Abstract
A touch pressure sensitivity correction method may be provided that includes: defining a plurality of reference points on a touch sensor panel; generating a reference data for a capacitance change amount sensed by applying the same pressure to the plurality of reference points; generating an interpolated data corresponding to a capacitance change amount for a random point present between the plurality of reference points; calculating, on the basis of the reference data and interpolated data, with respect to the reference points and the random point respectively, a correction factor for correcting a sensitivity of a touch input device to a target value; and correcting uniformly for the touch pressure sensitivity of the touch input device by applying the calculated correction factor to each corresponding point.
