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.

Abstract: An exemplary embodiment of the present invention provides a stylus pen including: a body; a conductive tip configured to be exposed from an inside of the body to an outside thereof; and a resonance circuit connected to the conductive tip to resonate an electrical signal transferred from the conductive tip. An inductor unit of the resonance circuit includes a ferrite core and a coil wound in multiple layers over at least a portion of the ferrite core. The ferrite core includes nickel, and the coil can be formed by a litz wire with adjacent winding layers that are wound to be inclined in a zigzag form.

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 smartphone may include a first cover layer and an LCD panel. A backlight unit may be located under the LCD panel. A touch sensor may sense touch in a capacitive manner. The backlight unit may include a pressure sensor and a spacer layer. The pressure sensor includes a plurality of electrodes formed in a single layer attached on the second cover layer and spaced apart from the reflective sheet. A driving signal is applied to the touch sensor and a touch position is detected by a sensing signal. A magnitude of a touch pressure is detected based on a change amount of capacitance which is output from the pressure sensor and which is changed according to a distance between the pressure sensor and an electrode located within the LCD panel. The pressure sensor is attached on the second cover layer as an integral sheet including insulation layers.

Abstract: In one embodiment, a touch input device capable of detecting a pressure of a touch on a touch surface is disclosed. The touch input device includes a substrate and a display module. A common voltage electrode is disposed within the display module. The touch input device further comprises an electrode which is disposed at a position where a distance between the electrode and the common voltage electrode changes according to the touch on the touch surface. The distance changes according to a magnitude of the pressure of the touch. Further, an electric signal depending on the distance is outputted from the electrode.
