ABSTRACT:
A method for hermetically sealing an organic thin-film light-emitting device between a substrate and a cover including the steps of bringing the substrate and cover into close proximity at a peripheral side edge of at least one of the substrate or cover, bringing an energy absorbing material into contact with the cover and substrate at the peripheral side edge of at least one of the substrate or cover, and applying energy directly to the energy absorbing material, causing the energy absorbing material to transfer heat to the substrate and the cover to fuse and form a hermetic seal along the peripheral side edge.
