The scanning bus is used for scanning a touch frame. The sensing bus interleaves with the scanning bus, and senses at least a touched location on the touch frame. The control unit is coupled to the scanning bus and the sensing bus 20′ for controlling them. The discharging circuit is coupled to the sensing bus or/and the scanning bus, and is controlled by the control unit for releasing the charges at the touched location or/and on the relevant path between the touched location and the buses. Thereby, by using a discharging circuit for releasing charges on the parasitic capacitor, the parasitic capacitance effect is avoided. Hence, the sensing accuracy of the touch panel is increased.
