摘要:
A method of controlling the rheology of a sealing glass paste which comprises incorporating a fine inorganic powder in the paste as a mill addition to impart a steep rheology curve to the paste so that the paste resists flow while at rest, but flows readily when shear stress is applied, the amount of inorganic powder incorporated being not over about 10% by weight.

Glassy coatings that isolate metal surfaces from carbon particles, and a method of applying the coatings. The coatings composed of essentially K2O, SiO2, and Al2O3, and has a CTE of at least 80×10−7/° C. These glassy coatings, which adhere well to metals, employ a potassium-silicate glass composition in three forms: a pure glass, a glass loaded with inert filler having a CTE higher than the glass itself, and a precursor frit that when “reactive-cerammed” produces a predominantly leucite crystalline phase and forms the glassy coating in-situ on the metal surface, creating a protective layer between the exposed metal surface and corrosive chemical-processing environments.

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.

摘要:
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.
