1. A touch pressure sensitivity correction method comprising:

  • defining a plurality of reference points on a touch sensor panel;

    generating a reference data for an electrical characteristic change amount sensed by applying the same pressure to the plurality of reference points;

    generating an interpolated data corresponding to an electrical characteristic change amount for a random point located between the plurality of reference points;

    calculating, on the basis of the reference data and the interpolated data, for each of the reference points and the random point, a correction factor for correcting a touch pressure sensitivity of a touch input device to a target value; and

    uniformly correcting the touch pressure sensitivity of the touch input device by applying the calculated correction factor to each corresponding point;

    wherein the generating an interpolated data comprises;

    creating a base profile on the basis of two or more profiles of the electrical characteristic change amount;

    generating a delta data by calculating a deviation between an electrical characteristic change amount of the base profile and an electrical characteristic change amount of the reference data, with respect to coordinates of the plurality of reference points; and

    calculating the electrical characteristic change amount for the random point on the basis of the delta data.
