Abstract: An array substrate comprises a common electrode, an insulation layer, and a sensing layer, the common electrode comprises the touch electrodes, they are in spaced arrangement, the sensing layer comprises the touch traces and the suspending traces, the touch trace is disposed above the touch electrode and electrically connects to the touch electrode by the through hole, the suspending trace is disposed above the interval between two of the touch electrodes and electrically connects to the touch trace by the first trace. Using the electrical connection between the suspending trace and the touch trace, the electrical potentials of the suspending trace and the touch electrode are the same, the difference of the electric field between the interval area of the adjacent touch electrodes and the touch electrode decreases for avoiding the electric field formed in the data line under the touch electrode ingresses into the liquid crystal layer.

Abstract: The present application provides a display panel and a display module with variable sub-pixel opening area. The display panel includes a display area, a non-display area, and a transition area disposed between the display area and the non-display area. The transition area comprises a first sub-pixel area and a second sub-pixel area, and the first sub-pixel area comprises a first opening and the second sub-pixel area comprises a second opening. The first opening is disposed closer to the display area than the second opening, and the first opening has an area greater than the area of the second opening.

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: The invention provides a touch display panel and an electronic device, with the positions of pixel electrode layer and common electrode layer at the side of array substrate in conventional touch display panel changed; wherein common electrode layer (21) as touch sensor is changed to the top, and pixel electrode layer (16) is changed to below common electrode layer (21). Pixel electrode (16) is connected to source/drain (145) of TFT (14) via first through hole (V1) penetrating planarization layer (15), which requiring only to drill planarization layer without the need to drill both the protective layer and planarization layer as in prior art to achieve connecting pixel electrode to TFT. The invention saves a mask, a drilling process and production cost and improves production efficiency. Moreover, placing common electrode (21) as touch sensor at the top facilitates optimizing sensitivity and SNR, thereby improves touch performance and product quality.
