Abstract: The invention provides a display screen and an electronic device, by disposing a plurality of one or more fingerprint recognition blocks (5) in the active area (AA), with pixel electrode layer (11) corresponding to each sub-pixel unit (SP) comprising a sub-pixel electrode (111) and a fingerprint recognition electrode (112) spaced from the sub-pixel electrode (111), the corresponding BM layer (21) comprising a black frame (211) covering the sub-pixel electrode(111) peripheral and a black block (212) covering the fingerprint recognition electrode (112); and disposing the fingerprint recognition signal lines (13) contacting the fingerprint recognition electrode (112) to electrically connect the fingerprint recognition electrode (112) to an integrated chip (9) of display and fingerprinting recognition. The invention is capable of integrating a fingerprint recognition function in a display area having a low resolution and without a touch function, enabling full-screen multi-block fingerprint recognition without time-division scanning.

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.

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.
