E Ink of Boston announced that it has succeeded in making electronic paper work in full color.



Like ordinary paper, electronic paper works entirely by reflection. This means that, unlike competing electronic displays like LCDs, it never needs a backlight. In addition, it only needs power when the image changes. Once an image has been produced it will remain visible even with the power switched off.



Laptops, palmtops and cellphones with rigid electronic paper screens will be on the market within the next two years
