Abstract
A backlight module includes a light source, a waveguide, a reflector, and an optical film. The waveguide includes a light inlet surface facing the light source, a light emitting surface adjacent to the light inlet surface, and a bottom surface opposite to the light emitting surface. The reflector is disposed under the bottom surface of the waveguide. The optical film is disposed above the light emitting surface of the waveguide. The reflector is coated with a gradation color layer composed by yellow graduating to blue so as to ensure projection of light from the light source is homogeneous with reduced chromatic aberration.
