Description

液晶触控屏及其制造方法 技术领域
本发明关于显示技术领域,更具体而言是关于一种液晶触控屏及其制造方法,用以增加触控的灵敏度、降低成本并且降低液晶触控屏的重量和厚度。
背景技术
液晶电容触摸屏2是由液晶屏(liquid crystal display, LCD)21和电容触控屏22组合而成。所述液晶屏21由偏光片10、60、滤光片50、玻璃基板20、40和液晶层30组成,其示意性结构图如图1和图3所示,所述触控屏(touch panel, TP)22具有两层导电极板70、80,所述导电极板70、80是由膜材用激光镭射的方式蚀刻出不同的图案而形成。所述两层导电极板70、80分别为驱动电极和接收电极。在外面再加一个上盖玻璃或上盖膜层作为保护膜层90,最终采用全贴合或框贴合的方式贴合在偏光片60上,其示意性结构图,如图2和图3所示。
目前市场上的电容触控屏22结构为两层导电极板70、80加外一层上盖膜层90而形成。由公式C=ES/4πD知,当距离D越大,电容C越小,也即当手指接触时触控屏22时,感应到的电容量越小。且增设上盖膜层90的触控屏22比较厚重,成本比较高,对于追求轻薄低成本的消费者很难接受高成本且厚重的触控屏22导入市场。
