Problems solved by technology

The side-lit backlight module can solve the problem of thinning, but the light source of the side-lit backlight module can only be set on the side of the light guide plate, so at least one side of the backlight module will be wider due to the light source setting , cannot have the characteristics of a narrow border
At the same time, because the light guide plate is generally heavy and thick, this makes the weight of the backlight module very heavy, and the thickness is relatively thick, which does not meet the lightweight design
In addition, the light guide plate is generally made of transparent plastic, which is prone to problems such as deformation, yellowing and stress concentration, thereby shortening the service life of the backlight module

Abstract

A backlight module includes a back cover, a light source panel positioned on the back cover, a frame connected with the back cover and an optical film assembled to the frame. A pair of reflective plates are positioned between the frame and the back cover, and a plurality of through holes are defined on the pair of reflective plates. A chamber is cooperatively defined between the pair of reflective plates and the back cover, and inner surfaces of the chamber have a high reflectivity.

Description

technical field [0001] The invention relates to a backlight module, in particular to a direct type backlight module. Background technique [0002] With the rapid development of the liquid crystal display industry, the application of various liquid crystal display panels continues to increase, and lighter and thinner products are constantly being introduced. However, since the liquid crystal panel of the liquid crystal display device cannot emit light, a backlight module needs to provide a light source to realize image display on the liquid crystal panel. However, with the rapid development of liquid crystal display devices, the backlight modules used in liquid crystal display devices need to be lighter and thinner. [0003] Traditionally, people mostly use an edge-lit backlight module, including an optical film, a diffuser plate, a light guide plate, and a light source. The optical film is arranged above the diffuser plate, and the diffuser plate is arranged above the ligh...
