Abstract
A method of manufacturing a flexible OLED module includes: forming a polymer layer on one surface of a base substrate; forming a thin glass sheet on one surface of the polymer layer; forming multiple OLED elements on one surface of the thin glass sheet; forming a protective layer on one surface of the thin glass sheet to cover the OLED elements; separating the base substrate and the polymer layer from each other through separation of the sacrificial layer by laser lift-off (LLO); and cutting the thin glass sheet and the protective layer to provide multiple unit OLED modules each including the OLED element.
