I saw 2 next-gen 3D TVs without glasses that use a new tech that changes everything — here’s how it works

Before we even get started here, I'll start with a disclaimer: I don't think 3D TVs are coming back to the home any time soon. However, after a couple of demos at CES of a new kind of seamless glasses-free 3D viewing on TVs – and this coming just a few weeks after seeing Avatar: Fire and Ash – I now think they should come back.

There were two notable examples at CES: one from Visual Semiconductor and one from TCL, which always has a cool range of next-gen display concepts at CES. It looks like both are based on the same tech as well: plenoptic displays, also known as light field displays.

I saw Visual Semiconductor's 'GF3D' display first, which it's really touting as a huge deal. "From black–and–white to color. From flat 2D to GF3D" is the slogan, so they're ...
