Patent ID: 7452613

Claim:
An organic electroluminescent device, comprising: a first emissive layer comprising a non-emissive component and a first emissive component, wherein at least one of said first emissive component and said non-emissive component includes at least one of a polymer, polymer blend, and co-polymer, and wherein the other one of said first emissive component and said non-emissive component includes at least one of a polymer, polymer blend, monomer, oligomer, co-polymer, and an organic side-group, and wherein the first emissive layer is cross-linked, said first emissive component capable of emitting light in a first spectrum; a second emissive layer disposed over said first emissive layer, said second emissive layer comprising at least one additional emissive component, wherein said at least one additional emissive component includes at least one of a polymer, polymer blend, co-polymer, or at least one of a polymer, polymer blend, co-polymer in combination with at least one of a monomer, oligomer, and an organic side-group, said first emissive layer is insoluble to the material used in fabricating said second emissive layer, wherein said second emissive layer is capable of emitting light in a second spectrum, further wherein said first spectrum and second spectrum combine such that an output spectrum of said device is white.
