Bridgestone Shows Off Ultra-Thin, Full-Color e-Paper 177

Bridgestone, the company which debuted the "world's thinnest" sheet of two-color e-paper last year, has turned around and delivered a new version which is capable of displaying over four thousand colors. "In case that wasn't enough, the company is also touting what it calls the "world's largest full color e-paper that is A3 size, which is equivalent to a 21.4-inch screen." As you'd expect, the latter is expected to be used solely for advertising and could hit the market as early as next year, while the former technology is set to be commercially available in 2009."

        To make high-quality analog reconversion more difficult, the manufacturer can have the e-paper display turn off while exposed to light that's as bright as a flatbed scanner's lamp.
        • I thought one of the main selling points of e-paper was that you could read it just as well in bright sunlight as in normal interior lighting. Texas summer sun is probably brighter than a scanner's lamp.

          As I understand it, part of why everyone is so excited about e-paper is that the image remains on the page when the power is no longer being applied. So, the fail-proof way around ANY e-paper DRM is just take out the batteries before you photocopy/scan it.

            Not if they make the paper sensitive to high intensity light. Put a disclaimer on it that says "Don't put this into a photocopier, or expose it to high heat/light....

          That would require some form of brightness sensor that a)would drive up costs and b) could be easily defeated by just taping over the seonsor area. Covering the whole of the reading area with tiny sensors seems a little like overkill (not that this would ever have stopped DRM proponents, but still).

          You could use just about any kind of halfway decent digital camera to take long exposures (when I say long I mean 1/5 of a second or so.) You get the same image as then scanner and there would be no way for the E-paper to tell what was soaking up all the photons that were reflected off of it.
        • A better solution would be to space the dots in order to generate a Moire pattern when the image is scanned or photographed.
          • Of course, you would only get the moire pattern if the resolution of the scanner/copier was worse than the display...
            • Well, actually, if the resolution of the scanner/copier was not significantly greater than that of the display. But it's a good point, all the same.

      I would love to have an A3-sized e-reader for schematics. Having the ability to search my documents (where is R217?) without having to deal with the cumbersome laptops with small displays, would be great. I imagine a scroll with the batteries and processor in the center, or a folding book. Either way you would have the option of using it in A3 or A4 size depending on what you need to do. It wouldn't need a huge amount of memory, especially if it had WiFi. It wouldn't need a high a refresh rate or many colors - I could get by with monochrome, 16 colors would be nice, 256 would be exorbitant. Just high resolution PDF view and file browser and I'd be happy. Bonus points for excel documents.

    • I beg to differ. Consider all the tree paper being used in photocopiers each year. What if a new system were put in place where a photocopier could output images to re-usable e-pages? So instead of throwing out the old memos, you recycle them in the machine. This could save huge amounts of money. Also consider fax machines. Though outdated by email, they are still used widely but are inundated by spam faxes. But if fax sheets were recyclable, this would reduce the amount of ink and paper thrown out. Bridge
    • It seems to me that refresh rates are not too important when it comes to the major advantages of electronic paper, namely that (1) it is eventually going to be a great replacement for many uses of normal paper, and (2) it only consumes energy when the image is refreshed, so a single battery charge can be used to view static text and images for a long time.

    ...can you bend the critter (or at least build it as a wrap-around type screen), without optical distortion (or at least some sort of compensation against it by a GPU)? It would add one hell of a dimension to gaming, simulators, immersion-type entertainment, things like that.

    I realize it's probably possible to do when building it, but it takes a pretty (relatively) hefty chunk of time to do anisotropic conversions of flat images (e.g. when creating image-based lighting maps for CG artwork raytracing and such), but if that could be fixed, a semi-spherical screen with the focal point being a person's head would be hella nice.

    (of course, they'd still have to add about 15.9-something million colors in capability and perhaps a tighter resolution to it as well, but still... looks like it could go to some interesting places if they actually get it working).

      Well, in one year they have advanced from 8 color (1 bit RGB) to 4096 color (4 bits RGB). That's pretty good considering they have to create a high resolution flexible display A3 size. By next year, they probably will have 8-bit RGB, and in the future maybe even 16-bit channels, which would be good enough for photography. Just make sure the top of the display is glossy and it will look like a magazine.
