This is a horrible misuse of the term "light-field" for a display.<p>An actual light-field display would have, for every pixel, maybe 16 sub-pixels, each only visible from a certain vantage point. They represent the rays that travel through each point in space.<p>This is something that could bring true glass-less 3-D, and would be an ideal VR holographic display if they could make a 16K display that could fit in a headset. You wouldn't even need lenses to focus - just stick the display right up to your face.
