触摸屏系统一般包括触摸屏控制器（卡）和触摸检测装置两个部分。其中，触摸屏控制器（卡）的主要作用是从触摸点检测装置上接收触摸信息CONTROLENGINEERINGChina版权所有，并将它转换成触点坐标，再送给CPU，它同时能接收CPU发来的命令并加以执行：触摸检测装置一般安装在显示器的前端，主要作用是检测用户的触摸位置，并传送给触摸屏控制卡。
工业触摸屏具有很强的灵活性，可以按照设计要求更换或增加功能模块，扩展性强，可以满足复杂的工艺控制过程，甚至可以直接通过网络系统和PLC通讯，大大方便了控制数据的处理与传输，减少了维护量。
电阻型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（小于千分之一英寸）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多少，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。
五线电阻触摸屏的外层导电层使用的是延展性好的镍金涂层材料，外导电层由于频繁触摸，使用延展性好的镍金材料目的是为了延长使用寿命，但是工艺成本较为高昂。镍金导电层虽然延展性好，但是只能作透明导体，不适合作为电阻触摸屏的工作面，因为它导电率高，而且金属不易做到厚度非常均匀，不宜作电压分布层，只能作为探层。
电阻型触摸屏是一种对外界完全隔离的工作环境，不怕灰尘和水汽，它可以用任何物体来触摸，可以用来写字画画，比较适合工业控制领域及办公室内使用。电阻型触摸屏共同的缺点是因为复合薄膜的外层采用塑胶材料，不知道的人太用力或使用锐器触摸可能划伤整个触摸屏而导致报废。不过，在限度之内，划伤只会伤及外导电层，外导电层的划伤对于五线电阻触摸屏来说没有关系，而对四线电阻触摸屏来说是致命的。
逻辑控制与通讯模块
逻辑控制模块包含24V直流输入（18-32）电源，SDRAM内存及CF闪存卡、10/100BaseT以太网端口、可用于文件传送,打印及与可编程控制器通讯的232串行端口、可用于连接鼠标，键盘或打印计的USB端口。内部电路板上内嵌了CPU处理芯片，负责显示屏的输入、输出以及通讯数据的处理工作。通讯模块负责特定的网络传输，以提高数据传输速率。
