Abstract

The invention discloses a light-emitting assembly, a backlight module and a display device.The light-emitting assembly comprises a lamp bead and a reflector plate, the reflector plate comprises a plurality of reflecting walls, the reflecting walls are sequentially connected end to end and define a reflecting cavity, the two ends of the reflecting cavity are provided with a mounting hole and a light outlet respectively, the lamp bead is mounted in the mounting hole, and the light outlet is arranged in the mounting hole. The light emitting side of the lamp bead faces the light outlet, and the volume of the reflection cavity is gradually increased in the direction from the mounting hole to the light outlet. According to the light-emitting assembly, the lamp beads are installed in the installation holes, so that light rays emitted by the lamp beads are limited in the reflection cavity all the time, the light rays cannot spread outwards, and the halo phenomenon is effectively avoided; and moreover, the reflecting wall is used for reflecting the light rays to the light outlet, so that the light outlet brightness at the light outlet is improved, and the light utilization rate is also improved.

Description

technical field [0001] The present invention relates to the technical field of display devices, and in particular, to a light-emitting assembly, a backlight module and a display device. Background technique [0002] With the development of backlight technology, consumers have higher and higher requirements for TV viewing experience, and TV sets also pay more attention to improving the brightness, contrast and color gamut of TV backlights during production. At present, in order to obtain a higher contrast ratio of TV sets, it is usually achieved by means of local dimming of the backlight. Conventional local dimming usually uses one LED as a dimming area of ​​the backlight or multiple LEDs are connected in series and parallel. To form a dimming area, multiple dimming areas are combined with each other to emit a uniform surface light source, but when one of the dimming areas is individually lit, the light emitted by the LEDs in the dimming area will diverge and spread at the ed...
