Comparing the Pixel Qi screen to others

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.
