20110049765 | Methods for Laser Cutting Glass Substrates - A method for cutting a glass article from a strengthened glass substrate having a surface compression layer and a tensile layer includes forming an edge defect in the surface compression layer on a first edge of the strengthened glass substrate. The method further includes propagating a through vent through the surface compression and tensile layers at the edge defect. The through vent precedes a region of separation along a cut line between the glass article and the strengthened glass substrate. | 03-03-2011 |
20120135177 | METHODS FOR FORMING GROOVES AND SEPARATING STRENGTHENED GLASS SUBSTRATE SHEETS - Methods for separating strengthened glass articles from glass substrate sheets and strengthened glass substrate sheets are described herein. In one embodiment, a method of separating a glass article from a glass substrate sheet includes forming at least one groove on at least one surface of the glass substrate sheet. The at least one groove continuously extends around a perimeter of the glass article and extends partially through a thickness of the glass substrate sheet. The method further includes strengthening the glass substrate sheet by a strengthening process and separating the glass article from the glass substrate sheet along the at least one groove such that one or more edges of the glass article are under compressive stress. In another embodiment, a strengthened glass substrate sheet includes an ion exchanged glass having one or more grooves in one or more strengthened surface layers, the one or more grooves defining glass articles. | 05-31-2012 |

In one embodiment, a method includes forming at least one series of holes through a thickness of the glass substrate sheet, wherein the at least one series of holes defines a perimeter of the glass panel to be separated from the glass substrate sheet. The method further includes strengthening the glass substrate sheet by a strengthening process, and separating the glass panel from the glass substrate sheet along the at least one series of holes. At least a portion of one or more edges of the glass panel has an associated edge compressive layer. In another embodiment, a strengthened glass substrate sheet includes at least one series of holes that defines a perimeter of one or more glass panels to be separated from the strengthened glass substrate sheet. | 08-02-2012 |
20120216570 | LOCAL STRENGTHENING OF GLASS BY ION EXCHANGE - This disclosure describes a process for strengthening, by ion-exchange, the edges of an article separated from a large glass sheet after the sheet has been ion-exchanged to strengthen by exposing only the one or a plurality of the edges of the separated article to an ion-exchange medium (for example without limitation, a salt, paste, frit, glass) while the glass surface is maintained at temperatures less than 200° C. | 08-30-2012 |
