本申请主张在2015年9月24日在中国提交的中国专利申请号No.201510618603.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及显示技术领域，尤其涉及一种阵列基板、曲面显示面板、曲面显示装置。
背景技术
目前在曲面(Curved)薄膜场效应晶体管液晶显示(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)领域中，一般采用将平板(Plane)贴合的液晶显示面板在外力下弯曲，根据设计尺寸和观赏距离来决定弯曲程度，形成曲面结构。如图1所示，将平板贴合的彩膜基板11和阵列基板12在外力作用下进行弯曲，弯曲的曲率半径R根据设计尺寸和观赏距离来决定。彩膜基板11和阵列基板12处于平面时，彩膜基板11的像素透光区与阵列基板12的像素电极区呈一一对应。当将彩膜基板11和阵列基板12弯曲后，彩膜基板11的像素透光区和阵列基板12的像素电极区发生剧烈位移，且中心线10的左、右两个区域的位移方向相反。
相关技术中的共平面切换(In-Plane-Switching，IPS)和边缘场面内转动(Fringe Field Switching，FFS)模式的液晶显示面板为实现宽视角、高透过率、快速响应等优点，一般采用上、下双畴和狭缝倾角设计的像素电极结构。如图2所示，像素电极21为狭缝状电极，位于一个亚像素单元内的像素电极21的形状呈尖括弧“＞”形。像素电极21的边缘区域和中部区域受周围电场和上、下畴狭缝电极交叉变化的影响，边缘区域和中部区域的液晶偏转较为紊乱，透过率较低，形成暗纹区22。整个像素显示区的液晶偏转和透过率呈非对称分布。
当相关技术中的阵列基板中的像素电极采用上面描述的上、下双畴和狭缝倾角设计的像素电极结构，阵列基板与彩膜基板组成的液晶显示面板不发生弯曲时，每一个像素基本表现出相同的开口率和透过率，因此整个液晶显示面板各个区域基本表现出相同的亮度，透过率差异不大，人眼视觉效果较好。如图3所示，31表示从一个像素中的三个亚像素射出的光线，32表示位于彩膜基板11和阵列基板12之间的液晶层，33表示位于彩膜基板11和阵列基板12之间的隔垫物。
如图4所示，当阵列基板与彩膜基板组成的液晶显示面板发生弯曲时，彩膜基板11的像素透光区和阵列基板12的像素电极区发生剧烈位移，且中心线10的左、右两个区域的位移方向相反，液晶显示面板的漏光和混色非常严重。目前一般采取增加黑矩阵的宽度的设计来补偿漏光和混色严重的问题，但通过这种方法会降低液晶显示面板的开口率和透过率。从图4和图2可以看到，像素电极在暗纹区左右非完全对称，中心线10左侧区域光的透过率小于中心线10右侧区域光的透过率，导致液晶显示面板在视觉上的不自然和画质的不良。
综上所述，相关技术中的平板显示面板在外力作用下发生弯曲时，容易导致显示面板在视觉上的不自然和画质的不良。

具体实施方式
本公开的一些实施例提供了一种阵列基板、曲面显示面板、曲面显示装置，用以实现当显示面板在外力作用下发生弯曲时，提高显示面板的视觉效果和画质。
为了使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开作进一步地详细描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本公开保护的范围。
下面结合附图详细介绍本公开的一些实施例提供的阵列基板。
