 附图说明
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的一种显示面板结构示意图。
图2为本发明实施例提供的另一种显示面板结构示意图。
图3为本发明实施例提供的又一种显示面板结构示意图。
 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
本发明针对现有的显示面板及显示装置，由于激光笔照射于显示面板上将会发生镜面反射以及透射，导致激光笔的各个方向上的可视性效果较差，进而影响显示的技术问题，本实施例能够解决该缺陷。
本发明实施例提供一种显示面板，以解决上述缺陷，且所述显示面板包括：
阵列基板；
彩膜基板，设置于所述阵列基板上；
光致变色玻璃层，设置于所述彩膜基板上，且当紫外激光照射至所述光致变色玻璃层时产生一变色区域，以对经过所述变色区域的光线产生滤光作用；以及
散射粒子，分布于所述光致变色玻璃层上。
具体地，请参照图1所示，所述显示面板10包括阵列基板102，以及设置于所述阵列基板102上的彩膜基板，设置于所述阵列基板102以及所述彩膜基板之间的液晶层103。
其中，所述彩膜基板上设置有光致变色玻璃层101，则当紫外激光照射至所述光致变色玻璃层101时产生一变色区域，以对经过所述变色区域的光线产生滤光作用。
另外，所述光致变色玻璃层101背向所述阵列基板102的一侧分布设置有散射粒子104，以对经过的光线产生散射作用。
在实施应用过程中，由于现有液晶显示器表面反射率较高，激光笔在其表面主要为镜面反射和透射，导致激光笔的各个方向的可视性效果较差，在镜面反射的视角中，激光笔容易对用户造成眩光，而透射光线占所有光线中的90%以上，也会发生镜面反射，因此导致较差的用户体验，而本发明实施例提供的显示面板中，通过设置光致变色玻璃层，当激光笔的激光照射至显示面板上时将产生一变色区域，并对经过变色区域的光线产生滤光作用，再经过上层的散射粒子，形成大视角可见，解决镜面反射角度的眩光现象，增大了激光笔的大视角漫反射，实现了激光笔的大角度可视性。
更进一步地，所述光致变色玻璃层中设置有光致变色结构，且所述光致变色结构包括光致变色玻璃、光致变色偏光片、或光致变色薄膜，即所述光致变色结构可为上述任意一种变色结构设置亦或其他可行设置，以达到本发明实施例实现激光笔的大角度可视性的技术效果。

下面结合具体实施例对所述光致变色玻璃层的结构以作说明。
