Abstract

一种触控基板及显示装置。该触控基板包括基底和设置在基底上的多行触控电极（1），任意两相邻的触控电极（1）的彼此相对的侧面均凹凸配合；该触控基板上还设置有多条信号线，且多条信号线设置在各个触控电极（1）之间的区域内。在依次对触控基板中各行触控电极（1）施加触控信号时，在任意两相邻的触控电极（1）的彼此相对的侧面之间形成的边缘电场可以将该位置处的液晶分子锁死而形成暗区，从而避免了在该位置处的液晶分子由于边缘电场的存在而导致的漏光现象；同时，由于信号线设置在相邻各行触控电极之间，因此不会影响触控基板的开口率。

Description

触控基板及显示装置 技术领域
本发明属于显示技术领域，具体涉及一种触控基板及显示装置。
背景技术
触摸屏因具有易操作性、直观性和灵活性等优点，已成为个人移动通讯设备和综合信息终端(如平板电脑、智能手机、超级笔记本电脑等)的主要人机交互手段。触摸屏根据不同的触控原理可分为电阻触摸屏、电容触摸屏、红外触摸屏和表面波(SAW)触摸屏这四种主要类型。电容触摸屏具有多点触控的功能，其反应时间短，使用寿命长并且透过率较高，用户使用体验优越。同时随着工艺的逐步成熟，电容触摸屏的良品率得到显著提高，价格日益降低，因此目前已成为中小尺寸信息终端触控交互的主要技术。
通常，如图1所示，触控面板上包括交叉设置的触控电极1和感应电极2，在触控阶段，依次向各个触控电极1施加触控信号，所以被施加触控信号的触控电极1与邻近的尚未施加触控信号的另一触控电极1上的电压不同，因此在这两个触控电极1之间会形成边缘电场，导致在形成有边缘电场的位置处的液晶发生无效偏转，从而导致触控面板出现漏光的现象。
发明内容
本发明所要解决的技术问题包括，针对现有的触控面板存在的上述问题，提供一种有效避免触控电极边缘电场导致漏光的触控基板及显示装置。
解决本发明技术问题所采用的技术方案包括一种触控基板， 包括基底和设置在基底上的多行触控电极，任意两相邻的所述触控电极的彼此相对的侧面凹凸配合；所述触控基板上还设置有多条信号线，且多条所述信号线设置在各个所述触控电极之间的区域内。
优选的是，所述信号线包括栅线和公共电极线中的至少一种。
优选的是，所述信号线的走线图案的形状与用于限定所述信号线的走线图案所在区域的两相邻的所述触控电极的相对侧面的形状相配合。
优选的是，所述触控基板还包括与多行所述触控电极交叉且绝缘设置的多列感应电极。
优选的是，每行所述触控电极均包括并排设置的多个触控子电极，并且所述触控基板上的所有触控子电极呈矩阵排列。
进一步优选的是，任意两相邻的所述触控子电极的彼此相对的侧面均为凹凸配合。
进一步优选的是，所述触控基板还包括多条数据线，其设置在相邻的各列所述触控子电极之间的区域内，所述数据线的走线图案的形状与用于限定所述数据线的走线图案所在区域的两相邻的所述触控子电极的相对侧面的形状相配合。
优选的是，任意两相邻的所述触控电极的彼此相对的侧面为锯齿形、S形、毛刺形中的任意一种。
优选的是，所述触控电极用于在显示阶段接收公共电极信号，在触控阶段接收触控信号。
优选的是，所述触控电极材料为透明导电材料。
进一步优选的是，所述透明导电材料为ITO。
解决本发明技术问题所采用的技术方案是一种显示装置，其包括上述的触控基板。
本发明具有如下有益效果：
在本发明的触控基板中，由于任意两相邻的所述触控电极的彼此相对的侧面均凹凸配合，因此在依次对各行触控电极施加触 控信号时，虽然在被施加触控信号的触控电极与邻近的未施加触控信号的触控电极之间仍然会形成边缘电场，但是此时所形成的边缘电场可以将边缘电场所在位置处的液晶分子锁死而形成暗区，从而避免了在该位置处的液晶分子由于边缘电场的存在而导致的漏光现象；同时，由于信号线设置在相邻的各行触控电极之间，因此不会影响所述触控基板的开口率。
附图说明
图1为现有的触控基板的示意图；
图2和图3为根据本发明的实施例的触控基板的平面图；
图4为根据本发明的另一实施例的触控基板的平面图。
其中附图标记为：1、触控电极；11、触控子电极；2、感应电极；3、栅线；4、数据线。
具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
参照图2和图3，本发明实施例提供一种触控基板，该触控基板可以用于互电容显示装置中，该触控基板包括基底以及交叉设置在基底上的多行触控电极1和多列感应电极2；任意两相邻的所述触控电极1的彼此相对的侧面凹凸配合；所述触控基板上还设置有多条信号线，且多条所述信号线设置在各个所述触控电极1之间的区域内。
在根据本发明实施例的触控基板中，由于任意两相邻的所述触控电极1的彼此相对的侧面均凹凸配合，因此在依次向各行触控电极1施加触控信号时，虽然在被施加触控信号的的触控电极1与邻近的未施加触控信号的触控电极1之间仍然会形成边缘电场，但是此时所形成的边缘电场可以将边缘电场所在位置处的液晶分 子锁死而形成暗区，从而避免了在该位置处的液晶分子由于边缘电场的存在而导致的漏光现象；同时，将信号线设置在各个所述触控电极1之间的区域(即，任意两行相邻的触控电极1的相对侧面限定的区域)内，从而不会影响所述触控基板的开口率。
