A display panel, its manufacturing method and display device

Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device, comprising: a plurality of light-emitting units, a packaging component located on the light-emitting side of the light-emitting unit, and a plurality of closely arranged protrusions located on the surface of the packaging component away from the light unit. raised structure, and a protective cover located on the side of the raised structure away from the packaging component; an air atmosphere is formed between the protective cover and the raised structure; wherein, the cross-sectional area of ​​the raised structure parallel to the plane where the light-emitting unit is located varies with the light-emitting unit decrease as the distance between them increases. After the large-angle light emitted by the light-emitting unit enters the raised structure on the light-emitting side, since the slope of the raised structure can reduce the incident angle of the light incident on the interface between the raised structure and the air medium, it can make the original occurrence Totally reflected light can be emitted, thereby increasing the emission of light and improving the brightness of the display.

Description

Technical field [0001] The present invention relates to display technology, and particularly relates to a display panel, a display device and a manufacturing method thereof. Background technique [0002] Miniature silicon organic light emitting diode display device (Micro Organic Light Emitting Diode, referred to as Micro-OLED) technology is based on the OLED display device is an active single-crystal silicon produced by driving the backplane; compared to conventional glass as an OLED backplane a display device, Micro-OLED in addition to a self-emitting, thin, light weight, large viewing angle, a short response time, higher external efficiency of light emission characteristics, the PPI is easier to achieve high, small size, easy to carry, is excellent in low power consumption characteristics, thus It is especially suitable for head mounted display, a goggle type display, AR / VR display devices. [0003] But at this stage of the Micro-OLED display ubiquitous low brightness, dim d...

AI Technical Summary

Problems solved by technology

[0003] However, the current Micro-OLED generally has the problem of low display brightness and dark display, which limits the promotion of its application.
