红外线技术触摸屏（Infrared Touch Screen Technology）由装在[[触摸屏]]外框上的红外线发射与接收感测元件构成，在屏幕表面上，形成[[红外线探测网]]，任何触摸物体可改变触点上的红外线而实现触摸屏操作。红外线式触控屏的实现原理与表面声波式触控相似，它使用的是红外线发射与接收感测元件。这些元件在屏幕表面形成红外线探测网，触控操作的物体（比如手指）可以改变触点的[[红外线]]，进而被转化成触控的坐标位置而实现操作的响应。在红外线式触控屏上，屏幕的四边排布的电路板装置有[[红外发射管]]和[[红外接收管]]，对应形成横竖交叉的[[红外线矩阵]]。

*中文名:[[红外线技术触摸屏]]

*外文名:Infrared Touch Screen Technology

*原    理:横竖交叉的红外线矩阵

*优    点:任何可阻挡光线的物体来触摸

*最早出现时间:1992年
