Description

触控基板、显示面板及其显示装置
本申请要求于2019年12月03日提交中国专利局、申请号为201911221430.5、发明名称为“触控基板、显示面板及其显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及显示技术领域，具体涉及一种触控基板、显示面板及其显示装置。
 背景技术
随着科技日新月异，触控面板由于具有人机互动的特性，已被广泛应用于智慧型手机(smart phone)、卫星导航系统(GPS navigator system)、平板电脑(tablet PC)以及笔记型电脑(laptop PC)等电子产品上。传统互容式触控面板的触控感测元件系由多条驱动电极与多条感应电极所构成，且两者交错排列。为了避免两者产生电连接，驱动电极与感应电极系由两层导电层所形成。但透过两层导电层形成触控感测元件还需于其间设置第一绝缘层，以绝缘两者，因此在越来越薄的设计趋势中无疑限制了触控面板的厚度。为此目前已发展出单层结构的互容式触控感测元件。
 技术问题
传统单层结构的互容式触控感测元件系由感应电极以及驱动电极所构成，且每一条感应电极对应一个驱动电极设置，使每一个驱动电极与感应电极的不同部分形成一感测单元。虽然单层结构的触控感测元件可缩减触控面板的厚度，但触控设计均以单面架桥的方式进行设计触控图案，驱动电极或者感应电极需要通过金属桥进行连接导通，且需要在第一绝缘层上开孔，驱动电极与金属桥进行桥接，为保证导通效果，桥接位置的需要考虑对位公差，所以此位置的金属宽度大于其他位置，导致此处像素的发光与非桥接位置的亮度有差异，造成显示面板显示不均。

传统单层结构的互容式触控感测元件系由感应电极以及驱动电极所构成，且每一条感应电极对应一个驱动电极设置，使每一个驱动电极与感应电极的不同部分形成一感测单元。虽然单层结构的触控感测元件可缩减触控面板的厚度，但触控设计均以单面架桥的方式进行设计触控图案，驱动电极或者感应电极需要通过金属桥进行连接导通，且需要在第一绝缘层上开孔，驱动电极与金属桥进行桥接，为保证导通效果，桥接位置的需要考虑对位公差，所以此位置的金属宽度大于其他位置，导致此处像素的发光与非桥接位置的亮度有差异，造成显示面板显示不均。
基于此，本发明实施例提供一种触控基板、显示面板及其显示装置，以下分别进行详细说明。
首先，本发明实施例中提供一种触控基板，该触控基板包括触控区，触控基板包括第一电极层、第二电极层和第一绝缘层，第一绝缘层位于第一电极层和第二电极层之间，第一电极层和第二电极层位于触控区。
请参阅图1、图2，图1为本发明实施例中的触控基板的一个实施例结构侧视图，图2为本发明实施例中触控基板10的一个实施例结构俯视图，其中，该触控基板10包括触控区11，具体的，在触控基板10中，触控区是来实现触控功能的核心区域，触控基板10包括第一电极层101、第二电极层102和第一绝缘层103，第一绝缘层103位于第一电极层101和第二电极层102之间，第一电极层101和第二电极层102位于触控区，其中，第一绝缘层103可用来将第一电极层101和第二电极层102进行分层绝缘，具体的，本实施例中的第一绝缘层103所采用的材料可以为有机绝缘材料或者绝缘材料，例如第一绝缘层103材料为聚酯（PET），本实施对绝缘材料不作限定，具体的，本实施例中，第一电极层101和第二电极层102所采用的材料可以为金、银、铜、锂、钠、钾、镁、铝、锌及其组合，也可为导电金属材料氧化铟锡、掺铝氧化锌、掺锑氧化锡及其组合，例如第一电极层101所采用的材料为铝和银的合金，第二电极层102所采用的材料为掺铝氧化锌，本实施例对第一电极层101和第二电极层102所采用的材料不作限定，在本实施例中，第一电极层101和第二电极层102组成了矩阵式投射电容。
本发明实施例中通过提供一种触控基板10，相较于现有技术的单层结构的互容式触控感测元件，本实施例采用分层的方式，将其中的第一电极层101和第二电极层102分别设置于不同的两层，避免了现有金属桥接处导致的亮度不均的技术问题，从而提高了显示面板的显示效果。
在上述实施例的基础上，在本申请的另一个具体实施例中，第一电极层包括多个沿第一方向间隔排布的至少两个第一电极，其中，至少两个第一电极彼此绝缘，第二电极层包括多个沿第二方向间隔排布的至少两个第二电极，其中，至少两个第二电极彼此绝缘连接，第一方向与第二方向不平行。
本实施例中，第一电极层101包括多个沿第一方向100间隔排布的至少两个第一电极1011，其中，至少两个第一电极1011彼此绝缘，第二电极层102包括多个沿第二方向200间隔排布的至少两个第二电极1021，其中，至少两个第二电极1021彼此绝缘连接，第一方向与第二方向不平行，具体的，在触控基板10中，第一电极1011和第二电极1021交叉的地方将会形成电容，也即这两组电极分别构成了电容的两极。当手指触摸到电容屏时，影响了触摸点附近两个电极之间的耦合，从而改变了这两个电极之间的电容量。检测互电容大小时，横向的电极依次发出激励信号，纵向的所有电极同时接收信号, 这样可以得到所有横向和纵向电极交汇点的电容值大小，即整个触摸屏的二维平面的电容大小。根据触摸屏二维电容变化量数据，可以计算出每一个触摸点的坐标。因此，屏上即使有多个触摸点，也能计算出每个触摸点的真实坐标。
本实施例中，第一电极层101包括多个沿第一方向100间隔排布的至少两个第一电极1011，其中，至少两个第一电极1011彼此绝缘，第二电极层102包括多个沿第二方向200间隔排布的至少两个第二电极1021，其中，至少两个第二电极1021彼此绝缘连接，第一方向与第二方向不平行，具体的第一方向100可以为从左至右且向上倾斜45°方向，第二方向200可以为从上至下且向右倾斜45°方向。

