Abstract: An organic electroluminescent device comprises a substrate that supports a first electrode, a second electrode, and a light emitting structure that is disposed between the first and second electrodes. A protective structure comprising a layer of boron oxide and an inorganic barrier layer cooperates with the substrate to encapsulate the first electrode, the second electrode, and the light-emitting structure.

Abstract: Organic electroluminescent device can be formed with multiple layers including an electrode, an emission layer, and a buffer layer. The emission layer includes a light emitting material. The buffer layer is disposed between and in electrical communication with the electrode and the emission layer and includes a triarylamine hole transport material and an electron acceptor material. The buffer layer optionally includes one or more of a) a polymeric binder, b) a color converting material, and c) light scattering particles. The buffer layer can also be formed using a polymeric hole transport material having a plurality of triarylamine moieties.
