Abstract
A touch panel sensing circuit senses a voltage variation of a coupling capacitor formed between a first directional signal line and a second directional signal line separated from the first directional signal line by a dielectric when an object approaches. The sensing circuit eliminates the parasitic capacitance effect on the signal lines and rapidly accumulates charges for an amplifier in sensing to thereby increase the operational speed of the sensing circuit.
