Problems solved by technology

[0003] However, in the prior art, due to the relatively compact arrangement of various film layers and other components in the drive unit of the display panel, the proportion of the light-transmitting area on the display panel is not high, which affects the exit and entry of light and thus affects Light-sensitive fingerprint recognition sensitivity

Abstract

The embodiment of the invention provides a display panel and a display device. The pixel distribution density of a fingerprint identification area of the display panel is reduced. The specific approach is that the number of light emitting units and the number of driving circuits on a corresponding driving array substrate are reduced, and the requirement of visual resolution is met by adopting a mode of pixel rendering at the same time. Through reducing the driving circuits on the driving array substrate, the light transmission area is increased, and the effective light transmission area on thedisplay panel is improved, so that the overall light transmittance is greatly improved, and the sensitivity of photosensitive fingerprint identification is improved.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] For the display panel with fingerprint recognition function, in order to better realize the full-screen design and avoid the fingerprint recognition area occupying the space of the non-display area, the display area can be reused as the fingerprint recognition area by using the under-screen fingerprint technology. When the display area is multiplexed as a fingerprint identification area, multiple fingerprint identification units are also arranged in the position corresponding to the fingerprint identification area in the display panel. When fingerprint identification is performed, the light emitted by the light source is reflected by the finger and enters the fingerprint in a specific area. In the identification unit, the fingerprint identification unit further identifies valleys and ridges of the fi...
