ABSTRACT:
A backlight system (100) in accordance with the present invention includes a plurality of light sources (110) for emitting light beams and a light guide plate (120) for receiving the light beams emitted by the light sources. The light guide plate includes a light input surface (121) and a light output surface (122) joining the light input surface. The light input surface has a plurality of protrusions (124) thereon. The light beams are refracted and diffused by the protrusions, and are then transmitted through the light guide plate to be emitted with a high degree of uniformity through the light output surface.
