Do you have any sources for that?
Frankly it sounds like BS to me.
Solid objects (like ink-printed paper) reflect light and therfore have subtractive coloring. The CMY inks don't absorb enough light to make black well, or at least they're hard to combine that way.
Lights, like these OLEDs, are additive color. I can't imagine them not being able to make white.
I've played with colored light bulbs in a darkroom before and you can make it perfectly white pretty easily. Mixing crayons to make black doesn't seem to work, though. Same concepts as far as I can see.
These things sound interesting. There is no constant backlight, so presumably you save a lot of enery buy using just enough to make the right color and brightness instead of powering a constant white and dimming it with LCDs in front.
