  • Organic light emitting device, method for producing thereof and array of organic light emitting devices
    Patent number: 8212269
    Abstract: The present invention is directed to an organic light emitting device (OLED) including a first electrode, a second electrode, at least one layer of organic material arranged between the first electrode and the second electrode, and a dielectric capping layer arranged on the second electrode opposite to the first electrode, wherein the capping layer comprises an outer surface, opposite to the second electrode, for emission of light generated in the at least one layer of organic material. The capping layer has the effect that a reflectance of external light is reduced whereas outcoupling of the light generated in the at least one layer of organic material through the capping layer is increased.
