AI Technical Summary

Technical Problem

The reflected light inside the display reduces the contrast of the picture and affects the display effect.

Method used

A display panel is designed, including a substrate substrate, a first reflective layer, a driving circuit layer, and a plurality of light emitting structures. The first reflective layer consists of a layer of reflective material and a plurality of triangular pyramids. The bottom surface of the triangular pyramid is parallel to the substrate substrate, and the side angle is 90°. The reflective material layer covers the triangular pyramids to form an angle reflector to limit and consume reflected light.

Benefits of technology

By limiting the reflection and consumption of reflected light in the pyramid, the reflected light is greatly reduced, the picture contrast is improved, and the display effect is improved.

Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, a first reflecting layer, a driving circuit layer and a plurality of light-emitting structures. The first reflecting layer comprises a reflecting material layer and a plurality of triangular pyramids, wherein the reflecting material layer is located on the first surface of the substrate. The bottom face of the triangular pyramid is parallel to the first surface of the substrate, and the included angle between every two of the three side faces of the triangular pyramid is 90 degrees. The reflecting material layer is located on the sides, away from the substrate, of the triangular pyramids and covers the triangular pyramids. The driving circuit layer is located on the side, away from the substrate, of the first reflecting layer. The multiple light emitting structures are located on the side, away from the substrate, of the driving circuit layer. The driving circuit layer comprises driving circuits of the light-emitting structures, and the driving circuits are connected with the corresponding light-emitting structures.
