  • Patent number: 10807348
    Abstract: Provided is a system for manufacturing a display unit, the system including: a carrying unit which carries an optical film including a polarizing film including an adhesive layer and a release film to which the polarizing film is bonded to be peeled off through the adhesive layer; a cutting unit which cuts the optical film by a predetermined depth, in which the release film is not cut, and forms a polarizing film sheet piece on the optical film; a peeling unit which peels the polarizing film sheet piece from the release film; and an attachment unit which attaches the polarizing film sheet piece peeled from the release film to a panel, in which the attachment unit includes: a pair of attachment rolls which presses and attaches the polarizing film sheet piece onto one surface of the panel; and a magnetic force generating unit or a suction part, which suppresses an upper attachment roll positioned at an upper side between the pair of attachment rolls from sagging by using magnetic force or suction.

  • Patent number: 10710351
    Abstract: A system for continuously manufacturing an optical display device and methods thereof are described. The system and method include a feeding unit for feeding an optical film, which includes a release film and a plurality of sheet pieces of a polarized film. The system and method further include a peeling unit for peeling the sheet pieces of the polarized film; a winding unit for winding the release film form the sheet pieces of the polarized film; and a controlling unit. The controlling unit controls at least one of the feeding unit, the winding unit, and the laminating unit.

  • Publication number: 20170348957
    Abstract: Provided is a system for continuously manufacturing an optical display device includes: a feeding unit which transfers and feeds an optical film, wherein the optical film includes a release film which is extended in a longitudinal direction, and a plurality of sheet pieces of a polarization film which is arranged in a longitudinal direction and includes an adhesive layer, wherein the sheet pieces of a polarization film is adhered to the release film through the adhesive layer so that the sheet piece of the polarization film is peeled from the release film; a peeling unit which peels the sheet pieces of the polarization film from the release film by folding back inwardly the release film of the optical films fed by the feeding unit; a winding unit which winds the release film from which the sheet piece of the polarization film is peeled by the peeling unit; a laminating unit which laminates on the panel the sheet piece of the polarization film peeled from the release film, while transferring the panel; and a c
