Description

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。
现有的On Cell式触控显示装置如图1所示，包括显示面板100、位于显示显示面板100上的触控层200、位于所述触控层200上的偏光层300、位于所述偏光层300上的保护膜400，其中，如图2所示，触控层200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，该触控层200将第一电极11’和 第二电极21’制作于同一膜层，容易导致第一电极11’和 第二电极21’短路及产生静电损伤风险，且第二电极21’需要通过另一膜层的第二连接线22’通过过孔30’连接，在连接时容易出现短路，且需要的光罩数量较多，制作繁琐。

需要说明的是，所述第一电极211及第一连接线212位于同一膜层，并通过一道图案化制程同时形成，所述第二电极221及第二连接线222位于同一膜层，并通过一道图案化制程同时形成，在本发明中制作触控电极（包括第一触控电极阵列和第二触控电极阵列）仅需要两到图案化制程，相应的光罩数量也只需要两个，相比于现有技术，需要的光罩数量明显减少，并且第一电极211和第二电极221位于不同膜层，两者之间有第一偏光片30绝缘，相比于现有技术，能够有效避免第一电极211和第二电极221之间发生短路，更进一步地，所述第二电极221与第二连接线222位于同膜层，并通过一道图案化制程同时形成，从而第二电极221与第二连接线222之间不需要再通过过孔连接，能够有效避免由过孔连接而带来的连接不良。
具体地，在本发明的第二实施例中，所述触控显示装置还包括位于所述第二触控电极阵列40上的保护膜70，
优选地，在本发明的第二实施例中，所述第一偏光片30通过光学透明胶贴附于所述第一触控电极阵列20上。
综上所述，本发明提供一种触控显示装置，包括显示面板、设于所述显示面板上的第一触控电极阵列、设于所述第一触控电极阵列上的第一偏光片及设于所述第一偏光片上的第二触控电极阵列，所述第一触控电极阵列通过所述第一偏光片与所述第二触控电极阵列绝缘分隔，通过将第一触控电极阵列和第二触控电极阵列分设于第一偏光片的两侧，能够避免第一触控电极阵列与第二触控电极阵列短路，防止触控不良，同时减少膜层数量，简化触控结构，降低产品厚度。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
