I'm very excited for hologram tech, from AR (Magic Leap, Hololens) to more "in-world" like voxon and looking glass[0]. It's great to see progress and competition in the space.

The display uses a dot lenticular film in front of a normal LCD display. The thick plastic and the lit up bezel is for giving 3D clues to fool the eye.
The pixels has to be shared among all possible viewing angles so this technology is mainly limited by display ppi and rendering power I think.
