Nanotech Based Display
yodha writes "Ntera showed their NanoChromics Display (NCD) recently. The display uses a nanotechnology process to create a more paper-like image than traditional LCD screen. It delivers significant power savings (they've shoehorned one into an iPod to give people a sense of what it looks like). The image can even remain on the screen for weeks without any power and doesn't need a backlight."
I agree though, it looks like they are having difficulties with the larger screen, as the Ipod screen held the image fine, but the author stated he had to keep refreshing the ebook.
