NOVELTY - The utility model claims a quantum dot film with waterproof structure, comprising an upper PET layer, a first waterproof layer, a quantum dot layer, a second waterproof layer and a lower PET contact; the first waterproof layer comprises a ceramic layer A and a carbon functional layer A; the second waterproof layer comprises a ceramic layer B and a carbon functional layer B; the ceramic layer A and the ceramic layer B are independently selected from the oxide layer of silicon or the nitride layer of silicon; the carbon functional layer A and the carbon functional layer B are independently selected from graphene layer, carbon nano-tube layer or mixed layer of graphene and carbon nano-tube. The utility model uses the carbon nano-tube and graphene to store the water vapor, which can prolong the service life of the quantum dot film, and the film shape can disperse the heat to be not easy to be concentrated in the local area; The compact ceramic material in the utility model can prevent water vapour, not easy to make the external water vapour enter into the structure to be oxidized through PET. The utility model further claims a backlight module. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a backlight module.
