>ESA and NASA space missions have carried this trailblazing ZEISS technology on board for many years. It is also well established in the semiconductor and medical technology sectors.

Huh. Seems like it should be fairly easy to find info on then... though some googling around makes me think they might just be referring to their more general diffraction gratings and whatnot.

This looks really cool.

Could you put a polarizer on this and have that filler out the other side of the display, so a smart window is one way visible? That could make smart glasses and headsets much better.

I doubt you'd even need to. The fact that it's not a uniform grey blob means they're already controlling how the light leaves the device. I suspect it's already directional.
