Abstract
A sensitivity compensation method of a touch input device sensing a touch pressure may be provided. The sensitivity compensation method includes: defining a plurality of reference points spaced apart from each other on a touch sensor panel; generating a reference data corresponding to a capacitance change amount sensed by applying a predetermined pressure to the plurality of reference points; generating, on the basis of the reference data, 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 generated reference data and interpolated data, with respect to the reference point and random point respectively, a compensation factor for compensating a sensitivity of the touch input device to a target value; and compensating uniformly for the sensitivity of the touch input device by applying the calculated compensation factor to each corresponding points.
