How can I get faint white lines on my iPhone 15 screen fixed?

Hello! This morning as I woke up I noticed fsint white lines stretching up and down on my display. The touch is perfectly fine and has no issues. The lines seem to stay at the bottom and top of my screen, they do not seem to appear within the middle part of my phone screen. Last night I was playing music before I went to bed and I know there was nothing wrong with the screen then. But as I woke I noticed the lines, please help.
