A display panel and display device

By creating a third opening in the light-shielding layer of the display panel that does not block light, the light-transmitting area is increased, solving the problems of low screen-to-body ratio and black holes in the display area, thus achieving a full-screen display with high screen-to-body ratio and good display effect.

AI Technical Summary

Technical Problem

Existing display panels suffer from low screen-to-body ratio and black holes in the display area, which affect the display effect.

Method used

A third opening that does not block light is made in the light-shielding layer of the display panel to form a light-transmitting area, increasing the transmittance of the display area. At the same time, a third opening is made in the light-shielding layer to increase the area of ​​the light-transmitting area, ensuring that the increase in visible light reflectance is small and avoiding dark visual effects.

Benefits of technology

The screen-to-body ratio and transmittance of the display panel have been improved, achieving a full-screen display effect while ensuring good display quality.

Abstract

The application discloses a display panel and a display device, and relates to the technical field of display panels, and specifically discloses a display panel and a display device, wherein the display panel comprises a display area and a first area in the display area; the display area comprises a substrate, a pixel definition layer, a plurality of light emitting elements and a light shielding layer arranged in sequence, the pixel definition layer has a plurality of first openings, the light shielding layer has a plurality of second openings, and the light emitting elements are located in the first openings; the light shielding layer in the first area further has at least one third opening; along a first direction, the second openings overlap the first openings, and the third openings do not overlap the first openings, and the first direction is parallel to the film layer stacking direction in the display area. In the application, the display area comprises the first area, the light shielding layer in the first area has at least one third opening; along the first direction, the third openings do not overlap the first openings, the third openings are structures that do not block light, the transmittance of the first area can be increased, the visible light reflectance of the first area has a small increase, the third openings will not cause the first area to have a serious dark state visual effect, and a full-screen display is realized.
