Abstract
The present disclosure discloses a quantum dot enhancement film and a manufacturing method thereof, as well as a quantum dot backlight module and a display device. The quantum dot enhancement film includes an optical film, a perovskite quantum sphere molecule which is coated on an optical film and includes a nano-scale spheres doped with perovskite quantum dots, perovskite quantum dots are combined through a chemical bond and doped on a surface of the nano-scale spheres. By the above means, the stability of the quantum dot enhancement film is enhanced. In addition, the quantum dot enhancement film adopting the perovskite quantum sphere has high quantum efficiencies and color gamut, greatly improving the display effect.
