  • Patent number: 10197825
    Abstract: A method and an apparatus for manufacturing an optical display device by sequentially peeling a plurality of optical film sheets continuously supported on a long web of a carrier film and laminating the plurality of optical film sheets to a plurality of panel components are provided. After completing laminating operation of a preceding optical film sheet to a preceding panel component, a rear end of next optical film sheet, supported on a carrier film which in a state where one of opposite surfaces thereof is folded to inside at a tip-end of a peeling member, is read at a predetermined detecting position as positional information, then a leading end of an optical film sheet is positioned at a predetermined laminating position based on the positional information while peeling the optical film sheet from the carrier film.
