Abstract
A method of applying optical film to a large format display panel is described. The method utilizes optical film (20) that has been pre-cut to cover a given area of the panel, such that the film does not need to be cut or trimmed after it is adhered to the panel. The method is suitable for use with large format display panels such as those having viewable areas of 208 cm (82 inches) diagonal.
Claims25
A method of applying an optical film to a large format display panel, comprising:
- (a) providing a large format display panel having a diagonal of at least about 432 mm (17 inches);
- (b) providing a pre-cut laminate comprising
- an optical film comprising an adhesive layer disposed on an optical substrate, and
- a release liner disposed on the adhesive layer opposite the optical substrate;
- (c) separating the release liner from the adhesive layer to expose a portion of the adhesive layer, the exposed portion comprising less than 25% of the total area of the adhesive layer;
- (d) contacting the exposed portion of the adhesive layer with the display panel;
- (e) further separating the release liner from the adhesive layer to expose a remaining portion of the adhesive layer;
- and
- (f) contacting the remaining portion of the adhesive layer with the display panel such that the optical film covers at least 95% of the display panel;
- wherein the method is carried out without liquid.
