Description

液晶显示器及其阵列基板
技术领域
本发明涉及液晶显示技术领域，具体而言涉及一种液晶显示器及其阵列基板。
背景技术
传统的像素结构设计中，数据线通过薄膜晶体管与其相邻的像素电极电连接，并为其提供灰阶电压。由于薄膜晶体管沿数据线的延伸方向上所占的元件排布空间较大，为保证像素开口率，位于相邻两条数据线之间的两个像素开口区无法沿扫描线的延伸方向平行设置。然而这种设置会降低RGB掩膜板的共用性，增加像素电极的制造成本，并且像素开口区容易与液晶显示器的光学膜片发生光学干涉，降低液晶显示器的显示品质。如果保持两个像素开口区沿扫描线的延伸方向平行设置，必须缩小开口区的面积，则会降低像素开口率。
发明内容
本发明实施例提供一种液晶显示器及其阵列基板，能够确保液晶显示器的显示品质，并提高像素开口率。
本发明采用的一个技术方案是：提供一种阵列基板，包括：第一数据线和第二数据线，第一数据线和第二数据线沿第一方向延伸且沿垂直于第一方向的第二方向间隔设置；第一像素电极和第二像素电极，第一像素电极和第二像素电极设置于第一数据线和第二数据线之间，且沿第二方向间隔设置，第一像素电极与第一数据线相邻设置，第二像素电极与第二数据线相邻设置，第一数据线为第二像素电极提供灰阶电压，第二数据线为第一像素电极提供灰阶电压。
其中，阵列基板包括设置于第一数据线和第二数据线之间的第一薄膜晶体管和第二薄膜晶体管，第一数据线与第一薄膜晶体管的源极和漏极中的一者电连接，第二像素电极与第一薄膜晶体管的源极和漏极中的另一者电连接，第二数据线与第二薄膜晶体管的源极和漏极中的一者电连接，第一像素电极与第二薄膜晶体管的源极和漏极中的另一者电连接。
其中，第一薄膜晶体管和第二薄膜晶体管沿第一方向间隔设置于第一像素电极和第二像素电极的相对两侧。
其中，第一像素电极和第二像素电极沿第二方向平齐设置。
其中，第一像素电极和第二像素电极上分别设置第一开口区和第二开口区，第一开口区和第二开口区沿第二方向平齐设置。
其中，阵列基板进一步包括第一扫描线和第二扫描线，第一扫描线和第二扫描线沿第二方向延伸且第一方向间隔设置，第一像素电极、第二像素电极、第一薄膜晶体管和第二薄膜晶体管进一步位于第一扫描线和第二扫描线之间，第一扫描线与第一薄膜晶体管相邻设置，且与第一薄膜晶体管的栅极电连接，第二扫描线与第二薄膜晶体管相邻设置，且与第二薄膜晶体管的栅极电连接。
其中，阵列基板上进一步设置第一过孔和第二过孔，第二像素电极经第一过孔与第一薄膜晶体管的源极和漏极中的另一者电连接，第一像素电极经第二过孔与第二薄膜晶体管的源极和漏极中的另一者电连接。
其中，第一过孔和第一薄膜晶体管沿第二方向间隔设置，第二过孔和第二薄膜晶体管沿第二方向间隔设置。
其中，第一过孔和第一薄膜晶体管沿第二方向设置于同一直线上，第二过孔和第二薄膜晶体管沿第二方向设置于同一直线上。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种液晶显示器，包括上述阵列面板。
通过上述技术方案，本发明实施例产生的有益效果是：本发明实施例的阵列基板，设计第一数据线和第二数据线沿第一方向延伸且沿垂直于第一方向的第二方向间隔设置，第一像素电极和第二像素电极设置于第一数据线和第二数据线之间且沿第二方向间隔设置，第一像素电极与第一数据线相邻设置，第二像素电极与第二数据线相邻设置，通过第一数据线为第二像素电极提供灰阶电压，第二数据线为第一像素电极提供灰阶电压，增加沿数据线的延伸方向上的元件排布空间，使得与像素电极连接的元件沿扫描线的延伸方向能够水平设置，并且使得位于相邻两条数据线之间的两个像素开口区可以沿扫描线的延伸方向平行设置，从而能够确保液晶显示器的显示品质，并提高像素开口率。

并且，第一像素电极Pn-1、第二像素电极Pn、第一薄膜晶体管T1和第二薄膜晶体管T2进一步位于第一扫描线Gn-1和第二扫描线Gn之间，第一扫描线Gn-1与第一薄膜晶体管T1相邻设置，且与第一薄膜晶体管T1的栅极g1电连接，第二扫描线Gn与第二薄膜晶体管T2相邻设置，且与第二薄膜晶体管T2的栅极g2电连接。
另外，第一数据线Sn-1与第一薄膜晶体管T1的源极s1电连接，第二像素电极Pn与第一薄膜晶体管T1的漏极d1电连接，第二数据线Sn与第二薄膜晶体管T2的源极s2电连接，第一像素电极Pn-1与第二薄膜晶体管T2的漏极d2电连接。
图3是本发明具有图2所示像素结构的阵列基板的局部示意图。结合图3所示，第一像素电极Pn-1和第二像素电极Pn上分别设置第一开口区31和第二开口区32，第一开口区31和第二开口区32沿第二方向D2平齐设置。阵列基板11上进一步设置第一过孔33和第二过孔34，第一过孔33和第一薄膜晶体管T1沿第二方向D2间隔设置，第二过孔34和第二薄膜晶体管T2沿第二方向D2间隔设置，第二像素电极Pn经第一过孔33与第一薄膜晶体管T1的漏极d1电连接，第一像素电极Pn-1经第二过孔34与第二薄膜晶体管T2的漏极d2电连接。
在其它实施例中，第一数据线Sn-1可以与第一薄膜晶体管T1的漏极d1电连接，第二像素电极Pn与第一薄膜晶体管T1的源极s1电连接，第二数据线Sn与第二薄膜晶体管T2的漏极d2电连接，第一像素电极Pn-1与第二薄膜晶体管T2的源极s2电连接。此时，第二像素电极Pn经第一过孔33与第一薄膜晶体管T1的源极s1电连接，第一像素电极Pn-1经第二过孔34与第二薄膜晶体管T2的源极s2电连接。
本发明实施例能够增加沿数据线的延伸方向上的元件排布空间，例如第一数据线Sn-1与第二像素电极Pn之间沿第二方向D2上的元件排布空间，使得第一过孔33和第一薄膜晶体管T1沿第二方向D2设置于同一直线上，第二过孔34和第二薄膜晶体管T2沿第二方向D2设置于同一直线上，并且第一开口区31和第二开口区32位于同一直线上，在确保液晶显示面板10的显示品质的同时，可提高像素开口率。
本发明实施例还提供一种液晶显示器，包括权利要求图1所述实施例的液晶显示面板10，当然也包括具有图2和图3所述实施例的像素结构的阵列基板11，因此具有与其相同的技术效果。
再次说明，以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，例如各实施例之间技术特征的相互结合，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
