Description

一种防静电单层多点电容屏
技术领域
本发明属于电容屏技术领域,具体涉及一种防静电单层多点电容屏。
背景技术
电容屏在触控屏领域应用广泛,目前,电容屏更轻薄、更加灵敏以及边框更窄是发展的趋势。现有技术中的电容屏,其厚度以及边框控制均难以满足要求。中国发明专利:一种防静电电容屏,公开号204719725U,公开日2015年10月21日,公开了一种防静电电容屏,通过在触摸盖板与ITO玻璃的上下均设置防静电膜防静电,由于防静电膜具有一定厚度,两层防静电膜加在原有的屏幕上下,大大增加了屏幕的厚度。中国发明专利:防静电触摸屏,公开号201955762U,公开日2011年08月31日,公开了一种防静电触摸屏,在说明书附图中可以看出,其导电薄膜覆盖了屏幕面板的四周一部分,该种涉及增加了屏幕边框的宽度,亦不符合电容屏发展的趋势。
发明内容
本发明所要解决的技术问题是:提供一种电容屏,在防静电的同时,其厚度、边框宽度均比较小。
本本发明所采取的技术方案是:
一种防静电单层多点电容屏,包括盖板玻璃层,盖板玻璃层内侧设有ITO导电层,盖板玻璃层与ITO导电层的侧面设置一圈铜箔,铜箔通过导电银胶层与盖板玻璃层与ITO导电层的侧面相贴合;铜箔通过引线接地;所述的ITO导电层包含至少2组电极单元,每组电极单元均由一山形电极与一倒山形电极相插接而成,山形电极与倒山形电极通过引线连接触控IC。
进一步地,所述铜箔的宽度为盖板玻璃层与ITO导电层厚度之和。
本发明的有益效果是:本发明通过在单面单层ITO方案,将触摸屏厚度控制在最小,同时采用触摸屏侧面设置用于导静电的铜箔,不仅不会占用触摸屏触摸区域的面积,亦不增加触摸屏的厚度,实现触摸屏轻薄化与窄边框化。
附图说明
图1为所述一种防静电单层多点电容屏结构示意图;
图2为所述一种防静电单层多点电容屏ITO导电层图案结构。
具体实施方式
下面结合附图对本发明的具体实施方式进行详细说明。
如图1和图2所示的一种防静电单层多点电容屏,包括盖板玻璃层1,盖板玻璃层1内侧设有ITO导电层2,盖板玻璃层1与ITO导电层2的侧面设置一圈铜箔4,铜箔4通过导电银胶层3与盖板玻璃层1与ITO导电层2的侧面相贴合;铜箔4通过引线接地;所述的ITO导电层2包含至少2组电极单元,每组电极单元均由一山形电极21与一倒山形电极22相插接而成,山形电极21与倒山形电极22通过引线连接触控IC;所述铜箔4的宽度为盖板玻璃层1与ITO导电层2厚度之和。
当本发明所述的一种防静电单层多点电容屏用于智能电视、电脑显示屏时,其铜箔4通过引线连接PCB板的接地线,当本发明应用于手机等移动设备时,其铜箔4虽然无法实时接地,但可以通过手机充电座接地线,将静电导出,防止静电的累积;由于智能手机充电频繁,基本可以起到防静电的目的。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明的范围内。本发明要求保护范围由所附的权利要求书及其等同物界定。
