Parallax Hardware Layering

Curious if parallax occlusion can be built into monitors directly as thin layer displays for 3D without requiring glasses or external sources.

It is an interesting question....

There is no practical way to accomplish this with current technology. If you just make a display with two layers, it would not work because both eyes would see both layers. 3D requires glasses because, in addition to the display creating two offset images, you need a way to prevent each eye from seeing the opposing image.

 

The only way to do this without glasses would be to create two layers that can be seen at certain angles, but become invisible at a slightly different angle, so each eye would only see one layer. And this would only work at some specific head position, moving even a few centimeters would lose the effect. Maybe it would be feasible if we had multi-layer panels that could have very tight viewing angles that become invisible outside those angles, and in addition can change the direction of the angles in real time, combined with eye tracking technology. It would be very complicated.

Also I think MIMO technology could allow for viewer detection by infrared positioning sensors to direct lightrays at approximately decent angles to each viewer.
