Claim:
1. A quantum dot (QD) backlight module, comprising: a light emitting diode (LED), a reflector, a light guide plate (LGP), a plurality of dot units, and a QD, the LGP disposed above the reflector, the plurality of dot units disposed on an upper surface of the LGP at intervals, the QD packaged in each of the plurality of dot units, the LED disposed on a lateral side of the LGP, semiconductor QD fluorescent powder put in the QD, and each of the plurality of dot units having a cylindrical structure; the LGP comprising a first lateral side and a second lateral side, the first lateral side being opposite to the second lateral side, a thickness of the first lateral side of the LGP being larger than a thickness of the second lateral side of the LGP, and the first lateral side of the LGP being near a lateral side of the LED; the LED emitting light to the LGP, a light emitted by a backlight source of the LED passing through the LGP, the plurality of dot units, and the QD subsequently, the QD transforming the light emitted by the backlight source of the LED to light with diverse waveforms, and the light with the diverse waveforms being emitted outwards, wherein a lateral surface of the dot unit having the cylindrical structure is made of reflective material.
