Problems solved by technology

However, part of the light transmitted from the color-resist layer will be blocked by the light-shielding layer and cannot be emitted from the light-emitting side of the display panel, resulting in a relatively low luminance of the display panel.

Abstract

The embodiment of the invention discloses a display panel and a display device. It includes a color filter substrate and an array substrate, the array substrate includes a plurality of photosensitive units; the color filter substrate includes a first base substrate, a first light-shielding layer and at least one second light-shielding layer sequentially arranged toward the side of the array substrate; the first light-shielding layer The layer includes at least two sub-light-shielding layers, each sub-light-shielding layer is provided with a first opening; each second light-shielding layer is provided with a second opening; the first opening, the second opening and the photosensitive unit are on the first base substrate The vertical projections of are at least partially coincident; the maximum distance between the edge of the first shading layer and the edge of the first opening is L 1 ; The maximum distance between the edge of the second light-shielding layer and the edge of the second opening of the second light-shielding layer is L 2 ; L 1 <l2. The thickness of the first light-shielding layer is greater than the thickness of any second light-shielding layer. The technical solutions provided by the embodiments of the present invention can reduce the shielding degree of the outgoing light by the first light-shielding layer, and improve the luminance of the display panel.< / l

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] At present, in-screen fingerprint recognition, that is, embedding the fingerprint recognition unit in the display area, is a hotspot in the current display field research, which is conducive to improving the screen-to-body ratio of the display. [0003] Existing fingerprint identification technologies include optical fingerprint identification technology, semiconductor silicon fingerprint identification technology and ultrasonic fingerprint identification technology. Among them, the optical fingerprint recognition technology generally uses a photodiode as the light-sensing unit. Its working principle is: the reflected light formed after the light is reflected by the touch body is irradiated on the photodiode, so that the photodiode generates a photocurrent. There is a difference in th...
