Hi,
perhaps this helps:
the iPhone XR is the phone I can stand the best - no eyestrain, no headache.
So I was happy to read that the iPhone 11 uses the same display . I bought one and it was a pain I can hardly use it so I gave it away to my wife.
Some research showed that unfortunately Apple uses 3 different vendors for these devices:
Toshiba: C11 orF7C
LG: DTP or C3F
Sharp: DKH
Unfortuntely again I could not find a way to identify the display without using special hardware.
Perhaps others experienced the same.
I Use iOS 16.7.1
