Abstract: In one embodiment, a touch input device includes a touch screen and is configured to perform mutually different operations with respect to a first touch and a second touch on the touch screen. The first touch is maintained during a time period equal to or greater than a first time period, wherein the first touch is maintained at a pressure less than a first pressure within the first time period. The second touch has a time interval having a pressure greater than the first pressure within the first time period. The first pressure is controlled and set by an input to the touch screen.

Abstract: A touch input device may be provided that includes a cover layer including a display area and an input area; a display panel which is disposed under the display area; and a pressure sensing unit which is disposed under the display panel and is disposed at a position adjacent to the input area. The pressure sensing unit includes a pressure sensor. When a pressure is applied to the cover layer, the cover layer and the display panel are bent. Electrical characteristics of the pressure sensor change due to the bending of the cover layer and the display panel. When the pressure is applied to the input area, a magnitude of the pressure applied to the input area is detected by the electrical characteristics of the pressure sensor.

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.
