> make moving pictures appear seamless

True enough.

NTSC is 30fps, while PAL is 25fps.

The overwhelming majority of people were happy enough to spend, what, billions on screens and displays capable of displaying motion picture in those formats.

That there is evidence that most(?) people are able to sense high frequency PWM signals doesn’t make the claim that 15 to 20 frames per second is sufficient to make moving pictures appear seamless.

I’ve walked in to rooms where the LED lighting looks fine to me, and the person I was with has stopped, said “nope” and turned around and walked out, because to them the PWM driver LED lighting makes the room look illuminated by night club strobe lighting.

That doesn’t invalidate my experience.
