China Creates World's First Graphene Electronic Paper (techtimes.com) 92
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 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.

On a more serious note, graphene is actually really easy to make. It's just not easy to make in large quantities or in formats that are then easily worked. One of the easiest ways to make graphene can be done right there at your desk. Take a pencil and a piece of tape.Write on the sticky side, go ahead and get a few thick lines on there. Now, over and over again press the tape together so that a non-c

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.

Sharp's memory LCD technology is daylight readable and uses very little power. Not quite as little as e-ink, but low enough that the little solar cells you get on calculators can run them forever. They are fast enough for animation/video too.
The only down side is that they have the same issue as e-ink: patented, single source, not developing very fast and not many different modules to choose from.

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.

Agreed.

Ever since eInk really captured the developer imagination, it feels like it's been some ludicrously guarded secret club to get your hands on a decent unit at a sane price.
Ideally I'd still love to see a reasonably fast refresh (10Hz) 13~15" eInk display.
