We report improved performance from ITO‐free organic light emitting diodes (OLEDs) prepared with vapour phase polymerization poly(3,4‐ethylenedioxythiophene) (VPP‐PEDOT) anodes. By inserting additional interfacial anode layers based on triarylamine polymers, we demonstrate VPP‐PEDOT OLEDs on rigid glass substrates that display improved electroluminescence characteristics, and which have efficiencies that are comparable to equivalent ITO‐based devices. We also report on the development of flexible OLEDs (FOLEDs) with VPP‐PEDOT anodes, demonstrating efficient red, green, blue and white‐emitting devices with significantly improved device rectification.
