The basic structure of multipoint capacitive screen is introduced
- Jul 18, 2018 -


Multipoint capacitive screen, is the basic structure of the basic structure of the organic glass substrate for a single, uniform forging respectively on internal and external surfaces of the organic glass on a layer of transparent conductive film, transparent conductive film on the surface of the outer respectively on the four corners of a narrow electrodes on cone.Its working principle is: when the finger touch capacitive touch screen, in working face through high frequency signal, at this point a finger and touch screen face form a coupling capacitance, the equivalent of a conductor, because work surface has high frequency signal, the fingers in touch points suck a little current, the small current respectively from touch screen on the four corners of the electrode, through the four electrodes with the finger to the four corners of the current line is proportional to the distance
