Why do LED lights flickers when seen on film/camera?
In: 2
A lot of LED arrays use something called multiplexing to light up more LEDs than it has the voltage to be able to. It does this by lighting only a few of them for a split second, then switch to lighting other LEDs, then right back to the first LEDs to power them again before they’ve completely dimmed.
To the naked eye, the lights aren’t turning on and off again, it’s continuous light, but a cameras shutter can pick it up.
