Abstract

The invention discloses a backlight module. The backlight module comprises a backboard, at least one light source and a net-shaped diffusion structure. The backboard comprises a bottom plate and a plurality of side walls connected to the bottom plate, and a containing space is defined by the side walls and the bottom plate. The net-shaped diffusion structure is arranged above the containing space and comprises a plurality of transparent cables, the transparent cables are interwoven to form a plurality of grids, and the net-shaped diffusion structure has different cable distribution densities in different zones. By means of the backlight module, the material using amount can be reduced, the requirement for the thin backlight module is met, and the manufacture procedure can be simplified.

Description

technical field [0001] The invention relates to a backlight module. Background technique [0002] figure 1 It is a partial cross-sectional schematic diagram of a known backlight module. Such as figure 1 As shown, the backlight module 100 has a backplane 102 , a light source 104 and a diffusion plate 106 confined in the backplane 102 , and at least one optical film 108 is disposed on the diffusion plate 106 . Because the diffuser plate 106 of the known backlight module 100 is a plate-shaped solid structure with a certain thickness, it cannot meet the current demand for lighter and thinner backlight modules. [0003] Taiwan Patent Publication No. TW201024809A discloses a diffuser plate, which includes a light emitting surface, a light incident surface, a plurality of main linear protrusions and a plurality of secondary linear protrusions. The light-incident surface and the light-exit surface are arranged oppositely, and the light diffusing ability can be improved by mixing...
