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.
