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.

Abstract: In one embodiment, a touch sensor includes a first electrode, a second electrode, and a spacer layer located between the first electrode and the second electrode. One of the first electrode and the second electrode is a drive electrode to which a drive signal is applied. The other one of the first electrode and the second electrode is a receiving electrode that receives the drive signal by a mutual capacitance between the first electrode and the second electrode. When an external pressure is applied to the first electrode through a display, the first electrode is concavely bent toward the second electrode. The mutual capacitance between the first electrode and the second electrode changes according to a distance between the first electrode and the second electrode. The magnitude of the external pressure according to the change of the capacitance between the first electrode and the second electrode is detected.
