Graphene Based Display Paves Way For Semi-Transparent Electronic Devices

Posted by timothy on from the looking-through-things dept.

hypnosec writes University of Manchester and University of Sheffield researchers have managed to produce the first graphene-based LED displays, which could pave the way for efficient, flexible and semi-transparent electronic devices. The research, published in scientific journal Nature Materials [abstract; article is paywalled], shows how graphene displays and related 2D materials could be utilised to create light emitting devices for the next-generation of mobile phones, tablets and televisions to make them incredibly thin and durable. The LED device was constructed by combining different 2D crystals and emits light from across its whole surface. Being so thin, at only 10-40 atoms thick, these new components could form the basis for the first generation of semi-transparent smart devices.

    Why do we want semi transparent smart devices?

      I don't know about semi-transparent but flexible so that it doesn't break so easily would be nice.

      We don't. Just like we don't want our coffee makers on the web, or our every online move tracked by companies.

      What makes you think consumer demand matters? Build it, and then manufacture the demand.

      This morning I woke up and knew that getting coffee would be a chore involving going over to the kitchen, setting everything up, waiting a few minutes

      They make coffee makers that you fill with beans and water the night before, and it will grind the coffee and start the brewing so it is ready at a precise time. I have no objection to a programmable device. I even have no real objection to a LAN controllable device. My objection is to a device that connects to the internet. Because that last leap is just to spy on me.

      Or in other words, I've never been on vacation and been like "must make coffee right now."

    For that you don't need a transparent device. You just need a transparent display.

    Those are two different things actually.

    Change Graphene to OLED and you will be able to use all the old news stories from 10 years ago.

      OLED would work well if it didn't have such a bad half-life (at least if the blue component didn't have a bad half-life) which causes the display to turn yellow as it ages. I haven't heard anybody discuss what the half-life of graphene is though, so it could be just as bad.

      We still have to find a cheap, commercial way to produce graphene, so until that happens, the mean life of it it's close to zero.

      Seriously, I'm tired of all these promises of graphene going from curing cancer and HIV to building everlasting batteries out of it to transmitting petabytes of information over a carbon-thick wire... Producing just a small amount of this "miracle material" costs a lot, can't be used out of a lab-controlled environment and it's polluting as hell. Until all of that gets reversed, it's unusable.

    Heads' up displays in cars have been available on and off since the eighties. They're typically projector-based and use glass or an applique on the glass that reflects only where the projector points.

    Did nobody at DICE test the CSS changes? Because the front page is broken on a 960px-wide window now, and it wasn't yesterday. Since that's a window pinned to half of a 1080p screen, and /. doesn't come close to actually needing a full 1920px, I'm sure there's a lot of people browsing the same way, and I'm sure a lot of them won't be browsing back if you keep fucking basic shit up like this.
