Abstract

Gravure contact printing is the highest volume, large area printing technique known. It is ideally suited for the fabrication of large-area polymer light emitting diode (PLED) based lighting, backlights and displays. Here we show how gravure can be used to fabricate the poly (3,4-ethylene dioxythiophene) : poly(styrene sulfonate) hole injection layer and the light emitting polymer emissive layer in a conventional PLED, as well as the cesium carbonate electron injection layer in an inverted PLED. The performance equals or exceeds that of devices where these layers are deposited by conventional spin-coating.
