China Creates World's First Graphene Electronic Paper (techtimes.com)

Posted by BeauHD on from the thinner-lighter-stronger dept.

An anonymous reader writes from a report published on Tech Times: China has developed the world's first graphene electronic paper that can possibly revolutionize the screen displays on electronic gadgets such as wearable devices and e-readers. Developed by Guangzhou OED Technologies in partnership with another company in the Chongqing Province, the material is also the world's lightest and strongest material in prevalence today. It's 0.335 nanometers thick and can be used to create hard or flexible graphene displays. Graphene e-paper comes with the capability to conduct both heat and electricity, and it can supposedly enhance optical displays to a brighter level, owing to its high-light transmittance properties. What about cost? Since it's derived from carbon, graphene-based e-papers can be easily produced cost-effectively. Traditional e-papers use indium metal for their display, which is very expensive and rare to source.

    "What about cost? Since it's derived from carbon, graphene-based e-papers can be easily produced cost-effectively". The source element has little to do with the cost to manufacture.

      Indeed...like diamonds.

      Graphene is not exactly "in prevalence" yet. All we can do is produce experimental scraps of it.

      It's a given that everything is expensive when it's new, so I think the unspoken (and kind of obvious) point is that as manufacturing technique improves, there's a very long way that price reduction can go. This will never be true of rare natural resources, however.

    Why? B/c they are "Chinese"?

    Perhaps you should provide some evidence.

    There are a lot of applications where both of your criteria are not needed.
    Do you really need to play movies on the wall panel that tells you what the airconditioner is doing?

    i'm looking forward to cheap epaper for stuff because the current e-ink clowns refuse to work with anyone that isn't a multibillion dollar company.
