Abstract

The invention discloses a backlight module which is provided to be combined with a display panel. The backlight module includes a back plate, a diffusion plate, multiple lighting bars mounted on the back plate and at least one lighting module mounted on each of the lighting bars, wherein each of the lighting modules has an LED forward light source and at least one pair of LED non-forward light sources, the pair of LED non-forward light sources is mounted on the side of the LED forward light source, and light emitted from the LED forward light source and light emitted from each of the pair of LED light sources are spliced together to form a diffusing light shape. Therefore, the backlight module of the present invention has reduced lighting bars to decrease the weight, volume and cost of the whole backlight module and liquid-crystal display device, and overcome the problems of non-uniform brightness of conventional backlight modules.

Description

technical field [0001] The present invention is related to a backlight module, in particular to a backlight module that can reduce the number of light strips and light emitting diodes, and overcome the problem of uneven brightness and darkness in existing backlight modules, so as to present a uniform backlight source. Background technique [0002] Liquid crystal display is a kind of passive display device, which does not have the function of automatic light emission, and a light source must be provided separately to provide the display light source required by the display panel. Therefore, in the liquid crystal display, whether the backlight module can emit a light source with sufficient brightness to make the display panel Uniform brightness on the screen will affect the picture quality of the liquid crystal display. [0003] Generally speaking, the backlight module can be divided into front light and back light, and the backlight module can be further divided into side lig...
