Title:
METHOD FOR CONTINUOUSLY PRODUCING OPTICAL DISPLAY PANEL AND SYSTEM FOR CONTINUOUSLY PRODUCING OPTICAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2013/133262
Kind Code:
A1
Abstract:
The present invention suppresses warping of an optical display panel after pasting together while reducing air bubble defects that easily arise between an optical film and an optical cell at the initial period of pasting. The method for continuously producing an optical display panel includes: a carrier film conveyance step wherein a carrier film is conveyed; a peeling step wherein the optical film is peeled from the carrier film; and a pasting step wherein, until a point in time partway from the pasting start time at which the optical film is started to be pasted to the optical cell to the pasting completion time at which the pasting is completed, the pasting speed of the optical film to the optical cell is set in a manner so as to be greater than the speed of conveyance of the carrier film from which the optical film has been peeled, setting is performed in a manner so that after the partway point in time, a period of time is provided during which the speed of pasting and the speed of conveyance match, or a period of time is provided during which the speed of conveyance is greater than the speed of pasting, and the optical film is pasted to the optical cell with an adhesive therebetween while conveying the optical cell, thus forming an optical display panel.
