Limit of human eye flicker perception? Any pointer to your brother's research/thesis? And +1 for suggesting alternatives to plain PWM in implementing the dimming while increasing the flicker frequency. |

Limit of human eye flicker perception? The capacitor across the LED needs to be several uF, thus has non-negligible cost and space. Also it multiplies the inrush current (for initially loading it) by a factor of about 3, exceeding the maximum rating of my output port. Outsourced PWM is not an option for same cost and space reason. Really my only option is to raise the flicker frequency. |

Limit of human eye flicker perception? Yes. My "I disregard purposefully moving one's head relative to the LEDs" should be re-stated as "LED does not move relative to head of observer". |

Limit of human eye flicker perception? I do have an incentive to lower the frequency: the PWM is in software, running simultaneously for 10 pins of some tiny CPU with individual dimming factor, and there are other stuff to do. From your answer and other sources I get that 60 Hz could be detectable in the dark, 1 kHz would not, but I'd like to reduce that interval. Surely that must have been studied. |
