Abstract:
1. A method of manufacturing a flexible display substrate having reduced moisture permeability and reduced oxygen permeability, on which an organic device is mounted, the method comprising: uniformly dispersing at least one of, nanosized or microsized particles in a molten polymer matrix; forming the molten polymer matrix dispersed with the at least one of, the nanosized or microsized particles into plate-shaped molten polymer, and extruding the plate-shaped molten polymer between two extruding rollers to form at least one of, a polymer or a plastic sheet, to orient the at least one of, the nanosized or microsized particles in parallel with a surface of the at least one of, the polymer or the plastic sheet; stretching the at least one of, the polymer or the plastic sheet between a glass transition temperature and a melting point to form at least one of, a polymer or a plastic film, exfoliating the at least one of, the nanosized or microsized particles, and orienting the at least one of, the nanosized or microsized particles further in parallel with a surface of the at least one of, the polymer or the plastic film; coating the at least one of, the polymer or the plastic film with an organic film to flatten a surface of the flexible display substrate; and performing heat treatment to cure the organic film.
