Engadget has a post up about a new form of reflective display technology called electrowetting, which looks like a very legitimate competitor for E-Ink displays. Electrowetting was invented by Liquavista, which is a venture backed start up created by NVP and Philips Research. The technology works by having a white background covered by a colored oil film, and when a current is run through the display the oil will contract, allowing you to see the white background.
The really exciting thing here is that the response rate is already fast enough to support video. They also designed the technology to fit in with the current manufacturing process for LCD displays to keep fixed costs down. I suspect the downside is that although it will take up less power than an LCD, it will probably still use more than E-Ink. But given battery advancements I'm not sure how much of a problem that is.
They mention planning to use this for portable devices, and although no eReader device is mentioned it is the sort of technology that is capable of making the kind of reader I would want to use.


i have serious doubts that anyone would want to put an "electrowetting" device in their bag much less, god forbid, their pockets...