本实施例中，第一网格单元1014为菱形或正方形，例如，当第一网格单元中的第一金属线的边长相等但是相邻的第一金属线的延长线的相交角度不为90°时，第一网格单元为菱形，本申请对第一网格单元的形状并不做限定。
本实施例采用避让像素的方式，第一网格单元中包裹4个子像素，4个子像素分别为1个蓝色子像素1015，1个红色子像素1016，2个绿色字像素1017，其中，蓝色子像素位于2个绿色子像素的上方，红色子像素位于2个绿色子像素的下方，第二网格单元包裹4个子像素，4个子像素分别为1个蓝色子像素，1个红色子像素，2个绿色字像素，其中，蓝色子像素位于2个绿色子像素的下方，红色子像素位于2个绿色子像素的上方，第二网格单元包裹4个子像素，其中，第一金属线上包括有多个弯折部1018，具体的，在相邻的蓝色子像素和红色子像素之间的第一金属线垂直于相邻的蓝色子像素和红色子像素的连线，在为直线分布的第一金属线上形成为弯折部，该弯折部是为了避让像素而形成的，弯折部分布在，网格单元的端点和相邻两个端点的中点处，使得第一金属线不会遮挡像素发光。
本实施例采用避让像素的方式，第一网格单元中包裹4个子像素，4个子像素分别为1个蓝色子像素，1个红色子像素，2个绿色字像素，其中，蓝色子像素位于2个绿色子像素的右方，红色子像素位于2个绿色子像素的左方，第二网格单元包裹4个子像素，4个子像素分别为1个蓝色子像素，1个红色子像素，2个绿色字像素，其中，蓝色子像素位于2个绿色子像素的左方，红色子像素位于2个绿色子像素的右方，第二网格单元包裹4个子像素，其中，第一金属线上包括有多个弯折部，具体的，在相邻的蓝色子像素和红色子像素之间的第一金属线垂直于相邻的蓝色子像素和红色子像素的连线，在为直线分布的第一金属线上形成为弯折部，该弯折部是为了避让像素而形成的，使得第一金属线不会遮挡像素发光。
本实施例中，第一电极1011为驱动电极、第二电极1021为感应电极；或第一电极1011为感应电极、第二电极1021为驱动电极。
