iPhone screen is black, but I can still hear text messages, calls, etc.

I was wiping down my phone and then when I tried to charge it, a lightning connector warning showed up. I didn't think anything of it and continued charging which was dumb and careless of me. I tried force restarting it multiple times and it was still like that. I used another charger and charged my phone for a while and I turned it on. My screen wasn't black anymore, but there was a single pink line down the screen. I continued using my phone and then all of a sudden it glitched and turned off. I kept charging it using the undamaged charger and it keeps turning back on with that pink line and then shutting off and glitching. When the screen is black, there is a faint white light so I know when my phone is on the home screen and stuff. I also know where some apps are and clicked on those apps. The music from the apps played and everything it's just that my screen is messed up.
