specification |
The principle of XIETOUCH capacitive screen is to use the surface to project electrostatic charge. When a conductor (such as a finger) touches the surface of the screen, the surface contact point is electrostatically led to generate coordinates. Therefore, the capacitive screen function design has a transmitting source and a receiving source, that is, TX. With RX. The capacitive screens on the existing market are collectively referred to as projected surface capacitive screens.
