Researchers from Sweden and the US have produced a new transparent lighting component that is made from Graphene. They say it is cheap to make and fully recyclable, and might be an alternative to OLED Lighting. The new device is called an Organic Light-emitting Electrochemical Cell, or LEC. The Graphene is used for an electrode. LECs can be made using a roll-to-roll process, because all of its parts can be made from liquid solutions.

There's very little info on that new device (such as what is the actual light-emitting material, what's the efficiency of it, etc.).
