Any info on how it works?

There are multiple transparent lcd (or maybe led - idk) screens layered on top of each other. A different image is rendered on each layer to appear 3D. A single 8k video stream is sent to the display. Each 8k image is subdivided into multiple smaller images, one for each layer. So the entire image is 8k, not 8k per layer.

I know one of the cofounders, Alex, a bit. He’s a really earnest and excited person. He’s been working on 3D led tech for a long time. It’s been fun to see how’s his ideas have progressed. I have no reason to doubt their claims.

FYI, they are not the only company working on these types of displays. There is also an Irish company (I forgot their name) working with panels made by Panasonic. I think theirs are higher res than 8k.

Is this essentially the technology the 3DS used, only scaled up?

(I ask for clarification, not to diminish the achievement. If it is, and it works well, it's still a nice advancement. Nor am I saying it was invented for the 3DS.)

As I recall the 3DS used a lenticular lens: you see different images based on the angle to the display. Wikipedia has some more information: https://en.wikipedia.org/wiki/Lenticular_lens

What's the resolution of each layer and the resolution of the depth ?

That's impressive; and for me a bit reminiscent. I got my doctorate staring at macromolecular structures through various attempts at presenting them in 3d. One of the earliest I encountered was called a "Richard's Box"[0]. That setup was a set of clear plastic sheets on which were plotted 'slices' of electron density which were subsequently stacked-up with suitable sized spacers and you looked down through the stack with an lamp beneath. This approach sounds very similar, but with an active display in place of each sheet of plotter output.

It has an ordinary display and a lenticular lens on top of it.
