Abstract

The invention relates to the technical field of liquid crystal display and particularly provides a backlight module. The backlight module comprises a light guide plate, a light source component, an adhesive framework, an optical film, a panel component and a composite heat dissipation part, wherein the light guide plate, the light source component and the adhesive framework are arranged from inside to outside; the optical film is arranged on the upper surface of the light guide plate and is connected to the adhesive framework through an adhesive layer; the panel component is arranged above the optical film and corresponds to the adhesive layer; the composite heat dissipation part is arranged between the panel component and the adhesive layer, extends to the bottom of the light guide plate along the outer side of the adhesive framework and is connected to the light source component. The composite heat dissipation part is used for combining the reflection material with the heat dissipation material; the function of a reflection plate can be achieved; meanwhile, the heat dissipation function can also be achieved; the function of the protection film in the prior art is replaced; the structure of the backlight module is simplified; the thin design of the backlight module is facilitated.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to an improved structure of a backlight module. Background technique [0002] At present, liquid crystal display devices have been widely used in various electronic products as display components of electronic equipment. The frames of these electronic equipment are getting narrower and the brightness requirements are getting higher and higher, and at the same time, they must meet the requirements of power saving; The backlight module is an important part of the liquid crystal display device, and the light incident efficiency of the light bar is bound to be higher and higher. However, the poor heat dissipation effect of the existing backlight module often affects the display quality of the liquid crystal display. [0003] Existing backlight modules such as figure 1 As shown, it includes a light guide plate 1 installed from inside to outside, a light source assembly 2, a plastic ...
