▎ 摘　　要

NOVELTY - The film has a graphene sheet placed in a mixed solution to form an anti-reflective mixed solution. The anti-reflective mixed solution is coated on a substrate. The anti-reflective mixed solution performs alignment treatment by using a magnetic field to deflect the graphene sheet in the anti-reflective mixed solution to a predetermined angle. The anti-reflective mixed solution is cured to form an anti-reflective layer on the substrate. The substrate is placed in the magnetic field. The substrate is adjusted multiple graphene deflection direction of the magnetic field. Angle of rotation of the magnetic field is formed between 90 degree to 170 degrees. USE - Optical film for display panel (claimed). ADVANTAGE - The film forms an anti-reflection layer with a graphene sheet on a substrate. The graphene sheet reduces reflection of ambient light when ambient light is irradiated to an optical film so as to improve anti-reflection capability of a display panel, and improves contrast of the display panel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing optical film of display panel. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of an optical film for display panel.
