<p>The present invention relates to a touch detection method and a touch detection apparatus. The touch detection apparatus according to one embodiment of the present invention can comprise: a plurality of sensor pads for outputting a signal according to a touch state of a touch input tool in response to an alternating voltage which alternates at a predetermined frequency in a floating state; a voltage fluctuation measurement unit for measuring a voltage fluctuation in the sensor pads depending on the alternating voltage when a touch is not generated, and measuring a voltage fluctuation in the sensor pads depending on the alternating voltage when a touch is generated; a touch capacitance acquisition unit for acquiring a touch capacitance on the basis of a predetermined variable being in a linear relation with the touch capacitance, and of mapping information mapped between the voltage fluctuations in the sensor pads when a touch is not generated and when a touch is generated; and a touch signal detection unit for calculating a touch area on the basis of the acquired touch capacitance.</p> |
