Patent number: 8148179Abstract: A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. In one embodiment, the hermetically sealed glass package is manufactured by providing a first substrate plate and a second substrate plate. The second substrate contains at least one transition or rare earth metal such as iron, copper, vanadium, manganese, cobalt, nickel, chromium, neodymium and/or cerium. A sensitive thin-film device that needs protection is deposited onto the first substrate plate. A laser is then used to heat the doped second substrate plate in a manner that causes a portion of it to swell and form a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the thin film device.Type: GrantFiled: March 17, 2010Date of Patent: April 3, 2012Assignee: Corning IncorporatedInventors: Bruce G. Aitken, Paul S. Danielson, James E. Dickinson, Jr., Stephan L. Logunov, Robert Morena, Mark L. Powley, Kamjula P. Reddy, Joseph F. Schroeder, III, Alexander Streltsov

Patent number: 7770414Abstract: The present invention relates to a process for manufacturing flat sheets of a glass-based material and to an apparatus therefor. The process comprises providing a glass preform, heating the glass preform in a furnace, forming a gob and a pre-sheet, removing the gob and drawing the glass pre-sheet into a flat glass sheet. Also provided is an apparatus for drawing a glass preform into a glass sheet, the apparatus comprising a draw furnace, stretching arms for stretching and drawing the pre-sheet into a glass sheet, and opposing edge rollers for applying a downward force on the glass sheet. The draw furnace may include a plurality of individual heating elements, the temperature of each heating element capable of being separately controlled. The apparatus may further include an annealing furnace for annealing the glass sheet.Type: GrantFiled: May 10, 2007Date of Patent: August 10, 2010Assignee: Corning IncorporatedInventors: Patrick J Cimo, Michael T Murtagh, Mark L Powley
