BACKLIGHT MODULE
First Claim
1. A backlight module, comprising:
- a housing comprising a reflective coating located on an inner surface of the housing;
a light source received within the housing and for providing light beams;
a light guide plate received within the housing and for converting the light beams into corresponding surface light source;
a diffuser plate received within the housing and mounted on the light guide plate, the diffuser plate for unifying the light beams from the light guide plate; and
a prism plate received within the housing and mounted on the diffuser plate, the prism plate for increasing illumination of the light beams, wherein parts of the light beams are reflected by the reflective coating back to the light guide plate, and the reflected light beams pass through the diffuser plate and the prism plate.

Abstract
A backlight module includes a housing, a light source, a light guide plate, a diffuser plate and a prism plate, and the light source, the light guide plate, the diffuser plate and the prism plate are received within the housing. The housing includes reflective coating located on an inner surface of the housing. The light source provides light beams; the light guide plate converts the light beams into corresponding surface light source. The diffuser plate is mounted on the light guide plate and unifies the light beams from the light guide plate. The prism plate is mounted on the diffuser plate and increases the illumination of the light beams. Thus, parts of the light beams are reflected by the reflective coating back to the light guide plate, and the reflected light beams pass through the diffuser plate and the prism plate.
