The Fraunhofer Institute, Germany, has announced that a team of its researchers have been able to create electrode for OLED (Organic Light Emitting Display) using graphene.
The electrodes (see them in the picture) have an area of 2×1 cm. The innovation is in the process "invented" to create the graphene electrodes. The researchers blow a a mixture of methane and hydrogen on a copper plate that has been heated to 800°C in a void. This starts a chemical reaction resulting in the formation of graphene (one atom thick layer…) on the copper surface. This is pretty fast, just a few minutes. Once the graphene layer has been created they cover it with a polymer that is used for transporting it and dissolve the copper plate.
Although this is a research result (funded by the EU in the cooperative project Gladiator aiming at creating industry viable processes to manufacture graphene) researchers expect that industry can start manufacturing graphene using this process as soon as 2019.
For its strength and flexibility graphene electrodes will be ideal for touch screen, so we can expect them in our hands in the next decade.
