Abstract: A touch input device capable of detecting a pressure of a touch on a touch surface may be provided. The touch input device includes: a display module; and a pressure sensor which is disposed at a position where a distance between the pressure sensor and a reference potential layer is changeable according to the touch on the touch surface. The distance is changeable according to a pressure magnitude of the touch. The pressure sensor outputs a signal including information on a capacitance which is changed according to the distance. The pressure sensor includes a plurality of electrodes to form a plurality of channels. The pressure magnitude of the touch is detected on the basis of a change amount of the capacitance detected in each of the channels and an SNR improvement scaling factor assigned to each of the channels.

Abstract: A method for correcting a touch pressure sensitivity may be provided that includes: a modeling profile data generation step of generating modeling profile data on the basis of a plurality of collected profile data; and a set profile data generation step of generating set profile data on the basis of the modeling profile data and a reference data of a predetermined touch input device. As a result, it is possible to correct the touch pressure sensitivity of a predetermined touch input device such that the touch pressure is sensed with a uniform sensitivity on the entire display surface of the touch input device.
