        Except that newspapers have a resolution of 200-300 dpi (at 320x240 and 5" diagonal, this device is probably only 72-80 dpi). So, not only is the screen a tad tiny (debatable), it really needs to get up to around 200dpi resolution.

      Actually, the production line they have built can only produce 5000 units per year. As they say, this is more than research, but less than commercial production. Also, this unit only produces black, white, and 4 types of gray. So don't expect to be able to take your pr0n with you on the road just yet in electric, rollable form.

    At least if you've got the paper kind you don't have to worry about it crashing, breaking, running out of power, etc. And with the paper kind, you can easily mark way points, targets, etc in seconds - doing that with a software-based system won't be half as fast.

      One of the major complaints of the troops in Iraq is battery life. Everything has batteries in it. Even the helmets have battery packs.

      GPS was a necessary tool in the dessert. The land is kinda flat and sand colored. All of it. There are no reference points and navigating on land becomes equivilent to navigating at sea. The "map" is a sand colored chart you can plot your points on, not so much a reference you can use to get from one place to another.

      They loved laptops, but only because they could power them from a vehicle. They were issued PDAs but found them fairly useless because the battery life was too short in the field.

      It's the new, high tech army, sponsored by Duracell and the Energizer Bunny.

      There are some obvious advantages to this display. Of course it's light, it uses little power, in some respects it can be used as a chart. You can mark it. It doesn't physically break anymore than a plastic placemat breaks. It's water proof. So long as it get data the single display can be any map the data source has access to so you don't need to be lugging around huge stacks of charts.

      But the biggest thing that negates some of the advantages this display has is that it is inherently static state. That is to say it only needs to be powered to change the display. Not only does that mean very little power drain in use, it means once an image is displayed it can be completely disconected from the power and any other device and the image remains.

      That's pretty frickin' cool.

      I'm already planning (I've already read about this thing) to use a screen like this for the electronic navigation system of a new boat. Take a GPS reading, or display a bit of chart, turn it off and the reading/chart remains. One brief flash of power than off again.

      On the other hand if you think I'm going bluewater without a chronometer and sextant you're nuts. I always expect electronic gear to fail about the second day out. I'm often right.

        Honestly I think that's the major feature. Rolling up a display is nice and all, but the fact that the display will remain without power is incredible.

        We complain that batteries aren't keeping up with technology, but finally there's a technology that will significantly increase battery life.

        I wonder if this could bring back electronic book readers [amazon.com]? They were rather heavy (1.5 lbs) mostly due to requiring a large number batteries to keep it powered for an extended period of time.

        And I'd love to have all my textbooks on one device, even if it cost $500+ that'd be cheap considering a single book is $100+ and you need one for every class.

    I was just thinking of something (I know, scary isn't it). These things will probably be priced reasonably in a short period of time and as Phillips likely hopes will one day replace a good chunck of print media.

    What about disposal? It is likely that if they are priced reasonably enough they may become just as disposable as newspaper (all right, not quite so bad) but even if only one in ten people disposed of these things after they became damaged (look how we treat our newspapers and tell me these things won't be piling up in the dump) how are we supposed to get rid of them? They likely contain a fair amount of material that is not decomposable within a reasonable amount of time. We already know that computers are adding quite a bulge to the normal waste, how would seveal million sheets of this stuff hold up (quite well I'm guessing, probably 100,000 - 500,000 years!)

    This is of course only my perspective but it does give reason to pause.
    • If the companies that make these things really want to win in the public relations field, and they're concerned about the issue you've raised, they could implement some sort of deposit system. You pay a deposit on top of the price of the display that will only be refunded if at the end of its useful life, you return it to the company and get that amount back. Phillips (in this case) could then re-use the components that are salvagable and thus cut down on the amount of waste.

      I know I'm dreaming here, but

      As cheap as paper is, as cheap as this "digital paper" could even hope to be, it's nothing compared to how cheap streaming bytes are.

      Even if buying a newspaper-thick sheaf of this stuff becomes as cheap as newspaper is now, I assure you the economy would rapidly adapt to re-use paper as often as possible.

      Babble about the disposability is more to emphasize how cheap they want to make this, then a true "commitment" to disposing of these things. Economically, we're all going to want to buy as little of this stuff as possible. "Disposing" of this is a pipe dream on the order of flying cars and jetpacks; technically feasible, grossly uneconomical.

      That's not to say that this may not have some impact... but you need not worry about a 1-to-1 replacement of normal paper to digital paper in the landfills. It is quite likely that after a couple of iterations, with "paper" that works for years, that it would cut enough into paper waste to make it an environmental gain.

    This display tech would make a great wrist-wrapping PDA gauntlet. Rather than have to hand-hold the PDA/cellphone/MP3/video player beastie, an arm-conforming design would enable handsfree display. The only decision is whether to wear the display on the top of the forearm (risking damage to the display) or wearing it on the inside of the forearm (which seems a little less comfortable).

  • 2cm bend radius != "roll up into pen" (Score:4, Insightful)

    A 2cm bend radius means that rolled up, this display will form a tube 4cm wide. This is NOT "roll-up into a pen", this is more "roll up into a scrollcase".

    To put in another way: this is a 5 inch diagonal display - say 3x4 inches - that rolls up into a 2 inch wide tube. <sarcasm>Yes, that is a HUGE improvement.</sarcasm>

    WHEN they get this to have a 1mm bending radius I'll get really excited. Until then this isn't all that great, although I suppose a 2 inch diameter by 3 inch long tube diameter tube full of battery and electronics, with a pull-out display might be somewhat useful.

    I've wanted to build a custom portable computer into a staff/walking stick for a while. This would be perfect for the display. A 2 inch curve is about right to wrap around the top of a staff, particularly if it is widened to about a 5 inch circumference at the top.

    Firstly they are making it enough volumes to attract others to build applications that need it, but not enough to generate any real money...But have plans for mass manufacturing plant with 12 to 24 month period from now, but they are seeking funding to build it, which means they have to show SOMETHING, with future potential. They are doing active research, meanwhile which means that they can make it bigger, last longer ,cheaper, and have better resolution, they just don't know yet which of those are going to improve and how much in the period before mass production. The first generation product is probably usably mainly as prototype design and perhaps some rare cases, where cost is not such a problem...

    If you could get these things up to a lifespan of a decade, and get them in colour, you could panel a car with them.

    You could also get by with pixels that are huge - say, 1 cm diameter, and still get some neat effects, like zebra stripes that move along the car in proportion to your speed.

    If they can tighten up the bend radious slighly, and create a 800x600 display at 100 dpi (so it's a 6" display from top to bottom), we will have only one more step to create those GlobalComms from Earth: Final Conflict -- the hardware.

    Might it be possible to include electroplastics in the display substrate? Those materials are manufactured in one shape, returning to it after a mechanical deformation (eg. manual pulling). Additionally, a small applied charge deforms them into another "baked-in" shape; more advanced versions have manifold states, addressable by charge. How about a display that's prerolled into a scroll, then rolled again like a string into a disc, in its uncharged form? A 1" disc might snap into a 15" display on powerup, giving new meaning to "quarter VGA".
