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 of a touch on a touch surface includes a display panel and an electrode disposed under the display panel. An electrical characteristic detected at the electrode is changed by the bending of the display panel. A magnitude of the pressure applied to the touch surface is detected according to the change amount of the electrical characteristic. The display panel includes a first area and a second area. A pressure detection sensitivity of the first area is higher than a pressure detection sensitivity of the second area. When the first area and the second are bent to the same degree, a chance amount of the electrical characteristic detected when a pressure is applied to the second area is greater than a change amount of the electrical characteristic detected when a pressure is applied to the second area.
