Fuji Xerox e-paper tech boasts brighter, more vivid colors

Lack of filter makes for brighter e-paper displays

Fuji Xerox spent the opening day of the Society for Information Display's Display Week 2012 showing off its new color e-paper technology. The new e-paper is said to achieve a brighter, more vivid display due to its lack of a color filter. The technology generates a white screen by drawing all color particles to the back of the display board.

The technology works by establishing a different threshold value for each color in the display. Thus, different levels of charge moving through the display will cause different color particles to be drawn toward the front board to be seen.

Competitors are working on similar technology, such as Qualcomm's Mirasol displays, however the panels have proven to be expensive compared to traditional LCD, AMOLED or grayscale e-ink alternatives. Mirasol has been viewed as inferior in terms of color vibrance, despite its power efficiency (which is comparable to grayscale e-ink, far superior to current color display energy requirements).

Fuji Xerox' technology is still in the prototype stage, and the company says it plans to improve upon it, enabling full-color e-paper using three elementary colors instead of the current two used in the prototype. The five-inch screen size and the 600x800 pixel count likely make the technology unsuitable for use in a mass-consumer device anytime soon.
