电阻触摸屏的屏体部分是一块与显示器表面相匹配的多层复合薄膜，由一层玻璃或有机玻璃作为基层，表面涂有一层透明的导电层，上面再盖有一层外表面硬化处理、光滑防刮的塑料层，它的内表面也涂有一层透明导电层，在两层导电层之间有许多细小(小于千分英寸)的透明隔离点把它们隔开绝缘。
当手指触摸屏幕时，平常相互绝缘的两层导电层就在触摸点位置有了一个接触，因其中一面导电层接通Y轴方向的5V均匀电压场，使得侦测层的电压由零变为非零，这种接通状态被控制器侦测到后，进行A/D转换，并将得到的电压值与5V相比即可得到触摸点的Y轴坐标，同理得出X轴的坐标，这就是所有电阻技术触摸屏共同的基本原理。电阻类触摸屏的关键在于材料科技。电阻屏根据引出线数，分为四线、五线、六线等多线电阻触摸屏。电阻式触摸屏在强化玻璃表面分别涂上两层OTI透明氧化金属导电层，外面的一层OTI涂层作为导电体，第二层OTI则经过精密的网络附上横竖两个方向的+5V至0V的电压场，两层OTI之间以细小的透明隔离点隔开。当手指接触屏幕时，两层OTI导电层就会出现一个接触点，电脑同时检测电压及电流，计算出触摸的位置，反应速度为10-20ms。
