Problems solved by technology

The light emitted by the light-emitting layer passes through the anode / cathode, organic / inorganic film and then emerges from the light-emitting surface. Due to the difference in refractive index between the air, most of the light output in the vertical downward direction or in the vertical downward direction can be effectively output, and part of the light output in the horizontal direction or in the horizontal direction will be eliminated. Blocked in the film layer, resulting in the loss of light that cannot be output, which seriously affects the light extraction efficiency of the display product

Abstract

The invention relates to a display panel and a preparation method thereof. The display panel comprises an array substrate, a pixel limiting layer located on the array substrate and a light-emitting functional layer located on the side, away from the array substrate, of the pixel limiting layer, the pixel limiting layer comprises a plurality of pixel openings arranged in an array mode, and the light-emitting functional layer comprises a plurality of light-emitting elements. The light-emitting element comprises a first electrode, a light-emitting structure located on the first electrode and a second electrode located on the light-emitting structure, the second electrode is located on the side, away from the array substrate, of the first electrode, the first electrode is exposed out of the pixel openings, the pixel limiting layer further comprises a step-shaped groove located between every two adjacent pixel openings, and the step-shaped groove is located between every two adjacent pixel openings. The step-shaped groove is arranged in a gradually-shrinking mode in the direction towards the array substrate. According to the display panel, the light emitting efficiency is improved, and the display effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Organic electroluminescence (OLED, Organic Light Emitting Diode) is a phenomenon in which organic materials are excited by electrical energy to emit light. The light emitted by the light-emitting layer passes through the anode / cathode, organic / inorganic film and then emerges from the light-emitting surface. Due to the difference in refractive index between the air, most of the light output in the vertical downward direction or in the vertical downward direction can be effectively output, and part of the light output in the horizontal direction or in the horizontal direction will be eliminated. Blocked in the film layer, resulting in the loss of light that cannot be output, which seriously affects the light extraction efficiency of the display product. Contents of the invention [0003...
