China developed world's first graphene electronic paper

China has developed a new electronic paper, which has been heralded as "the world's first graphene electronic paper.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 is the world's strongest and lightest known material.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.
• Graphene is derived from carbon, meaning production costs will be much lower than for traditional e-papers, which use the rare, expensive metal indium.
