电阻式触控屏幕在工作时每次只能判断一个触控点，如果触控点在两个以上，就不能做出正确的判断了，所以电阻式触摸屏仅适用于点击、拖拽等一些简单动作的判断。而电容式触摸屏的多点触控，则可以将用户的触摸分解为采集多点信号及判断信号意义两个工作，完成对复杂动作的判断。
使用两根手指的拉伸、换位即可在屏幕上完成诸如放大、旋转这样趣味十足的操作，这在电容式触摸屏出现之前，几乎是不可想象的。
其实触摸屏的实现原理大致相同，都是在普通液晶屏上增加透明的触控面板。而我们所说的电阻式及电容式等类型，则是根据其工作原理的不同而划分的。目前触摸屏的分类主要有电阻式、电容式、红外线式、表面声波四种类型。在实际生活中我们接触多的还是电阻式触摸屏，它已经被广泛的应用在手机和随身数码产品当中。
