Description

一种具有防静电功能的电阻式触摸屏 技术领域
本发明涉及电容式触摸屏技术领域，具体为一种具有防静电功能的电阻式触摸屏。
背景技术
电容式触摸屏技术是利用人体的电流感应进行工作的。电容式触摸屏是一块四层复合玻璃屏，玻璃屏的内表面和夹层各涂有一层ITO，最外层是一薄层矽土玻璃保护层，夹层ITO涂层作为工作面，四个角上引出四个电极，内层ITO为屏蔽层以保证良好的工作环境。当手指触摸在金属层上时，由于人体电场，用户和触摸屏表面形成以一个耦合电容，对于高频电流来说，电容是直接导体，于是手指从接触点吸走一个很小的电流。这个电流分别从触摸屏的四角上的电极中流出，并且流经这四个电极的电流与手指到四角的距离成正比，控制器通过对这四个电流比例的精确计算，得出触摸点的位置。
在使用电容式触摸屏的过程中，由于屏幕与外界的摩擦，特别是纺织类如：尼龙等，容易产生静电，高压静电容易对屏幕表面及屏幕底层的电路结构造成破坏。
发明内容
本发明的目的在于提供一种具有防静电功能的电阻式触摸屏，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种具有防静电功能的电阻式触摸屏，包括背板，所述背板的顶端设置有间隔层，所述间隔层的顶端设置有上面板，所述上面板的顶端设置有抗静电层，所述抗静电层的表面设置有银导线，所述底座的两侧通过触头电极固定连接有支座的一端，所述支座的另一端通过连接板与银导线的两端固定连接，所述底座和支座的夹缝处涂有绝缘层。
优选的，所述触头电极为L型结构，所述触头电极的材质为紫铜，所述触头电极的表面镀银。
优选的，所述连接板的底端贯穿于支座，所述支座的底端与触头电极的一端固定连接。

优选的，所述银导线等间距分布在抗静电层的表面，所述银导线的直径为0.01MM。
优选的，所述支座与底座相互垂直，所述底座的材质为钛合金。
与现有技术相比，本发明的有益效果是：该种发明设计合理，使用方便，通过设置有相互垂直的支座与底座，保护了电阻式触摸屏，提高了防护效果，通过设置有耐高温聚酯材料的抗静电层，且抗静电层的表面涂有离子型表面活性剂，提高了抗静电效果，通过设置有银导线，有效的将静电吸附，提高了抗静电效果，该发明生产成本低廉，使用方便，简单方便，适合广泛推广。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-3，本发明提供一种技术方案：一种具有防静电功能的电阻式触摸屏，包括背板2，所述背板2的顶端设置有间隔层3，所述间隔层3的顶端设置有上面板4，所述上面板4的顶端设置有抗静电层5，所述抗静电层5的表面设置有银导线9，所述底座1的两侧通过触头电极10固定连接有支座7的一端，所述支座7的另一端通过连接板6与银导线9的两端固定连接，所述底座1和支座7的夹缝处涂有绝缘层8。
所述触头电极10为L型结构，所述触头电极10的材质为紫铜，所述触头电极10的表面镀银，所述连接板6的底端贯穿于支座7，所述支座7的底端与触头电极10的一端固定连接，所述抗静电层5的材质为耐高温聚酯，所述抗静电层5的表面涂有离子型表面活性剂，提高了抗静电效果，所述银导线9等间距分布在抗静电层5的表面，所述银导线9的直径为0.01MM，所述支座7与底座1相互垂直，所述底座1的材质为钛合金。
