E-ink in Color

University of Cincinnati researchers have developed an e-ink technology to competently display full color video – but so cheap that it can be completely disposable. Instead of using glass or flexible plastic as the basic substrate layer, they're using paper.

So you could end up with single-page disposable electronic newspapers and magazines that use a tiny fraction of the paper their printed counterparts require.

The paper-based e-ink technology uses the electrowetting method, in which an electric field is applied to colored droplets in a display unit to effectively turn on and off pixels in an array. An electrowetting screen is able to deliver full color, and it can refresh quickly enough to display video.

The end result will be a flexible, very cheap paper screen that can be sold as a disposable item like a newspaper or magazine. You could even print books on it, given a longer-lasting power source.
