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.
