Abstract

The invention discloses a display device which comprises a miniature light-emitting diode lamp panel. The miniature light-emitting diode lamp panel comprises a light reflecting layer, wherein the thickness of the area, close to an opening, of the light reflecting layer is smaller than that of the area, away from the opening, of the light reflecting layer. Therefore, the light reflecting layer close to a miniature light-emitting diode can be thinned, the problem that the miniature light-emitting diode is overlapped on the reflective layer in the welding process and cannot be straightened is solved, and the welding yield of the miniature light-emitting diode is improved; meanwhile, the area, except the area close to the opening, of the light reflecting layer is large in thickness, so that most of the area of the light reflecting layer has is guaranteed to have high reflectivity, most of light can beguaranteed to be effectively reflected, and the light emitting efficiency of the miniature light emitting diode lamp panel is not affected.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] As the current mainstream display screen, liquid crystal display has the advantages of low power consumption, small size, and low radiation. The liquid crystal display panel is a non-self-illuminating panel and needs to be used in conjunction with a backlight module. [0003] Mini Light Emitting Diode (Mini LED for short) as backlight has become a current hotspot in liquid crystal display technology. Unlike traditional liquid crystal display, which uses a light guide plate side-entry backlight solution, it uses a huge number of Mini LEDs as backlight. source, not only can realize the thinning of the backlight, but also can achieve more refined dynamic control and improve the dynamic contrast of the liquid crystal display. [0004] At present, the surface of the Mini LED light board has a layer of reflective material, and ...
