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.

I have seen this inconsistency with notebookcheck. They list phones as having low PWM frequency when the manufacturer lists a much higher frequency.

But, yes there are many manufacturers who sell low PWM displays.
