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 type distinguishing method may be provided for a touch input device including a touch screen. The method may determine a touch on the touch screen. For example, a touch on the touch screen may be determined as an authentication touch when a condition that the time period for which the input touch maintains is equal to or greater than the predetermined reference time period is satisfied prior to the long touch determination criterion time point. The touch on the touch screen may be determined as a long touch when the condition is not satisfied.
