China Creates World's First Graphene Electronic Paper (techtimes.com)
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.
The current e-ink market is heavily controlled thus expensive niche items for products that are very cheap to manufacture. We've missed the boat with e-ink phones despite the technology being available for more than a decade - the patent holders didn't want their IP "cheapened" by ending up in inexpensive phones. Hopefully this will open things up a bit. I've wanted an e-ink monitor ever since the technology has been announced but the closest I've been able to get is an android tablet (Boox) and only in the last year.
Indeed...like diamonds.

Why? B/c they are "Chinese"?
Perhaps you should provide some evidence.
:T:R:A:N:S:
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.
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.
Anons need not reply. Questions end with a question mark.

The Chinese likely stole it from one of the numerous and vastly profitable America factories churning out graphene based products. Some new materials turn out to be 100% hype, with no actual applications, but not graphene. We need tariffs against inferior Chinese graphene, to protect American graphene workers from unfair competition.
The market buys a lot of things, such as e-ink readers due to LCD sucking in direct sunlight. If the deliberately restricted market of e-ink opens up a bit due to real competition and is able to actually act like the market you describe then I think there will be room in the market for more devices.
Your snarky "market" comment is amusing considering the topic. Do you really know that little about what has been going on with e-ink for a decade?
