    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.

    Abstract: A touch input device may be provided that includes: a cover; a display module disposed under the cover; and a pressure sensing unit disposed under the display module. The pressure sensing unit includes a first elastic foam, a pressure sensor disposed on the first elastic foam, and a first adhesive layer disposed between the first elastic foam and the pressure sensor. A change amount of a stress of the first elastic foam required for the first elastic foam to be compressed to half of the thickness thereof from its original state is less than the change amount of the stress of the first elastic foam required for the first elastic foam to be compressed from half of the thickness thereof to the thickness to which the first elastic foam is able to be maximally compressed.

    Abstract: Disclosed is a touch detector which detects a touch on a touch sensor panel including a plurality of first electrodes, a plurality of second electrodes and a plurality of third electrodes. The touch detector includes: a driving signal supplier which applies a driving signal to the plurality of first electrodes; and a sensing unit which receives a first signal including information on a capacitance changing depending on the touch on a touch surface of the touch sensor panel from the plurality of second electrodes. The sensing unit detects a touch pressure and a touch position on the touch surface of the touch sensor panel.

    Abstract: In one embodiment, a touch input device capable of detecting a pressure and a position of a touch on a touch surface is disclosed. The touch input device includes a cover layer of glass, a display panel, and a touch sensor panel fully laminated on the display panel. The device further includes a substrate spaced apart from the display panel and separating the display panel from a circuit board and a battery for operation of the touch input device, and a pressure electrode disposed between the display panel and the substrate. Drive electrodes are formed on one side of an insulation layer, and receiving electrodes are formed on the other side of the insulation layer. Further, a distance between the substrate and the display panel is maintained by a double adhesive tape formed on edge portions of the substrate and the display panel when no pressure is applied.
