Description

一种显示面板及其制作方法、显示装置 技术领域
本申请涉及显示领域，特别涉及一种显示面板及其制作方法、显示装置。
 背景技术
在显示面板中加入偏光片能够降低强光下显示面板对外界光线的反射率，但是也存在以下缺陷。一方面，偏光片会减少OLED显示面板中有机发光材料的使用寿命；另一个方面，偏光片厚度较大、材质脆，不利于动态弯折显示面板的开发。为了开发基于OLED显示技术的动态弯折产品，必须导入新材料、新技术以及新工艺代替偏光片。
在显示面板中，采用彩膜层替代偏光片的方式能够解决上述问题。使用彩膜技术的显示面板不仅能够实现显示面板的轻薄化，而且能够将显示面板的出光率从42%提高至60%，提高了显示面板的对比度。但是，使用彩膜技术的显示面板的反射率较高，不利于室外显示。
因此，目前亟需一种显示面板及其制作方法以解决上述问题。

本申请提供了一种显示面板及其制作方法，以解决显示面板对外界环境光反射率较高的问题。
请参阅图1，图1为本申请第一实施例提供的显示面板10的结构示意图。
根据本申请的一个方面，提供了一种显示面板10，包括基板11以及设置于所述基板11上方的彩膜层12。
在一种实施例中，所述基板11包括阵列基板，所述阵列基板包括基底以及设置在所述基底上的薄膜晶体管阵列，所述薄膜晶体管阵列用于控制所述显示面板10中像素的显示。
其中，所述显示面板10包括像素开口区10a以及设置于所述像素开口区10a周围的非开口区10b。
显示面板10包括显示区以及围绕所述显示区设置的非显示区，所述显示区内设置有多个用于实现显示面板10显示功能的像素，相邻所述像素之间存在空隙；
其中，所述像素所对应的区域为像素开口区10a，所述像素之间的空隙所对应的区域为非开口区10b。
在一种实施例中，所述彩膜层12包括对应于所述像素开口区10a的第一色阻单元121以及对应于所述非开口区10b的第二色阻单元122。
所述第一色阻单元121用以将所述像素的出光过滤为预定色度的光；所述第二色阻单元122用以将所述像素之间的出光吸收，防止相邻像素之间发生漏光。
所述第二色阻单元122包括本体1221以及设置于所述本体1221表面用于降低光线反射率的纳米阵列结构1222。当外界光线照入所述显示面板10时，在所述纳米阵列结构1222处发生多次漫反射，进而增加了光线的吸收和消耗。本申请通过漫反射和吸收的协同作用降低了彩膜层12的反射率，进而提高了显示面板10的对比度。
在一种实施例中，所述本体1221和所述纳米阵列结构1222一体化设置。
每个所述像素至少包括红色子像素、绿色子像素和蓝色子像素。
在一种实施例中，所述第一色阻单元121至少包括红色色阻单元、绿色色阻单元和蓝色色阻单元，所述第二色阻单元122包括黑色色阻单元。
所述红色色阻单元对应于所述红色子像素，所述绿色色阻单元对应于所述绿色子像素，所述蓝色色阻单元对应于所述蓝色子像素。
其中，所述红色色阻单元、所述绿色色阻单元和所述蓝色色阻单元中的任意两者通过所述黑色色阻单元隔离，以防止相邻所述像素之间发生漏光。
在一种实施例中，所述第一色阻单元121和所述第二色阻单元122的制备材料包括光刻胶。
纳米压印技术（Nano Imprint Lithography，简称NIL）是通过光刻胶辅助，将模板上的微纳结构转移到待加工材料上的技术。
其通常包括以下三个步骤：
1、模板的技工；
2、图样的转移；
3、衬底的加工。
在一种实施例中，所述纳米阵列结构1222通过纳米压印技术形成于所述本体1221表面，通过采用纳米压印技术能够实现纳米阵列结构1222的微纳结构。
纳米压印技术突破了传统光刻胶在特征尺寸减少过程中的难题，具有分辨率高、低成本和高产率的特点。
粗糙的表面容易发生漫反射而显得黯淡无光，本申请通过纳米阵列结构1222的设置能够提升第二色阻单元122的粗糙度。
为了提升所述纳米阵列结构1222对光线的吸收和反射，需将纳米阵列结构1222设计为易于光线反射的形状和结构。例如，所述纳米阵列结构1222包括圆锥状纳米阵列结构。
请参阅图4，图4为本申请第四实施例提供的圆锥状纳米结构1222a的示意图。
圆锥状纳米阵列结构1222a也称为金字塔状纳米阵列结构。
请参阅图5，图5为本申请第五实施例提供的纳米阵列结构1222对光线反射的示意图。
在一种实施例中，圆锥状纳米阵列结构1222a包括阵列排布的圆锥状纳米结构1222a。所述圆锥状纳米结构1222a从侧面看可以简化为等腰三角形。通过计算等腰三角形的高H与底面积S之比，可以得到其比值系数ρ。当ρ值越大，等腰三角形越细，那么光照射到表面的反射次数越多，反射率也越低。ρ值越小，纳米结构的制备也越困难。因此，必须综合技术成本以及技术效果，进行ρ值的优化。
在一种实施例中，所述纳米阵列结构1222的形状并不仅限于圆锥状，也可以为半圆体状等其它能够增加对光的漫反射和吸收的形状。
在一种实施例中，所述彩膜层12结构可应用于液晶显示面板和有机发光显示面板中的其中一者，均能够改善相对应的显示面板10的开口率。
