A quantum dot backlight module includes: a reflector, a light guide plate disposed above the reflector, a plurality of dot units disposed on an upper surface of the light guide plate at intervals, and a quantum dot packaged in each of the plurality of dot units, and light emitting diodes disposed on a edge side of the light guide plate. According to the present invention, the quantum dot material can be used less, which is good for reducing the production cost. Besides, heat can be effectively radiated from the light emitting diodes. Wide color gamut is realized as well. |

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. |
