iPhone was in rain water for almost 6hours and the display is not working now.

hi, yesterday I had to use the rain in the rain for more than 6hours, after a little while using the phone in the rain, the display got a green straight line in its left side of the phone. But knowing that its bad for the phone, I had to use it continuously. and then the display got worst. The screen itself was doing a DJ by its own by screening the display white and black. yet it was useful so I had to use it in the rain. After 6-7 hours, went all black, but the phone was on, notifications were still coming but the screen was all black.

After 1 hour of not using the phone, I did plug the phone to the charger, it was still working but the display was not working(it was all black) .

And today its not working at all. Eventhough I plug it, it won't even give the charging vibrate. What might have happened to the phone and will I be able to fix the display?
