LCD Screens Almost Paper-thin

DarklordSatin writes "Nature.com has an article up about new LCDs that are thin enough to roll up and can display black and white at 96 dpi. More coverage by Wired and Scientific American. Thanks go to Arstechnica for the heads up." Wow. Let the speculation for new uses begin! Update: 05/10 14:59 GMT by CN : Whoops, this is really a dupe of an older story that slipped through because I only searched for LCDs. Ah well, it's still cool.

      How about a wireless pocket sized computer, something like that that Personal Server Intel touted a while back. You could use a thin-film flexible circuit and transceiver to "talk" to it. Super-thin touchscreens won't be too far off either. Then you can add wireless broadband 'net access to the Personal Server, and you've effective got the world in your pocket.

      Agreed..

      I work in a job as a Computer Technician, and people keep saying to me they really want to get an LCD screen 'because it looks cool' - fair enough I suppose, but why pay for a 17" mid range LCD screen over a 21" Natural Flat top of the line CRT monitor? Ok, it saves on some desk space..

      Its a no brainer for me.. i'd still put my money on CRT every time.

      LCDs allow your working space be more changable. This is the same reasoning behind Apple making desktop computers easier to carry; you don't want to be chained to the same desk. Plus, LCDs are much better on the eyes -- if you really start using them, it's painful to go back to CRTs.

      The ratio might come down once US manufacturers also start figuring the cost of recycling into the price. In Europe it is mandatory for computer makers to take back their old stuff, and recycle it in a reasonable way, as opposed to the US where most old computers end up in basements or landfills. Of course, it makes prices higher but in the end, everybody wins.
      And recycling a CRT is much more expensive than recycling an LCD, so the price difference is smaller.

    At a refresh rate of 4Hz, it's not much use as a monitor, I think they currently use this stuff for signage displays and the like. It might be useful for a e-book sort of thing, where it's unlikely you'll be reading faster than four pages a second.

    The big question is how much does it cost and how durable/stable is it?

    Maybe it's just me, but I've been visiting slashdot for 3+ years now, and I keep seeing articles about new, paper thing, cheap displays that will revolutionize everything, and really small, cheap, huge(storage capacity), solid state storage devices.

    I look forward to new stuff as much as anyone, but in those 3 years, hard drive storage and monitors keep making slower (in comparison to what is mentioned in articles such as these), but steady process.

    I no longer trust articles saying 'everything will be different in a year.' From my experience, it won't be different and revolutionary, it will just be slightly better.

    1. Re:Is it just me? by MikeFM · · Score: 3, Interesting

      I usually see these new tech articles and think to myself "Wow, things will be really different in 5-10 years." Asking for it to change dramaticly in even 2-3 years is asking a lot. Also as you say a lot of the changes are incremental so you fail to notice they are taking place. It's now pretty affordable for the average yokel (me) to have a terabyte of disk space at home, a tiny computer that is quiet, a nice lcd screen, and broadband. For the most part 3 years ago that stuff was available but cost a lot more. These new technologies are creeping out the door - mostly being sold to other companies - but they are emerging as real products. They still tend to cost a lot and be hard to find but they are showing up.

      Also it should be noted with development guys that they either take one of two personalities.. the cautious "It'll be ready in 30 years." guys and the gungho "Tomorrow we're all going to have jet packs." guys. Obviously the later make more interesting news sources because only ubergeeks plan 30 years into the future. I guess I'm both. I'm very gungho about what I'm doing now but am already looking into what I might be working on in 30 years. Nobody quotes me for articles though. :)

    Walls covered with these displays on the inside that can display anything. No need for windows, just make the displays show what's outside. The appearance of glass walls without the privacy issues. The only thing missing will be natural sunlight and opening a window for a breeze. But you can make any s**thole apartment seem to be a cabin in the woods, or beachfront property, or floating 150 miles above the planet's surface.

  11. Why not an electronic newspaper? by Oculus+Habent · · Score: 5, Interesting

    Sure, you can't fold it, but you could roll it up in to a 1" tube that contains batteries, communications, etc. Carry a 1-foot long 1" diameter tube that rolls out into a 19" screen. And it could be much smaller if you wanted.

    This would be perfect for "paperback" e-books. Even with the quarter-second refresh time on the screen it would acceptable for "turning the page". Or you could produce a book of the screens, and have the pages fill in with whatever you are reading.

    How about electronic blueprints? Dynamic wall art that you can move around easily? Status displays on pillars in the airport?

    If they can reduce the refresh time it would be incredible. Imagine a roll-up 19" screen for crowded server closets.

  12. My Use for This... by naelurec · · Score: 5, Interesting

    I am a musician (pianist) ... Currently I play at a church and for each service, I have to pull music from 5 different books + sheet music, etc..etc..

    Needless to say, first, its a pain to carry around those books with me, flipping through them during a service, finding particular songs, etc...

    So back in 1999 when I bought my Visor Deluxe PDA, I thought it would be cool to scan in all of that sheet music and have the PDA hooked up to some e-paper sheets (probably two of them) and then use a foot switch to "turn the pages" ..

    The setup would be very cool, small and portable. Before a service, I'd simply download the lineup into the system and everything would be ready to go. No carrying around the books, no page flipping, etc.. Heck .. given the way I play the piano (music laying flat on top of the piano), it could possibly make it look like I memorized all the music to the congregation :-)

    Of course, I heard about e-paper back then as well.. and so far, no products.. so by the time it *IS* released, i might already use something like a tablet PC ....

    The two goals, which in my mind are separate directions, are speed and independence from wires.

    If I can 'print' an e-book, I don't care about refresh rate. But is a 300-page e-paperback cheaper than buying, say 50 paperbacks? 20 paperbacks? Or is it silly to even think of having 300 pages of this stuff, and I'd just 'leaf' through pages like I do on my PDA currently? Maybe I'm old, but I still like the page-flipping aspect of books, especially if I want to flip back to find when a character that just stepped out of the wings first showed up.

    If this stuff is as durable, and as cheap, power-friendly and fast as LCDs, I'd be happy to drop a fair chunk of my PDA's weight. Cell-phone screens sound like another perfect application.

    Now for the more far-out stuff:
    How about rewritable MTG cards?

  17. Folding, bending. by j1mmy · · Score: 4, Insightful

    The point of these displays (as stated in the article) is to create a one-page newspaper. They can currently roll it up pretty well, but it can't be folded. What I want to know is why you would fold it.

    If it's a one-page newspaper, you've only got one page. It can be the size of an 8.5x11 piece of paper. It's an entirely different presentation medium and they're still thinking in terms of traditional papers. The biggest failure of the traditional newspaper (as an interface) is that you have to do all the folding and whatnot. Most papers can't be held with one hand without folding them up a bit. It's a hassle, plain and simple.

    If you've got one sheet of electronic paper, of a reasonable size, you can hold it in one hand and just read it.

    I can see how folding would be useful for storing the paper, but I don't see that as a critical issue.

    Basically, it is 2 XGA displays at 180dpi that doesn't require refresh, so can last a few months on 2 AA batteries. It reads contents stored on an SD card. The weight is only 500 gram. I like physical books compared to bulky PDAs with small screens, but something like this could become serious competition to them.
