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

Embodiments of the present invention provide a display panel and a display device. By thinning the organic film layer with a relatively large thickness of the display panel in some areas, the absorption of light by the organic film layer during the light propagation process is reduced. The scattering effect improves the effective light transmittance on the display panel, reduces the loss and crosstalk of light signals after the light passes through the organic film in the process of fingerprint recognition, thereby improving the sensitivity and recognition accuracy of light-sensitive fingerprint recognition.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, and 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, at present, the display area can be reused as the fingerprint recognition area by using the fingerprint recognition technology under the screen. When the display area is multiplexed into a fingerprint identification area, a plurality of fingerprint identification units are also arranged at the positions corresponding to the fingerprint identification area in the display panel. During fingerprint identification, 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 identifi...
