Patent number: 8146388Abstract: An apparatus for drawing a glass ribbon including a shroud surrounding the glass ribbon and an edge roll that penetrates the shroud to contact the glass ribbon. The apparatus includes regulating a pressure within the seal assembly to be equal to or less than a pressure within the shroud and prevent ingress of relatively cooler outside gas into the hot interior of the shroud. The edge roll utilizes an air bearing to minimize friction that can produce periodic fluctuation of the ribbon as the edge roll is displaces in response to variations in the ribbon thickness or equipment dimensions.Type: GrantFiled: October 29, 2009Date of Patent: April 3, 2012Assignee: Corning IncorporatedInventors: James G.

Patent number: 8146385Abstract: Methods for separating glass sheets from glass ribbons are disclosed. One method includes forming a glass ribbon having a curvature in a lateral direction. A conformable nosing is engaged with a first surface of the glass ribbon such that the conformable nosing conforms to the curvature of the glass ribbon. The glass ribbon is scored along a scoring line on a second surface of the glass ribbon. The conformable nosing is then at least partially disengaged from the first surface of the glass ribbon by adjusting a bow of the conformable nosing. A bending moment is applied to the glass ribbon to separate a glass sheet from the glass ribbon at the scoring line. Application of the bending moment conforms the curvature of the glass ribbon to the bow of the conformable nosing prior to the glass sheet separating from the glass ribbon.Type: GrantFiled: April 29, 2010Date of Patent: April 3, 2012Assignee: Corning IncorporatedInventors: Julie A.

Patent number: 8132427Abstract: A spray nozzle is used in a process of quenching a hot glass sheet during a laser scoring process or other high energy glass heating process. The scoring is conducted by a high energy means such as a laser. The nozzle is located in proximity to the glass sheet, creating gas in liquid used to quench the glass located in the nozzle (e.g., water). The gas (e.g., air bubbles) is removed from the quenching liquid. Then, the spray nozzle is used to spray the quenching liquid onto the sheet at a location trailing laser scoring of the sheet, such as using a traveling anvil machine at the bottom of the draw. The spray nozzle (purge nozzle) has a purge opening and tubing leading to a discharge location. The purge nozzle can have a sloped passageway that pre-stages gas bubbles near the purge opening in the nozzle. The spray nozzle can include a cooling coil passing around the nozzle passageway that enables a coolant to travel along the coil.Type: GrantFiled: May 15, 2009Date of Patent: March 13, 2012Assignee: Corning IncorporatedInventors: James William Brown, Patrick Michael Gargano, Keith Mitchell Hill, Xinghua Li, William Paul Ryszytiwskyj, Naiyue Zhou

Patent number: 8063560Abstract: A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. Basically, the hermetically sealed OLED display is manufactured by providing a first substrate plate and a second substrate plate and depositing a frit onto the second substrate plate. OLEDs are deposited on the first substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the OLEDs. The frit is glass that was doped with at least one transition metal and possibly a CTE lowering filler such that when the irradiation source heats the frit, it softens and forms a bond. This enables the frit to melt and form the hermetic seal while avoiding thermal damage to the OLEDs.Type: GrantFiled: September 15, 2006Date of Patent: November 22, 2011Assignee: Corning IncorporatedInventors: Bruce G. Aitken, Joel P. Carberry, Steven E. DeMartino, Henry E. Hagy, Lisa A. Lamberson, Richard J. Miller, II, Robert Morena, Joseph F. Schroeder, III, Alexander Streltsov, Sujanto Widjaja

Patent number: 8051679Abstract: Methods of using a laser to separate a glass sheet is presented that employs an elongated and, preferably, asymmetrically-truncated laser beam. The methods allow glass sheets suitable for use in modern display applications to be separated at speeds up to about 200 mm/s with low levels of residual stress, e.g., levels of residual stress which are less than or equal to 100 psi, and preferably less than 50 psi. Glasses with high coefficients of thermal expansion (e.g. greater than about 35×10?7/° C.) may be separated at faster speeds. Such low levels of residual stress translate into low levels of distortion during the manufacture of display panels (e.g., LCD panels) as well as in improved properties (geometry, strength, defect-free etc.) of the separated edges. The methods can be used with glasses of various types including glasses having high coefficients of thermal expansion and also with glass sheets of different thickness.Type: GrantFiled: September 29, 2008Date of Patent: November 8, 2011Assignee: Corning IncorporatedInventors: Anatoli Anatolyevich Abramov, Marvin William Kemmerer, Yawei Sun, Naiyue Zhou

Patent number: 8016009Abstract: An apparatus for sealing a substrate assembly by applying a force to the assembly while simultaneously exposing the substrate assembly, and in particular a sealing material disposed between two substrates of the substrate assembly, to an irradiating beam of electromagnetic energy. The beam heats, cures and/or melts the sealing material, depending upon the sealing material to form the seal. The force is applied by directing a flow of fluid against the substrate assembly, and beneficially improves contact between the substrates of the substrate assembly and the sealing material during the sealing process, therefore assisting in achieving a hermetic seal between the substrates.Type: GrantFiled: December 2, 2010Date of Patent: September 13, 2011Assignee: Corning IncorporatedInventors: Jeffrey Michael Amsden, James Joseph Bernas, John Joseph Costello, III, Margaret Helen Gentile, Mark Andrew Stocker, Lu Zhang
