission, reflection and refraction conditions to achieve good transmittance and reflectance. In the embodiment of the present invention, three kinds of color PDLC layers containing red, blue, and green dichroic dyes are used, and each PDLC layer is independently driven by different TFTs. When no voltage is applied, the PDLC layers display red, blue and green, respectively. When the saturation voltage is applied, the liquid crystal droplets align with the direction of the electric field, and each PDLC layer shows a transparent state. When the applied voltage is less than the saturation voltage, the transmittance of the PDLC layer increases with the increase of the voltage, that is to say, the transmittance of the PDLC layer can be adjusted by adjusting the applied voltage; since each PDLC layer is Independently driven, any color can be displayed by adjusting the applied voltage state of each TFT, so the color film set on the liquid crystal display panel can be omitted, and the transmittance of light can be improved. When no voltage is applied, the light emitted by the backlight in the transmissive area is refracted and transmitted through the colored PDLC layer, showing a dark state, and outside the reflective area, the light is reflected on the colored PDLC layer to display a dark state. When a voltage is applied, the incident light of the PDLC layer in the transmissive area and the reflective area is directly transmitted without refraction and reflection, so it shows a transparent state, and both areas show a bright state.
另外在没有施加电压时，由于入射光在透射区域折射而透过，入射光在反射区域经反射再透过，因此反射区域的光线的光程大于透射区域的光线的光程，如果透射区域的彩色PDLC层和反射区域的彩色PDLC层的折射率相等，这样将造成透射区域与反射区域显示的不平衡。因此在本实施例中，透射区域的彩色PDLC层与反射区域的彩色PDLC层的反射率可以是不同的，反射区域的PDLC的折射率小于透射区域的PDLC的折射率，这样在没有施加电压时，透射区域具有较高的透过率和良好亮度的彩色显示，同时反射区域有很好的反射率而实现良好的彩色显示，从而实现透射区域与反射区域显示的平衡。In addition, when no voltage is applied, since the incident light is refracted and transmitted in the transmissive area, and the incident light is reflected and transmitted in the reflective area, the optical path of the light in the reflective area is longer than the optical path of the light in the transmissive area. The refractive index of the colored PDLC layer in the reflective area and the colored PDLC layer in the reflective area are equal, which will cause an unbalanced display between the transmissive area and the reflective area. Therefore, in this embodiment, the reflectivity of the colored PDLC layer in the transmissive area and the colored PDLC layer in the reflective area can be different, and the refractive index of the PDLC in the reflective area is smaller than that of the PDLC in the transmissive area, so that when no voltage is applied The transmissive area has high transmittance and good brightness color display, while the reflective area has good reflectivity to achieve good color display, so as to achieve a balance between the transmissive area and the reflective area.

本实施例中，PDLC层是由丙烯酸酯类高分子基体26、向列相液晶27和二向性染料28组成，其中，二向性染料28包括有红色、蓝色和绿色，相应地，分别形成红色PDLC、蓝色PDLC和绿色PDLC。如图2和图3所示，每一个像素单元包括第一透射红色子像素251、第二透射子像素252、第三透射子像素253、第一反射子像素254、第二反射子像素255和第三反射子像素256。本实施例中，反射子像素和透射子像素可以按如图2所示的方式来设置，即在一个像素内，三个透射子像素相邻设置，三个反射子像素相邻设置，也可按照一个透射子像素和一个反射子像素相邻设置，即透射区域和反射区域以子像素为单位间隔设置。In this embodiment, the PDLC layer is composed of an acrylate polymer matrix 26, a nematic liquid crystal 27 and a dichroic dye 28, wherein the dichroic dye 28 includes red, blue and green, correspondingly, respectively Red PDLC, blue PDLC and green PDLC are formed. As shown in FIG. 2 and FIG. 3 , each pixel unit includes a first transmissive red sub-pixel 251, a second transmissive sub-pixel 252, a third transmissive sub-pixel 253, a first reflective sub-pixel 254, a second reflective sub-pixel 255 and The third reflective sub-pixel 256 . In this embodiment, the reflective sub-pixels and the transmissive sub-pixels can be arranged as shown in FIG. One transmissive sub-pixel and one reflective sub-pixel are adjacently arranged, that is, the transmissive area and the reflective area are arranged at intervals of sub-pixels.
