    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 touch input device capable of detecting a pressure of a touch on a touch surface may be provided that 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. According to the embodiment of the present invention, it is possible to provide a pressure sensor for pressure detection, a touch input device including the same, and a pressure detection method using the same. In addition, according to the embodiment of the present invention, it is possible to provide the pressure sensor having a high-pressure detection accuracy of the touch and the touch input device including 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: 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.
