I cracked my screen and thought for sure something inside of my iPhone XR was broke, but the tech came to my apartment and 30 minutes later, my phone was back to new.
It got me wondering, how does the screen really work? Is the picture in the glass itself and that’s why it can just be replaced and back to normal? Is there something behind that glass that had to be replaced too? Where the hell does the picture even come from.
Sorry if I’m asking too many questions but I’m so intrigued after my screen was literally cracked and there were black spots and green and black lines all over it, and just by replacing the glass it’s back to normal.

The screen itself is just millions of tiny lights that can show either Red, Green, or Blue. [Here’s a video to demonstrate that](https://m.youtube.com/watch?v=MIiI7ZlHtTg)
A cable connects the screen to the rest of the phone. The rest of the phone tells the screen which of those tiny little lights to turn on, which colors, and how bright each light needs to be.
If the screen cracked, it’s probably just the lights that are damaged, or the structure holding all the lights in exactly their right spot. But the phone is still sending messages. So if you attach a new screen with un-damaged lights, everything starts working again.
