Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate, a plurality of organic light-emitting structures and a plurality of fingerprint identification modules, wherein the plurality of organic light-emitting structures and the plurality of fingerprint identification modules are arranged on a display region of the array substrate, and each fingerprint identification module is arranged between two adjacent organic light-emitting structures and comprises a photoelectric diode and a storage capacitor; in a direction far away from the array substrate, each fingerprint identification module comprises a first electrode, a second electrode and a third electrode, the storage capacitor comprise the first electrode and the second electrode, the photoelectric diode comprises the second electrode, the third electrode and a PN junction, and the PN junction is arranged between the second electrode and the third electrode; and in the direction far away from the array substrate, each organic light-emitting structure comprises a positive electrode, a negative electrode and a light-emitting functional layer, the light-emitting functional layer is arranged between the positive electrode and the negative electrode, and the negative electrode is electrically connected with the first electrode and the third electrode. By the technical scheme, the process of the display panel is reduced, and the fabrication cost of the display panel is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Fingerprints are inherent to everyone. With the development of technology, a variety of display devices with fingerprint recognition functions have appeared on the market, such as mobile phones, tablet computers, and smart wearable devices. Before operating the display device with the fingerprint identification function, the user only needs to touch the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display devices with fingerprint identification function, fingerprint identification can be performed by using an external fingerprint identification module, that is, the fingerprint identification module is arranged on the side of the array substrate away from the display unit, but this external ...
