Abstract

An embodiment of the invention provides a display panel and a display device. The absorption and scattering functions of an organic film layer in the light ray propagation process are reduced throughthinning treatment of a partial area of the thicker organic film layer of the display panel, the effective transmission rate on the display panel is increased, and loss and crosstalk of light ray signals after light rays pass by an organic film in the fingerprint recognition process are reduced, so that the sensitivity and the recognition accuracy of light-sensing fingerprint recognition are 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...
