Why Do Screens Glitch When You Turn Them On?

Sometimes screens glitch when you turn them on because they need time to wake up. It's like waking up from a deep sleep, your brain takes a second to get going, and your screen is the same! When the screen turns on, it needs to start showing pictures again, but sometimes it doesn't know exactly where to begin or how fast to go. That makes it flicker or glitch for a moment until everything gets sorted out.
