A backlight module, a display panel, and a display device are disclosed. The backlight module includes 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.

Backlight module, display panel, and display device

The invention provides a light-emitting composite film layer, a backlight module, and a display device. The light-emitting composite film layer includes a quantum dot film layer and a diffusion film layer. The diffusion film layer is disposed on at least one surface of the quantum dot film layer. Quantum dots and light diffusion particles are dispersed in the quantum dot film layer. The quantum dots include green light and red light quantum dots, and light diffusion particles are dispersed in the diffusion film layer. The invention makes blue light divergent, makes the blue light reach same brightness viewing angles as red light and green light, and reduces or even eliminates color cast.
