Abstract: A pressure detection module may be provided that includes: a first electrode and a second electrode which are located on an insulation layer; and an elastic foam. The elastic foam is located between the first and the second electrodes and a reference potential layer located apart from the pressure detection module. A capacitance between the first electrode and the second electrode is changed according to a relative distance change between the reference potential layer and the first and the second electrodes through a transformation of the elastic foam. A magnitude of a pressure which causes the elastic foam to be transformed is detected according to the capacitance change.

Abstract: A touch input device is disclosed that may comprise a display panel and/or a touch sensor. The touch sensor may include a driving electrode and/or a receiving electrode that may be disposed on the display panel and/or inside the display panel. The touch input device may comprise an electrode pattern that may be disposed on a bottom surface of the display panel. The touch input device may comprise a controller that may be configured to provide a first driving signal to the driving electrode of the touch sensor. The controller may be configured to receive a touch detection signal from the receiving electrode of the touch sensor. The controller may be configured to detect a touch position, perhaps for example based on the touch detection signal. The controller may be configured to provide a second driving signal different from the first driving signal to the electrode pattern.