如图5所示，本公开的一些实施例提供了一种阵列基板，包括若干阵列排 列的像素单元51。每一像素单元51包括至少两个亚像素单元，图5仅以包括三个亚像素单元为例进行介绍。每一亚像素单元包括一像素电极52和公共电极(图中未示出)，其中，位于同一像素单元51中的像素电极52或公共电极的结构相同，位于不同像素单元51中的像素电极52或公共电极的结构至少包括第一种结构和第二种结构两种不同的结构，图5仅以像素电极的结构包括两种不同的结构为例进行介绍。
像素电极52或公共电极以阵列基板50的中心轴53为轴对称设置。中心轴53为位于阵列基板50的中心并沿平行于阵列基板50的方向延伸的直线，且其在阵列基板50弯曲后延伸方向不发生变化。
本公开的一些实施例仅以像素电极为例进行介绍，公共电极的具体设置与像素电极相同，这里不再赘述。
如图5所示，本公开的一些实施例中的像素电极52的结构为狭缝状。狭缝以阵列基板的中心轴53为轴对称设置，每一像素电极52包括若干排列方向一致的狭缝，图5中每一像素电极52中仅示出了一个狭缝。
如图5所示，第一种结构的像素电极52中的每一狭缝521的中间区域具有弯曲点，沿第一预设方向弯曲，或第一种结构的像素电极52中的每一狭缝沿第一预设方向倾斜。第二种结构的像素电极52中的每一狭缝522的中间区域具有弯曲点，沿第二预设方向弯曲，或第二种结构的像素电极52中的每一狭缝沿第二预设方向倾斜，本公开的一些实施例中第一预设方向为水平向左的方向，第二预设方向为水平向右的方向。
如图5所示，狭缝状的像素电极52中的狭缝521在中间区域的弯曲点，与该狭缝521的两个端点构成一个以弯曲点为顶点的等腰三角形，弯曲点为狭缝521的中心点。狭缝状的像素电极52中的狭缝522在中间区域的弯曲点，与该狭缝522的两个端点构成一个以弯曲点为顶点的等腰三角形，弯曲点为狭缝522的中心点。
本公开的一些实施例中像素电极中的每一狭缝的中间区域的弯曲点与该狭缝的一个端点之间的连线为直线，与该狭缝的另一个端点之间的连接为直线， 如图5中示出的呈尖括弧“＜”状，或呈尖括弧“＞”状的狭缝。像素电极中的每一狭缝的中间区域的弯曲点与该狭缝的一个端点之间的连线为曲线，与该狭缝的另一个端点之间的连接为曲线，如呈圆括弧“(”状，或呈圆括弧“)”状的狭缝。
具体地，本公开的一些实施例中的像素电极52设计为不同的结构，如对于第一行中的像素单元，第一个像素单元中的像素电极的狭缝呈尖括弧“＜”状，第二个像素单元中的像素电极的狭缝呈尖括弧“＞”状，第三个像素单元中的像素电极的狭缝呈圆括弧“(”状，第四个像素单元中的像素电极的狭缝呈圆括弧“)”状，依此类推进行设计，只要保证像素单元中的像素电极以阵列基板的中心轴为轴对称即可。
当然，在实际设计时，还可以将阵列基板的中心轴一侧的像素单元分为四个不同的区域，第一区域中的像素单元中的像素电极的狭缝呈尖括弧“＜”状，第二区域中的像素单元中的像素电极的狭缝呈尖括弧“＞”状，第三区域中的像素单元中的像素电极的狭缝呈圆括弧“(”状，第四区域中的像素单元中的像素电极的狭缝呈圆括弧“)”状，依此类推设计中心轴另一侧的像素单元中的像素电极，使得阵列基板中心轴两侧的像素单元中的像素电极关于该中心轴对称。
为了更好的理解本公开，本公开的一些实施例中的图5仅示出了像素电极狭缝的轮廓结构，并不表示像素电极实际设计的结构，如本公开的一些实施例中的呈尖括弧“＞”状的像素电极52具体设计时可参照图2中像素电极的结构设计方式，这里不再赘述。
