Description
本发明涉及显示技术领域,特别涉及一种曲面显示面板及曲面显示装置。
在传统的VA(Vertical
Alignment,垂直配向)型显示器中,为了解决视角的色偏问题,一般会将子像素(Sub-pixel)分为若干个分区(Domain)。
子像素中的像素单元通常呈鱼骨状结构,分区之间的交界区域一般被称为ITO(Indium Tin
Oxide,氧化铟锡) Trunk(躯干)。
随着分区的增多,ITO Trunk也会增多。

在所述第一曲面基板405中,不同的色阻区域的曲率半径可以相同或不相同,同理,在所述第二曲面基板401中,不同的像素区域的曲率半径可以相同或不相同。
在本实施例中,所述像素阵列层还包括至少一屏蔽电极305,所述屏蔽电极305设置于所述像素电极的至少一侧,如图3所示。所述屏蔽电极305可以包围所述像素电极。
具体地,所述屏蔽电极305设置于相邻两个像素单元之间的区域上,所述屏蔽电极305用于保护与其对应的像素单元中的液晶分子免受相邻的像素单元中的电场作用的影响。也就是说,所述屏蔽电极305用于防止相邻的两个像素单元中的一者对另一者产生的电场干扰。
其中,所述屏蔽电极305在第一方向上可以与所述像素电极分别位于不同的层别。所述第一方向为沿所述像素区域的半径,从所述像素区域所在的曲面指向其圆心的方向。例如,所述屏蔽电极305在所述第一方向上位于所述像素电极的上方或下方。

所述色阻区域与所述第二区域410对应。也就是说,所述色阻区域在所述第二曲面基板401上具有第一投影,所述第一投影与所述像素区域的所述第二区域410对应,而所述第一区域410与所述第一投影不重合。
在上述技术方案中,所述像素电极仅有一个分区,因此可以有效减少出现所述暗纹。此外,上述技术方案可以使得所述主干电极402的成像缺陷隐藏在所述色阻单元406所形成的影像的边缘,也就是说,所述主干电极402的阴影不会出现在所述色阻单元406所形成的所述影像中。因此,可以提高所述像素单元的穿透率,同时提高所述像素单元的成像质量。
此外,所述曲面彩色滤光片基板203上的防漏光条407的至少一部分在所述第二曲面基板401上具有第二投影,所述第二投影与所述第一区域410重合。也就是说,所述第二投影位于所述第一区域410上。其中,所述防漏光条407为所述曲面彩色滤光片基板203上的黑色矩阵层(BM,Black
Matrix)的一部分(一段)。
尽管已经相对于一个或多个实现方式示出并描述了本发明,但是本领域技术人员基于对本说明书和附图的阅读和理解将会想到等价变型和修改。本发明包括所有这样的修改和变型,并且仅由所附权利要求的范围限制。特别地关于由上述组件执行的各种功能,用于描述这样的组件的术语旨在对应于执行所述组件的指定功能(例如其在功能上是等价的)的任意组件(除非另外指示),即使在结构上与执行本文所示的本说明书的示范性实现方式中的功能的公开结构不等同。此外,尽管本说明书的特定特征已经相对于若干实现方式中的仅一个被公开,但是这种特征可以与如可以对给定或特定应用而言是期望和有利的其他实现方式的一个或多个其他特征组合。而且,就术语“包括”、“具有”、“含有”或其变形被用在具体实施方式或权利要求中而言,这样的术语旨在以与术语“包含”相似的方式包括。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
