I understand why we see them flicker in videos, but why do LEDs flicker at all when they’re powered with DC?

Light up all lights and it use “lot” of power which usually end up creating heat somewhere and that can be hard to manage at some point. (Hard and/or costly)
Our eyes (or brain?) is kinda slow at reacting to light. So we found out that we can cycle trough leds fast enough to make them look like all of them are light up.
On a parallel subject, I don’t know if this is our eyes/brain or leds themselves, but if you start playing with the on/off ratio time you see them like they are dimmed. This is called PWM (Pulse Width Modulation)
