IMO this is heading in the wrong direction. It still involves backlighting the entire display area, and then selectively passing or blocking portions of that to create images. And now it also involves moving parts a la DLP (but different design). OLED and Sony's Crystal LED technology seem to me to be heading more in the right direction: solid state, no spatial light filtering, and high-fidelity intensity control. The first company that gets to the point of being able to "print" LEDs and related switches and circuits on a transparent panel is going to own the display market. Everything else will become like CRTs.
