Abstract

The invention provides a backlight module, a manufacturing method thereof and a display device, and the backlight module comprises a light-emitting plate, wherein the light-emitting plate consists ofa first basilar plate, a plurality of light-emitting units provided on the first basilar plate and a first reflecting film layer, a first hollow area with multiple array arrangement on the first reflective film layer, the light-emitting units correspond to the first hollow areas one by one and are arranged in the corresponding first hollow areas; a transparent reflection film layer arranged on thelight-emitting plate comprises a transparent film layer and a plurality of second reflection patterns, wherein the transparent film layer is provided with a plurality of second hollow areas arrangedin an array, the second reflection patterns correspond to the second hollow areas and are arranged in the corresponding second hollow areas, and a preset gap exists between the transparent film layerand the light-emitting plate; the light-emitting units correspond to the second reflection patterns one by one, and the orthographic projection of the light-emitting units on the first basilar plate is positioned in the orthographic projection area of the second reflection patterns on the first basilar plate. The integral light-emitting brightness of the backlight module is uniform, the light efficiency loss is reduced, and the power consumption and the thickness of the backlight module are reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a manufacturing method thereof, and a display device. Background technique [0002] The existing backlight module, especially the surface light source formed by Mini LED, is equipped with a direct-type backlight module (Back Light Unit, referred to as BLU) structure, which is convenient for realizing single-point adjustment (Local Dimming) to realize High-dynamic range imaging (High-Dynamic Range, referred to as HDR) display, so that the backlight module has high-contrast rendering characteristics. The reflective surface of the backlight module is currently coated with photosensitive ink, and the reflectivity is only 80%. The light efficiency of the module is low, and the power consumption increases. [0003] It can be seen that the existing backlight modules have the technical problems of low light efficiency and high power consumption. Contents of the in...
