  • PWM at 120hz.

    The frequency of 120 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

    • The OLED panel uses pulse width modulation (PWM) to control its brightness. This means that it flickers at a low frequency of 120 Hz across all the brightness levels we measured, which may be problematic for sensitive users.

      This means?!

      However, the display also works using high-frequency PWM dimming to compensate for the negative effects of PWM flickering. We measured a PWM dimming frequency of 3,846 Hz. How high it should nominally be is not stated in the phone's datasheet.

      Which is it?

      • I don't know either and it's annoying how they can sell mobile phones that may be harmful to our eyes. It's not only xiaomi either, it's almost all manufacturers.
