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: 7143609Abstract: A method is provided for molding from glass certain complex optical components, such as lenses, microlens, arrays of microlenses, and gratings or surface-relief diffusers having fine or hyperfine microstructures suitable for optical or electro-optical applications. Thereby, mold masters or patterns, which define the profile of the optical components, made on metal alloys, particularly titanium or nickel alloys, or refractory compositions, with or without a non-reactive coating are used. Given that molding optical components from oxide glasses has numerous drawbacks, it has been discovered in accordance with the invention that non-oxide glasses substantially eliminates these drawbacks. The non-oxide glasses, such as chalcogenide, chalcohalide, and halide glasses, may be used in the mold either in bulk, planar, or power forms. In the mold, the glass is heated to about 10–110° C., preferably about 50° C.Type: GrantFiled: October 29, 2002Date of Patent: December 5, 2006Assignee: Corning IncorporatedInventors: Bruce G Aitken, Dilip K Chatterjee, Daniel H Raguin
