Abstract: According to one embodiment of the present invention, a touch detection apparatus for a touch panel, including a plurality of sensor pads and signal wires connected to the plurality of sensor pads, respectively, is provided. The touch detection apparatus comprises a parasitic capacitance control unit for controlling the parasitic capacitance generated between a specific sensor pad which is to be an object of touch detection from among the plurality of sensor pads and another adjacent sensor pad. The parasitic capacitance control unit enables the output voltage of the specific sensor pad to be applied to another sensor pad connected to the signal wire that is adjacent to the signal wire of the specific sensor pad.
