▎ 摘　　要

NOVELTY - Manufacture of graphene film or pattern involves printing individually graphene oxide ink and reducing agent ink on a substrate, reacting, and forming graphene film or pattern. USE - Manufacture of graphene film or pattern used for active layer for electrode of electric component display device, solar cell, transparency thin film speaker, transistor and chemical sensor (claimed). Uses include but are not limited to liquid crystal display, plasma display device and organic electroluminescent. ADVANTAGE - The method economically, efficiently and rapidly provides graphene film or pattern. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene film or pattern. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the inkjet printing method of the graphene film or pattern. (Drawing includes non-English language text)
