OLED显示装置相对于LCD显示装置的优点在于全固态显示下弯曲和折叠能力的显著提高。为进一步提高OLED显示面板的产品性能，现有技术利用COE技术(CF onEncapsulation)，在顶发射OLED器件的封装层(TFE)上通过光刻工艺形成图案化的彩膜层(CF)，该结构无需偏光片(POL)，能够有效提高显示亮度、降低整体厚度、以及提高显示色域。The advantage of an OLED display device over an LCD display device lies in the significantly improved bending and folding capabilities of an all-solid-state display. In order to further improve the product performance of the OLED display panel, the existing technology utilizes the COE technology (CF on Encapsulation) to form a patterned color filter layer (CF) on the encapsulation layer (TFE) of the top-emitting OLED device through a photolithography process. No polarizer (POL) is needed, which can effectively improve the display brightness, reduce the overall thickness, and increase the display color gamut.
然而，如图1a所示，COE结构的显示面板处于暗态时，其在外部光源的照射下屏幕出现明显的色分离现象。现有技术中，通过在涂覆胶OC中掺杂散射粒子以改善该问题，该方案形成的色分离现象如图1b所示，由图1b可知，其色分离的现象有轻度改善。However, as shown in FIG. 1a, when the display panel with the COE structure is in a dark state, the screen has obvious color separation phenomenon under the illumination of an external light source. In the prior art, this problem is improved by doping scattering particles in the coating glue OC. The color separation phenomenon formed by this solution is shown in FIG. 1b. It can be seen from FIG. 1b that the color separation phenomenon has been slightly improved.
因此，本发明实施例提出一种显示基板、显示面板及显示装置，以解决上述问题。Therefore, embodiments of the present invention provide a display substrate, a display panel, and a display device to solve the above problems.
如图1a所示，第一方向为图X方向，第二方向为图示Y方向。由图1a中现有显示面板的色分离图像可知，人眼能够观察到的色分离现象具体为：在Y方向显示为绿色光线11’，在X方向显示为粉红色光线12’。As shown in Fig. 1a, the first direction is the X direction in the figure, and the second direction is the Y direction in the figure. From the color separation image of the existing display panel in Fig. 1a, it can be seen that the color separation phenomenon that can be observed by the human eye is specifically: green light 11' in the Y direction, and pink light 12' in the X direction.
进一步的，发明人根据如图2所示的马蹄形色域图发现，马蹄形色域图中，偏绿的色块沿Y方向上形成绿色区域，偏粉色的色块沿X方向上形成粉色区域，该色域图的色域分配与现有技术中显示面板于暗态下的出现的色分离现象一致。进一步的，绿色区域与粉红色区域中间处即为白色区域。Further, the inventor found that according to the horseshoe-shaped color gamut diagram shown in Figure 2, in the horseshoe-shaped color gamut diagram, the greenish color blocks form a green area along the Y direction, and the pinkish color blocks form a pink area along the X direction. The color gamut distribution of the color gamut diagram is consistent with the color separation phenomenon in the dark state of the display panel in the prior art. Further, the middle of the green area and the pink area is the white area.

There is a problem of color separation under illumination, the dark state display effect of the display panel can be effectively improved, and the invention has wide application prospects.
在一个可选的实施例中，所述阵列排布的像素单元沿预设方向排列。在一个可选的实施例中，所述预设方向包括第一方向和/或第二方向。如图3所示，预设方向即为第一方向X、第二方向Y、或者第一方向X和第二方向Y，像素单元(包括第一像素单元的一个第一子像素单元1和第二像素单元的一个第二子像素单元2)作为一个整体在第一方向X、第二方向Y、或者第一方向和第二方向上阵列排布。In an optional embodiment, the pixel units arranged in an array are arranged along a preset direction. In an optional embodiment, the preset direction includes a first direction and/or a second direction. As shown in FIG. 3, the preset direction is the first direction X, the second direction Y, or the first direction X and the second direction Y, and the pixel unit (including a
在本实施例中，基于本发明实施例的排布方式，在所述显示基板为暗态时，所述第一子像素单元能够响应于环境光反射第一光线；所述第二子像素单元能够在所述显示基板为暗态时响应于所述环境光反射第二光线，所述第一光线在第一方向和第二方向上呈现的颜色分别和所述第二光线在第一方向和第二方向上呈现的颜色形成白平衡，以解决现有技术中显示面板处于暗态时在环境光照射下存在色分离的问题，有效提高显示面板的暗态显示效果，具有广泛的应用前景。In this embodiment, based on the arrangement of the embodiment of the present invention, when the display substrate is in a dark state, the first sub-pixel unit can reflect the first light in response to ambient light; the second sub-pixel unit The second light can be reflected in response to the ambient light when the display substrate is in a dark state, and the colors presented by the first light in the first direction and the second direction are respectively different from those of the second light in the first direction and the second direction. The colors presented in the second direction form a white balance to solve the problem of color separation under ambient light irradiation in the prior art when the display panel is in the dark state, effectively improve the display effect of the display panel in the dark state, and have broad application prospects.
