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.

Abstract: In one embodiment, a touch sensor includes a first electrode, a second electrode, and a spacer layer located between the first electrode and the second electrode. One of the first electrode and the second electrode is a drive electrode to which a drive signal is applied. The other one of the first electrode and the second electrode is a receiving electrode that receives the drive signal by a mutual capacitance between the first electrode and the second electrode. When an external pressure is applied to the first electrode through a display, the first electrode is concavely bent toward the second electrode. The mutual capacitance between the first electrode and the second electrode changes according to a distance between the first electrode and the second electrode. The magnitude of the external pressure according to the change of the capacitance between the first electrode and the second electrode is detected.

Abstract: A touch input device which includes a display module and is capable of detecting a pressure may be provided. The touch input device includes: a display module including a flat portion and at least one curved portion which extends from the flat portion and is curved with a predetermined curvature; and a pressure detection module which is formed under the display module and detects a touch pressure applied to a surface of the display module. The pressure detection module detects the touch pressure on the basis of a capacitance change amount according to a distance change between a reference potential layer and the pressure detection module. As a result, the touch input device including various types and forms of the display modules is capable of efficiently detecting the touch position and touch pressure.
