PHOTOINITIATED OPTICAL ADHESIVE AND METHOD FOR USING SAME
First Claim
1. A method of bonding glass components, comprising:
- providing a mixture comprising two portions which can be combined to produce an adhesive, where at least one of the portions is encapsulated;
applying the mixture to a first glass component;
exposing the mixture to an ultraviolet light source to release the encapsulated portion;
allowing the portions to mix and create an adhesive;
placing a second glass component on the adhesive so as to interpose the adhesive between the first and second glass components; and
allowing the adhesive to cure.

Abstract
A method for bonding glass components using an encapsulated photo-initiated optical adhesive, and the resulting glass assemblies produced by the same. A mixture containing a catalyst and a resin is provided where at least one of either the catalyst or the resin is encapsulated. The mixture is applied to a glass component. The encapsulated catalyst may then be exposed to ultraviolet light causing the capsules to release the portions contained therein and combine to form an adhesive. A second glass component is then placed on the adhesive so that the adhesive is interposed between the glass components and the adhesive is permitted to cure. Alternatively, the mixture may be exposed to UV light after the second glass component is placed. An exemplary method uses a frame with the first glass component to create a uniform thickness of adhesive and provide a low level of optical defects. Barrier coats and skirting tape may also be used.

11. A method for bonding glass components comprising the steps of:
-
providing a first glass component having a first surface; placing a frame around the perimeter of the first surface of the first glass component; sealing the first glass component and the frame with a sealant; allowing the sealant to cure; providing a mixture comprising two portions which can be combined to produce an adhesive, where at least one of the portions is encapsulated; pouring the mixture over the first surface of the first glass component and the frame; exposing the mixture to an ultraviolet light source to release the encapsulated portion; allowing the portions to mix and create an adhesive; placing a second glass component, having a first and second edge, such that the first edge is in contact with the frame and the second edge is elevated above the first glass component; holding the first edge in place while lowering the second edge of the second glass component until the second glass component is substantially parallel with first glass component; and allowing the adhesive to cure. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A front glass assembly for an electronic display, produced by the steps of:
-
providing a mixture comprising two portions which can be combined to produce an adhesive, where at least one of the portions is encapsulated; providing two glass components where at least one of the components has an anti-reflective layer applying the mixture to the first glass component; exposing the mixture to an ultraviolet light source to release the encapsulated portion; allowing the portions to mix and create an adhesive placing the second glass component on the adhesive so as to interpose the adhesive between the first and second glass components; and allowing the adhesive to cure.

22. A glass assembly comprising:
-
a first glass component; a second glass component aligned with and substantially parallel to the first glass component; and a layer of adhesive interposed between the first and second glass components, said layer of adhesive containing remnants of an encapsulating element.
