Abstract: The present invention relates to a process for laser scoring of flat glass sheets. The process comprises manipulating a laser beam having a substantially Gaussian intensity profile to produce an elongated heating zone on the glass sheet to be scored, the elongated heating zone having a central portion with a lower temperature than a temperature of an outer portion of the heating zone. An initial crack is made in the glass sheet, the elongated heating zone is traversed across the glass sheet coincident with the initial crack, and the heated glass is thermally shocked by directing a cooled liquid against the heated glass, thus propagating the crack. The scored glass sheet may thereafter be broken by applying bending techniques as are known in the art.

Abstract: A method of forming a temporary hermetic seal for an OLED device. The method includes the steps of providing a first glass substrate having at least one OLED device disposed thereon, providing a second glass substrate having one or more frit walls disposed thereon, disposing sealant grease about a periphery of the first or second substrate and joining the first substrate to the second substrate to form an hermetically sealed glass envelop containing at least one OLED device.

Abstract: A glass breaking system is provided for breaking large sheets of glass into small sheets, in which a laser beam having an elongated beam spot shape, with a largest dimension which is at least 20 mm, more preferably at least 30 mm, and most preferably at least 40 mm, is moved across a glass sheet to produce a partial crack score line. The glass sheet is then separated along the score line by applying a bending moment in the area of the partial crack.