其中，上述的信号线可以包括栅线和公共电极线中的至少一者。具体的，当该触控基板为阵列基板时，该触控基板包括交叉且绝缘设置的多条栅线3和多条数据线4，可以理解的是，通常将栅线3成行设置，并且数据线4成列设置，此时可以在任意两行相邻的触控电极1之间的区域内设置一条栅线3。同时，当阵列基板上还设置有公共电极以及用于为公共电极提供公共电极信号的公共电极线时，也可以将公共电极线设置在相邻的各行触控电极1之间的区域内，从而使得触控基板的开口率最大化。
优选的，信号线的走线图案的形状与用于限定该信号线所在区域的一对相邻的触控电极1的相对侧面的形状相配合。其中，从平面图来看，任意两相邻的触控电极1的相对的侧面的形状可以为锯齿形、S形、毛刺形中的任意一种，当然也可以是方波形，但是方波形的密集度要特别的高(即，“方波”的周期特别短)，才能达到很好的效果。此时，信号线的走线图案的形状则可以相应的设置成锯齿形、S形、毛刺形中的任意一种，当然，也可以是其他曲线形状，优选地设置成与触控电极1的侧面的形状相配合的曲线形状。
其中，上述的触控电极1采用透明导电材料，优选为氧化铟锡ITO，当然也不局限于这一种材料，也可以是其他透明的导电材料。感应电极2和触控电极1的材料可以相同。
图4为根据本发明的另一实施例的触控基板的平面图。如图4所示，该触控基板可以用于自电容显示装置中，该触控基板包括基底，以及设置在基底上的多行触控电极1，每行触控电极1包括多个并排设置的触控子电极11，其中所述触控基板1上的所有触控子电极呈矩阵排列，每个触控子电极11能够起到发送信号和接 收信号这两种作用，且在行方向或列方向上相邻的任意两个所述触控子电极11的彼此相对的侧面均凹凸配合。该触控基板上还设置有多条信号线，且多条所述信号线设置在各个触控子电极11之间的区域内。
在本实施例的触控基板中，由于在行方向或列方向上相邻的任意两个触控子电极11的彼此相对的侧面均凹凸配合，因此在依次对各行触控子电极11施加触控信号时，虽然在被施加触控信号的触控电极1与邻近的未施加触控信号的触控电极1之间仍然会形成边缘电场，但是此时所形成的边缘电场可以将边缘电场所在位置处的液晶分子锁死而形成暗区，从而避免了在该位置处的液晶分子由于边缘电场的存在而导致的漏光现象。
其中，上述的信号线可以包括栅线和公共电极线中的至少一者、以及数据线。具体的，当该触控基板为阵列基板时，该触控基板包括交叉且绝缘设置的多条栅线3和多条数据线4，可以理解的是，通常将栅线3成行设置，并且数据线4成列设置，此时可以在任意两行相邻的触控子电极11之间的区域(即，任意两行相邻的触控子电极1的相对侧面限定的区域)内设置一条栅线3。同时，当阵列基板上还设置有公共电极以及用于为公共电极提供公共电极信号的公共电极线时，也可以将公共电极线设置在相邻的各行触控子电极11之间的区域内，从而使得触控基板的开口率最大化。
优选的，信号线的走线图案的形状与用于限定该信号线所在区域的一对相邻的触控子电极11的相对侧面的形状相配合。其中，从平面图来看，任意两相邻的触控子电极11的相对的侧面的形状可以为锯齿形、S形、毛刺形中的任意一种，当然也可以是方波形，但是方波形的密集度要特别的高(即，“方波”的周期特别短)，才能达到很好的效果。此时，信号线的走线图案的形状则可以相应的设置成锯齿形、S形、毛刺形中的任意一种，当然，也可以是其他曲线形状，优选地设置成与触控子电极11的侧面的形状相配合的曲线形状。
在本实施例中，数据线4也可以按照类似于栅线3的方式而设置。具体的，在任意两列相邻的触控子电极11之间的区域内设置一条数据线4，该数据线4的走线图案的形状与用于限定其所在区域的一对相邻的触控子电极11的相对侧面的形状相配合，从而进一步的提高触控基板的开口率。当然，数据线4也可以是其他曲线形状。
其中，上述的触控子电极11采用透明导电材料，优选为氧化铟锡ITO，当然也不局限于这一种材料，也可以是其他透明的导电材料。感应电极2和触控电极1的材料可以相同。
其中，本实施例中的触控子电极11可以分时复用为公共电极和触控电极，也就是说，触控子电极11在显示阶段用作公共电极以接收公共电极信号，在触控阶段用作触控电极以接收触控信号。
本发明实施例还提供了一种显示装置，其包括上述实施例中描述的触控基板。
所述显示装置可以为液晶显示装置，例如液晶面板、电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本实施例中的显示装置具有较高的触控灵敏度。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
