These bright green lines on the iPhone screen can be caused for several causes. Unfortunately, the most common, indicates a damaged LCD screen following a mechanical shock. This can be due to the phone's fall, liquid exposure or blows. The problem can be remedied in an Apple Authorized Service, where the iPhone screen will most likely be replaced.
A malfunction of the internal components of the iPhone, such as the motherboard or display chip, can also cause green lines on the screen. And a connector with an imperfect contact at the motherboard or affected by liquids, can cause display problems.
In rare cases, these green lines on the iPhone screen may occur due to exposure to strong electromagnetic interference or overheating the device. Most of the time, in these situations the screen returns to normal after a while.

If the above methods do not work, it means it is a more serious problem and you have to contact a Apple authorized service for assistance. We do not recommend that you call for clandestin service or not authorized Apple.
I had this green spot on the screen and in the end I arrived with iPhone in service. Big costs for changing display and touch.
It was done to me after I sat on it. green lines appeared vertically.
To me the white screen was made then total green after making it alone the last update. January 2025. Now it costs me a new display because Apple has bugs in the last software. I am good to pay for nothing. Only software update, no shocks did not stand with the bottom on the phone, not put to water, nothing. I get angry when you see the same instructions for reset, but you can now see a solution from Apple for these mistakes.
Health,
If your iPhone is still under warranty I can go with it to an Apple Authorized Service. There he will diagnose him and he will be determined if the repair is covered by the guarantee.
Personally, I recommend Depanero. It is Apple Authorized Service and we have had good experiences for the devices we have sent for service to them (iPad, MacBook).
