China Develops World’s First Electronic Paper Based on Graphene

China has made a breakthrough in the electronic paper segment. According to Xinhua, Guangzhou OED Technologies has developed a new technology described as "the world's first graphene electronic paper". OED Technologies collaborated with a Chongqing-based company to create the electronic paper.

In comparison to regular e-papers available currently, graphene e-paper is more capable of high-light transmission. This can result in better quality optical displays. This paper is also more flexible and shows more intensity.

Graphene has many characteristics which make it a suitable material for e-paper. It is strong yet is extremely lightweight. The material is also known to be a good conductor of electricity and heat.
E-paper is used in many modern electronic gadgets including smart devices and e-readers. It is more economical and efficient than liquid crystal displays. E-papers are generally more energy efficient, pliable and thinner.

Graphene based e-paper is likely to be more economical than traditional e-papers, which are made using a more expensive metal, indium. Graphene, on the other hand, is made from carbon, which is readily available and cheap.

The new graphene-based paper is expected to disrupt the sector as its cost efficiency, and higher utility factor will make it more amenable to be used in various devices. This may also help in rationalizing the manufacturing costs of new age screen-based gadgets.
Guangzhou OED Technologies is expected to start production of graphene e-paper within a year.



China develops graphene electronic paper


GUANGZHOU -- 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.
