Description

一种光学触摸屏
技术领域
本实用新型涉及一种光学触摸屏，具体地说是一种在作两点触摸画圆弧时出错机率为零的光学触摸屏。
背景技术
触摸屏作为一种便捷、直观的人机交互设备被广大人们所认可，市面上的触摸屏多种多样，带摄像头与反光镜触摸屏就是其中的一种。带摄像头与反光镜触摸屏通过检测触摸物及触摸物在反光镜中像的坐标来确定触摸物的位置，结构简单，成本低廉，易于制造。现有触摸屏在作两点触摸时画圆弧时易出错。
发明内容
本实用新型的目的是提供一种在作两点触摸画圆弧时出错机率为零的光学触摸屏。
本实用新型的目的通过以下技术方案来实现。
一种光学触摸屏，其特征在于：所述光学触摸屏包括框架、一钢化玻璃板、四条导光柱与四条电子连接线，钢化玻璃板安装在框架上，四条导光柱与四条电子连接线设置在钢化玻璃板上。
所述钢化玻璃板上设有三个CAMERA摸组与一个dummy模组，模组上集成了两个红外线LED灯。
本实用新型与现有技术相比具有以下优点。
本实用新型在作两点触摸画圆弧时出错机率为零。
附图说明
图1为本实用新型光学触摸屏的主视图。
具体实施方式
下面结合附图对本实用新型光学触摸屏作进一步详细描述。
如图1所示，本实用新型所述光学触摸屏包括框架1、一钢化玻璃板2、四条导光柱3与四条电子连接线，钢化玻璃板安装在框架上，四条导光柱与四条电子连接线设置在钢化玻璃板上。
本实用新型光学触摸屏包括三个CAMERA摸组，一个dummy模组，其中一个为主控摸组，其两个为SEVER模组，每个模组上集成了两个红外LED灯共八只红外LED，模组都为软板作成。其工作原理是通过摄相头4捕捉导光条上的明暗点，确定触点在屏上的位置，当使用两个摄相头时使用两点在屏上会形成虚点结果使定位出错，如加第三个摄相头后能纠正这一错误。
