Abstract

The invention discloses a display panel and a display device. The display panel comprises a light-emitting layer, wherein opposite light-out directions are formed at two sides of the light-emitting layer, and a light-guiding layer and a sensing layer are sequentially arranged in a stacked mode in one light-out direction; the light-guiding layer is used for emitting light, which is emitted by the light-emitting layer to the light-guiding layer, to the sensing layer at a predetermined angle; and the sensing layer comprises multiple first light-transmitting regions and first light-shading regionssurrounding the corresponding first light-transmitting regions, and each first light-transmitting region is provided with a photosensitive element. According to the scheme, the light-emitting layer has the two opposite light-out directions, one of the light-out directions serves as a display surface, and the other light-out direction serves as a light source for fingerprint recognition; and during fingerprint recognition, it is needless to perform highlighting display on a local region, thus, aging of a specific region cannot be intensified, and the problem of non-uniform luminance caused bylocal aging does not exist. Besides, fingerprint recognition and picture display are realized at the two sides respectively, and therefore an adverse influence cannot be imposed on display.

Description

technical field [0001] The present invention generally relates to the field of display technology, and in particular to a display panel and a display device. Background technique [0002] Under-screen fingerprint recognition is an emerging fingerprint recognition technology, which is to set the fingerprint recognition area in the predetermined display area of ​​the display screen, set the photosensitive element in the fingerprint recognition area, and set the display area of ​​the photosensitive element on the display screen when performing fingerprint recognition. The brightness is increased to provide enough light to irradiate the user's finger, so that the photosensitive element receives enough light reflected by the finger for fingerprint recognition. When fingerprint recognition is required, the brightness of the area where the photosensitive element is set needs to be increased, which affects the display effect. In addition, because the area of ​​the photosensitive ele...
