multipoint touch screen.To solve these problems, the biggest advantage of choosing the analog method is that it can analyze and improve the resolution of the touch screen, but the anti-interference ability is not as good as the pulse method. Although the pulse method is selected, although the anti-interference ability is strong, the pulse method requires a response process at the receiver The problem of time, but the touch screen requires extremely fast speed, so it is necessary to have technological breakthroughs in several aspects such as adaptive circuits, microcontroller software, mold design, selection of light-transmitting materials.
