Abstract

We report large area gravure-printed flexible and transparent polymer electrodes for plastic electronics and in particular their application in organic light-emitting diodes (OLEDs) for displays and lighting applications. The polymer electrodes are prepared from vapour-phase polymerised p o ly (3,4-ethylene-dioxythio - phene) (VPP-PEDOT). Gravure printing has been selected for this work owing to its proven compatibility' with low-cost and high volume roll-to-roll manufacturing. The printed VPP- PEDOT thin films were characterised for their conductivity, transparency, work function and surface roughness. After optimisation of printed VPP-PEDOT thin film transparent electrodes, large area ITO free OLEDs were demonstrated.
