Description
[technical field]
The utility model relates to a kind of touch-screen, particularly relates to a kind of condenser type nesa coating.
[background technology]
Capacitive touch screen utilizes the electric current induction of human body to carry out work, for example, when finger touch is on capacitive touch screen, due to people's bulk electric field, user and capacitance touch screen surfaces form with a coupling capacitance, for high-frequency current, electric capacity is direct conductor, so finger siphons away a very little electric current from contact point.This electric current divides from four electrodes on angle that are arranged in of capacitive touch screen and flows out, and the electric current of these four electrodes of flowing through is directly proportional to the distance of finger to four jiaos, and controller, by the accurate Calculation to these four current ratios, draws the position of touch point.
