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: According to one embodiment, a touch input device includes a pressure detection module for detecting the touch pressure, and a reference potential layer provided under the pressure detection module. The reference potential layer is composed of at least one of a battery having a conductive material and a can receiving other components. Through this, the touch input device is capable of the most efficient detection of the touch pressure when various components provided in the touch input device are used as the reference potential layer, or when there are a plurality of the reference potential layers. In particular, when the plurality of reference potential layers having various forms and shapes are provided, the most efficient reference potential layer can be selected.
