Description

显示面板及显示装置 技术领域
本申请涉及显示技术领域，特别涉及一种显示面板及一种显示装置。
 背景技术
POL（Polarizer，偏光片）能够有效地降低外界强光下OLED（organic light emitting diode display，有机发光二极管显示）面板的反射率，却损失了接近58%的出光。这对于OLED面板来说，极大地增加了其寿命负担。
使用彩膜替代偏光片被归属为POL-less技术，它不仅能将功能层的厚度从100μm降低至5μm；而且能够将出光率从42%提高至60%。在OLED面板之中，R/G/B色阻分别对应R/G/B子像素单元的出光；而黑色矩阵则主要承担着防止面板的漏光与降低面板的反射的作用。现有技术中，R/G/B色阻一般相同，BM（Black Matrix，黑色矩阵）会挡住一部分子像素的光，尤其是在大视角情况下，会导致显示面板的光学特性较差。

在本申请的实施例提供的显示面板100中，将第一色阻块31的厚度设置为与第二色阻块32的厚度及第三色阻块33的厚度中的至少一个不同，使得第一色阻块31的透过率不同于第二色阻块32的透过率及第三色阻块33的透过率中的至少一个，突破了将第一色阻块31、第二色阻块32和第三色阻块33的透过率设置为相同的传统设计，改善透过率相同的光容易在黑色矩阵35处发生衍射相互干扰的现象，能够平衡显示面板100的大视角特性、息屏色相及色分离特性，改善显示面板100的光学特性。
在一些实施例中，所述第一色阻块31的厚度、所述第二色阻块32的厚度和所述第三色阻块33的厚度均位于2-4μm的范围内，从而可以将所述第一色阻块31、所述第二色阻块32和所述第三色阻块33的透过率控制在50%-65%的范围内。进一步地，所述第一色阻块31的厚度、所述第二色阻块32的厚度和所述第三色阻块33的厚度按照从大到小的顺序排列后，相邻两者之间的差值不超过1μm，使得所述第一色阻块31、所述第二色阻块32和所述第三色阻块33的透过率之间的变化不会过大，可以使得所述显示面板100具有更佳的显示效果。
在一些实施例中，所述第一色阻块31包括红色光阻材料，厚度为3.5μm，透过率为56%。所述第二色阻块32包括绿色光阻材料，厚度为3μm，透过率在59%-60%之间。所述第三色阻块33包括蓝色光阻材料，厚度为3.5μm，透过率在59%-60%之间，如图4b所示，在改善后的显示面板100发出的光中，人眼看不到外围红光。图4a为现有技术中将色阻块的透过率设置为相同的显示面板的光学效果图，可以明显看出外围红光R1，由此可以得出，本实施例的显示面板的外围红光被抑制，色分离现象得到改善。
请参阅图3和图5，在一些实施例中，为了防止相邻的子像素的光相互干扰，所述彩色滤光膜3包括黑色矩阵35，所述黑色矩阵35设有多个孔，所述第一色阻块31、所述第二色阻块32和所述第三色阻块33至少部分位于对应的孔内。所述第三色阻块33的面积大于所述第一色阻块31的面积，所述第一色阻块31的面积大于所述第二色阻块32的面积。其中，多个第二色阻块32沿行方向和列方向排列，每四个所述第二色阻块32的中心作为顶点围成虚拟矩形。每个所述第一色阻块31和每个所述第三色阻块33的中心位于对应的所述虚拟矩形的中心。在行方向和列方向上，所述第一色阻块31和所述第三色阻块33均间隔排列。
在一些实施例中，由于从色阻块的边缘射出的光容易在黑色矩阵35处产生衍射从而加剧色分离，因此，减少从色阻块的边缘射出的光的量，可改善色分离现象。具体地，请参阅图5，所述第一色阻块31的边缘的厚度大于所述第一色阻块31的中心的厚度，可减小所述第一色阻块31的边缘的光透过率。
在一些实施例中，由于从色阻块射出的光容易在黑色矩阵35处产生衍射从而加剧色分离，因此，减少从色阻块的射出的光的量，可改善色分离现象。具体地，请参阅图5，所述黑色矩阵35的靠近所述第一色阻块31的边缘的部分上设有第一吸收材料36或第一吸收材料37，以吸收或散射所述第一色阻块31和所述第一子发光单元21对应的颜色的光。散射材料可以包括亚克力颗粒或树脂颗粒。吸光材料可以包括树脂材料或金属氧化物材料如氧化钼、二氧化钛。
在一些实施例中，由于从色阻射出的光容易在黑色矩阵35处产生衍射从而加剧色分离，因此，使得尽可能多的光垂直地从色阻射出，可改善色分离现象。具体地，请参阅图5，所述显示面板100还包括透镜结构8，所述透镜结构8包括第一透镜、第二透镜和第三透镜，所述第一透镜位于所述第一色阻块31和所述第一子发光单元21之间，所述第二透镜位于所述第二色阻块32和所述第二子发光单元22之间，所述第三透镜位于所述第三色阻块33和所述第三子发光单元23之间；所述第一透镜的汇聚面朝向所述第一色阻块31，所述第二透镜的汇聚面朝向所述第二色阻块32，所述第三透镜的汇聚面朝向所述第一色阻块31。
请参阅图2，在一些实施例中，所述显示面板100还可以包括阵列基板5、封装层6和盖板7。
所述阵列基板5包括衬底51和位于所述衬底51上的TFT（Thin Film Transistor，薄膜晶体管）层52。所述TFT层52包括多个TFT，用于电性连接于所述阳极212，以控制所述第一子发光单元21、所述第二子发光单元22和所述第三子发光单元23的发光。在本实施例中，所述衬底51的材料可以是聚酰亚胺。
所述封装层6包括依次堆叠的第一无机层、有机层和第二无机层，所述第一无机层、所述有机层和所述第二无机层位于所述第一子发光单元21、第二子发光单元22和第三子发光单元23上，以实现对所述第一子发光单元21、第二子发光单元22和第三子发光单元23的封装。
所述盖板7通过光学胶70粘贴于所述彩色滤光膜3上，以实现对所述述彩色滤光膜3的保护。所述盖板7可以包括玻璃或柔性材料。
本申请的实施例还提供一种如上所述的彩色滤光膜3。
本申请的实施例还提供一种显示装置，包括如上所述的显示面板100。所述显示装置可以是固定终端如电视、台式电脑，移动终端如智能手机、平板电脑，也可以是可穿戴设备如智能手表、虚拟现实设备、增强现实设备。
本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
