Prototype Rollable Paper-like Display Ready Early 267

freitasm writes "A few months ago Philips promised a rollable, paper-like display in two years, but it only took them a few months to have a prototype ready. From the article: 'The Readius is the world's first prototype of a functional electronic-document reader that can unroll its display to a scale larger than the device itself. With four gray levels, the monochrome, 5-inch QVGA (320 pixels x 240 pixels) display provides paper-like viewing with a high contrast ratio. Once the user has finished reading, the display can be rolled back into the pocket-size (100 mm x 60 mm x 20 mm) device.'"

    From the article: With four gray levels, the monochrome, 5-inch QVGA (320 pixels x 240 pixels) display provides paper-like viewing comfort with a high contrast ratio for reading-intensive applications, including text, graphics, and electronic maps.

    This is the type of screen resolution for my Digital Reader, the resolution that made me send it back the day I got it. There's nothing paper-like about reading dot-matrix like resolutions. The eye doesn't adapt but instead becomes increasingly fatigued.

    This technology may have some application for computer-like applications. I was hoping for e-books. This screen resolution won't cut that....

      There was a time when the best personal computers had screens of that quality. But over time the technology develops, and things will improve. While not perfect, I would hardly suggest that this technology is useless. It is merely a stepping stone to far greater achievements.

        Yes, but the difference is that producers of four greyscale monitors actually sold units which gave them money to do development to produce more capable monitors. These guys, on the other hand, are likely going to not bother trying to get sales until they have a 256 greyscale display and then they'll charge too much for it to try to make up their development costs and the technology will fade into obscurity.

          It depends on application. If you had read the article, you'd have seen that they do not intend to market the thing directly, but rather
          the Readius was created in order to demonstrate the viability of the rollable-display concept in mobile applications and to gain customer feedback at the IFA 2005.
          There are things that could benefit from this kind of advancement, even at the current state of things: GPS devices, for example, and even cell phones: even though these days we're used to colorful thingies which can do everything but guarantee you can make phone calls, there some of us (*raises hand*) which want nothing more than the ability to make phone calls and write and read SMS. The ability to do it on a wider screen extensible on purpose would be an extremely nice thing. Think about a one- or two-lines display that can roll up to enclose an entire SMS or addressbook without the need to scroll.

          Another major selling point could be the ability to stay 'on' the whole time while still sucking up less battery. How much battery is sucked up by current displays? After all, there is a reason why all cellphones have screen savers or at least the ability to choose for how long after the key presses the display has to stay bright. Of course you might not be able to use your cellphone or iPod as nightlamp anymore ...

          While an extensible, always-on display could be a selling feature of some such portable device (oh yeah, did I mention portable music players?) it would still need to be priced reasonably. In-between the current B&W braindead displays and the current fancy color displays of phone-cams.

      • Yeah, but why is display technology moving so slow? I can't find a non-laptop 17" LCD monitor that can do 1600x1200. And 1600x1200 has been around for ages. I don't need fast 3D graphics or anything, I'd just like some detailed screens where i can't count then number of pixels in the non-antialiased white '/' character on a black terminal. which appears to be 10, on this computer's xterm.
    • Just like generation 1 computer screens...useless resolution, any color you wanted as long as it was amber or green. Look what they've evolved into.

      Give it time. This is "the world's first prototype".

    • It's a prototype. What do you want? It's not ready for prime time!

      Do you really think they would say "paper-like display in two years" and then throw something out in two months, and put it on the market? It will still be two years before something like this hits the shops.

      It all depends on the specifics of the device. I'ved used a Handspring Prism [pdasupport.com] with a resolution of only 160x160 for years for an ebook reader, and it's great. I've gone through quite a few, especially from Baen [baen.com]

      It ends up with a column width around that of an article in a newspaper or magazine, and is quite readable. Even when only using a limited number of colors (default fonts are only 1-bit) ti works well. I think much of it is due to having a white background. So the reflective properties and contrast of the display itself could make a huge difference.

    • Forget the resolution, look at the picture -- this stuff is much greyer than even newsprint. There's a reason real paper is white and so much money and effort goes into bleaching wood pulp to make it that way: the contrast makes it easier to read and reduces eyestrain.

        This comment and the parent comment frustrate me. They are short-sighted criticisms of a fundamentally new technology. I've held samples of this technology in my hand, and its potential is staggering. Sure, the current prototypes are a bit crude in terms of contrast and resolution, but these are engineering issues that will go away with time and more R&D money.

        The two key features that make this a revolutionary new display technology is that it is thin and flexible (and can be manufactured and processed as giant sheets) and that it is bi-stable, meaning once you set the image it takes no power to retain that image. These two features are unlike any other display technology we have today, and unltimately will define the applications it is appropriate for. This really does have the potential to radically change periodical print media, personal printing, and poster/billboard advertising.

        In the future, I would encourage you to learn a little bit more about a new technology before saying it sucks.

        • Well you're partly right however this is only a consequence on the press release. I'm sorry but 320x200 on a 5 inch screen is really far from "paper-like" viewing. Laser printing got a par with classical printing when it reached 600dpi. So I doubt you can get "paper-like" without at least 300dpi and a really high contrast.

      If you look at this picture [polymervision.com] the display actually looks quite readable with quite a few lines of text. I imagine in a few years they will double the pixels, increase the contrast and use font smoothing to make it all the better.

      And I too have read ebooks on a smaller 320x240 display and found it easy enough to keep using 5 hours+ in a row during reading sessions.

    Cool prototype and proof of concept, but is it ready for primetime with the specs? Four levels of gray are good for text, but poor for B&W photos and certain types of graphs. I'm not trying to denigrate it as an achievement, but as a product... I have some issues with it. Until it can do more shades and possibly a higher resolution, would it be more than a status gadget?

    • It will be ready enough for the applications that need it -- they'll be willing to put up with the high price/features&quality. Later it will get cheap and be everywhere.

      Just about everything you use started out really pricey and flaky -- but then got cheap and reliable.
    • Since it's only a prototype and not a product, and since they still have most of the two years until product release left, I'm guessing Philips does not see it as ready for primetime.

      I'm really excited about reflective (vs emissive, like color LCD) displays though. Computers just won't work well outside dimly lit offices until reflective displays are practical. Think about a large-screen TV with NO brightness issues; you want it brighter, just shine a lamp on it (like a painting).

      From the picture it seems to just give devices the ability to expand the screen out so you can have a very portable device with a large screen.

      So think of a mobile phone sized device that can expand out to screen size of a PSP (or something like that). Then give that screen touch pad or stylus abilities, and a powerful CPU and you have an ultimate generic portable PC with game, mp3 and organiser abilities.
