    Abstract: A display panel includes a sub-pixel array and a plurality of photosensitive units. The sub-pixel array includes as first sub-pixel, a second sub-pixel and a third sub-pixel that are capable of emitting light of different colors. The plurality of photosensitive units are disposed under a light-emitting surface of the sub-pixel array. Each of the plurality of photosensitive units includes a photosensitive device, and the photosensitive device includes a photosensitive layer; and an orthographic projection of the photosensitive layer in the photosensitive device on a panel surface of the display panel has overlapping regions with orthographic projections of the first sub-pixel, the second sub-pixel and the third sub-pixel on the panel surface of the display panel.

    Abstract: 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.

    Abstract: At least one embodiment of this disclosure provides a display apparatus for solving the problem of a low identification precision due to a relatively large distance between the finger and the fingerprint identification device. The display apparatus comprises a display panel and at least one fingerprint identification device. Each fingerprint identification device comprises a plurality of identification units arranged in an array, each identification unit being provided with a photosensitive element. The photosensitive element is used for performing photoelectric conversion of incident light. The fingerprint identification device further comprises a collimating filter layer arranged on a light entrance surface of the photosensitive element. The collimating filter layer comprises a plurality of strip-shaped light guide portions arranged to be spaced and parallel, a longitudinal direction of the plurality of strip-shaped light guide portions being substantially perpendicular to the light entrance surface of the photosensitive element.
