E Ink Goes Colour

E Ink, the Cambridge, Massachusetts company behind the Kindle and Sony reader display has taken a big step forward in colour display, reports the New Scientist. Hanvon of China has launched a product using the new colour display.

Unlike LCDs that constantly draw power, electronic ink uses power to change the image – but not to display it – increasing battery life from hours to weeks. Electronic ink works by attracting black or white powders to the front of a clear pixel capsule.
