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 and a method for measuring a capacitance of the touch input device may be provided. The touch input device includes: a display panel; a pressure sensor which is disposed under the display panel; a reference potential layer which is disposed apart from the pressure sensor; and a controller which receives an output voltage from the pressure sensor and calculates a first capacitance value, and calculates a second capacitance value by removing a parasitic capacitance value from the first capacitance value. The controller receives the output voltage from the pressure sensor in a state where the reference potential layer is floating, and calculates the parasitic capacitance value.
