  • Patent number: 7903199
    Abstract: An exemplary backlight module (40) includes a number of point light sources (43) and a light-mixing member (47). The number of point light sources emit light beams of different colors. The light-mixing member mixes the light beams of different colors into white light beams. The light-mixing member includes a light entrance surface (470) opposite to the light sources. The light entrance surface includes a number of recesses (471). The recesses correspond to the number of point light sources. The backlight module has high efficiency of light mixing.

  • Patent number: 7463316
    Abstract: An exemplary backlight module (12) includes a light guide plate (15) and a light source (17). The light guide plate includes a light incident surface (152), a top surface (154) connected with the light incident surface, and a bottom surface (156) opposite to the top surface. The light source includes an illuminator (172) located adjacent the light incident surface, and a light source reflector (19) cooperating with the light incident surface to generally surround the illuminator. The light source reflector includes a top plate (194) abutting a first end portion of the top surface of the light guide plate, and a bottom plate (196) abutting a second end portion of the bottom surface of the light guide plate. The bottom plate is narrower than the top plate.
