Description

触控电极及触控显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种触控电极及触控显示装置。
 背景技术
随着显示技术的发展，液晶显示器（Liquid Crystal Display，LCD）等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。
触控面板（Touch panel）提供了一种新的人机互动界面，其在使用上更直接、更人性化。将触控面板与平面显示装置整合在一起，形成触控显示装置，能够使平面显示装置具有触控功能，可通过手指、触控笔等执行输入，操作更加直观、简便。
触控显示面板依感应技术不同可分为电阻式、电容式、光学式、音波式四种，目前主流的触控技术为电容式，其中电容式又分为自电容式和互电容式，目前市场上的电容式触控显示面板为主要为互电容式，互电容的优点在于可实现多点触控。触控显示面板根据结构不同可划分为 ：触控电路覆盖于液晶盒上式（On Cell），触控电路内嵌在液晶盒内式（In Cell）、以及外挂式。其中，In Cell式具有成本低、超薄、和窄边框的优点，主要应用在高端触控产品中，但由于In cell式触控技术工艺难度较大，信号干扰等因素，其灵敏度较差。目前市场上应用最多的触控显示面板仍为外挂式，外挂式的优点在于灵敏度高，响应速度快，但缺点是成本高，产品超薄化受限制。On Cell式集成了外挂式和In cell式的优点，既能提高灵敏度又能降低面板厚度。
如图1所示，现有的触控电极一般包括平行间隔排列的多条第一电极链1’及平行间隔排列的且与第一电极链1’交叉绝缘的多条第二电极链2’；每一条第一电极链1’包括多个间隔排列的第一电极11’以及位于该第一电极链1’与第二电极链2’的交叉处的第一连接线12’，相邻的两个第一电极11’通过第一连接线12’电性连接；每一条第二电极链2’包括多个间隔排列的第二电极21’以及位于该第二电极链2’与第二电极链1’的交叉处的第二连接线22’，相邻的两个第二电极21’通过第二连接线22’电性连接，所述第二连接部22’与所述第一连接部12’绝缘；其中，所述第一电极11’、 第二电极21’及第一连接线12’位于同一膜层，所述第二连接线22’位于不同于第一连接线12’的另一膜层，且第二连接线22’所在膜层和第一连接线12’所在膜层之间具有绝缘层，第二连接线22’通过穿越绝缘层的过孔30’与第二电极21’电性连接，现有的触控电极存在以下问题：首先，相邻的第二电极21’之间的间隔距离较大，第二连接线22’的距离过长，在实际生产中第二连接线22’过长会导致连接位置发黑或者发亮，降低显示品质，其次相邻的第二电极21’之间通过单条长距离的第二连接线22’连接，在实际生产中容易出现第二连接线22’断线及静电击穿等不良，进而导致触控失灵。

优选地，每一个第二连接部 22 中的第一连接桥 221 及第二连接桥 222 的数量均为 1 个，当然本发明对此不作限制，必要时，所述每一个第二连接部 22 中的第一连接桥 221 及第二连接桥 222 的数量还可以均为 2 个，使得当 2 个第一连接桥 221 中的一个及 2 个第二连接桥 222 中的一个出现断线时，仍可通过剩余的第一连接桥 221 及第二连接桥 222 ，实现相邻的两个第二电极 21 之间的电性连接。
优选地，每一个第二连接部 22 中的第三连接桥 223 的数量为 2 个，所述 2 个第三连接桥 223 分设于所述连接岛 220 的两侧， 2 个第三连接桥 223 的设置，可以进一步地提升连接的稳定性，在其中一个第三连接桥 223 出现断线时，仍可通过另一个第三连接桥 223 实现连接。
进一步地，每相邻的一第一电极 11 和一第二电极 21 之间均形成有间隙，所述间隙内设有与所述第一电极 11 和第二电极 21 绝缘的置空电极 31 。
