Nanotech Based Display 217
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 didn't see any mention of this, but considering that they say 'it has the consistency of paper' and the extremely high resolution, if it were touch sensitive, it would replace paper/pencil in a way that PDAs couldn't. I couldn't doodle that well on a palm, but with nanotech resolution and a thin enough stylus, notes on a tablet PC would become a reality.
Just my thoughts on this.

An LCD on the other hand has constant power requirements, even if the image is static.

What I'm wondering about is internal illumination. Does it rely completely on external illumination, or can you fit a backlight into it so you can read in the dark?

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.

Apparently it draws "more" power to change the state of the molecules - due to having to move around charge. Otherwise, the base layer acts as a capacitor, with the stored charge maintaining the on/off state. So you end up spending power mostly on the pixels that change between lit and unlit. Even with full-screen repaints not all pixels switch (think scrolling a page: lots of pixels just stay white between successive repaints) thus you can still get lower power consumption. Of course, for color displays this will probably be less efficient.

The second is usability life. Laptops range from 2 to 4 hours of usable time while reading a text document. Then you have to re-charge it. A book generally never needs to be recharge. It's feasable to take a book and sit on the beach for 8 hours, (I might burn rather sevearly, but that's me) I would not recomend trying that with a laptop. Additionally in this scenario, cleaning the sand out of the book is going to take a lot less effort than doing the same for your laptop.
If the resolution tripples (or more) in each direction, and over the long term takes less energy to display, then we are begining to get to where I would be much happier using such a device than I am carrying around a book. (A novel appropriate fot taking on a vacation can be rather large.
But that's just me. I don't think this is the best that Nanotechnology has in our future. I do think it's one of the better uses for Nano Materials Sciences that have come down the pipeline so far.

It seems to me these guys are already doing this. Perhaps this is competition?

An MPEG decoder card designed for this screen embedded in a purpose built portable dvd player could actually be easier to implement than for a raster screen.
