Title:
DISPLAY UNIT MANUFACTURING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/117384
Kind Code:
A1
Abstract:
A display unit manufacturing system according to one embodiment of the present invention comprises: a transfer unit for repeatedly transferring, at a predetermined transfer length, and stopping an optical film in which a polarizing film, an adhesive layer, and a release film, which is adhered to the adhesive layer so as to be separable therefrom, are stacked; a cutting unit cutting, along a width direction, the optical film at a predetermined cutting position while leaving the release film, so as to form a slit line on the optical film; a separating unit for separating the release film from the polarizing film; and an attaching unit for attaching, to a panel, the polarizing film from which the release film has been separated, wherein the transfer unit comprises a horizontal roll arranged at an interval from the cutting position toward a downstream side in the transferring direction, and horizontally transferring the optical film, and the horizontal roll can satisfy the following conditional expression such that the slit line is not positioned on the horizontal roll when the transfer of the optical film stops. I * n < H < I * (n + 1), wherein I represents the predetermined transfer length, n is an integer greater than or equal to zero, and H represents a horizontal direction distance between a rotation center of the horizontal roll and the cutting position.
