Abstract
Organic light emitting devices (OLEDs) having improved outcoupling efficiency by using a discontinuous layer made of a translucent low- index material. Examples of low- index materials that can be used include inorganic alkali metal salts, such as LiF. The discontinuous layer (18) comprises discrete elements that are not connected to each other. For example, the discontinuous layer may be formed by depositing the low- index material to form islands instead of a continuous film. An organic layer (16) (e.g., a hole injection layer) comprising an organic material is disposed on the discontinuous layer such that the organic layer is in physical contact with the discontinuous layer. The discontinuous layer and/or organic layer may be designed to improve light outcoupling while minimizing any increase in electrical resistance or loss of active light emitting area caused by the discontinuous layer.
