What is flicker?

Flicker is when something looks like it’s blinking on and off, even though it’s not really stopping.

Imagine you're sitting in a room with a light bulb that's not working right, sometimes it's bright, and sometimes it's dim. That’s flicker. It's like when your favorite toy starts to glow strongly, then gets weak, then strong again, over and over, even though the toy is still on.

Think of a light bulb as a little dancer. If the music playing for her changes speed or volume suddenly, she might move faster or slower, or even stop for a second, that’s flicker. In real life, flicker happens when the electricity coming to your lights or screen doesn’t flow smoothly.

It's like watching a movie on a screen that sometimes gets brighter and then dimmer, it can make you feel dizzy or tired if it happens a lot. Some people even get headaches from it, just like how some kids get headaches after playing too long in the sun.
