Abstract
The invention discloses a preparation method of an anti-reflection AR optical film, which comprises the following steps of: 1, preparing a substrate layer, and preparing a thin film from a polymer material through an extrusion molding or tape casting process; step 2, coating ultraviolet curing resin on the surface of the substrate layer, and curing through ultraviolet irradiation to form a hardened layer; step 3, depositing an anti-reflection layer on the surface of the hardened layer through a physical vapor deposition (PVD) process; and step 4, coating the anti-reflection layer with a fluoride material to form an antifouling layer. The invention provides the preparation method of the optical film for the AR equipment. The optical film comprises a substrate layer, an anti-reflection layer, a hardened layer and an antifouling layer, has the advantages of low light loss, low reflectivity, high durability and the like, and is suitable for a display system of AR equipment. The invention further provides a preparation method of the optical film, the process is simple, and large-scale production is easy.
