 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例提供了一种显示屏，该显示屏包括框架、盖板1和显示模组，盖板1和显示模组层叠设置在框架上，显示模组包括发光单元，盖板1的表面具有通过蚀刻形成的、用于将发光单元发出的光线打散的防眩光层和/或显示模组包括用于将发光单元发出的光线打散的均光结构。其中，防眩光层简称AG（Anti-Glare）层。
具体的，在盖板1表面蚀刻形成凹凸不平的防眩光层，凹凸不平的防眩光层可使发光单元的光线多角度漫反射，因此通过设置防眩光层可以将发光单元发出的光线打散变均匀，从而光线入眼舒适，达到护眼的效果；通过显示模组的均光结构可以将发光单元发出的光线打散，使得发光单元发出的光线均匀，从而光线入眼舒适，达到护眼的效果。
如图1所示，在本申请的一些实施例中，发光单元为LED2（Light-Emitting Diode，发光二极管），显示模组还包括柔性屏3、三个扩散片4、导光板5和反射片6，盖板1、柔性屏3、三个扩散片4、导光板5和反射片6依次层叠设置在框架上，LED2设置在导光板5的一侧；盖板1的表面具有通过蚀刻形成的、用于将发光单元发出的光线打散的防眩光层，和/或柔性屏3的表面具有通过蚀刻形成的防眩光层，柔性屏3表面的防眩光层构成均光结构。应当理解的是，柔性屏3表面蚀刻形成的凹凸不平的防眩光层同样可使发光单元的光线多角度漫反射，从而将发光单元发出的光线打散变均匀，使得光线入眼舒适，达到护眼的效果。
可选的，可以只在盖板1表面设置通过蚀刻形成的防眩光层，或者只在柔性屏3的表面设置通过蚀刻形成的防眩光层，或者是在盖板1的表面和柔性屏3的表面同时设置通过蚀刻形成的防眩光层。当只在柔性屏3的表面设置通过蚀刻形成的防眩光层时，盖板1为普通盖板；当盖板1的表面和柔性屏3的表面同时设置有通过蚀刻形成的防眩光层时，可以使发光单元发出的光线打散得更均匀，光线入眼更舒适，护眼效果更佳。
可以理解的是，一种传统的显示模组包括LCD（Liquid Crystal Display，液晶显示器）、扩散片、导光板、反射片和LED，本申请实施例中的显示模组将传统显示模组中的LCD更换为柔性屏3，柔性屏3可折叠且更薄更轻，因此减轻了显示屏的整体重量和厚度，使得显示屏更便于携带。
可选的，盖板1表面的防眩光层可以设置在盖板1朝向柔性屏3的一面，也可以设置在盖板1背离柔性屏3的一面，或者在盖板1朝向柔性屏3的一面和盖板1背离柔性屏3的一面同时设置防眩光层。同理，柔性屏3表面的防眩光层可以设置在柔性屏3朝向盖板1的一面，也可以设置在柔性屏3背离盖板1的一面，或者在柔性屏3朝向盖板1的一面和柔性屏3背离盖板1的一面同时设置防眩光层。优选的，防眩光层的厚度小于等于30μm，此厚度范围的防眩光层护眼效果最佳。
应当理解的是，在盖板1背离柔性屏3的一面蚀刻形成的防眩光层还能使环境光多角度漫反射，从而降低环境光的干扰，提高画面的可视角度，减少屏幕反光，使用户拥有更佳的视觉享受。
可选的，当盖板1的表面和/或柔性屏3的表面具有通过蚀刻形成的、用于将发光单元发出的光线打散的防眩光层时，防眩光层上还设有抗反射增透层，抗反射增透层简称AR（Anti-Reflection）层，抗反射增透层可以提高透光率和降低反射率，从而减少屏幕反光，使显示屏的护眼效果更佳。优选的，抗反射增透层的厚度为150nm～380nm，此厚度范围的抗反射增透层护眼效果最佳。
如图2所示，在本申请的一些实施例中，发光单元为OLED7（Organic Light-Emitting Diode，有机发光器件），盖板1和OLED7层叠设置在框架上；盖板1的表面具有通过蚀刻形成的、用于将发光单元发出的光线打散的防眩光层，和/或OLED7的表面具有通过蚀刻形成的防眩光层，OLED7表面的防眩光层构成均光结构。应当理解的是，OLED7表面蚀刻形成的凹凸不平的防眩光层同样可使发光单元的光线多角度漫反射，从而将发光单元发出的光线打散变均匀，使得光线入眼舒适，达到护眼的效果。
可以理解的是，由于OLED7自带发光体，因此显示屏无需增加传统显示模组中的LCD、扩散片、导光板、反射片和LED等，减轻了显示屏的整体重量和厚度，使得显示屏更便于携带，而且OLED7的亮度更高，因此显示效果更好。
