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 change 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.
