Samsung F41 - PWM frequency

[Sousam20]

Does Samsung F41 uses PWM(pulse width modulation) to adjust brightness   and what is the frequency and on which brightness it applies??

[Anushka01]

no f41 doesn't supports pwm.

@ Anushka01 if it doesn't use PWM then it shouldn't strain eye except the blue light ? please inform me.

Ask Samsung, they only knows this. And I can guess that Samsung uses PWM to control brightness, even in M51.

@Shank_Sar why does in Samsung M11 blue light filter opacity/ opaqueness/ yellow tint cannot be increased manually over the default given by the company. it is stressful to eyes. Is there any option to do it????
