More Information
Summary:A smartphone includes: a cover layer; a display module which is located under the cover layer and comprises an LCD panel comprising a liquid crystal layer, and a first glass layer and a second glass layer between which the liquid crystal layer is placed, and comprises a component configured to cause the LCD panel to perform a display function; a pressure electrode which is located under the display module; and a shielding member which is located under the pressure electrode. At least a portion of a touch sensor which senses touch in a capacitive manner is located between the first glass layer and the second glass layer. The touch sensor comprises a plurality of drive electrodes and a plurality of receiving electrodes. A touch position is detected by a sensing signal which is outputted from the touch sensor. A magnitude of a touch pressure is detected based on a change amount of capacitance outputted from the pressure electrode.