在一个可选的实施例中，如图3所示，第一红色子像素11的延伸方向Y’与第二红色子像素21的延伸方向X’正交；In an optional embodiment, as shown in FIG. 3 , the extending direction Y' of the first
第一绿色子像素12的延伸方向Y’与第二绿色子像素22的延伸方向X’正交；The extension direction Y' of the first
第一蓝色子像素13的延伸方向Y’与第二蓝色子像素23的延伸方向X’正交。The extending direction Y' of the first
如图3所示，第一子像素单元中的第一红色子像素11、第一绿色子像素12以及第一蓝色子像素13的延伸方向为图示Y’方向；第二像素单元中的第二红色子像素21、第二绿色子像素22以及第二蓝色子像素23的延伸方向为图示X’方向。由图3可知，第一红色子像素11的延伸方向垂直于第二红色子像素21的延伸方向，第一绿色子像素12的延伸方向垂直于第二绿色子像素22的延伸方向，第一蓝色子像素13的延伸方向垂直于第二蓝色子像素23的延伸方向。As shown in Figure 3, the extension direction of the first
该排布结构下，显示面板处于点亮状态时，第一像素单元通过第一红色子像素、第一绿色子像素以及第一蓝色子像素发射显示光线，第二像素单元通过第二红色子像素、第二绿色子像素以及第二蓝色子像素发射显示光线。显示面板处于暗态时，第一像素单元响应于环境光反射第一光线，第二像素单元响应于环境光反射第二光线，第一光线和第二光线分别在第一方向和第二方向均形成白平衡，从而有效改善现有技术中显示面板出现的色分离问题。Under this arrangement structure, when the display panel is in the lighted state, the first pixel unit emits display light through the first red sub-pixel, the first green sub-pixel and the first blue sub-pixel, and the second pixel unit emits display light through the second red sub-pixel. The pixel, the second green sub-pixel and the second blue sub-pixel emit display light. When the display panel is in the dark state, the first pixel unit reflects the first light in response to the ambient light, and the second pixel unit reflects the second light in response to the ambient light, and the first light and the second light travel in the first direction and the second direction respectively. A white balance is formed, thereby effectively improving the color separation problem of the display panel in the prior art.
该排布结构下，显示基板处于暗态时，第一像素单元响应于环境光反射第一光线，该第一光线在人眼中显示为沿Y方向为绿色，沿X方向为粉色。第二像素单元响应于环境光反射第二光线，该第二光线在人眼中显示为沿Y方向为粉色，沿X方向为绿色。Under this arrangement structure, when the display substrate is in a dark state, the first pixel unit reflects the first light in response to ambient light, and the first light is displayed as green along the Y direction and pink along the X direction to human eyes. The second pixel unit reflects the second light in response to the ambient light, and the second light is displayed as pink along the Y direction and green along the X direction to human eyes.
在一个具体实例中，基于图2的马蹄形色域图可知，绿色光线和粉色光线的中心点是白色，因此，结合现有技术中的色分离现象，在第一方向上，第一光线的粉色和第二光线的绿色能够实现白平衡，在第二方向上，第一光线的绿色和第二光线的粉色能够实现白平衡，因此，基于该排布结构，本发明实施例利用第一光线在两个方向上显示的不同颜色，以及利用第二光线在两个方向上显示的不同颜色，根据色域图中绿色和粉色的色域分配，使得第二方向上第一颜色和第二颜色实现平衡，第二方向和第一方向上的第一光线和第二光线均能够实现白平衡，从而有效改善显示装置处于暗态下存在的色分离问题。In a specific example, based on the horseshoe-shaped color gamut diagram in FIG. 2, it can be known that the central points of the green light and the pink light are white. Therefore, in combination with the color separation phenomenon in the prior art, in the first direction, the pink color of the first light and the green color of the second light can achieve white balance. In the second direction, the green color of the first light and the pink color of the second light can achieve white balance. Therefore, based on this arrangement structure, the embodiment of the present invention utilizes the first light in The different colors displayed in the two directions, and the different colors displayed in the two directions by the second light, according to the color gamut allocation of green and pink in the color gamut diagram, make the first color and the second color in the second direction realize Balance, the first light and the second light in the second direction and the first direction can both achieve white balance, thereby effectively improving the color separation problem that exists when the display device is in a dark state.

本发明实施例中，两个子像素单元中颜色鲜艳的红色子像素距离较近，在确保显示装置良好的熄屏效果时，还具有良好的显示效果。此状态下，在有效改善显示装置色分离问题的基础上，还能够实现更艳丽的显示效果。In the embodiment of the present invention, the brightly colored red sub-pixels in the two sub-pixel units are relatively close to each other, so that a good display effect can be achieved while ensuring a good screen-off effect of the display device. In this state, on the basis of effectively improving the color separation problem of the display device, a brighter display effect can also be achieved.
