An LCD Built with Graphene

Ultrathin flakes of carbon may offer advantages over indium tin oxide.

Hank Hogan

According to a team of researchers from the UK and Russia, thin sheets of carbon could improve LCDs. The group recently demonstrated that graphene — a two-dimensional layer of carbon — can be used to make the conducting transparent thin films required as electrodes in LCDs and other photonic devices. The insets show two stages of an LCD built using graphene instead of the commonly used indium tin oxide for one of its electrodes. The graphs show the normalized transmission — as a percentage of the maximum — versus the voltage applied to the electrode. As with other LCDs, the transmitted...Read full article
