Capacitive touch screen type is divided into surface capacitive touch screen and projected capacitive touch screen two.

Surface capacitive touch screen

Commonly used surface capacitive touch screen, it works simple, low cost, the design of the circuit is simple, but difficult to achieve multi-touch.

Projected capacitive touch screen

Projected capacitive touch screen with multi-finger touch function. Both capacitive touch screens have the advantages of high light transmittance, fast response, long life, and the like. The disadvantages are as follows: as the temperature and humidity change, the capacitance value will change, resulting in poor stability of work and drift occasionally, Need to regularly proofread the screen, and can not wear ordinary gloves for touch positioning.