本公开的一些实施例中位于同一行的相邻两个像素单元中的像素电极的结构不同，其中，行方向与中心轴的延伸方向垂直。本公开的一些实施例在像素单元设计合理的情况下，也可以是同一行的相邻三个、四个及更多个像素单元中的像素电极的结构不同，只要保证像素单元中的像素电极以阵列基板的中心轴为轴对称即可。具体地，本公开的一些实施例中位于中心轴一侧同一行的像素单元中的像素电极的结构相同，位于中心轴另一侧同一行的像素单元中的 像素电极的结构相同。
可选地，如图5所示，本公开的一些实施例中位于同一列的像素单元中的像素电极的结构相同，列方向与中心轴53的延伸方向平行。
本公开的一些实施例中一个像素单元可以包括三个亚像素单元，该三个亚像素单元分别对应彩膜基板上的红色(R)色阻层、绿色(G)色阻层和蓝色(B)色阻层。当然，本公开的一些实施例中一个像素单元也可以包括四个亚像素单元，该四个亚像素单元分别对应彩膜基板上的红色(R)色阻层、绿色(G)色阻层、蓝色(B)色阻层和白色(W)色阻层。当然，在实际设计过程中，该四个亚像素单元也可以分别对应彩膜基板上的红色(R)色阻层、绿色(G)色阻层、蓝色(B)色阻层和黄色(Y)色阻层。本公开的一些实施例并不对像素单元中的亚像素单元对应的彩膜基板上的色阻层的具体类型做限定。
下面分别介绍本公开的一些实施例中一个像素单元包括三个亚像素单元和一个像素单元包括四个亚像素单元两种类型的像素单元中的像素电极的结构设计。
本公开的一些实施例以3840×2160分辨率的显示结构为例，其中，一个像素单元51包括三个亚像素单元，每个亚像素单元的长边沿阵列基板的短边方向，每个亚像素单元的短边沿阵列基板的长边方向，即每个亚像素单元的短边沿阵列基板曲面弯曲方向。如图6和图7所示，每一个亚像素单元通过该亚像素单元中的薄膜晶体管60与对应的一条栅极线以及对应的一条数据线连接。本公开的一些实施例中的阵列基板包括沿水平方向排列的2160条栅极线，第一行亚像素单元与第一条栅极线Gate1连接，最后一行亚像素单元与最后一条栅极线Gate2160连接。本公开的一些实施例中的阵列基板包括沿竖直方向排列的11520条数据线，第一列亚像素单元与第一条数据线Datal连接，最后一列亚像素单元与最后一条数据线Data11520连接。

如图7所示，本公开的一些实施例中位于中心轴53一侧同一行的像素单元中的像素电极的结构相同，位于中心轴53另一侧同一行的像素单元中的像素电极的结构相同，且位于中心轴53一侧和位于中心轴53另一侧的像素电极关于中心轴53对称。例如，图中位于中心轴53左侧的像素电极的狭缝呈尖括弧“＜”状，位于中心轴53右侧的像素电极的狭缝呈尖括弧“＞”状。可选地，本公开的一些实施例中位于同一列的像素单元中的像素电极的结构相同。
本公开的一些实施例设计两种不同结构的像素电极，图6中不同结构的像素电极交错周期性排布。图7中不同结构的像素电极分别位于中心轴的左、右两侧，中心轴左、右两侧的像素电极的结构呈对称设计。
当本公开的一些实施例中的阵列基板与对盒设置的彩膜基板在外力作用下弯曲时，阵列基板和彩膜基板组成的液晶显示面板中心轴左、右部分的像素单元的数量相同，且关于中心轴呈对称分布，因此与相关技术相比，本公开的一些实施例中彩膜基板的位移对液晶偏转和透光率的影响相同，仍能保持相同的透过率和亮度。而且，本公开的一些实施例中制作阵列基板的工艺简单，在相关技术中的设备中即可完成制作，无需对设备进行改造。
本公开的一些实施例仍以3840×2160分辨率的显示结构为例，其中，一个像素单元51包括四个亚像素单元。本公开的一些实施例中的四个亚像素单元呈横向一字排列或呈田字排列。当本公开的一些实施例中的四个亚像素单元呈横向一字排列时，其像素电极的具体设置与本公开的一些实施例相似，这里不再赘述。下面以本公开的一些实施例中的四个亚像素单元呈田字排列为例进行具体介绍。
