Dorman触摸屏信息娱乐显示器599-942。该触摸屏使用压力传感来控制电阻。触摸屏的主要部分是与显示器表面相匹配的电阻薄膜屏幕。这是一种多层复合膜。它使用玻璃或硬塑料平板为基础层,且表面涂有一层透明的氧化金属导电层(透明导电电阻),覆盖着一层硬化,外表面光滑防刮的塑料层,它的内表面也涂有一层,用许多小的(小于1/1000英寸)透明隔离点将两个导电层隔开。当一个手指触摸屏幕时，两个导电层在触摸点接触，电阻发生变化，在X和Y方向产生一个信号，然后发送到触摸屏控制器。控制器检测到这个触点并计算(X, Y)的位置，然后按照模拟鼠标的方式进行操作。这是电阻式触摸屏技术的最基本原理。所以电阻式触摸屏可以用较硬的物体来操作。由于外层导电层经常被接触，使用延性镍金材料的目的是延长使用寿命，但工艺成本相对较高。 Although the nickel-gold conductive layer has good ductility, it can only be used as a transparent conductor. It is not suitable as a working surface of a resistive touch screen because of its high conductivity and the metal is not easy to achieve a very uniform thickness. It should not be used as a voltage distribution layer. It can only be used as a probe. Floor.
