本发明提供一种显示装置,所述显示装置包括如图2-6所示的显示面板。
如图2所示,显示面板100包括第一电极层101、液晶层102以及第二电极层103。
可以理解的,所述显示面板100可以划分为显示区和非显示区。
其中,所述液晶层102设于所述第一电极层101、所述第二电极层103之间,所述液晶层102包括多个液晶分子1021;所述第二电极层103与所述第一电极层101相对设置,如图3所示,所述第二电极层103包括第一区域104,所述第一区域104与所述非显示区相对设置,作用在所述第一电极层101和所述第二电极层103的所述第一区域104的电压相等,使得位于所述第一电极层101和所述第二电极层103的所述第一区域104之间的多个所述液晶分子1021不偏转。
需要注意的是,当所述液晶分子1021对应的上下方具有电压差时,所述液晶分子1021可以旋转,从而可以使得所述显示面板100的背光模组发出的光线透过所述液晶层102射出来;当所述液晶分子1021对应的上下方不具有电压差时,所述液晶分子1021不偏转,从而可以使得所述显示面板100的背光模组发出的光线不会透过所述液晶层102射出来。
可以理解的,由于所述第一电极层101和所述第二电极层103的所述第一区域104的电压相等,当所述显示面板100在进行图像显示时,可以保证导致两者之间的所述液晶分子102不偏转,以至于所述非显示区可以无光线通过,从而不进行图像显示。
在一实施例中,所述第一电极层101可以为一整片导电材料,即所述第一电极层101上任意区域的电压值可以相等。
在一实施例中,所述第二电极层103的所述第一区域104可以不经过图案化处理,直接采用导电材料制备所述第一区域104。
在一实施例中,如图3所示,所述第二电极层103包括多个数据电极1031和多个像素单元1032;其中,选取同排设置的所述多个像素单元1032以及周围的相关区域作为区域106。
其中,所述多个数据电极1031相互平行设置,所述多个像素单元1032设于相邻的两个所述数据电极1031之间。进一步的,所述相邻的两个数据电极1031之间可以设置多个所述数据电极1031,并且相邻的两个数据电极1031之间的所述多个数据电极1031可以沿着对应的所述数据电极1031的延伸方向设置。
在一实施例中,如图4所示,在所述区域106中,所述多个像素单元1032包括多个目标像素单元10321,所述目标像素单元10321部分位于所述第一区域104,所述目标像素单元10321包括第一目标子区域1033,所述第一目标子区域1033位于所述第一区域104,作用在所述目标像素单元10321的所述第一目标子区域1033和所述第一电极层101的电压相等,其中,选取同排设置的所述多个目标像素单元10321以及周围的相关区域作为区域107。
可以理解的,由于所述第一目标子区域1033设于所述第一区域104,即与所述显示面板100的非显示区相对应,将所述第一目标子区域1033和所述第一电极层101的电压设置相等,可以使得两者之间的所述液晶分子1021不偏转,以至于两者之间可以无光线通过,从而不进行图像显示。
在一实施例中,如图5所示,所述第二电极层103还包括第二区域108,所述第二区域108与所述显示区的部分区域相对设置。所述目标像素单元10321还包括第二目标子区域1035,所述第二目标子区域1035位于所述第二区域105,作用在所述目标像素单元10321的所述第二目标子区域1035和所述第一电极层101的电压相等。
特别的,所述目标像素单元10321包括多个目标子像素1036,每一所述目标像素单元10321中,至少一所述目标子像素1036与所述第二目标子区域1035的重叠面积为零。其中,所述目标子像素1036可以为红色子像素、绿色子像素或者蓝色子像素。
例如,位于所述目标像素单元10321最左侧的目标子像素1036与所述第二目标子区域1035的重叠面积可以为零,而位于所述目标像素单元10321中的其他所述目标子像素1036与所述第二目标子区域1035的重叠面积可以不为零。
进一步的,在同一所述目标像素单元10321的每一所述目标子像素1036中,所述第一目标子区域1033和所述第二目标子区域1035的总面积所占的比例相等。例如,位于所述目标像素单元10321最左侧的目标子像素1036中所述第一目标子区域1033的面积所占的比例,等于位于所述目标像素单元10321中间的、或者右侧的目标子像素1036中所述第一目标子区域1033和所述第二目标子区域1035的总面积所占的比例。
