  Electrowetting Promises Power-Sipping, Daylight Readable Color Displays

Dutch researchers are working on a new application of an old technology that could mean bright color displays that draw much less power than conventional LCDs, according to the BBC. In this application, an instance of a technique known as electrowetting, droplets of colored oil in suspension are the basis for the display's colors; each pixel's color is determined by moving the colored oils with electrical current. A prototype reader from Dutch firm Liquivista is shown in the accompanying video; color magazines with 50-60hz refresh time using this display technology are at least a few years out, though. Significantly, these screens are daylight readable, which makes me wonder how they compare to Pixel-Qi style screens in power draw, brightness, and maximum density.
