Description:
GreenTouch G+G projected capacitive touch technology is with fast and sensitive response, the design with frame (without frame is optional) makes it looks professional and generous. The G+G model is designed for high-intensity and high-frequency business environments.

   Operation principle:
The surface of the capacitive screen is coated with a transparent conductive layer ITO, the voltage is connected to the four corners, and the electric charge is distributed on the surface of the screen to form a uniform electric field. When the screen is touched by the hand, the human body acts as a pole of the coupling capacitor, and the current is collected from the four corners of the screen to form another coupling capacitor. The pole, the controller calculates the relative distance of the current to the touch position to obtain the coordinate value at the touch.

   电容包装.jpg    Product packaging:
The 12.1-inch capacitive screen is divided into two inner and outer packagings, the inner layer is EPE foam and the outer layer is a traditional cardboard box. Put the touch screen into the corresponding EPE foam, and each touch screen corresponds to each EPE grid. Then put the EPE into the corresponding carton. Each size of the touch screen corresponds to each size of the package, this figure is for reference only.
