29 April 2016 Current Affairs: China developed a new electronic paper, which has been heralded as "the world's first graphene electronic paper. It was in news in the last of April 2016.It will be a huge breakthrough that will catapult the material to a new level. It was developed by The Guangzhou OED Technologies in partnership with a company in Chongqing.
Compared with traditional e-papers, graphene e-paper is more pliable and has more intensity and its high-light transmittance means optical displays will be much brighter.E-papers have been produced on a commercial scale since 2014. Compared with liquid crystal displays, e-papers are thinner, bendable and energy efficient, meaning products are more portable.
Graphene : Graphene is the world's strongest and lightest known material; a single layer of graphene is only 0.335 nanometers thick, and it can conduct heat and electricity.The material can be used to create hard or flexible graphene displays, used in electronic products such as e-readers and wearable smart devices.In addition, graphene is derived from carbon, meaning production costs will be much lower than for traditional e-papers, which use the rare, expensive metal indium.
