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.

Abstract: An electrode sheet disposed in a touch input device capable of detecting a pressure of a touch on a touch surface may be provided. The touch input device includes: a display module; a pressure electrode disposed under the display module; and a reference pressure electrode disposed under the display module. A distance between the pressure electrode and a reference potential layer is changed when the pressure is applied to the touch surface. A capacitance detected at the pressure electrode is changed according to the distance change. A magnitude of the pressure applied to the touch surface is calculated on the basis of a difference between a reference capacitance calculated from a capacitance detected at the reference pressure electrode and a detected capacitance calculated from the capacitance detected at the pressure electrode.

Abstract: An electrode sheet including an electrode layer and a support layer may be provided. The electrode layer includes a first electrode and a second electrode. The electrode sheet is used to detect a capacitance change between the first electrode and the second electrode, which is changed according to a relative distance change between the electrode layer and a reference potential layer disposed apart from the electrode sheet. The support layer is made of a material which is bent when a pressure is applied thereto and which is restored to its original state when the pressure is released therefrom.
