Every commercial OLED so far, though, has used indium tin oxide (ITO) as a transparent electrode, which has conductivity issues at low temperatures. But clever researchers at a host of places (Agfa and IMEC of Belgium, Holst Centre, Philips and TNO of the Netherlands) together created an OLED that uses a new transparent polymer called Orgacon, which has up to six times the conductivity of ITO. Even better, the new material is much cheaper to make. The researchers created a prototype OLED lighting panel about the size of a 4.75-inch square. With the new material, you might be able to walk into a store and buy some for a decent price by 2011~
