Disclosed is an electronic device comprising a glass, glass ceramic, or ceramic sheet having a thickness less than about 0.4 mm and wherein a minimum strength of the inorganic substrate is greater than about 500 MPa. Also disclosed is a method of making an electronic device including drawing a viscous inorganic material to form an inorganic ribbon having opposing as-formed edges along a length of the ribbon, separating the ribbon to form a substrate sheet of inorganic material comprising two as-formed edges and forming a device element on the inorganic substrate.

Electronic device and method of making

The invention is directed to a method and apparatus for joining together pieces of low thermal expansion glass to form parts that can be used in the manufacturing of mirror blanks. The parts are then used as a basis for the fabrication, using the method described herein, of hexagon sub-assemblies that would then be joined for assembly into mirror blanks.

Method for the joining of low expansion glass

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. The second substrate plate is doped with at least one transition metal such that when the laser interacts with it there is an absorption of light from the laser in the second substrate plate, which leads to the formation of the hermetic seal while avoiding thermal damage to the thin-film device. Another embodiment of the hermetically sealed glass package and a method for manufacturing that hermetically sealed glass package are also described herein.

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.

A birefringent glass composed of a phase-separated glass is provided. The phase-separated glass includes a borosilicate glass in which fluorine and a constituent that tends to crystallize into a high refractive index phase as a consequence of phase separation are included. In one embodiment, the constituent comprises TiO.
