Abstract
Disclosed is an organic electroluminescent device, comprising: a) a substrate; b) a first electrode disposed over the substrate; c) a composite light emitting layer comprising two or more light emissive materials, disposed over the first electrode; and d) a second electrode disposed over the composite light emissive layer, the electrodes commonly and singularly addressing the composite light emissive layer.
Claims24
An organic electroluminescent device comprising:
- a substrate;
- a first electrode disposed over the substrate;
- a composite light emissive layer, disposed over the first electrode, said composite layer comprising a first light emissive material patterned by at least one additional light emissive material emitting in a different spectrum than said first light emissive material;
- and
- a second electrode disposed over said composite light emissive layer, wherein said second electrode and said first electrode are common to and address the entirety of said composite light emissive layer.