需要注意的,对于每一所述目标像素单元10321而言,可以先确定所述目标子像素1036中,包含所述第一目标子区域1033比例最高的目标子像素1036,并且以此目标子像素1036中所述第一目标子区域1033占比为标准,在其他的每一目标子像素1036中,选取相应的第二目标子区域1035所占的对应的子区域,以构成所述第二目标子区域1035,以保证在同一所述目标像素单元10321的每一所述目标子像素1036中,所述第一目标子区域1033和所述第二目标子区域1035的总面积所占的比例相等。
可以理解的,在保证作用在所述目标像素单元10321的所述第一目标子区域1033和所述第一电极层101的电压相等的前提下,使得所述第二目标子区域1035和所述第一电极层101的电压相等,即针对同一所述目标像素单元10321而言,在进行图像显示时,每一所述目标子像素1036中所述用于图像显示的像素面积百分比相同,使得不同颜色的子像素对对应的所述目标像素单元10321的面积贡献比例相同,可以进一步解决色偏问题。
在一实施例中,所述第二区域108可以与所述第一区域104相邻设置。进一步的,所述第二电极层103还包括第三区域,所述第三区域为所述第二电极层103中除去所述第一区域104以及所述第二区域108以外的其它区域;所述目标像素单元10321还包括第三目标子区域,所述第三目标子区域位于所述第三区域,作用在所述目标像素单元10321的所述第三目标子区域和所述第一电极层101的电压相异。
在一实施例中,如图6所示,在所述区域107中,所述第二电极层102还包括第四区域105,所述第四区域105与所述显示区相对设置;进一步的,所述目标像素单元10321还包括第四目标子区域1034,所述第四目标子区域1034位于所述第四区域105,并且所述第一目标子区域1033与对应的所述第四目标子区域1034可以构成对应的完整的所述目标像素单元10321;其中,作用在所述目标像素单元10321的所述第三目标子区域1034和所述第一电极层101的电压不相等。
可以理解的,对于每一所述目标像素单元10321而言,将所述第一目标子区域1033的电压设置为和所述第一电极层101的电压相等,以及将所述第四目标子区域1034的电压设置为和所述第一电极层101的电压不相等,即可以使得所述目标像素单元10321中位于非显示区上方的所述液晶分子1021不偏转,以及所述目标像素单元10321中位于显示区上方的所述液晶分子1021偏转;以实现在进行图像显示时,所述非显示区的像素可以不发光,而显示区的像素可以发光,有较为明显的发光界限,改善了现有技术中的锯齿现象。
在一实施例中,如图3-5所示,作用在所述数据电极1031和所述第一电极层101的电压相等。
可以理解的,所述第一电极层101的任意区域的电压值相等,即所述第二电极层103中的不同区域与所述第一电极层101的电压差可以使得位于所述第一电极层101和所述第二电极层103中的对应区域的液晶分子1021发生偏转,从而使得光线射出。其中,位于所述数据电极1031两侧的所述像素单元1032的电压值一般不相同,对应上方的液晶分子偏转程度也不相同,为了避免所述两个像素单元1032对应的光线相互干扰,因此可以在所述两个像素单元1032之间的区域设置所述数据电极1031,并且将所述数据电极1031的电压与所述第一电极层101的电压设置为相同值,使得所述两个像素单元1032之间的区域上方的液晶分子不偏转,从而避免所述两个像素单元1032对应的光线通过所述两个像素单元1032之间的区域上方的液晶偏转而射出,解决了相邻像素单元之间的漏光问题。
在一实施例中,所述多个数据电极1031和所述多个像素单元1032的组成材料相同。
需要注意的,所述数据电极1031是通过加上与所述第一电极层101相等的电压来解决漏光问题的,因此所述数据电极1031和所述像素单元1032可以采用相同的材料制备,所述相同的材料应该为导电材料,例如,所述多个数据电极1031和所述多个像素单元1032的组成材料可以包括透明的氧化铟锡。可以理解的,由于所述多个数据电极1031和所述多个像素单元1032的组成材料相同,所述第二电极层103上的所述多个数据电极1031和所述多个像素单元1032可以同层制备,例如两者可以同时通过图案化形成,简化了显示面板的制备流程。
在一实施例中,所述第一电极层101和所述第二电极层103的组成材料相同。
其中,所述所述第一电极层101和所述第二电极层103可以采用在钠钙基或硅硼基基片玻璃的基础上,利用溅射、蒸发等多种方法镀上一层氧化铟锡膜制备而成。
以上对本发明实施例所提供的一种显示面板以及包含所述显示面板的显示装置的结构进行了详细介绍,本文中应用了具体个例对本发明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发明的技术方案及其核心思想;本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明各实施例的技术方案的范围。
