My phone is working but it has a blank screen!

Hi,

So i kinda washed my phone and after that i immediately dried it but after a few seconds the left side of the screen got darker the right side and after 3 seconds the screen started flicking and it got black i turned the phone off and placed it in rice for 38 hours but still the screen is black but the buttons are responding and i can feel vibration on my screen when i touch it but the screen is all black the phone charges good. I tried flashing new firmware but it doesn't work. I kept the phone on for a day but it also didn't work.

Hope i will get the answer.
