Abstract: A touch input device capable of detecting pressure of a touch on a touch surface may be provided. The touch input device includes: a display module including a display panel; a substrate which is disposed below the display module and is a reference potential layer; and one or more pressure electrodes which are formed on the display panel. The display panel includes electrodes used to drive the display panel. A drive signal Tx which is applied to the pressure electrode is simultaneously applied to one or more of the electrodes used to drive the display panel. A capacitance which is detected at the pressure electrode is changed by a distance change between the pressure electrode and the substrate due to the pressure applied to the touch surface. A magnitude of the pressure applied to the touch surface is calculated based on the detected capacitance calculated from the capacitance which is detected at the pressure electrode.

Abstract: In one embodiment, a touch sensor includes a first electrode, a second electrode, and a spacer layer located between the first electrode and the second electrode. One of the first electrode and the second electrode is a drive electrode to which a drive signal is applied. The other one of the first electrode and the second electrode is a receiving electrode that receives the drive signal by a mutual capacitance between the first electrode and the second electrode. When an external pressure is applied to the first electrode through a display, the first electrode is concavely bent toward the second electrode. The mutual capacitance between the first electrode and the second electrode changes according to a distance between the first electrode and the second electrode. The magnitude of the external pressure according to the change of the capacitance between the first electrode and the second electrode is detected.
