I can imagine a display where the "white" part was phosphorecent, or fluorescent like the white surface of a fluorescent light bulb, opaque to visible light, but energized from below, and then self-illuminated with a perfectly even glow.

Hmm...should I have spoken to a patent lawyer before posting this....?
Ha! That's a very cool idea. The backlight would probably only have to be on for a brief time while the screen is flashing to a new state, thus dropping the power required even more.

I suppose they could also impregnate the white balls with tritium to always make them glow (for about 10 years, anyway), like on watch faces, but I suspect people wouldn't be too happy with radioactive devices.
