Lack of color in e-paper is still a sore point for many users. Now there is a new light on the horizon, as Japanese electronics giant Fuji-Xerox has displayed a
prototype of electronic paper called "Photo-Addressable Electronic Paper." It uses a cholesteric liquid crystal composition (like
Fujitsu Frontec's FLEPia) in combination with an organic photoconductor. Among the strenghts of this e-paper is high-speed imaging, thin and flexible form factors, non-volatility, image stability against bending, a wide viewing angle, high resolution, and - you may have already guessed it - color.

The integrating sphere reflectance (white) of the electronic paper is 27.4%, and the contrast ratio (the ratio of white color reflectance to black color reflectance) is 6.4. The display is A6 size (105 × 148mm). It is as thin as 0.4mm and can be bent. It weighs 10.4g. For the future, the company plans to develop an A4 size display.

An optical writing system (how it looks and if it's optional we don't know) is used to print on this e-paper; according to the Tech-On reviewer, it takes less than a second to write an A5 page.
Thanks to 13xforever for the news!
