Color comes to E Ink, LG electronic-paper displays

The first commercial electronic paper displays that can show color were unveiled Wednesday at the Flat Panel Display International show in Japan. The screens open the way for electronic book readers like Amazon's Kindle and Sony's Reader to add color, but so far only a single Chinese device maker has committed to the technology.

Two companies were showing the screens: E Ink, which dominates the e-paper market, and LG Display, which is one of the world's largest display makers. Compared to the monochrome displays used in current electronic book readers, the new displays offer a dash of color, but users shouldn't expect the same sort of color depth and vibrancy that's seen in laptop computers and flat-panel TVs.

Mass production of the 9.7-inch screen, which has an 800 pixel by 600 pixel resolution, is already beginning and E Ink's first customer, Chinese device maker Hanwang Technology, was showing an e-book reader that features the screen.
