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: 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.
