Screen Flicker (PWM) question



Hi

My eyes are kind of damaged and I need to know if the Nexus 6P phone screen uses PWM for backlight dimming. Majority of people never notice it but I'd say 5% of people have issues caused by it (headache, migraines, seizures, etc.) Kind of like the CRT flicker but in modern LED backlit devices.

To test use a high end camera/DSLR with adjustable shutter speed and look for black lines on the phone screen when adjusting the camera's shutter speed.

Info about PWM: tftcentral.co.uk/articles/pulse_width_modulation.htm

Thanks
