Abstract:
A light-emitting OLED device that includes one or more light-emitting OLED elements also includes first and second spaced-apart electrodes with one or more light-emitting organic layers formed there-between, at least one light-emitting organic layer being a light-emitting layer. At least one of the electrodes is a transparent electrode. A first hermetic inorganic encapsulating layer is formed over the transparent electrode opposite the light-emitting organic layer. A light-scattering layer is formed over the first hermetic inorganic encapsulating layer opposite the transparent electrode. An organic encapsulating layer is formed over the light-scattering layer opposite the first hermetic encapsulating layer. Finally, a second hermetic inorganic encapsulating layer is formed over the organic encapsulating layer opposite the light-scattering layer.
