"Perceiveved brightness"?
And perceiveved brightness is equal to the peak of the PWM wave?
That image from courtesy Daylight Computer Company is consuming too much of my attention.
- mrob 1y agoI've seen this repeated many times but never seem any evidence for it. At typical PWM frequencies the perceived brightness is just the average brightness of the wave. I believe this myth arose from people driving low-brightness indicator LEDs using PWM for increased efficiency when using simple current-limiting resistor circuits. People saw the energy savings from less waste heat in the resistor and somehow confused it with something happening in the eye.
