    Abstract: A pressure detection module may be provided that includes: a first electrode and a second electrode which are located on an insulation layer; and an elastic foam. The elastic foam is located between the first and the second electrodes and a reference potential layer located apart from the pressure detection module. A capacitance between the first electrode and the second electrode is changed according to a relative distance change between the reference potential layer and the first and the second electrodes through a transformation of the elastic foam. A magnitude of a pressure which causes the elastic foam to be transformed is detected according to the capacitance change.

    Abstract: In one embodiment, a touch input device capable of detecting a pressure of a touch on a touch surface is disclosed. The touch input device includes a substrate and a display module. A common voltage electrode is disposed within the display module. The touch input device further comprises an electrode which is disposed at a position where a distance between the electrode and the common voltage electrode changes according to the touch on the touch surface. The distance changes according to a magnitude of the pressure of the touch. Further, an electric signal depending on the distance is outputted from the electrode.

    Abstract: A virtual touch pad operation method includes: determining whether or not a hovering input or a touch input to a touch screen meets a predetermined condition; entering a virtual touch pad mode when the hovering input or the touch input meets the predetermined condition; and operating a virtual touch pad. A terminal includes: a touch screen; and a controller which controls a hovering input or a touch input to the touch screen and displays a virtual touch pad on a portion of the touch screen by the hovering input, or the terminal includes: a touch screen, and a controller which distinguishes a touch input to a virtual touch pad in accordance with a pressure magnitude or area of the touch and controls the operation of the virtual touch pad. The virtual touch pad is formed on a portion of the touch screen by the touch input satisfying a predetermined condition.

    Abstract: 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 bent 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 first area.
