摘要： A display array substrate, a manufacturing method and a display are disclosed herein. The display array substrate includes an array substrate base, an electroluminescent diode array substrate arranged above the array substrate base, including an anode layer, a cathode layer, an electroluminescent EL layer between the anode layer and the cathode layer, and a pixel compensation circuit layer on a side close to the array substrate base. The cathode layer is on a side away from the array substrate base. A photosensitive signal collector may be configured to receive an optical signal reflected by valleys and ridges of a finger and emitted by the electroluminescent EL layer, and convert the collected optical signal into an electrical signal to be output. The photosensitive signal collector may be arranged between the pixel compensation circuit layer and the anode layer of the electroluminescent diode array substrate.

摘要： A fingerprint recognition device, a method for fabricating the same, and a display device are disclosed. The first electrically conductive connection member is arranged between the drain of the TFT and photosensitive members, and the photosensitive members are connected with the drain of the TFT through the first electrically conductive connection member. Even when the surface of the drain becomes rough after first vias are formed in the insulating layer, it is the first electrically conductive connection member that is electrically connected with the photosensitive members. The first electrically conductive connection member has a smooth surface. This prevents the effect of formation of first vias in the insulating layer on the optical property of photosensitive members, thus improving performance of the fingerprint recognition device.
