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.
