On this diagram the olpc-Display
seems to have different performance-characteristics in “black and white /reflective mode” in comparison to the new PixelQi-Display.
What are the differences between those two displays,
responsible for this improvement in “black and white /reflective mode”?
Thanks, Vincent
answer: The pixel qi screen is entirely new (we have many patents pending on the new architecture), but the result is much higher performance

I wonder if the diagram means that Pixel Qi is slightly worse than what they use in modern eBook readers.
And BTW, will Pixel Qi support sub-pixel anti-aliasing in reflective mode? Not that I cannot live without it, but still it would be nice.
answer: we have higher power consumption than electrophoretic technology, but the vast majority of power consumption in a screen comes from it’s backlight, with it off, the power savings are dramatic. Backlight can be turned off in room lighting and outside (the screen is sunlight readable). Of course anti-aliasing and sub-pixel rendering are supported. We are slightly dimmer than electrophoretic in dim room light, but in these cases the backlight can be turned on to the lowest setting (very low power) and the effect - the screen appears similar to electrophoretics - with the majority of light reflecting off the screen. In a totally dark room, the pixel qi screen can be seen and read using the backlight feature, unlike electrophoretics.

What amazed me about the XO’s screen was it’s high resolution in grayscale mode. I believe it calculated to be around 200 DPI. How does the new Pixel Qi screen compare to the XO’s screen in terms of DPI? Are you looking into increasing the DPI towards print-quality in future products or are you limited by conventional manufacturing techniques?
Thanks,
Brian

What about source of backlight - are You aiming in LED or CCFL?
Is Your main goal to provide the best readability and paper like perfomance?
And most of all - what about other than netbook screen size, like 14′,15,4, 19, 21, 24 inches?

So I guess for Winter Holidays/Xmass Your displays will be available for customers?

@foxcatalyst
“Our _first_ screens will be 10″ diagonal screens for netbooks”
I guess that means that if everything works out, there will be other screens.
@brianpeiris
“The epaper mode has 3 times the resolution of the fully saturated color mode”
Given that modern netbooks’ DPI is already a hundred and something, I guess we’re going to get much more than 200 DPI.

And never mind my question about font anti-aliasing. At 300-400 DPI it probably doesn’t matter

For Christmas, I want a TouchBook with your screen. Including the chip to keep display working in suspend-to-ram mode. Pleeeease…

As long as battery time and display are good, don’t worry about the price too much..