如图8所示，本公开的一些实施例中每个亚像素单元的长边沿阵列基板的短边方向，每个亚像素单元的短边沿阵列基板的长边方向，即每个亚像素单元的短边沿阵列基板曲面弯曲方向。本公开的一些实施例中整个阵列基板中心轴左、右两侧各有2880列像素单元且关于中心轴呈对称分布，其中，2880列像素单元中，有1440列像素电极的狭缝呈尖括弧“＜”状，有1440列像素电极的狭缝呈尖括弧“＞”状，且不同结构的像素电极相互间隔排列。本公开的一些实施例中的阵列基板横向共有1080行像素单元，其中有540行的亚像素分别对应彩膜基板的R色阻层和B色阻层，有540行的亚像素分别对应彩膜基板的G色阻层和W色阻层，且与R色阻层和B色阻层对应的亚像素，和与G色阻层和W色阻层对应的亚像素隔行交错排布。可选地，本公开的一些实施例中位于同一列的像素单元中的像素电极的结构相同。
当然，本公开的一些实施例中也可以将位于中心轴53一侧同一行的像素单元中的像素电极的结构设计为相同，位于中心轴53另一侧同一行的像素单元中的像素电极的结构设计为相同。这种设计与本公开的一些实施例类似，这里不再赘述。
当本公开的一些实施例中的阵列基板与对盒设置的彩膜基板在外力作用下弯曲时，虽然对两种不同结构的像素电极组成的像素单元的透过率影响不同，但是由于阵列基板和彩膜基板组成的液晶显示面板中心轴左、右两侧的像素单元的数量相同，且关于中心轴呈对称分布，因此与相关技术相比，本公开的一些实施例中的彩膜基板的位移对液晶偏转和透光率的影响相同，仍能保持相同的透过率和亮度。
本公开的一些实施例还提供了一种曲面显示面板，包括阵列基板和对盒基板。阵列基板和对盒基板对盒后沿阵列基板的长轴延伸方向的截面为弧形截面，其中，阵列基板为本公开的一些实施例中提供的上述阵列基板。
本公开的一些实施例还提供了一种曲面显示装置，该曲面显示装置包括本公开的一些实施例提供的上述曲面显示面板。该曲面显示装置可以为液晶面板、液晶显示器、液晶电视、有机发光二极管(Organic Light Emitting Diode， OLED)面板、OLED显示器、OLED电视或电子纸等显示装置。
综上所述，本公开的一些实施例提供一种阵列基板，包括若干阵列排列的像素单元。每一像素单元包括至少两个亚像素单元，每一亚像素单元包括一像素电极和公共电极，其中，位于同一像素单元中的像素电极和/或公共电极的结构相同，位于不同像素单元中的像素电极或公共电极的结构至少包括第一种结构和第二种结构两种不同的结构。像素电极或公共电极以阵列基板的中心轴为轴对称设置。中心轴为位于阵列基板中心并沿平行于阵列基板的方向延伸的直线，且其在阵列基板弯曲后延伸方向不发生变化。当本公开的一些实施例中的阵列基板与对盒设置的彩膜基板在外力作用下弯曲时，由于本公开的一些实施例中位于同一像素单元中的像素电极或公共电极的结构相同，位于不同像素单元中的像素电极或公共电极的结构至少包括两种不同的结构，并且像素电极或公共电极以阵列基板的中心轴为轴对称设置，因此由阵列基板和彩膜基板组成的液晶显示面板中心轴左、右两侧的像素单元的数量相同，且关于中心轴呈对称分布。与相关技术中单一的像素电极结构的设计方式相比，本公开的一些实施例中的彩膜基板的位移对液晶偏转和透光率的影响相同，仍能保持相同的透过率和亮度，因此能够提高液晶显示面板的视觉效果和画质。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
