Abstract

The invention discloses a display panel and a display device; the display panel comprises the following units: an array substrate; a plurality of luminescence units arranged on the array substrate, wherein each luminescence unit comprises a plurality of sub-luminescence units; a plurality of fingerprint identification units used for identifying the fingerprint lights reflected on the fingerprint identification unit by a touch main body, wherein each fingerprint identification unit is matched with at least one sub-luminescence unit; the vertical projections of the fingerprint identification unit and the matching sub-luminescence unit overlap on the array substrate. The display panel can effectively prevent the moire phenomenon caused by inaccurate contraposition between the fingerprint identification unit and the sub-luminescence unit, thus improving the display effect of the display panel.

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] Existing display panels with fingerprint recognition function all include a plurality of light emitting units and a plurality of fingerprint recognition units. The fingerprint recognition unit can perform fingerprint recognition according to the reflected light formed by the light emitted by the light source afte...
