手机已经从按键时代发展到触摸屏时代。触摸屏的工作原理是什么?在摔坏了2个手机屏幕的基础上,我对它产生了浓厚兴趣。目前手机的触摸屏多数是四线电阻式触摸屏。这种触摸屏是利用压力感应进行控制的,触点接触触摸屏的时候,处理器接受并经过运算转换为屏幕上的X、Y值,这样触摸点(X,Y)的物理位置转换 Mobile phone has been developed from the era of touch-screen touch screen era. What is the working principle of the touch screen? I broke the two cell phones on the basis of the screen, I have a strong interest in it. At present, most of the touch screen mobile phone is a four-wire resistive touch screen. The touch screen is controlled by pressure sensing. When the contact touches the touch screen, the processor accepts and converts the calculated values ​​into X, Y values ​​on the screen, so that the physical position of the touch point (X, Y)
