Abstract: A device according to the embodiment of the present invention includes a display; a touch sensing unit; a pressure sensing unit capable of sensing a magnitude of a pressure at the touched position; and a control unit. The control unit performs a control operation when a pressure touch is sensed and a swipe gesture in which a touch point is moved is sensed and then the swipe gesture ends. The control operation may be one of termination of running applications, changing into a one-hand keyboard mode, deletion or transmission of an object, and movement of the object. According to the embodiment of the present invention, the operability of the device is enhanced. According to the embodiment, it is possible to easily terminate running applications by using one finger even without using a separate home button.

Abstract: In one embodiment, a control method for a touch sensor panel is disclosed. The method includes obtaining touch information on the touch sensor panel from which an electrical signal outputted is changed according to a touch, and detecting at least one valid touch from the touch information. It is determined that a valid touch of the at least one valid touch is included in a palm touch group by (a) detecting a palm touch, which meets a palm touch condition, among the at least one valid touch, and (b) determining that the detected palm touch and the valid touch occur within a predetermined time period. A display unit displays an input corresponding to each of the at least one valid touch other than the valid touch included in the palm touch group.

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.
