The Stanford University have successfully developed a new concept with a few nanometer of graphene as transparent conductor for OLEDs.They demonstrate organic light-emitting diodes with solution-processed graphene thin film transparent conductive anodes. The graphene electrodes were deposited on quartz substrates by spin-coating of an aqueous dispersion of functionalized graphene, followed by a vacuum anneal step to reduce the sheet resistance.

Swedish and US researchers have developed a new lighting technology that could lead to innovations like illuminated wallpaper made entirely of plastic and cheaper, more easily recycled electronic devices. This new super material is called: graphene.

Organic light-emitting electrochemical cell (LEC). It is inexpensive to produce, and the transparent electrode is made of the carbon material graphene.
