红外式触摸屏 (电阻式、电容式触摸屏都属于接触式触摸屏，也就是说，感应触摸点的传感器部分和触摸笔直接接触的。这样的设计,至少在物理上、机械上增加了磨损等因素。而下面将要绍两种常见的非接触式触摸屏,也就是说，感应触摸点的传感器和触摸笔不是直接接触的。 4.超声波触摸屏 首先绍红外式触摸屏。红外式触摸屏是利用平面上横纵方向上布满了红外线矩阵来检测是否有触摸点， 超声波触摸屏透光度好，清晰度高，而且减少了像触摸笔和触摸屏那样的物理接触，减少了机械磨损，反应灵敏，不受温度、湿度等环境因素影响，分辨率高，寿命长（维护良好情况下5000万次）。目前在公共场所使用较多，但表面声波屏需要经常维护，因为灰尘，油污甚至饮料的液体沾污在屏的表面，都会阻塞触摸屏表面的导波槽，使波不能正常发射，或无常识别，从而影响触摸屏的正常使用，用户需严格注意环境卫生，保持屏面的光洁。
