触摸屏的发明大大方便了我们对一些电器的使用,其实触摸屏的原理用所学的初中物理串联电阻分压的知识就可以简单的解释.例(2011年大同杯物理竞赛)电阻式触摸屏将矩形区域中触摸点(X,Y)的物理位置转换为代表X坐标和Y坐标的电压.电阻式触摸屏有两层电阻,当未在触摸屏上施 Touch screen invention greatly facilitates our use of some electrical appliances, in fact, the principle of the touch screen with junior high school physics series resistor divider knowledge can simply explain. (2011 Datong Cup Physics Competition) Resistive touch screen The rectangular area The physical location of the touch point (X, Y) is converted to a voltage that represents the X and Y coordinates The resistive touch screen has two layers of resistance that, when not applied to the touch screen
