An organic light emitting device is provided which includes a cathode ( ), an anode ( ), and an organic electroluminescent region ( ). The anode includes a metal layer ( ), a barrier layer ( ), and an anode modification layer ( ). Light is emitted through the cathode ( ) when a voltage is applied between the anode ( ) and the cathode ( ).

Anode modification for organic light emitting diodes

An organic light emitting device ( ) is provided which is encapsulated by a Siloxane film ( ). This Siloxane film ( ) is applied to the light emitting portion of the diode ( ) providing for protection against contamination, degradation, oxidation and the like. The Siloxane film ( ) carries an optical element, such as a lens ( ) for example. This optical element ( ) is arranged such that the light generated inside the diode ( ) is output through it.

Siloxane and siloxane derivatives as encapsulants for organic light emitting devices

The invention relates to an encapsulated organic light emitting device having an improved protective covering comprising a first layer of passivating metal, a second layer of an inorganic dielectric material and a third layer of polymer.

Encapsulated organic light emitting device

An organic light emitting device (10) is provided which is encapsulated by a Siloxane buffer layer (17.1). This Siloxane buffer layer (17.1) is applied to the diode (10) providing for protection against contamination, degradation, oxidation and the like. The Siloxane buffer layer (17.1) carries at least a second encapsulation layer (17.2).
