Abstract: A smartphone may include a first cover layer and an LCD panel. A backlight unit may be located under the LCD panel. A touch sensor may sense touch in a capacitive manner. The backlight unit may include a pressure sensor and a spacer layer. The pressure sensor includes a plurality of electrodes formed in a single layer attached on the second cover layer and spaced apart from the reflective sheet. A driving signal is applied to the touch sensor and a touch position is detected by a sensing signal. A magnitude of a touch pressure is detected based on a change amount of capacitance which is output from the pressure sensor and which is changed according to a distance between the pressure sensor and an electrode located within the LCD panel. The pressure sensor is attached on the second cover layer as an integral sheet including insulation layers.

Abstract: In one embodiment, a method for operating a camera included in a touch input device including a touch screen is disclosed. A processor determines a capacitance pattern for a varying capacitance throughout the touch screen when the touch screen is underwater and no touch input occurs. The processor resets a varying reference capacitance for determining whether a touch input by an object occurs or not, the varying reference capacitance being reset based on the determined capacitance pattern when the touch screen is underwater and no touch input occurs. The touch screen receives a touch pressure by the object underwater. Operation of the camera is controlled according to the touch pressure to the touch screen.

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.
