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.

There is a layer of glass, usually has an oleophobic coating on top to avoid getting too greasy from fingerprints, then comes the screen. You phones uses AMOLED technology, but there are other smartphones that use LCD. Both have a dense layer of tiny groups of colored light emitters that work together to create the images.
When you break the glass on top of the screen, since the screen is so close to the glass its probable that it damages it and the source of its energy, when that happens it can spread trought all of the screen. Some other times you get a thin line across the glass and it doesn’t affect the screen.
