This makes no sense: 3D+2D TV: A 3D display that’s watchable without glasses, without ghosting | ExtremeTech.

You could wear a pair of glasses with the same polarized lens in both the left and right eyes and you’d see just one of the images.

Or you could wear a pair of LCD shutter glasses that turns the left and right eye lenses open simultaneously, so you see just one of the images.

And throw out the unused image (in other words, the 2D viewer sees only the left images).

Now you’ve got 3D and 2D viewers on one system, albeit, with half resolution one way or another for the 2D viewers. If they care. But that’s true of this 3D+2D TV system too, only its more complicated.

Which is why I don’t get this.
