Siloxane and siloxane derivatives as encapsulants for organic light emitting devices
First Claim
1. Organic light emitting device havinga) two contact electrodes, one thereof serving as anode and the other one serving as cathode, andb) an organic region in which light is generated by means of electroluminescence if a voltage is applied between said two contact electrodes,being characterized in that at least part of the light emitting portion is covered by Siloxane, said Siloxane comprising an optical element being arranged within the path of said light.

Abstract
An organic light emitting device (10) is provided which is encapsulated by a Siloxane film (17). This Siloxane film (17) is applied to the light emitting portion of the diode (10) providing for protection against contamination, degradation, oxidation and the like. The Siloxane film (17) carries an optical element, such as a lens (18) for example. This optical element (18) is arranged such that the light generated inside the diode (10) is output through it.
