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.
