Problems solved by technology

However, after the small holes are opened in the light-shielding layer, when the display panel displays images, the amount of light exiting the panel at a large angle will increase, which will cause viewing angle deviation and adversely affect the display.

Abstract

The embodiment of the invention provides a display panel and a display device, relates to the technical field of display, and aims to improve the visual angle color cast phenomenon. The display panel includes a light emitting element; a light blocking layer which comprises a light transmitting hole; and a light shielding layer having an opening; wherein the projection of the light-transmitting hole on the substrate is a first orthographic projection and has a first central point, the projection of the opening on the substrate is a second orthographic projection, and the edge of the second orthographic projection is provided with a first point; the minimum distance between the first central point and the first point is a first distance, and the maximum distance between the first central point and the first point is a second distance; the distance d1 between the first center point of the first light hole and the first center point of the adjacent second light hole is the distance between the light shielding layer and the light emitting surface, d2 is the distance between the light shielding layer and the light shielding layer, L1 is the first distance between the first orthographic projection of the first light hole and the adjacent second orthographic projection, and L2 is a second distance between the first orthographic projection of the first light hole and the adjacent second orthographic projection.

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 a display panel with a fingerprint identification function, the display light of the panel is usually used as the detection light for fingerprint identification. When a finger touches the panel, the light emitted by the light-emitting element is transmitted to the finger and reflected by the finger, and the reflected light enters the fingerprint recognition module, which collects the light reflected from different positions to generate fingerprint images of different positions , and then get a complete fingerprint image through synthetic analysis. [0003] In the prior art, in order to reduce the reflection of the metal layer in the panel to the external ambient light, it is necessary to install a light-shielding layer on one side of the light-emitting surface of the display panel. In order to a...
