iPhone display identified as an unknown part

The message says it all.

Either the original screen in your iPhone is acting up and is in need of replacement......or.......a third party shop installed a non-genuine screen in your iPhone.

If you have not ever had the screen replaced, then make an appointment at the Apple Store / Genius Bar or take the phone to an authorized Apple service shop to have the screen checked.

If a non-authorized shop installed a non-genuine screen in your iPhone, Apple will not help you in this case and you will need to take the phone back to the shop that did the work.
