Description

像素阵列结构和液晶显示面板
技术领域
本发明是有关于一种像素阵列结构和具有所述像素陈列结构的液晶显示面板。
背景技术
液晶显示设备具有诸如重量轻、厚度薄、功耗低等之类的各种优势,使得液晶显示设备被广泛应用。液晶显示设备利用在两个电极(例如像素电极和公共电极)之间形成的电场来控制液晶的取向,以显示图像。像素电极和公共电极可以形成在不同的基板上。不过,近来,越来越多地使用包括形成在相同基板上的像素电极和公共电极的面线切换或面到线切换式液晶面板(例如PLS型LCD),来扩大视角等。然而,通过PLS型液晶面板呈现的颜色可能依赖于视角而改变。当在像素中形成多个畴来改善色变问题时,在各畴边界附近形成液晶纹理,从而降低亮度,影响显示效果和品质。
发明内容
本发明所要解决的技术问题在于提供一种像素阵列结构和具有所述像素陈列结构的液晶显示面板,能够实现多畴显示,提升显示品质。
为了实现上述目的,本发明实施方式提供如下技术方案:
一种像素阵列结构,包括多个呈阵列分布的像素区,所述像素区的分布形成了彼此垂直的行方向和列方向,每个像素区内设有至少一个开口,所述开口包括依次连续相连通的第一开口区、第二开口区和第三开口区,所述第一开口区自所述第二开口区的一端垂直延伸,所述第三开口区自所述第二开口区的另一端垂直延伸,且所述第三开口区的延伸方向与所述第一开口区的延伸方向相反,所述第一开口区和所述第三开口区在所述列方向上的投影相邻接,所述第一开口区和所述第三开口区在所述行方向上投影分别邻接在所述第二开口区在所述行方向上的投影的两侧。
其中,相邻的两个所述像素区之间包括一个共用边,相邻的两个所述像素区内的所述开口以所述共用边为中心呈镜像对称分布。
其中,每个所述像素区均呈四边形,所述开口与所述像素区的其中一个边相连通,所述开口与所述像素区的其它三个边之间均相间隔。
其中,每个像素区内的开口的数量为两个或两个以上,所述两个或两个以上的所述开口彼此平行。
其中,所述第二开口区呈直形条状,且与所述行方向呈45度夹角。
本发明还公开一种液晶显示面板,包括显示区,所述显示区内设有像素阵列结构,所述像素阵列结构包括多个呈阵列分布的像素区,所述像素区的分布形成了彼此垂直的行方向和列方向,每个像素区内设有至少一个开口,所述开口包括依次连续相连通的第一开口区、第二开口区和第三开口区,所述第一开口区自所述第二开口区的一端垂直延伸,所述第三开口区自所述第二开口区的另一端垂直延伸,且所述第三开口区的延伸方向与所述第一开口区的延伸方向相反,所述第一开口区和所述第三开口区在所述列方向上的投影相邻接,所述第一开口区和所述第三开口区在所述行方向上投影分别邻接在所述第二开口区在所述行方向上的投影的两侧。
其中,相邻的两个所述像素区之间包括一个共用边,相邻的两个所述像素区内的所述开口以所述共用边为中心呈镜像对称分布。

其中,所述第二开口区呈直形条状,且与所述行方向呈45度夹角。
本发明通过每个像素区内的开口的设计,即,所述开口包括依次连续相连通的第一开口区、第二开口区和第三开口区,且所述第一开口区自所述第二开口区的一端垂直延伸,所述第三开口区自所述第二开口区的另一端垂直延伸,使得像素区内的液晶在不同的方向上排列,在每个像素区内形成多个畴,可以防止观察者所察觉的颜色由于视角的变化而变化,使得液晶显示面板的显示品质得到提升,改善画面质量。
附图说明
为了更清楚地说明本发明的技术方案,下面将对实施方式中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施方式,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,还可以如这些附图获得其他的附图。
图1是本发明一种实施方式提供的像素阵列结构的示意图。
图2是本发明一种实施方式提供的像素阵列结构中液晶分布的示意图。
具体实施方式
下面将结合本发明实施方式中的附图,对本发明实施方式中的技术方案进行清楚、完整地描述。
本发明供了一种液晶显示面板,适用于各种尺寸的IPS模式的液晶显示屏。所述液晶显示面板包括显示区,所述显示区内设有像素阵列结构。所述像素阵列结构具体如下描述。
请参阅图1,像素阵列结构包括多个呈阵列分布的像素区100,所述像素区100的分布形成了彼此垂直的行方向D1和列方向D2,图1中只显示了两行两列的像素区100作为代表描述。每个像素区100内设有至少一个开口10,本实施方式中,每个像素区100内的开口10的数量为两个或两个以上,所述两个或两个以上的所述开口10彼此平行,相邻的开口10之间彼此间隔。所述两个或两个以上的所述开口10可以沿着列方向D2层层排列,也可呈倾斜的阶梯状的层层排列。
本实施方式中,每个所述像素区100均呈四边形,所述开口10与所述像素区100的其中一个边相连通,所述开口10与所述像素区100的其它三个边之间均相间隔,即呈不连通的状态。
相邻的两个所述像素区100之间包括一个共用边,相邻的两个所述像素区100内的所述开口10以所述共用边为中心呈镜像对称分布。如图1所示,像素区100包括第一像素区101、第二像素区102、第三像素区103和第四像素区104,第一像素区101与第二像素区102之间包括第一共用边L1,第一像素区101与第三像素区103之间包括第二共用边L2,第一共用边L1垂直于第二共用边L2,第一像素区101的开口10与第二像素区102的开口10是不连续的。第一像素区101内的开口10和第二像素区102内的开口10以第一共用边L1为中心轴呈镜像对称。第一像素区101内的开口10与第三像素区103内的开口10以第二共用边L2为中心轴呈镜像对称。
所述开口10包括依次连续相连通的第一开口区12、第二开口区14和第三开口区16,所述第一开口区12自所述第二开口区14的一端垂直延伸,所述第三开口区16自所述第二开口区14的另一端垂直延伸,且所述第三开口区16的延伸方向与所述第一开口区12的延伸方向相反,所述第一开口区12和所述第三开口区16在所述列方向D2上的投影相邻接,所述第一开口区12和所述第三开口区16在所述行方向D1上投影分别邻接在所述第二开口区14在所述行方向D1上的投影的两侧。
具体而言,所述第二开口区14呈直形条状,且与所述行方向呈45度夹角。第一开口区12和第三开口区16亦呈直形条状。
所述开口10的设置用于控制像素区内的液晶分子的排布方向,如图2所示,当向每个像素电极施加电压时,相邻的像素区内的液晶分子LC的排布方向均不同,在同一个像素区100内,位于第一开口区12的液晶分子LC、位于第二开口区12的液晶分子LC及位于第三开口区16的液晶分子LC的排布方向也不相同,这样就形成了多个畴,使得液晶显示面板能够实现多视角的显示。
本发明通过每个像素区100内的开口10的设计,即,所述开口10包括依次连续相连通的第一开口区12、第二开口区14和第三开口区16,且所述第一开口区12自所述第二开口区14的一端垂直延伸,所述第三开口区16自所述第二开口区14的另一端垂直延伸,使得像素区100内的液晶LC在不同的方向上排列,在每个像素区100内形成多个畴,可以防止观察者所察觉的颜色由于视角的变化而变化,使得液晶显示面板的显示品质得到提升,改善画面质量。
以上所述是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也视为本发明的保护范围。
