Appears similar to the tech in the Nintendo 3DS: lenses over the screen so each eye sees a different picture. See https://en.wikipedia.org/wiki/Autostereoscopy

Why does it appear similar to that tech other than you get a 3d image? As far as I can tell there's no info on the display other than it uses "Light field technology" which would make it different than the parallax barrier display on the 3DS.

  The term light field technology is broad enough to cover lenticular arrays in displays. The 3DS had the major limitation that it only rendered two views. If you increase the resolution to be able to display more views for more viewing directions within a wider cone, you already have a light field display - simply because all these views combined form a sampled light field representation by definition. This is exactly the same as glassless 3d displays for multiple viewers of decades past. But advances in display pixel density and computing power apparently make the resulting illusion much more convincing these days.

    Isn't it clear glass and not a layer over a traditional display like the 3DS? Glasses would either actively time slice with shutters, or spectrum slice with passive filters on the lens and of course you need the glasses. How could any of those technologies be what is used here? E: Looking again, perhaps it could be some layer over a traditional screen. You see through some of the broadcasts but that could just be the digital far plane that shows through.

      I'm not sure I'm following. If this is based on a flat panel display, there must be a lens array in front of it. There is no other way to achieve this effect without requiring the users to wear glasses. The lens array can be covered by a protective flat glass pane without issue.
