Abstract
A method of encapsulating organic electroluminescent (EL) devices including providing an EL device on a substrate and a metallic sheet having a stand-off structure depending therefrom, the stand-off structure bounding a cavity larger than the EL device. The stand-off structure is positioned over the EL device with the EL device nested within the cavity. The metallic sheet is adhesively bonded to the substrate at a perimeter outboard of the stand-off structure to seal the organic electroluminescent device in the cavity. When a plurality of EL devices are manufactured on a single substrate, the metallic sheet is perforated at the perimeter of each device so that excess metal can be separated and the substrate separated to provide individual EL devices.
