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.
Care to narrow it down a bit? Maybe to the people actually doing the thing?
"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.
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.
Proof?

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.
... in a while.
A) this is not the first time a conductive graphene coating has been shown.
B) It won't revolutionize anything, it's just a very conductive transparent material, like on all LCD screens. It's about cost.
C) Lightest typically means low density, not just small. A single molecule of water is 'lighter' than graphene.
D) At 1nm thick, any material is flexible. The flexibility at this scale depends entirely upon the substrate the graphene is on.
E) While graphene is an excellent heat conductor, the quantity of graphene present means that the thermal conductivity of the material is a negligible component of the overall thermal conductivity of the device.
F) Cost for graphene is NOT based on the availability of the elements used to make it like it is for ITO, it's based on production costs.
Real story: Graphene is very conductive for how thin it is, so a single or few layers are enough to get high surface conductivity while remaining mostly transparent. With well developed processing (this is where the research is currently), graphene is poised to make displays cheaper. Full Stop.
No information on the switching speed.
No information on the pixel density.
No information on the energy consumption.
No information on the reflectivity or whether it's transmissive instead or whether it emits light.
No information on whether it's a straight on-off effect or whether they can do pixel level grayscale.
No description of how it works.
Just descriptions of graphene and the sentence "we used it to make electronic paper." One of the articles did say that their time scale for having a product is "within a year.". I think I'll forget about it until then.
How can Colorado be so careless?
Without "Spring", Colorado only has Summer, Fall and Winter left !

It's in the lab not a product FFS!
If you don't want to read about emerging technology then read other articles.
The first sentence in many Russian articles is "America did something", as you well know, later it is revealed that it was never America or even US government but some company or an individual. Communists always give credit to the whole country, never to individuals involved.
No picture, not even a crude prototype, so in my mind this doesn't actually exist yet.
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?
Actually single atom Graphene was invented in Manchester University UK.

http://www.graphene.manchester.ac.uk/
within a few days of Manchester UNi Patenting the find, China patented derivates. (basically copied in a patent troll kinda way.)
So in 10 years the Chinese will be suing westerner companies for something which was developed in the west.. progress eh!!
So many pop up adverts.....arrgh
I think he is referring to things like this: http://www.bloombergview.com/articles/2013-02-01/piracy-and-fraud-propelled-the-u-s-industrial-revolution
Oh wait, that is the US stealing IP from others.. wrong article..
At least the Chinese don't have individuals like Alexander Hamilton calling for outright IP theft.
--
The most candid mission statement in this regard was Alexander Hamilton’s “Report on Manufactures,” submitted to Congress in December 1791. “To procure all such machines as are known in any part of Europe can only require a proper provision and due pains,” Hamilton wrote. “The knowledge of several of the most important of them is already possessed. The preparation of them here is, in most cases, practicable on nearly equal terms.”
Isn't it funny how there are so many people here against software patents and copyright of music. But when it comes to China all of a sudden they turn a 180 degrees and support IP laws. It's the most hypocritical thing ever.
Also, China didn't steal anything because the idea wasn't even fucking invented yet. So how can they steal something that doesn't exists? Yea, it's possible they took some ideas from the US company, but they actually innovated this time by creating something new. Again, this is what the anti copyright people propose with music, that people should be able to sample and build off each other's ideas (good artists steal, right?) But again when it comes to China, all of a sudden this is not allowed.
Your biases are really starting to show.
Since it's derived from carbon, graphene-based e-papers can be easily produced cost-effectively.
Look, one thing does not follow from the other. Carbon fiber is made from carbon, but it's expensive as hell because of the necessary energy input. So what makes this stuff cheap? TFA doesn't say, either.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Two things. Full color. Video capable update speeds. No? Pass.
Does every book you read have full color and "video capable update speed"? How about signs? Posters? Indicator displays? Meters? Calculators? No they don't. Some applications need color and/or video. Many more do not. It's idiotic and wasteful to insist on technology not appropriate or optimized for a given task.
Seriously, don't be so daft as to think every display needs to be some power hungry 4K color video display. In fact there are a lot of applications where the display you describe would actually reduce its capability. An ebook reader doesn't need color video to display text.
Just another addition to the long list of revolutions that graphene is to bring just about any day now. Apart from graphene itself, the only element in common to all those revolutions in that they seem to languish on the verge of the revolution indefinitely.
Waiter.. The chopsticks with the animated porn advertisements is somewhat distracting! *Credit to Neal Stephenson (except the porn part)*
Have you fscked your local propeller head today?
They are NOT the first. It's already been done.
The following company already did that as a demonstrator.

I'll never fit that in my pocket. I bet Apple will get it much thinner.
