Abstract: 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.

Abstract: An improved filling material for a composite solder glass based on doped PbTiO3 is disclosed, in which up to 35 atom % of the Pb atoms and up to 35% Ti atoms are replaced by Mg and/or Ca and a portion of O atoms in the doped PbTiO3 is replaced with halogen atoms, preferably fluorine atoms. This filling material and composite solder glasses containing it are useful for hermetic sealing, soldering and/or coating of individual components made of glass material, glass-ceramic material, ceramic material and metal in the manufacturing of components and devices for electrical engineering and electronics, for hermetic encapsulation of electronic components, vacuum-tight seals or closures of display tubes or for display devices. They are also useful for coating and bonding of special glasses. The filling material can be made by reaction sintering of a powder mixture at temperatures of 800° C. to 1250° C.
