Abstract

The invention relates to a light source framework and a backlight module. The light source framework comprises a border, an edge strip and a reflector plate, wherein the edge strip is arranged on the border and provided with at least one positioning hole; the reflector plate comprises a first surface and a second surface; the first surface is an optical reflector surface, and the second surface is provided with at least one hook; and the hooks are matched with the positioning holes and used for fixing the reflector plate onto the edge strip. By adopting the invention, the production efficiency of the backlight module can be improved and the production cost is lowered.

Description

technical field [0001] The present invention relates to a light source frame and a backlight module, in particular to a light source frame and a backlight module applied to a liquid crystal display device. Background technique [0002] At present, due to the demand for cost reduction, the side structure of the frame of the liquid crystal display (LCD) direct-lit backlight module is more and more widely adopting the embedded design of black and white two-color materials. See figure 1 and figure 2 , figure 1 is a schematic diagram of a light source frame 10 in the prior art, figure 2 for figure 1 A schematic diagram of the reflective sheet 12 in . The main structure of the side strip 11 on the frame 13 is black, and the reflection sheet 12 is white, which can reflect the light source and improve the utilization rate of light. [0003] In the existing technology, the embedded design mostly adopts the following methods: 1. Two-color integrated injection molding, but the ...
