MOBILE PHONE WITH TOUCH INPUT DISPLAY

摘要

A smartphone includes: a cover layer; an LCD panel which is located under the cover layer and comprises a liquid crystal layer, and a first glass layer and a second glass layer between which the liquid crystal layer is placed, wherein 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; a backlight unit which is located under the LCD panel;
a pressure electrode which is located under the backlight unit; and a shielding member which is located under the pressure electrode. The touch sensor comprises a plurality of drive electrodes and a plurality of receiving electrodes. A drive signal is applied to the touch sensor and 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.
