Coming Soon(ish) From LG: Transparent, Rollup Display 64

jfruh (300774) writes Korean electronics manufacturer LG has shown off experimental, see-through, roll-up displays, paper thin and flexible and capable of letting through about 30% of the light that strikes it. The company is eager to sell the concept and promises it'll be arriving soon, though they've shown of similar (though less capable) technology over the past few years and have yet to bring any products to market.

    From TFA, so it must be true:

    The rollable display sports a 1200x810 resolution with nearly 1 million megapixels.

    I just wish my bank did that sort of math...

  • Scuttlebutt's there's a transparent roll-up display coming soon since, what? Around 2004? Maybe even a bit earlier. OLEDs were supposed to deliver them back in the day. And yet here we are 10 years later, still no transparent roll-up display. Doesn't seem like this should be as hard as a flying car, and yet they both share the same status. I'm sure this one will be different though...
    • Also, there's the unavoidable problem you have with display clarity. Right now screens are on a flat substrate, and so each pixel is aligned with the next one, which reproduces an image accurately. But what happens when you have an unrolled display sitting on your desk, or held in your hand? It will inevitably be have varying levels of curve along it's length and possibly more complex crumples, resulting in poor image accuracy. Fixing that will require some clever sensors embedded in the display along w

  • As one semi famous football player once said. For Who? For What? BTW Can any sports fan guess who said it?

    ..the appeal of a transparent display?

    So I can see what's behind the display? As if we don't have enough issues with sunlight reflecting from display surfaces, now we're going to let the light coming from *behind* the display further reduce its readability?

      Can someone explain the appeal of a transparent display?

      You can see through it. That's very helpful for augmented reality. Being flexible makes it easier to attach to things and being transparent means that you only obscure as much of what's underneath (or beyond if the substrate is also transparent) as you absolutely need to.

      There's lots of potential uses, although pretty much zero of them are on your desktop.

      On the other hand, flexible displays will be useful as soon as we get decent flexible batteries and circuits, just helping us not destroy electronics. Of course, the batteries are only halfway there, and the circuits will be completely throwaway and even more integrated than now. At least some repair is possible today...

    • Duh. Just think how easy it will be to change your desktop background. With one of these all you would need to do is change the poster you placed behind your display with a different poster.

      Car HUD

      • Worse than useless as a HUD. Downright dangerous. A proper HUD is features a collimated display, so you don't have to take focus off your environment to look at it.

    • Augmented reality?

    - Real head's up displays...cars, motorcycle helmets, etc.
    - Leela's arm-puter.
    - Entire glass walls that double as giant displays...like Tony Stark's house.

    and on and on...

    Do what.

      I'm thinking the display could roll up inside of an ink pen like a spring loaded window roller shade. Some enterprising genius could also implement sensors to reproduce script written on paper by the pen to the screen. I'm dreaming of a lot of possibilities.
  • Coming from, where else? Hint: not Apple, but close...

  • Does that mean something like, minimum radius?

  • It's been "coming soon" for nearly 5 years now. They talk about these sorts of displays every year, offer all kinds of compelling demos and then never do anything with it.

      In college my tech Professor asked when we would expect to abandon paper as a reading device, I said when the resolution is indistinguishable and I can roll it up and put it in my pocket, this was around 1992. He offered the opinion it was only 10 years out - there were reports of flexible lcd's even back then. e-Ink screens made me nervous for a while but I'm still clinging to my dead tree novels for now.

      This is a good sign. If someone's showing you technology every year and it's gradually getting bigger and better and eventually starts showing up in products (like LG's TVs) then it's a science and engineering problem that's being advanced. If someone's showing you a technology that never existed before and it's suddenly a whole product, it often means it's so premature it's going to fail and better products will climb over its still-warm corpse towards success, or that it's a scam.

  • ...capable of letting through about 30% of the light that strikes it.

    Does this mean I can finally see my office mate, who is sitting opposite to my desk?

  • This year we get flexible displays ... and with equal probability the Toronto Maple Leafs win the Stanley Cup.

    Promises ... promises

  • If I could only get a 7 or 8-inch tablet with a screen that could be unrolled (and maybe unfolded) to say 16 by 10 inches, I'd be in techietoy heaven. No more squinting at tiny webpage displays, no more squinting at 6-point font displays of books,... you get the idea.

  • Why is it women who are showing off the product?
    Surely they were not involved in the design of this technology.
