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.
