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: 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: 6977137Abstract: The invention relates to methods of writing a light-guiding structure in a bulk glass substrate. The bulk glass substrate is preferably made from a soft silica-based material having an annealing point less than about 1380° K. A pulsed laser beam is focused within the substrate while the focus is translated relative to the substrate along a scan path at a scan speed effective to induce an increase in the refractive index of the material along the scan path. Substantially no laser-induced physical damage of the material is incurred along the scan path. Various optical devices can be made using this method.Type: GrantFiled: September 17, 2001Date of Patent: December 20, 2005Assignee: Corning IncorporatedInventors: Nicholas F. Borrelli, Joseph F.
