Product Details
Introduction
 
Touch sensitive, high-definition display
 
Projected capacitive touch screen for single and multi-touch
 
USB interface for easy connection
                                                                                             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.
