NOVELTY - The utility model claims a liquid crystal display screen backlight module, comprising a fixed bottom frame; the upper surface of the fixed bottom frame is fixedly installed with a transverse protective edge; the upper surface of the fixed bottom frame is movably installed with a fixed upper frame; the middle position of the upper surface of the fixed bottom frame is fixedly installed with a light guide layer; the lower surface of the fixed bottom frame is fixedly installed with an aluminium radiating layer. The liquid crystal display screen backlight module of the utility model can ensure the fixed upper frame and the fixed base are accurately attached, and simplifies the mounting operation, at the same time, ensures the stability of the whole structure, the integrity of the backlight module is stronger, but also enhances the flexibility of the processing; capable of uniformly absorbing the heat of the light emitting module on the fixed bottom frame through the aluminium radiating layer; matching the graphene radiating layer and the copper radiating layer for radiating; improving the radiating performance by three-layer radiating design; prolonging the service life of the backlight module.
