20130301240 | BACKLIGHT MODULE - A backlight module including a chamber, a bottom reflector, a plurality of light sources, and a plurality of lenses is provided. The chamber has a bottom surface and a side surface. The bottom reflector is disposed inside the chamber and located on the bottom surface. The light sources are disposed inside the chamber and located above the bottom reflector. Each light source is adjacent to the side surface and provides light. The lenses are disposed on a transmission path of the light. Each lens has a back surface, a cavity on the back surface, and a light-emitting surface. The cavity has a light-incident surface. Each light source is arranged corresponding to one of the lenses and adjacent to the cavity. The light, after passing the lenses, is divided into light beams with different propagating directions. The light beams irradiate the bottom reflector. | 11-14-2013 |
