Abstract

The invention relates to a liquid crystal displayer, in particular to a backlight assembly capable of realizing a thin-type liquid crystal displayer, and provides a backlight assembly of the liquid crystal displayer to solve the problems that an existing reflecting film is poor in flatness, and a backlight module is thick. The backlight assembly sequentially comprises a light guide plate, an adhesive layer and a reflecting film, the reflecting film and the light guide plate adhere together through the adhesive layer, lattice points are formed in one surface of the light guide plate, and the adhesive layer is embedded into the lattice points. The brilliancy of the backlight module using the backlight assembly is not reduced, the umbra phenomenon is relieved, the thickness of the liquid crystal displayer is reduced, and the thinning tendency of the liquid crystal displayer is realized.

Description

technical field

[0001] The invention relates to a liquid crystal display, in particular to a backlight assembly for realizing a thin liquid crystal display. Background technique

[0002] A backlight module of a liquid crystal display (LCD) generally includes a transparent light guide plate LGP and a reflective layer under the LGP. Among them, the reflective film in the backlight market is usually a sheet structure, such as commonly used reflective layers such as white reflective film made of PET, multi-layer reflective film and silver reflective sheet.

[0003] Currently, commonly used backlight structures such as figure 1 As shown, there are printed dots 12 on the light guide plate 11, and the reflective film 13 and the back plate 14 are located on the lower side of the light guide plate in turn. The back plate 14 is used to fix the backlight assembly, which accounts for more than half of the thickness of the entire backlight module. There is an air layer between the cove...
