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.

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

      Yep, it works.

      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.

    So you can see the chips and battery inside of it ?

    Good frigging question

    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."
