In previous colour LCD screens, the colours have been provided by a fine colour filter - giving RGB dots or lines. The Pixel-Qi screen doesn't work like that. There are
no colour filters at all. All the colour is provided by passing the backlight through a clever diffractiongrating/lens system to give diagonal stripes of colour. If there's no backlight, there's no colour.
It really is clever. But it does mean that without the backlight you only have B&W.

Though I wonder what's so bad about blurred out pictures in color. We all are happy to have a reflective power effective screen! Even if the colors aren't showing as well, I think it's still better to have them available without backlight, then not having them at all.
