In one embodiment, a touch input device includes a touch screen and is configured to perform mutually different operations with respect to a first touch and a second touch on the touch screen. The first touch is maintained during a time period equal to or greater than a first time period, wherein the first touch is maintained at a pressure less than a first pressure within the first time period. The second touch has a time interval having a pressure greater than the first pressure within the first time period. The first pressure is controlled and set by an input to the touch screen.

In one embodiment, a touch input device capable of detecting a pressure of a touch on a touch surface includes a display panel and an electrode disposed under the display panel. An electrical characteristic detected at the electrode is changed by the bending of the display panel. A magnitude of the pressure applied to the touch surface is detected according to the change amount of the electrical characteristic. The display panel includes a first area and a second area. A pressure detection sensitivity of the first area is higher than a pressure detection sensitivity of the second area. When the first area and the second are bens to the same degree, a change amount of the electrical characteristic detected when a pressure is applied to the second area is greater than a change amount of the electrical characteristic detected when a pressure is applied to the second area.
Abstract:
In one embodiment, a touch input device includes a first electrode; a second electrode located on one side of the first electrode; a display disposed on one side of the first electrode opposite to the second electrode; and a spacer layer between the first electrode and the second electrode. One of the first electrode and the second electrode is a drive electrode, and the other 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 the display, the first electrode is concavely bent toward the second electrode. The mutual capacitance between the electrodes changes according to a distance between the electrodes. The magnitude of the external pressure according to the change of the capacitance between the electrodes is detected.

The touch input device detects the touch pressure on the basis of a capacitance change amount according to a change of a distance between the pressure electrode and the reference potential layer. As a result of this, the touch input device becomes thinner, has a reduced manufacturing cost thereof, and detects a touch position and touch pressure without deteriorating the visibility and optical transmittance of the display module.

A driving signal is controlled to include a plurality of time intervals in which the driving signal is applied to at least one of at least two driving signal electrodes simultaneously driven, and in which the driving signal is not applied to at least one of at least two driving signal electrodes simultaneously driven.

At least one among the driving signals which are simultaneously applied to the driving signal electrode has a phase difference from the other driving signals.
