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 control method for a touch sensor panel is disclosed. The method includes obtaining touch information on the touch sensor panel from which an electrical signal outputted is changed according to a touch; detecting at least one valid touch from the touch information; determining that a valid touch of the at least one valid touch is included in a palm touch group by (a) detecting a palm touch (e.g., which meets a palm touch condition) among the at least one valid touch, and (b) determining valid touches (e.g., all valid touches) from a detection time of the palm touch to a predetermined backward tracking time; and non-displaying, on a display unit, the valid touch included in the palm touch group.
