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 panel; a substrate disposed under the display panel; and a pressure sensing unit. The pressure sensing unit includes a pressure sensor and a reference pressure sensor. When a pressure is applied to the touch surface, the display panel is bent. Electrical characteristics detected at the pressure sensor change by the bending of the display panel. A magnitude of the pressure applied to the touch surface is calculated based on a difference between a reference electrical characteristic calculated from electrical characteristics detected at the reference pressure sensor and the detected electrical characteristic calculated from the electrical characteristics detected at the pressure sensor.

Abstract: A sensitivity compensation method of a touch input device sensing a touch pressure may be provided. The sensitivity compensation method includes: detecting a capacitance change amount by applying a pressure to a plurality of points defined on a touch sensor panel; generating a raw data for the capacitance change amount of the defined point; generating a decimal value data for each of the sets by dividing a data value within the set by a maximum value within the set; calculating an average value of each defined point; generating a representative value data by calculating a value corresponding to all the points of the touch sensor panel; calculating a balance factor on the basis of the representative value data; and compensating for a touch pressure sensitivity of the touch input device by using the balance factor.

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.
