Abstract: In one embodiment, a touch input device capable of detecting a pressure of a touch on a touch surface is disclosed. The touch input device includes a substrate and a display module. A common voltage electrode is disposed within the display module. The touch input device further comprises an electrode which is disposed at a position where a distance between the electrode and the common voltage electrode changes according to the touch on the touch surface. The distance changes according to a magnitude of the pressure of the touch. Further, an electric signal depending on the distance is outputted from the electrode.

Abstract: A touch input device includes an organic light emitting display module; a pressure sensor including a pressure electrode outputting a first sensing signal for detecting a touch pressure and which is attached under the organic light emitting display module; a touch sensor including drive electrodes to which a driving signal is applied and receiving electrodes outputting a second sensing signal for detecting a touch position; and a substrate located under the organic light emitting display module. The substrate is spaced apart from the organic light emitting display module and includes a reference potential layer. A controller detects a magnitude of the touch pressure based on the first sensing signal. The organic light emitting display module is bent by the touch pressure. A distance between the pressure electrode and the reference potential layer is changed according to a bending of the organic light emitting display module.

Abstract: A touch input device includes a display module, a substrate for blocking electrical noise or for separating the display module from a circuit board or battery for operation of the touch input device, and a first electrode disposed on the display module and a second electrode disposed on the substrate. A spacer layer is disposed between the first electrode and the second electrode. A pressure magnitude of the touch is detected based on a capacitance between the first electrode and the second electrode. The capacitance is changed depending on the distance between the first electrode and the second electrode. The display module is bent by the touch, and the distance between the first electrode and the second electrode is changed due to the bending of the display module. The first electrode is disposed on a bendable surface of the display module.
