Actually the display I'm talking about wasn't a 3d display it was a wearable holographic HUD I saw at a DARPA demo day. The use-case for these kinds of displays is pretty much to ensure a graphic on the display stays in focus no matter where your eyes focus, or where they are relative to the display by producing a hologram of the display.
It's subtly different from similar see-through HUDs because you don't have to keep changing your focus back and forth to the HUD.
The DARPA guy I was talking to wasn't working on the display but on some other bits of the HUD and didn't know all the details about how it worked sadly. Looking for it later I think it was a holographic waveguide technology.
