▎ 摘　　要

NOVELTY - The quantum dot film comprises a first substrate layer (1) and a second substrate layer (2) that is arranged opposite to each other. A quantum dot layer (3) is arranged between the first substrate layer and the second substrate layer. The components of the quantum dot layer include a mixture (31) of a polymer material fiber and a photocurable glue, and a graphene sheet (32) and a nano quantum dot. The graphene sheets are uniformly dispersed in the mixture. An nano quantum dots (33) are concentrated on the surface of the graphene sheets. USE - Quantum dot film for use in back light module of display device (all claimed) such as LCD and liquid crystal TV, mobile device e.g. mobile phone and tablet computer. ADVANTAGE - The graphene sheet is uniformly dispersed in the mixture, and the nano-quantum dots are concentrated on the surface of the graphene sheet, which prevents the nano-quantum dots from destroyed by oxygen and water vapor. The edge failure of the quantum dot film is effectively prevented. The service life of the quantum dot film is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method of fabricating a quantum dot film; and (2) a backlight module. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of a quantum dot film. First substrate layer (1) Second substrate layer (2) Quantum dot layer (3) Mixture of a polymer material fiber (31) Graphene sheet (32) Nano quantum dot (33)
