Occasionally flickering and green screen

Hi all, I am new to iFixit! Thanks all for wonderful question and answers!

My iPhone 11 pro max was once bited by my kid and camera over filter damaged. It may induce some water damage.

Occaionally, the screen becomes normal (only top right corner problem). It seems tell me it is not the screen issue.

Yeah that's most likely a damaged screen, get it replaced. I'd recommend you buy a soft OLED panel as that's what's close to what the factory installed on the device. Hard OLED is cheaper but the OLED panel is thicker and it's more fragile. Then there's LCD panels which I do not recommend or offer in my shop. They require more current and the connector on the board wasn't designed to have that much current flow through it, so it ends up burning the display connector on the board in some cases.
