Abstract: A touch sensor panel may be provided that includes a plurality of drive electrodes formed in a first layer; and a plurality of receiving electrodes which are arranged to cross the plurality of drive electrodes and are formed in a second layer. In the plurality of drive electrodes, a column of drive electrodes is formed by connecting a plurality of lozenge-shaped unit electrodes in a column direction, and the drive electrodes of each column are disposed at a regular interval in a row direction. The plurality of receiving electrodes are composed of a line having a predetermined width and are arranged in the row direction in such a way as to pass through a center of the unit electrode. Through this, the touch sensor panel capable of linearly detecting the change of the capacitance is provided, so that touch position can be accurately detected.

Abstract: A touch input device may be provided that includes a display module; a substrate which is disposed under the display module; a pressure sensor which is disposed between the display module and the substrate; and a pressure sensing circuit which outputs a predetermined voltage. The touch input device detects the pressure magnitude on the basis of the voltage output from the pressure sensing circuit. The pressure sensing circuit includes a pressure sensing node NA; a switch serially connected between a power voltage VDDA and the pressure sensing node; a current source serially connected between the pressure sensing node and the ground; and an output node No. The current source is turned on during a first time period t1 every cycle. The switch is turned on every cycle during a third time period t3 separated from the first time period t1 by a predetermined time period.
