Abstract
The present application provides a backlight module and a quantum dot display device. The present application improves energy efficiency by modifying a backlight of the quantum dot display device. Specifically, energy efficiency of a light-emitting element is improved by adding a small amount of phosphors in the backlight module or setting a diffuser plate as a transparent diffuser plate. In addition, the quantum dot display device provided by the present application not only has a backlight device, but also has a quantum dot film layer and a polarizer.
