Abstract
A reflecting apparatus for a backlight module of a plane display is disclosed. The backlight module includes a light guide distal from the reflecting apparatus, and a plurality of diffusers. The apparatus comprises a light source, a reflector, and two substantially parallel sets of partially overlapped light deflectors wherein a gap exists between either two adjacent light deflectors of the same set or one light deflector and the reflector. A portion of emitted light is directed to the light guide after being reflected from the reflector. The remaining portion of light is directed to the light guide either after it has been deflected by the light deflectors or deflected by the light deflectors prior to being reflected by the reflector. Parallel light received at the light guide is deflected to the plane display as a backlight source of the plane display after passing the diffusers.
