Abstract
In one embodiment, a touch input device capable of detecting a pressure of a touch on a touch surface is disclosed. The touch input device includes a substrate and a display module. A reference potential layer is disposed within the display module. The touch input device further comprises an electrode which is disposed at a position where a distance between the electrode and the reference potential layer changes according to the touch on the touch surface. The distance changes according to a magnitude of the pressure of the touch. Further, an electric signal depending on the distance is outputted from the electrode.
