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 touch input device detecting a touch position and a touch pressure includes a display module having a first layer made of glass or plastic and a second layer disposed under the first layer and made of glass or plastic; touch electrodes formed within the display module for detecting the touch position and the touch pressure; and a reference electrode disposed apart from the touch electrode. The touch position is detected by a sensing signal received from the touch electrode. An electrical signal changed by a capacitance between the touch electrode and the reference electrode is detected from the touch electrode. The capacitance is changed by change of a distance between the touch electrode and the reference electrode. The distance between the touch electrode and the reference electrode is changed by the bending of the display module. The touch pressure is detected based on the capacitance.

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.
