  • I think that’s PWM dimming vs DC dimming.

    PWM dimming turns pixels on and off to make them darker. So for 50% of the brightness, it’s off 50% of the time. Higher end panels flicker much faster which helps mitigate perceived flicker. I think 500hz and above is preferred.

    For DC dimming is just using voltage to control the darkness with no flickering involved.
