Researchers working on e-paper that lets you watch video

By rapidly manipulating colored oil droplets stacked on top of each other, a new electrowetting (EW) technique could lead to the development of electronic paper displays that can produce high-resolution color video. Displays that use the EW effect could have several advantages over today’s e-readers and other portable flat panel displays, most of which are based on electrophoretic (EPh) technology.

Dr. Han You and Professor Andrew Steckl of the Nanoelectronics Laboratory at the University of Cincinnati have experimentally demonstrated the new display for the first time, with their results published in a recent issue of Applied Physics Letters.
