Abstract

The invention discloses a backlight module, comprising a light guide plate, a light source arranged on the lateral surface of the light guide plate and a back plate arranged on the back side of the light guide plate; and a heat tube unit is arranged on the back plate and is used for conducting the heat dissipated by the light source to the back side of the back plate. By using the backlight module, the heat generated by the light source can be dissipated to the back side of the back plate, the heat can be dissipated to the outside through the surface of the back plate and the temperature of the light source can be effectively reduced; meanwhile, the structure of the backlight module is more compact, which is convenient to assemble the backlight module.

Description

technical field [0001] The invention relates to a backlight module of a liquid crystal display, in particular to a backlight module with good heat dissipation performance. Background technique [0002] Due to the advantages of low operating voltage, low power consumption, flexible display methods, and low radiation, Liquid Crystal Displays (LCDs) are widely used in various fields, such as computers, mobile phones, televisions, and measurement displays. The LCD includes a liquid crystal display panel, and the liquid crystal display panel includes a thin film transistor substrate, a color filter, and a layer of liquid crystal molecules interposed between the two substrates. In addition, the LCD also includes a backlight module, which is used to provide a light source for the liquid crystal display panel, so that the LCD can display images. [0003] At present, the backlight module of LCD includes a side-light structure, which includes a light guide plate and a light source. T...
