China has developed a new electronic paper, a huge breakthrough that will catapult the material to a new level.
The new material has been heralded as "the world's first graphene electronic paper," by Chen Yu, general manager of Guangzhou OED Technologies, which developed it in partnership with a company in Chongqing.
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.
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.
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. 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. The team's graphene e-paper will be put into production within a year.
