Abstract
The present invention provides a direct backlight module including a backplane, backlight sources arranged inside the backplane, and a diffusion plate mounted to the backplane and located above the backlight sources. The backplane includes a bottom plate, side plates connected to the bottom plate, and mount units formed on the bottom plate and each having first and second slope surfaces that are inclined in opposite directions. The backlight sources are respectively mounted to the first and second slope surfaces, whereby the backlight sources are set inclined with respect to the diffusion plate in order to increase the distance available for light mixing, improve intensity and homogeneity of illumination, and at the same time reduce the quantity of LED lamps used to reduce the manufacture cost and facilitate size thinning of the backlight module.
