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: In one embodiment, a method for operating a camera included in a touch input device including a touch screen is disclosed. A processor determines a capacitance pattern for a varying capacitance throughout the touch screen when the touch screen is underwater and no touch input occurs. The processor resets a varying reference capacitance for determining whether a touch input by an object occurs or not, the varying reference capacitance being reset based on the determined capacitance pattern when the touch screen is underwater and no touch input occurs. The touch screen receives a touch pressure by the object underwater. Operation of the camera is controlled according to the touch pressure to the touch screen.
