Abstract:
The present invention provides a force touch display device, including a liquid crystal display (11), a backlight module (12), a backlight module bottom frame (121), a shield layer (2), a pressure sensor (13) and a middle frame (14). With the shield layer (2) providing a function of shielding an electromagnetic noise signal being used inside the display device, the interference applied on the pressure sense result of the pressure sensor by the electromagnetic noise signal inside the force touch display device is effectively reduced, and thus the force touch sensitivity of the force touch display device is improved.
