The present invention provides a direct backlight module, which includes a backplane, a backlight source arranged inside the backplane, and a diffuser plate mounted to the backplane and located above the backlight source. The backlight source includes a plurality of LED light bars. Each of the LED light bars includes a plurality of LED lights. The diffuser plate has a light incident surface opposing the backlight source. A phosphor powder layer is coated on the light incident surface of the diffuser plate. The LED lights give off light that excites the phosphor powder layer to give off light. The light given off by the excitation of the phosphor powder layer is mixed with a part of the light emitting from the LED lights to form white light desired for the backlight source. |
