      That got me thinking: couldn’t that be solved by adding a layer in fron akin to a phosphor screen which “buffers” the light a bit thus bridging the switching which should reduce flickering?

        I think this would result in some pretty intense ghosting and other undesirable artifacts.

            That’s a good point, I don’t remember much ghosting on those. I guess it might depend on the phosphor used. If it was tuned to only fluoresce for that imperceptible off time and no longer it would probably work.

            I guess it’s a similar idea to quantum dots, but if those quantum dots fluoresced for just a bit longer.

      OLED TVs and desktop monitors don’t use pwm, though they do have very slight brightness dips every refresh.

      Afaik laptop and phone OLEDs do use (low frequency) pwm.

      Eventually, there will something like a 1000 Hz monitor. At some point, it will refresh too fast for the brain to register any difference.
