根据传感器的类型，触摸屏大致被分为红外线式、电阻式、表面声波式和电容式触摸屏四种。红外线技术触摸屏价格低廉，但其外框易碎，容易产生光干扰，曲面情况下失真；电容技术触摸屏设计构思合理，但其图像失真问题很难得到根本解决；电阻技术触摸屏的定位准确，但其价格颇高，且怕刮易损；表面声波触摸屏解决了以往触摸屏的缺陷，清晰不容易被损坏，适于场合，缺点是屏幕表面如果有水滴和尘土会使触摸屏变得迟钝，甚至不工作。
红外线式触摸屏
红外线式触摸屏在显示器的前面安装一个电路板外框，电路板在屏幕四边排布红外发射管和红外接收管，一一对应形成横竖交叉的红外线矩阵。用户在触摸屏幕时，手指就会挡住经过该位置的横竖两条红外线，可以判断出触摸点在屏幕的位置。任何触摸物体都可改变触点上的红外线而实现触摸屏操作。
红外线式触摸屏特
红外式触摸屏不受电流、电压和静电干扰，适合某些恶劣的环境条件。其主要优点是价格低廉，安装方便，不要卡或任何其他控制器，可以用在档次上的计算机。由于没有电容充放电过程，响应速度比电容式快，但分辨率较低。
电阻式触摸屏
电阻屏外层一般使用的是软屏，通过按压使内触点上下相连。内层装有物理材料氧化金属，即N型氧化物半导体——氧化铟锡（IndiumTinOxides，ITO），也叫氧化铟，透光率为80%，上下各一层，中间隔开。ITO是电阻触摸屏及电容触摸屏都用到的主要材料，它们的工作面就是ITO涂层，用指尖或任何物体按压外层，使表面膜内凹变形，让内两层ITO相碰导电从而定位到按压点的坐标来实现操控。根据屏的引出线数，又分有4线、5线及多线。一般是不能多点触控，即只能支持单点，若按压两个或两个以上的触点，是不能被识别和找到坐标的。在电阻屏上要将一幅图片放大，就只能多次点击“+”，使图片逐步进阶式放大，这就是电阻屏的基本技术原理。
