技术领域

本发明提供一种显示面板，所述显示面板包括但不限于如图1-5所示的实施例。
在一实施例中，如图1所示，所述显示面板100包括基板101、设置在所述基板101上的线路层102、以及设置在所述线路层102上的像素层103。所述线路层102包括多条数据线1021，所述多条数据线1021相互平行设置；所述像素层103包括多个遮挡电极1031和多个像素电极1032，所述遮挡电极1031与所述数据线1021相对设置，所述像素电极1032设置在相邻的两所述遮挡电极1031之间。
其中，所述基板101可以为玻璃基板，所述玻璃基板的组成材料可以包括石英粉、碳酸锶、碳酸钡、硼酸、硼酐、氧化铝、碳酸钙、硝酸钡、氧化镁、氧化锡、氧化锌中的至少一种。
可以理解的，所述线路层102还可以包括多条栅极线，多个薄膜晶体管器件、以及其他金属线路，所述多条栅极线相互平行设置，所述多条栅极线、多条数据线1021相交形成多个矩形区域，所述薄膜晶体管器件设置在所述矩形 区域中，所述薄膜晶体管器件的源极或者漏极与所述像素电极1032电性连接；所述栅极线用于向多个所述薄膜晶体管器件传递行信号，以控制某一行薄膜晶体管器件的导通，所述数据线1021用于向多个所述薄膜晶体管器件传递列信号，以控制对应的像素电极1032画面显示。
其中，所述遮挡电极1031和所述像素电极1032可以采用透明导电材料制备，具体的，所述遮挡电极1031和所述像素电极1032的组成材料可以为ITO材料。
在一实施例中，如图2所示，所述显示面板100还包括彩膜基板104，所述彩膜基板104与设于所述像素层103远离所述基板101的一侧，且所述彩膜基板104与所述基板101相对设置，所述像素层103与所述彩膜基板104之间设置有多个液晶分子，所述液晶分子用于偏转使得光线通过。
具体的，所述彩膜基板104包括公共电极1041，所述公共电极1041摄于所述彩膜基板104中靠近所述像素层103的一侧，所述公共电极1041可以为一整面的透明导电材料，例如ITO材料。
可以理解的，当对所述显示面板100进行配向时，在所述像素层103与所述公共电极1041上加上不同的电压后，在所述像素层103与所述公共电极1041之间会形成纵向的电场，位于所述像素层103与所述公共电极1041之间的液晶分子会发生偏转形成预倾角；进一步的，当所述像素层103进行图案化形成多个电极以后，在上述相同的情况下，在每一所述电极与所述公共电极1041之间会形成电场，即所述电场的所在面沿竖直方向，所述电场的所在面在所述像素层103上的投影与所述多个电极重合，所述液晶分子在所述电场的作用下进行偏转。
特别的，如图3所示，所述遮挡电极1031包括多个子遮挡电极10311，所述多个子遮挡电极10311与所述数据线1021平行设置。如图4所示，由于所述多个子遮挡电极10311与所述数据线1021相互平行，故在所述多个子遮挡电极10311与所述公共电极1041之间均会形成多个相互平行的电场01，因此位于每一所述子遮挡电极10311上方的液晶分子02会在所述电场01的作用下进行偏转，以形成预倾角θ。
可以理解的，例如对于某一所述遮挡电极1031上的每一液晶分子02而言， 每一液晶分子02除了受到对应的电场01的作用力，还会受到相邻的液晶分子02的相互作用力，使得每一液晶分子02更容易进行上述的偏转；因此，位于所述遮挡电极1031和所述像素电极1032之间区域的上方的液晶分子02也更容易进行上述的偏转，可以理解的，当所述多个子遮挡电极10311的数目越多，液晶分子02进行上述的偏转的容易度越高。
如表1所示，表1为B上方的液晶分子处于不同的水平偏转角、以及A、B、C上方的液晶分子处于不同的竖直偏转角下的情况下对应的A、B、C处的光线的穿透率。其中，水平偏转角表示液晶分子在水平方向与水平向右的向量的夹角，水平偏转角为0°表示液晶分子朝水平向右的方向；竖直偏转角表示液晶分子在竖直方向与水平面的夹角，也即图4中的θ；A、B、C分别表示所述遮挡电极1031上方的液晶分子、所述遮挡电极1031与所述像素电极1032之间的区域上方的液晶分子、所述像素电极1032上方的液晶分子。观察表一可知，所述A、B、C上方的液晶分子的竖直偏转角一定时，当所述B上方的液晶分子的竖直偏转角为90°时，对应的A、B、C处光线的穿透率最大。

表1
如图5所示，表示所述像素层103中不同位置对应的透光率的曲线图。其中，横坐标“x”表示距离所述显示面板100的边框的距离，此处认为所述边框位于靠近所述遮挡电极1031的一侧；纵坐标“Tr％”表示透光率。具体的，“10”表示所述遮挡电极1031与所述像素电极1032之间的区域，所述“20”表示当所述“10”上方的液晶分子的水平偏转角为0°时对应的透光率的曲线，所述“30”、“40”表示当所述“10”上方的水平偏转角接近90°时对应的透 光率的曲线。观察图5，我们可以发现，当所述遮挡电极1031与所述像素电极1032之间的区域上方的液晶分子的水平偏转角为90°附近时，对应的透光率较大。
综合上文可知，当所述多个子遮挡电极10311与所述数据线1021平行设置时，所述多个子遮挡电极10311的数目越多，液晶分子02进行上述的偏转的容易度越高，而上述偏转方向包含了液晶分子02在水平方向沿所述数据线1021的方向偏转，所述数据线1021的方向也可以设置为所述水平偏转角为90°的方向，因此，将所述遮挡电极1031设置为多个子遮挡电极10311、且所述多个子遮挡电极10311与所述数据线1021平行，可以增加所述遮挡电极1031与所述像素电极1032之间的区域的光线的穿透率。
