Abstract
Official abstract text for this publication.
To provide a laminating method which achieve high accuracy and high quality in a laminating step of an optical sheet and a display panel. Contact areas between the optical sheet and the sheet holding head are read. At this time, an optical element face of the optical sheet is brought into contact with the sheet holding head, light is irradiated to the contact areas therebetween from a no-optical-element face, and positional information of the optical sheet is read based on the distribution of the reflected light thereof.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical sheet laminating method which laminates an optical sheet having two sides constituted by an optical element face where a plurality of optical elements are formed and a no-optical-element face where the optical elements are not formed with a display panel by using a sheet holding head, the method comprising: bringing either the optical element face or the no-optical-element face into contact with the sheet holding head; irradiating light to conta…
