AI Technical Summary

Technical Problem

Existing OLED display panels suffer from inconsistent light extraction rates and color shift at viewing angles, which affect display performance.

Method used

The design employs a lens layer, comprising a first light-adjusting layer and a second light-adjusting layer. The two layers have different refractive indices and their sidewalls form different angles with the substrate plane, thereby adjusting the convergence degree of light of different emitting colors to be consistent.

Benefits of technology

It improves the consistency of light extraction rate for different emitting colors, reduces color distortion at viewing angles, and enhances the display effect and performance of the display panel.

Abstract

The application discloses a display panel, a mask and a display device. The display panel comprises a substrate, light-emitting elements of at least two light-emitting colors and a lens layer. The light-emitting elements are located on one side of the substrate. The lens layer is located on the side of the light-emitting elements away from the substrate. The lens layer comprises a first light adjusting layer and a second light adjusting layer. The first light adjusting layer is arranged at least partially around the light-emitting elements. The refractive index of the first light adjusting layer is different from that of the second light adjusting layer. The light-emitting elements of at least two light-emitting colors comprise first light-emitting elements and second light-emitting elements. The first light adjusting layer comprises a first side wall around the first light-emitting elements and a second side wall around the second light-emitting elements. The angle between the first side wall and the plane where the substrate is located is a first angle. The angle between the second side wall and the plane where the substrate is located is a second angle. The first angle is different from the second angle. The technical scheme of the application improves the use performance of the display panel.
