New graphene display creates LEDs at an atomic level

Graphene has had a rough go of it of late. After years of breathless reporting on its potential as a long-term solution for logic circuits (computer processors and memory), interest as waned as fundamental research problems have refused to resolve. This doesn’t mean that graphene has no electronics applications, however, and a research team from the University of Manchester has published a report detailing how flexible 2D graphene arrays could be used in the next-generation of LED screens.
