AI Technical Summary

Technical Problem

Existing OLED display panels suffer from inconsistent brightness decay rates due to inconsistent aperture lengths of subpixels in the same direction, leading to color shift issues and poor display performance.

Method used

An insulating pad structure is provided in the first pixel opening area of the pixel limiting layer so that it contacts the first anode, and a light-shielding structure is provided on the side of the light-emitting functional layer away from the substrate so that it overlaps with the insulating pad structure in a direction perpendicular to the substrate, thereby narrowing the effective light-emitting opening length of the first sub-pixel in the first direction.

Benefits of technology

The color shift problem has been improved, making the brightness decay rate of different sub-pixels more consistent under different viewing angles, thus improving the display effect.

Abstract

This utility model discloses a display panel and a display device. The display panel includes a substrate, an anode layer, a pixel defining layer, an insulating pad structure, a light-emitting functional layer, and a first light-shielding structure. The anode layer includes a first anode, a second anode, and a third anode, the lengths of the second and third anodes in a first direction being less than the length of the first anode in the first direction. The pixel defining layer includes a first pixel opening that exposes a portion of the first anode. The orthographic projection of the insulating pad structure onto the substrate is located within the orthographic projection range of the area where the first pixel opening is located on the substrate and is in contact with the first anode. The light-emitting functional layer includes a first light-emitting unit located within the first pixel opening and in contact with both the insulating pad structure and the first anode. The first light-shielding structure is located on the side of the light-emitting functional layer away from the substrate. Along a direction perpendicular to the plane of the substrate, the projections of the first light-shielding structure and the insulating pad structure overlap. The technical solution of this utility model can improve color shift.