PDLC的光学特性很大程度上依赖于液晶分子的折射率，也就是说，通过对液晶分子的选择，可以调节PDLC的透射光、反射光与折射光的程度。因此，对于彩色PDLC层，可以根据需要的透射、反射和折射条件，采用具有合适有效折射率的液晶分子，以实现良好的透过率和反射率。本发明实施例中，采用含有红色、蓝色、绿色的二向性染料的3种彩色PDLC层，各个PDLC层利用不同的TFT来独立驱动。在没有施加电压的时候，PDLC层分别显示红色、蓝色和绿色。当施加饱和电压时液晶微滴随着电场的方向排列，而每个PDLC层都显示透明态。在施加电压少于饱和电压的时候，PDLC层的透过率是随着电压的增大而增大，也就是说通过调节施加电压的大小可以调节PDLC层的透过率；由于各个PDLC层是独立驱动，调节各个TFT的施加电压状态可以显示出任何颜色，因此可以省去液晶显示面板上设置的彩膜，提高光线的透过率。当未施加电压时，在透射区域背光源发射的光线在彩色PDLC层折射而透过，显示暗态，在反射区域外光在彩色PDLC层上发生反射而显示暗态。在施加电压时，在透射区域和反射区域的PDLC层入射光不发生折射和反射而直接透射出来，所以显示透明态，两区域都显示亮态。The optical characteristics of PDLC largely depend on the refractive index of liquid crystal molecules, that is to say, the degree of transmitted light, reflected light and refracted light of PDLC can be adjusted by selecting liquid crystal molecules. Therefore, for the color PDLC layer, liquid crystal molecules with a suitable effective refractive index can be used according to the required transmission, reflection and refraction conditions to achieve good transmittance and reflectance. In the embodiment of the present invention, three kinds of color PDLC layers containing red, blue, and green dichroic dyes are used, and each PDLC layer is independently driven by different TFTs. When no voltage is applied, the PDLC layers display red, blue and green, respectively. When the saturation voltage is applied, the liquid crystal droplets align with the direction of the electric field, and each PDLC layer shows a transparent state. When the applied voltage is less than the saturation voltage, the transmittance of the PDLC layer increases with the increase of the voltage, that is to say, the transmittance of the PDLC layer can be adjusted by adjusting the applied voltage; since each PDLC layer is Independently driven, any color can be displayed by adjusting the applied voltage state of each TFT, so the color film set on the liquid crystal display panel can be omitted, and the transmittance of light can be improved. When no voltage is applied, the light emitted by the backlight in the transmissive area is refracted and transmitted through the colored PDLC layer, showing a dark state, and outside the reflective area, the light is reflected on the colored PDLC layer to display a dark state. When a voltage is applied, the incident light of the PDLC layer in the transmissive area and the reflective area is directly transmitted without refraction and reflection, so it shows a transparent state, and both areas show a bright state.
另外在没有施加电压时，由于入射光在透射区域折射而透过，入射光在反射区域经反射再透过，因此反射区域的光线的光程大于透射区域的光线的光程，如果透射区域的彩色PDLC层和反射区域的彩色PDLC层的折射率相等，这样将造成透射区域与反射区域显示的不平衡。因此在本实施例中，透射区域的彩色PDLC层与反射区域的彩色PDLC层的反射率是不同的，反射区域的PDLC的折射率小于透射区域的PDLC的折射率，这样在没有施加电压时，透射区域具有较高的透过率和良好亮度的彩色显示，同时反射区域有很好的反射率而实现良好的彩色显示，从而实现透射区域与反射区域显示的平衡。具体地，反射区域的PDLC可以采用有效折射率为0.16的向列相液晶，而在透射区域的PDLC可以采用有效折射率为0.20的向列相液晶。In addition, when no voltage is applied, since the incident light is refracted and transmitted in the transmissive area, and the incident light is reflected and transmitted in the reflective area, the optical path of the light in the reflective area is longer than the optical path of the light in the transmissive area. The refractive index of the colored PDLC layer in the reflective area and the colored PDLC layer in the reflective area are equal, which will cause an unbalanced display between the transmissive area and the reflective area. Therefore, in this embodiment, the reflectivity of the colored PDLC layer in the transmissive area is different from that in the reflective area, and the refractive index of the PDLC in the reflective area is smaller than that of the PDLC in the transmissive area, so that when no voltage is applied, The transmissive area has high transmittance and good brightness for color display, while the reflective area has good reflectivity to achieve good color display, thereby achieving a balance between the transmissive area and the reflective area. Specifically, the PDLC in the reflective region may use a nematic liquid crystal with an effective refractive index of 0.16, while the PDLC in the transmissive region may use a nematic liquid crystal with an effective refractive index of 0.20.
