Zusammenfassung:	An exemplary backlight module ( 200 ) includes a light emitting unit ( 220 ). The light emitting unit includes a plurality of light sources ( 227, 228, 229 ) configured for providing color light beams respectively, and a mixer ( 222 ) configured for mixing the color light beams into white color beams. The mixer includes a plurality of light guide structures ( 223 ) respectively corresponding to the light sources and a mixing body ( 226 ) connected to the light guide structures. The light guide structures are configured for guiding color light beams emitted from the light sources to the mixing body. The color light beams emitted from all the light sources being partially mixed into white light beams in the mixing body.
