And even there, 12 Hz is probably pushing it in terms of flicker.
For a 1 meter diameter and height cylinder at 60Hz voxel refresh and say 1mm resolution at the edge one would need the plane rotating at obviously 3600 rpm, and edge pixels switching at about 380KHz. Since rgb is nice to have that's 10 gigabit for a somewhat coarse display. Nothing impossible, but not a DIY territory yet.
I think one'd want the LEDs either on the receding or the advancing halves of the plate, depending on which is best for the cooling -- not all on the same side or on both -- that would be just a waste.
Or even just on one half of the plate, the other being just a countermass. This way cuts the bandwidth in two.
The edge of such a display would also be moving at several hundred miles per hour, which creates it own whole set of problems.
You would still need a bare minimum of 1-2 kHz, and a lot of screens, and balancing every layer would be super difficult, but I don’t think anything about it is fundamentally impossible with current technology.
Are phone screens (minus the phone etc) transparent?