可选的，可以只在盖板1表面设置通过蚀刻形成的防眩光层，或者只在OLED7的表面设置通过蚀刻形成的防眩光层，或者是在盖板1的表面和OLED7的表面同时设置通过蚀刻形成的防眩光层。当只在OLED7的表面设置通过蚀刻形成的防眩光层，盖板1为普通的盖板；当盖板1的表面和OLED7的表面同时设置有通过蚀刻形成的防眩光层时，可以使发光单元发出的光线打散得更均匀，光线入眼更舒适，护眼效果更佳。
具体的，盖板1表面的防眩光层可以设置在盖板1朝向OLED7的一面，也可以设置在盖板1背离OLED7的一面，或者在盖板1朝向OLED7的一面和盖板1背离OLED7的一面同时设置防眩光层；而OLED7表面的防眩光层优选设置在OLED7朝向盖板1的一面。优选的，防眩光层的厚度小于等于30μm，此厚度范围的防眩光层护眼效果最佳。
应当理解的是，在盖板1背离OLED7的一面蚀刻形成的防眩光层还能使环境光多角度漫反射，从而降低环境光的干扰，提高画面的可视角度，减少屏幕反光，使用户拥有更佳的视觉享受。
可选的，当盖板1的表面和/或OLED7的表面具有通过蚀刻形成的、用于将发光单元发出的光线打散的防眩光层时，防眩光层上还设有抗反射增透层，抗反射增透层可以提高透光率和降低反射率，从而减少屏幕反光，使显示屏的护眼效果更佳。优选的，抗反射增透层的厚度为150nm～380nm，此厚度范围的抗反射增透层护眼效果较佳。
如图3所示，在本申请的一些实施例中，发光单元为Mini-LED8，显示模组还包括LCD9、三个扩散片4和反射片6，盖板1、LCD9、三个扩散片4、Mini-LED8和反射片6层叠设置，Mini-LED8和三个扩散片4构成均光结构。Mini-LED8相较于传统LED发光更均匀，不会有传统LED灯光不均匀的问题，且功耗更低；Mini-LED8搭配三个扩散片4可以将光线打散得更均匀，光线入眼舒适，而且不会使亮度降低，可维持与传统模组相同的亮度甚至提升了亮度，解决了传统护眼方案的低亮度问题和低亮度导致显示屏不能在户外使用的问题，让用户可以在户外使用显示屏。
可以理解的是，另一种传统的显示模组包括上增光片、下增光片、扩散片、导光板、反射片和LED，本申请实施例中的显示模组采用三个扩散片4的结构替代了传统显示模组中的上增光片、下增光片、扩散片和导光板，因此减轻了显示屏的整体重量和厚度，使得显示屏更便于携带。优选的，三个扩散片4的透光率均为80%～90%，采用高透光率的扩散片4能将光线打散得更均匀，从而光线入眼更舒适，护眼效果更佳。
可选的，盖板1的表面具有通过蚀刻形成的、用于将发光单元发出的光线打散的防眩光层。也就是说，在本申请的实施例中，可以选用普通的盖板1，也可以选用表面具有通过蚀刻形成的防眩光层的盖板1。优选的，防眩光层的厚度小于等于30μm，此厚度范围的防眩光层护眼效果最佳。
可选的，盖板1表面的防眩光层可以设置在盖板1朝向LCD9的一面，也可以设置在盖板1背离LCD9的一面。应当理解的是，在盖板1背离LCD9的一面上蚀刻形成的防眩光层还能使环境光多角度漫反射，从而降低环境光的干扰，提高画面的可视角度，减少屏幕反光，使用户拥有更佳的视觉享受。
可选的，当盖板1的表面具有通过蚀刻形成的、用于将发光单元发出的光线打散的防眩光层时，防眩光层上还设有抗反射增透层。抗反射增透层可以提高透光率和降低反射率，从而减少屏幕反光，使显示屏的护眼效果更佳。优选的，抗反射增透层的厚度为150nm～380nm，此厚度范围的抗反射增透层护眼效果最佳。
本申请实施例还提供了一种电子设备，该电子设备包括上述任一实施例所述的显示屏。电子设备可以是但不限于是平板电脑、手机、笔记本电脑、电视或电子书阅读器等。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
在本申请的描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个特征。
以上对本申请实施例所提供的显示屏和电子设备进行了详细介绍，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，本说明书内容不应理解为对本申请的限制。
