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.
"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.
They stole the design from a team in Colorado Springs, because that's what China does. They steal and steal and steal some more.
TFA: "It has been developed by Guangzhou OED Technologies in partnership with another company in the Chongqing Province."
Why? B/c they are "Chinese"?
Perhaps you should provide some evidence.

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.

It's in the lab not a product FFS!
If you don't want to read about emerging technology then read other articles.
Perhaps you should provide some evidence.
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 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.
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?
I agree, this is totally unfair! My uncle works in a graphene mine and he might lose his job now.
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.
Try learning a little more about the 19th C before sticking your foot so firmly in your mouth.

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.

Hmm... I don't know, I don't think that sentence looks good on me.
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-covered section gets stuck with the covered section and then peel them apart. Do that over and over again. You've got graphene in short order. Really, you'll have graphene in just a few minutes.
Now, there are much better processes but I'm told that none of them are great for making it in quantity or in an easily worked form. I guess, we could hire a bunch of Chinese people and give them all a roll of Scotch Tape and some pencils but that's not going to get us very far. I'm not sure what improvements have been made in the past 18 months or so. Hmm... Maybe two years? I've not read of anything popping up on the production side - but I do read about a lot of theoretical uses that are right around the corner.

Hey KGIII, the other thread is closed, so I'm replying here. Did you ever make it to Cuba?
"Guangzhou OED Technologies in partnership with another company in the Chongqing Province" isn't good enough for you?
Downmodding is the refuge of the weak. Don't downmod, make a better argument!
