Abstract:
A touch detecting device comprises at least one driving circuit, a plurality of conductive lines and at least one sensing circuit. The originally available conductive lines of a touch panel are used to detect a finger touch by means of detecting a current leakage through the finger to the ground. Thus, the invention can reduce the hardware cost, avoid noise interference and correctly respond to a finger touch.
