Description

technical field

[0001] The present invention provides a back light module, especially a back light module with high heat transfer rate. Background technique

[0002] Backlight module is one of the key components of liquid crystal display products, and has been widely used in digital cameras, digital personal assistants (PDA), satellite navigation systems, computer monitors and flat-screen TVs. Generally speaking, the backlight module is arranged under a display panel, and has a light source and a diffusing plate, so as to provide a uniformly diffused light to the display panel, and then control the display panel On the pixel electrode to form the appropriate image. Among them, the backlight module can be divided into direct illuminance backlight module whose light source is directly below the display screen or edge light backlight module with light source near the side of the display screen according to the location of the light source. . Since the direct-lit backlight mo...
