It's not a secret that Taiwanese Prime View International (PVI) is the main OEM/ODM supplier of E Ink displays. The Sony Reader is one prominent example using their display design. Now MobileReader lee1234 sent us the news that PVI is also the designer of the E Ink panel that is going to be used in Intel's Metro Notebook. While details are sketchy (http://www.mobileread.com/forums/showthread.php?t=10406) at this point, it appears that unlike the demo device (http://www.mobileread.com/forums/showthread.php?t=10424), the final version of the notebook will feature E Ink in color (as in red-green-blue!!). Quoting Digitimes (http://www.digitimes.com/news/a20070503PD210.html):

The outside display will be made as a colored e-ink screen that shows important content, such as e-mail, calendar entries, eBooks and more, even when the power supply is cut off, the sources noted.

Wow - I like the fact that it requires no actual power "...even when the power supply is cut off" I want one of these zero power requirement devices! (Don't you love marketing :-)

well that's how e-ink works. the display works even with the power supply cut off.