在一实施例中，如图3所示，所述像素电极1032包括边界电极10321，所述边界电极10321设于所述像素电极1032中靠近所述遮挡电极1031的一侧，所述边界电极10321为条状，所述边界电极10321与所述子遮挡电极10311平行设置。其中，相邻的两所述子遮挡电极10311之间的距离a不小于2微米；所述遮挡电极1031与所述像素电极1032之间的距离b不小于2微米；所述边界电极10321的宽度c不小于2微米，且不大于6微米，进一步的，所述边界电极10321的宽度c可以为2微米。
可以理解的，当所述边界电极10321为条状，且所述边界电极10321与所述子遮挡电极10311平行设置时，位于所述边界电极10321和所述子遮挡电极10311上方的液晶分子均可以在水平偏转角为90°的前提下，沿着竖直方向进行偏转，同理，由于边界电极10321的存在，且液晶分子之间存在互作用力，位于所述像素电极1032和所述遮挡电极1031电极之间的区域上方的液晶分子在两侧的液晶分子的影响下，也更加容易实现水平偏转角为90°。
其中，所述像素电极1032还包括内部电极10322，所述内部电极10322可以包括多个分支电极，所述多个分支电极可以沿一预设方向相互平行设置，所述预设方向不同于所述边界电极10321的设置方向，且所述预设方向不垂直于所述边界电极10321的设置方向。同理，由于液晶分子之间存在互作用力，所述多个分支电极上方的液晶分子在水平方向均可以沿所述预设方向偏转，以增加该处的穿透率。
在一实施例中，所述遮挡电极1031的宽度大于对应的数据线1021的宽度，可以理解的，所述遮挡电极1031可以完全遮挡住对应的数据线1021，以防止暗态下的漏光，提高对比度。
在一实施例中，如图6所示，所述显示面板100还包括第一配向层105、第二配向层106，所述第一配向层105设于所述像素层103上，所述第二配向层106设于所述公共电极1041靠近所述像素层103的一侧，所述第一配向层105包括多个第一配向部，所述多个第一配向部与所述多个遮挡电极1031、所述多个像素电极1032相对设置，所述第二配向层106包括多个第二配向部，所述多个第二配向部可以与所述多个第一配向部相互平行或者垂直；另外的，所述液晶分子中还可以包括配向粒子。
其中，所述第一配向层105、第二配向层106的组成材料可以包括聚酰亚胺，所述配向粒子可以为反应单体，在上述配向的条件下，所述配向粒子可以在所述第一配向层105、第二配向层106的作用下，带动所述液晶分子进行偏转，使得所述液晶分子更容易发生偏转，提高液晶分子的偏转效率。
本发明提供另一种显示面板，所述显示面板包括但不限于如图7所示的实施例。
在一实施例中，如图7所示，所述显示面板200包括基板201、设置在所述基板201上的线路层202、设置在所述线路层202上的像素层203、以及电压产生器204。所述线路层202包括多条数据线2021，所述多条数据线2021相互平行设置；所述像素层203包括多个遮挡电极2031和多个像素电极2032，所述遮挡电极2031与所述数据线2021相对设置，所述像素电极2032设置在相邻的两所述遮挡电极2031之间，所述电压产生器204与所述多个遮挡电极2031、以及所述多个像素电极2032电性连接。
其中，所述基板201、所述线路层202、所述遮挡电极2031、以及所述像素电极2032可以参考上文关于所述基板101、所述线路层102、所述遮挡电极1031、以及所述像素电极1032的相关描述。
在一实施例中，所述显示面板还包括彩膜基板，所述彩膜基板可以包括公共电极，所述彩膜基板、公共电极可以参考上文关于所述彩膜基板104、公共电极1041的相关描述。
特别的，所述电压产生器204用于当所述显示面板200进行配向时，向所述多个遮挡电极2031和所述多个像素电极2032输入相同的电压。需要注意的是，当所述公共电极上的电压一定时，若所述遮挡电极2031与所述像素电极2032上的电压相同时，在水平方向上，所述遮挡电极2031与所述像素电极2032之间就没有电压差，即所述遮挡电极2031与所述像素电极2032之间没有形成电场，则位于所述遮挡电极2031与所述像素电极2032之间区域上方的液晶在水平方向的偏转方向只受到相邻的液晶分子的影响。
进一步的，所述像素电极2032包括边界电极，所述边界电极设于所述像素电极2032中靠近所述遮挡电极2031的一侧，所述边界电极为条状，所述边界电极与所述遮挡电极2031平行设置。综合上文的分析，所述遮挡电极2031与所述像素电极2032之间区域上方的液晶在水平方向的偏转方向与所述遮挡电极2031、所述边界电极的设置方式一致，降低了所述遮挡电极2031与所述像素电极2032之间电场对两者之间区域上方液晶分子的影响，提高了穿透率。
在一实施例中，所述遮挡电极包括多个子遮挡电极，所述多个子遮挡电极与所述数据线平行设置。
其中，所述边界电极、所述多个子遮挡电极的具体设置方式可以参考上文的相关描述。
本发明提供了显示面板，包括基板、线路层、像素层，线路层包括多条平行设置的数据线，像素层包括多个遮挡电极和多个像素电极，遮挡电极与数据线相对设置，通过将遮挡电极设置为包括多个子遮挡电极，且所述多个子遮挡电极与所述数据线平行设置，减少了遮挡电极和像素电极之间的暗条纹，提高了显示面板的穿透率。可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
