China develops graphene electronic paper
China has developed the world's first graphene electronic paper that can possibly revolutionize the screen displays on electronic gadgets.
Experts say graphene-based displays would be brighter but also cheaper, as graphene is based on the abundant element carbon.
Conventional e-paper is made of the rather costly rare metal indium. The new e-paper could be used in various types of devices, including wearables and e-readers.
Graphene, which is a single layer of carbon atoms, would enable engineers to make displays that would be extremely thin, light-weight and more durable.
