They use a single standard display with advanced optics to send light from columns of pixels in different horizontal directions. You can see here https://docs.lookingglassfactory.com/keyconcepts/quilts https://docs.lookingglassfactory.com/keyconcepts/quilts the format it uses to display still images. The 8K version is 5 by 9 for 45 separate angles, giving a 3D resolution of 864x864x45(horizontal). As somebody else said, it's not really a voxel because the 3d effect is technically a trick and doesn't work on other axes. If you think 864p seems low for a 32" display, that's because it is - I've seen these in person and they have terrible pixel density. They're still very cool, though. 3D without glasses or a headset is impressive.
