The new feature-enhanced color e-paper developed by Fujitsu Laboratories and to be commercialized by Fujitsu Frontech employs a layered construction found in cholesteric liquid-crystal display (LCD) panels with an image memory function, and makes use of the reflective properties in each color layer where the cholesteric liquid crystals reflect a specific wavelength of light of red, green, or blue
E-paper has some compelling advantages for the next generation of handheld and tablet devices. It provides an image which is very stable and easy to read in comparison to commonly used screen technologies, it consumes negligible power and is lightweight and paper-thin. Color paper arrived in 2007 but it hasn't really been good enough, until now. The principal developer of color e-paper to date has been Fujitsu which has just announced a dramatic increase in color e-paper display quality. The technology will be shown this week at Fujitsu Forum 2010 (May 13 - 14 at Tokyo International Forum) and can be expected in Japanese market e-book readers and advertising billboards by Q3 this year.
