Abstract
In one embodiment, a smartphone includes a first cover layer; an LCD panel located under the first cover layer; a backlight unit located under the LCD panel and comprising a reflective sheet and a second cover layer; and a capacitive touch sensor; wherein the backlight unit further comprises a pressure sensor and a spacer layer, the pressure sensor comprising electrodes attached on the second cover layer and spaced apart from the reflective sheet; wherein a touch position is detected by a sensing signal output from the touch sensor; wherein a magnitude of a touch pressure is detected based on a change amount of capacitance that is changed according to a distance between the pressure sensor and an electrode located within the LCD panel; wherein the LCD panel is bent according to the touch; and wherein the capacitance change amount changes as the LCD panel bends.
