A prototype Sony organic light emitting diode, or OLED, display is flexible enough to roll around a No. 2 pencil.

The next generation of display technologies promises crisp, bright, colorful images that don't require a backlight -- but they're incredibly expensive and rigid in form factor.

Until now. Sony demonstrated in Japan on Wednesday an ultra-thin 4.1-inch OLED that can roll as tightly as a radius of 4 millimeters and still operate normally -- a world's first, according to the company.

How thin is ultrathin? Approximately 80?m thick, with a resolution of 432 by 240 pixels at 121 pixels per inch.

The roll-up OLED display touts a contrast ratio of 1,000:1 and manages a brightness level of 100 cd/m2.

Here's a look at the amazing display in a video:

  • So when are we going to see this?

    I would love to have digital paper, like they do on Caprica!

  • Everything old is new again, right?

    I hear that scrolls were all the rage in 1200 BC!

    Part of the point is that if it can bend like that, it is unlikely to crack.

  • Dead pixels?

    Does anyone else see the lines of what looks like dead pixels in the screen?

    • Yup. Makes me wonder...

      @jmiller1978

      ...how many roll/unroll cycles before those artifacts started appearing. Of course, this is a prototype so I'd expect them to solve that problem before this tech hit the market.

      Prototype. It might also be the camera filming the video and picking up the flaws with more contrast.

    • It's full of lines, both ways

      It needs a lot of work doing on it before it's ready for the market. But it's still impressive.

  • ...like they do on Caprica

    And cheap enough that you can toss it in the trash after reading what's on it.

    That's cool. For what is an experimental piece I bet the production one will be cool. Yea some dead pixels but it's a proof of concept.

    I see new billboards being made, books being revolutionized with multimedia content, maybe even multimedia wall paper, and extremely flat screen TVs.

    Fantastic, but no mention of how expensive this process is.

      Or the lifespan. That's one hard limit for OLED's right now. I wonder if the scroll gets hot?

  • If this could be made to receive wirelessly

    What a great media idea for newspaper and magazines. I would not want to read everything on an computer, iPad, netbook, etc. There is still something that feels good about holding something that is flexible and reading with it.

    I see proof of concept for picture frame TV. Price will be a factor now fast it will replace LED TV & Computer Monitor.

    Ah now i can read the same newspaper (with different news) everyday...:)

  • Sony being Sony...

    Now if they could only resist tying it to some exclusive/proprietary standard (cough - memory stick - cough).
