The 11" MacBook Air used an LCD screen, not OLED. It may have an LED backlight, but that’s not the same thing.
Not sure why the pulse width is so large on the screens you had trouble with. LEDs can pulse millions of times per second, far beyond what human eyes can perceive. 240Hz, on the other hand, is well within the range of human perception, so they’re lucky if that didn’t also cause epileptic seizures.
Yes, the LCD on the MacBook is where I learned of pwm dimming to start with. It’s a solved issue for most LCD manufacturers.
Most OLED panels in the consumer market pulse at 240Hz. I can’t see the flicker, but text is wobbly on the screen for me and I get headaches after a bit. Turn the brightness to 100 … no more wobble, no more headache, and no more pwm.
