Patent ID: 7527418

Claim:
A backlight module, comprising: a light guide plate comprising a light incident surface and a light emitting surface; a plurality of light sources adjacent to the light incident surface; a frame configured to receive the light sources and the light guide plate; and a colored reflective structure disposed in the frame, being made of colored reflective material that generates reflected light beams having corresponding color according to the light beams it receives, a density of the colored reflective material progressively decreasing with an increase in distance between the colored reflective material and the light incident surface of the light guide plate; wherein some of the light beams emitting from the light sources transmit through the light guide plate to the colored reflective structure and converted to reflected light beams having a corresponding color, the reflected light beams mix with other unreflected light beams in the light guide plate and generate mixed light beams having a desired color, and the mixed light beams emit from the light emitting surface.
