E Ink’s E-Paper Technology

Most of the currently available (and forthcoming) electronic readers use some variety of the electronic ink technology developed by the Cambridge, MA-based E Ink. E Ink’s “electronic ink” is an electrophoretic process; that is, it comprises millions of microcapsules, each about the diameter of a human hair. Each capsule contains a clear fluid suspended in which are tiny black-and-white particles. The black and the white particles each carry opposite electrical charges.
