1000 color EFD e-paper developed

This has popped up on Scientific American among other spots

Quote:
The current generation of e-readers doesn't make good use of ambient light (making them less energy efficient and more difficult to read in sunlight), and few can reproduce full-color copy. This could be changing now that a team of engineers has developed a new prototype electronic paper that can rapidly reveal or hide enough pigments to form 1,000 different colors, paving the way for, among other things, more vivid e-book readers that will also be able to play video.

The prototype is an "electrofluidic display" (EFD) that uses voltage to pull water-based spots of colored ink out of a reservoir in the center of the screen's pixels and spread their colors over those pixels, which are coated with highly reflective aluminum, according to the researchers, led by the University of Cincinnati's Novel Devices Laboratory in paper published yesterday on Nature Photonics's Web site.

...

While Novel Devices Laboratory's prototype EFD can reflect about 55 percent of ambient light (more than any other e-reader screen currently on the market), their goal is to create a screen that can reflect 85 percent of available light.
E-Ink, Sony, IRex, and Fijutsu are mentioned in reference to other existing technology.

that sounds amazingly like the B&W InkWell technology discussed in this thread
