My phone has gone purple?

I've had my iPhone 5s brand new for a few years ( dropped it very few times) i woke up this morning and went on my phone and it was fine but I've just gone on it now and it has purple lines down the screen and i can't see anything is it broken? I've just turned it completely off and I turned it back on but nothings happening. Thanks for any helpful answers

I don't mean that I want it to disappear, I just want to know if there's an app that will hide it or sort of make it less noticeable. Before you tell me to go replace it, I already tried but Apple wants to charge me $270
