60% ? Impressive, I wonder how they achieve that. If they start from white light, isn't color filtering supposed to eat its share anyway, even if it's done sequentially ?

I mean, assuming that the Red, Green, Blue was a partition of the optical spectrum with equivalent energy to each color...
-When displaying red, green and blue have to be filtered out, so there go two thirds of the energy.
-When displaying green, red and blue have to be filtered out
-When displaying blue, red and green have to be filtered out

Or isn't it so ?

EDIT : Okay, according to this https://secure.wikimedia.org/wikipedia/en/wiki/Time-multiplexed_opti... , they don't start from white light, but have a light source that can intermittently emit red, green, and blue light instead.

How can such a source work ?
