Abstract
The invention discloses a display panel and a display device. The display panel comprises: an array substrate, a luminescent functional layer and a pixel definition layer, the array substrate comprises a base substrate and a thin film transistor array, and the luminescent functional layer comprises a first electrode, a luminescent material layer and the second electrode, the first electrode is located on the first electrode layer; the thin film transistor array is arranged on one side of the base substrate, and the first electrode layer is arranged on the side of the thin film transistor array away from the base substrate, including a plurality of first electrodes, The pixel definition layer is disposed on the side of the first electrode layer away from the base substrate, and includes a plurality of opening areas and a plurality of non-opening areas surrounding the opening areas, the first electrode is at least located in the opening area, and at least part of the first electrodes have a first area and the second area, the light transmittance of the second area is greater than the light transmittance of the first area; the fingerprint identification array includes several fingerprint identification sensors, which are arranged on the side of the first electrode layer away from the pixel definition layer. Through the present invention, the accuracy of fingerprint recognition can be improved.
Description
technical field [0001] The present invention relates to the field of display technology, and more particularly, 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 a display device with a fingerprint recognition function, the user only needs to touch the display device with a finger to perform authorization verification, which simplifies the authorization verification process. Moreover, with the gradual increase in the application scenarios of the fingerprint recognition function, the fingerprint recognition area is gradually changed from Some areas have evolved into full-screen recognition. [0003] In the existing display devices based on optical fingerprint recognition technology, the fingerprint re...
