New Sony OLED Display Can Roll Into Cylinder 73

Anarki2004 writes "Sony recently debuted its latest in OLED technology: a 4.1-inch screen that's only 80 microns thick. The super-flexible display can roll up into a cylinder just 4mm in diameter while still showing moving images at 432×240 resolution. Instead of brittle integrated circuit chips, the screen has an on-panel gate-driven circuit — a world first, according to Sony. That innovation would allow everything but the power supply to roll and flex in applications."

    Good thing, too - you wouldn't want to roll up the power supply, shove it in your pocket, and have it burst into flames. After all, "It's a SONY!"

        ... and if you make it round, you can wrap the screen around it ... Quick, patent round batteries! Oh, wait a sec ...

        My friend told me about this device that powered things without a battery, all you had to do was turn a handle. I thought to myself, that's got to be some sort of wind up.
        • Yeah but the problem is that while they could make circuits in the screen, they certainly can't duplicate chipmaking control, efficiency and accuracy on the flexible substrate. So yes, you could have your next phone rollable, if you would accept a 6 Mhz cpu with 2 Mb ram.

      Bah, just when I was thinking that if it's this thin and flexible, they could put it on a condom and give you the choice of what to display on it (like, say, a $100 bill or a credit card for wives who won't touch anything else of their husband's)... you just have to come and give me the mental image of it bursting into flames.

      I think power technology is gonna be the easy part here. Big thick (think fancy home-audio ribbon cables) copper ring around the outer perimeter of the device, with 50 or 100 turns of spiral around the outside. Suddenly every movement through the device's Z-axis generates magnetic flux. Mobile devices might self-charge if they consume little enough and the EM environment is noisy enough. The recharging 'docking station' could just be a little induction coil that you leave the device on top of or near.

    But when are they going to be able to make 40" TV's that are affordable with OLED? (Hell, I thought a few years ago the shtick was that they could print them out so cheaply you would just make a new OLED every so often if anything went wrong with the screen.)

    OK so I imagine that the technology doesn't really fit well with touchscreen designs. That's fine though: I want a device like the HTC Evo with a nice sized touchscreen in the portrait orientation but a roll-out OLED in the landscape which would become a widescreen for video. I'm thinking like 3.5" normal 'portrait' screen and a 8" roll-out widescreen... if they can figure out a way to keep it pretty sturdy when rolled out. That'll be a challenge IMHO.

      Not much of a challenge at all. I can think of three ways, with varying costs, weights, and effectiveness. I'm sure the engineers involved will do better.

      • Really? I can't think of many. The length of the screen would prohibit the use of simple rails that slide out of the body of the phone... they'd be much longer than the phone's width. I imagine that some kind of one-way-bendable rail that can roll up with the screen could work but that would be a pretty delicate thing and if you tweaked it at all you might be pretty pissed when your screen doesn't roll back up..

      • The actual prop must have had a workable rail, even if it didn't have a real screen.
      • I was wondering if I was the only one who remembers (or will admit to having watched) Earth Final Conflict. The only good thing that really came from that show was the communication devices - they pulled the screen from a cellphone sized object to make a reasonably large full-video screen (like pull-down blinds).

        The power supply doesn't need to by flexible to solve the old problem of balancing phone/device screen size with overall size when you're not using it.

    I'd love to have 3x9" phone with a long edge that could pull out a scrolled up display to a full 8.5x11".

    Even cooler would be if the scroll could "telescope" out like a radio antenna before scolling, so a few 3" segments could snap out to 8.5", and scroll out to 11". That extensible scroll could contain an 8.5x11" screen in a 3x3 package. Perhaps even a 0.5" thick package, if the scroll can roll really tight.

    A real pocket sized phone with a real fullsized display on demand. Cool!

  • I'm fed up with all the baseless hype Sony keep generating around OLED. Sony have been showing various "in the lab" examples of flexible OLED screens for years. Decades even. OLED TV has become the "Duke Nukem Forever" of TV tech.

    I'll only pay attention to any more new OLED stories when someone makes home-sized (52 inch+) OLED TVs at affordable prices (i.e. same price as LCDs) actually available for purchase.
