1. A backlight module, comprising:
a light-emitting diode (LED) light source; and
a quantum-dot-brightness enhancement film disposed on one side of the LED light source;
wherein the quantum-dot-brightness enhancement film contains a resin system of blue phosphor and red-and-green quantum dots, the blue phosphor is used as diffusion particles to prevent agglomeration of red-and-green quantum dots, and a part of blue light emitted by the blue phosphor stimulates the red-and-green quantum dots, the blue phosphor is selected from one of BaMgAl14O23:Eu, BaMg2Al16O27:Eu, and Al7O3N5:Eu, or any combination thereof, and the red-and-green quantum dots are selected from one of ZnCdSe2, Cd2Sse, and Cd2SeTe, or any combination thereof.
