 有益效果
相较于现有技术的显示面板，本申请的显示面板以及显示装置通过在像素电路单元外接入一个光敏晶体管，当光敏晶体管未吸收外界激光时，其不导通，显示区的垂直取向排列（Vertically aligned，VA）液晶电压正常，此时显示画面正常；当用户用激光笔照射本实施例的显示面板时，在激光笔照射的区域中，光敏晶体管吸收激光导通时，该区域显示区的连接有光敏晶体管的像素电路单元的电压被拉到公共电极的低准位，VA液晶没有压差，液晶不发生偏转，光线透不过液晶，该像素电路单元对应的画面为黑色，而在激光照射区域中的其他没有连接光敏晶体管的像素电路单元则正常显示颜色，这样使激光照射的区域显示非白色，能进行投影；解决了现有的液晶显示面板无法进行激光笔投影的技术问题。
 附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面对实施例中所需要使用的附图作简单的介绍。下面描述中的附图仅为本申请的部分实施例，对于本领域普通技术人员而言，在不付出创造性劳动的前提下，还可以根据这些附图获取其他的附图。
图1为本申请实施例的显示面板的阵列基板的部分电路结构示意图；
图2为本申请实施例的显示面板进行激光照射的效果图。
 本发明的实施方式
请参照附图中的图式，其中相同的组件符号代表相同的组件。以下的说明是基于所例示的本申请具体实施例，其不应被视为限制本申请未在此详述的其它具体实施例。
请参照图1，图1为本申请实施例的显示面板的阵列基板的部分电路结构示意图。图1中仅示出连接有光敏晶体管T2的单一个像素电路单元10的连接结构，但对于本实施例来说，并不限于此。
本实施例的显示面板100包括阵列基板，阵列基板包括栅线Gate、数据线Data、公共电极Com、多个像素电路单元10和光敏晶体管T2。
多个像素电路单元10电性连接于栅线Gate、数据线Data和公共电极Com。光敏晶体管T2电性连接于像素电路单元10和公共电极Com。
其中，当光敏晶体管T2接收外界光导通时，所述像素电路单元10的电压被拉低至所述公共电极Com的电压。
其中需要说明的是，本实施例的显示面板100包括阵列基板和彩膜基板，栅线Gate、数据线Data、低准位的公共电极Com、多个像素电路单元10、光敏晶体管T2设置在阵列基板上。彩膜基板包括与多个像素电路单元10一一对应的光阻，光阻包括红色光阻、绿色光阻和蓝色光阻等。
在本实施例中，在像素电路单元10外接入一个光敏晶体管T2，当光敏晶体管T2未吸收外界激光时，其不导通，显示区的垂直取向排列（Vertically aligned，VA）液晶电压正常，此时显示画面正常；当用户用激光笔照射本实施例的显示面板100时，在激光笔照射的区域中，光敏晶体管T2吸收激光导通时，该区域显示区的连接有光敏晶体管T2的像素电路单元10的电压被拉到公共电极Com的低准位，VA液晶没有压差，液晶不发生偏转，光线透不过液晶，该像素电路单元对应的画面不显示为黑色，而在激光照射区域中的其他没有连接光敏晶体管T2的像素电路单元10则正常显示颜色，这样使激光照射的区域显示非白色，能进行投影。
具体的，在本实施例的显示面板100中，每一个像素电路单元10包括薄膜晶体管T1、电容C、像素电极D和一节点E。
薄膜晶体管T1的栅极连接栅线Gate，薄膜晶体管T1的源极连接所述节点E，薄膜晶体管T1的漏极连接数据线Data。
电容C的一端连接节点E，电容C的另一端连接于公共电极Com。
像素电极D连接于节点E。
光敏晶体管T2的栅极和源极均连接于所述公共电极Com，光敏晶体管T2的漏极连接于节点E。
其中，栅线Gate、数据线Data、公共电极Com、像素电路单元10和光敏晶体管T2构成一光敏控制电路，用于拉低像素电路单元10的电压。
可选的，光敏晶体管T2为铟镓锌氧化物晶体管或硅晶体管。
进一步的，像素电极D包括分别对应于红色光阻、绿色光阻和蓝色光阻的红色像素电极、绿色像素电极和蓝色像素电极。
光敏晶体管T2一一连接于红色像素电极、绿色像素电极和蓝色像素电极中的任意两个像素电极上。在本实施例中，以“将光敏晶体管T2设置在绿色像素电极和蓝色像素电极上，即两个光敏晶体管T2，一个电连接于一像素电路单元10的绿色像素电极，另一个电连接于另一像素电路单元10的蓝色像素电极，”为例进行说明，但并不限于此。而图2为进行激光照射时的效果图，即绿色像素电极和蓝色像素电极对应的显示画面为黑色，而红色像素电极对应的显示画面为正常显示，即为红色。因此，在当投影时，荧幕上会投影出红点。
当然，如果光敏晶体管T2连接于红色像素电极和绿色像素电极上时，则荧幕会投影出蓝色点。
另外，在一些其他实施例中，光敏晶体管也可以连接于所述红色像素电极、绿色像素电极和蓝色像素电极中的一种像素电极上，即将光敏晶体管仅连接于在红色像素电极、绿色像素电极和蓝色像素电极中的一种。那样在进行投影时，荧幕中会出现其他两种颜色。
本实施例以光敏晶体管连接在绿色像素电极和蓝色像素电极上为例进行说本实施例的原理，原理如下：
当用户用激光笔照射本实施例的显示面板100时，在激光笔照射的区域中，该区域包括有红色像素、绿色像素和蓝色像素，光敏晶体管T2设置在绿色像素和蓝色像素中。
其中，光敏晶体管T2吸收激光导通时，该区域的连接有光敏晶体管T2的像素电路单元10的绿色像素电极的电压和蓝色像素电极的电压被拉到公共电极Com的低准位，VA液晶没有压差，液晶不发生偏转，光线透不过液晶，绿色像素和蓝色像素的不显示画面为黑色，而在该区域中的红色像素由于没有连接光敏晶体管T2，所以其像素电路单元10的电压没有被拉低则正常显示颜色，这样使激光照射的区域显示非白色，能进行投影。
本申请还涉及一种显示装置，包括一显示面板，所述显示面板包括阵列基板，阵列基板包括栅线和数据线，其中，所述阵列基板包括：
公共电极；

在本申请的显示装置中，所述显示面板还包括一二极管，所述二极管的一端连接于所述节点，所述二极管的另一端连接于所述公共电极。
相较于现有技术的显示面板，本申请的显示面板以及显示装置通过在像素电路单元外接入一个光敏晶体管，当光敏晶体管未吸收外界激光时，其不导通，显示区的垂直取向排列（Vertically aligned，VA）液晶电压正常，此时显示画面正常；当用户用激光笔照射本实施例的显示面板时，在激光笔照射的区域中，光敏晶体管吸收激光导通时，该区域显示区的连接有光敏晶体管的像素电路单元的电压被拉到公共电极的低准位，VA液晶没有压差，液晶不发生偏转，光线透不过液晶，该像素电路单元对应的画面为黑色，而在激光照射区域中的其他没有连接光敏晶体管的像素电路单元则正常显示颜色，这样使激光照射的区域显示非白色，；解决了现有的液晶显示面板无法进行激光笔投影的技术问题。
