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.

Abstract: A touch display panel and a touch display device are provided, which include a display substrate and a touch panel. The touch panel includes a first touch zone corresponding to a regular display area of the display substrate and a second touch zone corresponding to an irregular display area of the display substrate. The first touch zone includes at least one first touch electrode, the second touch zone includes at least one second touch electrode, and at least a portion of the second touch electrode extends into the first touch zone. Thus, areas of the second touch electrode and the first touch electrode are equal or as similar as possible, thereby improving a touch sensitivity and accuracy and a uniformity of display of the touch display panel and the touch display device.

Abstract: The present disclosure relates to an in-cell touch display panel and an electronic device. The in-cell touch display panel includes a plurality of photo spacers (PSs) being configured to stand on the protection layer along an extending direction of the virtual lines, and the virtual lines are disconnected in standing locations of the PSs. The PSs avoid the metallic wiring layer, and the standing locations of PSs are more flat. As such, the supporting height of the PSs are the same, and the cell thickness is uniform. The dark stripe issue caused by the configuration of the PSs may be avoided, and so does the un-recoverable Push Mura, water ripple, and bright and dark spots. At the same time, the surface pressure and the display performance of the in-cell touch display panel may be enhanced.
