1. A smartphone comprising:
a first cover layer; an LCD panel located under the first cover layer and comprising a liquid crystal layer, a first glass layer, and a second glass layer, the liquid crystal layer located between the first glass layer and the second glass layer; a backlight unit located under the LCD panel and comprising an optical film, a light source, a reflective sheet, and a second cover layer; and a touch sensor which senses touch in a capacitive manner; wherein the backlight unit further comprises a pressure sensor and a spacer layer, the pressure sensor comprising a plurality of electrodes formed in a single layer attached on the second cover layer and spaced apart from the reflective sheet, the pressure sensor located between the reflective sheet and the second cover layer; wherein a driving signal is applied to the touch sensor and 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 output from the pressure sensor and 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 change amount of the capacitance output from the pressure sensor changes as the LCD panel bends. |
