Bridgestone Shows Off Ultra-Thin, Full-Color e-Paper
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."
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 wouldn't bee too sure. While it will probably be a while before you get HD-video on these things at an affordable price ( 5 years ? ) you really don't need that much in order to browse the web. 5 frames a second would be more than enough to navigate static content, and 24 would be enough for simple animated stuff. Remember that these things don't flicker the same way a CRT does, so you only really need to worry about visual artefacts, like ghosting, which isn't too much of a concern for things that aren't video.
Make clothing from this material and see what it does to fashion! I'm a tech guy and shouldn't be allowing my brain to go here, but imagine: as with your dumb-ass you-paid-$2.99-for-what? ringtones, you'll be able to download patterns for your shirts, slacks and skirts! Hooked up to your cameraphone, hell, you could even be invisible!

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.
So many comments about the small color range, but really this isn't a problem if the dot pitch is small enough. Printed paper only has 8 colors (16 if you include black in CMYB). Back in the day with only 4-16 colors we dithered to get a better range of colors, the look was similar to old comic books and for much the same reason. With 4096 colors to choose from dithering is very subtle and hard to notice. My 1998 laptop monitor only had 4096 colors, but dithering made it look fine. It's unclear to me whether most LCDs even today have full true 24 bit color.

I like where you're going with this. A dual A3/A4 device would be incredibly useful in workplace, where most stuff is printed in A4 but you often need to go to A3 for diagrams (especially Gantt charts).
The beauty of ISO standard paper sizes is that each in the series is exactly half the size of the next largest - i.e. the long edge of A4 is the same length as the short edge of A3. Therefore, if you want an A4 display you unroll your scroll half way. If you want an A3 display then you unroll it all the way.
