This may not be so electronics related as to physics related.
Assuming I have a PoV display, which displays 8*X pixels.
How can I determine the minimum pwm frequency for the leds not to flicker ?
I can calculate the amount of time it takes the display to move 1 pixel, does the frequency of the pwm has to be (lets say) 100 times that time ?
Would that make every pixel appear as if it's flickering at 100Hz, which shouldn't be noticeable ?
Is my logic correct ?
