Did apple lock the screen programed to the cpu?

So I did some research about the touch id sensors and how apple locked them to the logic board. I did more research about the X, and I read somewhere that apple locked the face recognition from the screen to the logic board. Meaning, if I were to repair a broken iPhone X screen either, 1, the screen won't have functionality? or, 2, the face recognition won't function? can someone please answer this question... What i'm asking is if i replace a iPhone X screen, will the face recognition still work... bc I heard that they tided the restriction to the screen itself.
