Abstract
A touch panel apparatus includes: a data determination part determining whether a measurement value of a capacitance for each of a plurality of drive pulses measured by a sensing part is normal or abnormal; and a coordinate detection part outputting a touch coordinate position of a touch performed by an indication body in accordance with the measurement value of the capacitance which is determined to be normal by the data determination part, wherein the drive part changes a frequency of a drive pulse in the plurality of drive pulses corresponding to the measurement value of the capacitance which is determined to be abnormal by the data determination part, and outputs, in a subsequent scan, a plurality of drive pulses including a drive pulse whose frequency has been changed.
