Abstract
A protected organic light emitting diode includes an organic light emitting diode structure formed on a substrate, a hermetic barrier layer formed over at least part of the organic light emitting diode structure, and a light extraction layer. The barrier layer may include a glass material such as a tin fluorophosphate glass, a tungsten-doped tin fluorophosphate glass, a chalcogenide glass, a tellurite glass, a borate glass or a phosphate glass. The light extraction layer, which may be formed over the barrier layer, includes a high refractive index matrix material and at least one of scattering particles dispersed throughout the matrix material and a roughened surface.
