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: A touch input device includes an organic light emitting display module; a pressure sensor including a pressure electrode outputting a first sensing signal for detecting a touch pressure and which is attached under the organic light emitting display module; a touch sensor including drive electrodes to which a driving signal is applied and receiving electrodes outputting a second sensing signal for detecting a touch position; and a substrate located under the organic light emitting display module. The substrate is spaced apart from the organic light emitting display module and includes a reference potential layer. A controller detects a magnitude of the touch pressure based on the first sensing signal. The organic light emitting display module is bent by the touch pressure. A distance between the pressure electrode and the reference potential layer is changed according to a bending of the organic light emitting display module.
