Microlens arrays seem very interesting! I haven't seen any that are very high resolution... Is that because they kill the resolution of the display they're placed upon (as well as technical problems with very small microlenses)? So, we'd need extremely high resolution displays for microlens array displays to look reasonable by modern standards?
Perhaps actual phased array optics wouldn't have that issue?
For those just entering this thread, [1] is an example of a rudimentary microlens array display.
Looking glass factory is currently producing a display that puts microlenses on an 8K screen. The video of it looks quite good. It outputs 45 different angles, so the effective resolution is roughly 640p, right about at the bottom end of HD. Not the best but it's good enough for an lot and I'm sure the limit will improve over time. It's only horizontal parallax, but that's generally fine for a fixed screen.
