Patent ID: 7303324

Claim:
A backlight module comprising: a light guide plate having an incident surface, a first corner and a second corner, the two corners adjacent to the incident surface; a first light source and a second light source, each of the two light sources having an emitting surface, the two light sources being respectively symmetrically disposed adjacent to the two corners of the light guide plate with respect to a middle line of the incident surface; and a first reflector and a second reflector, each of the two reflectors being adjacent to a corresponding light source, the two reflectors being respectively symmetrically disposed adjacent to the incident surface with respect to a middle line of the incident surface, each of the two reflectors having a curved reflective surface facing the emitting surface, the two reflectors being configured for uniformly reflecting light beams emitted from the light sources into the light guide plate through the incident surface; wherein a plurality of microstructures formed on the reflective surfaces of the first reflector and the second reflector, and an angle of inclination of the emitting surface with respect to the incident surface is chosen to be in the range from above about 0 to about 180 degrees.
