Operation Principle:
Capacitive touch panel works through body’ current induction. When finger is on or close to touch

panel surface, due to body electric field, the user and touch panel surface forms one coupling capacitance. For high frequency current, capacitance is direct conductor, then fingers suck a small current from the contact point, through amplifying and accurately calculating this current signal, the controller works out the touch point position.
