Hello.
After replacing the LCD on my phone, everything works, but scrolling makes the screen choppy almost imperceptible.
I don’t know if it's my Chinese screen, admit that it wasn’t delivered with an EMI shield.
The question is : a bad replacement of the display cable could be the cause of this malfunction?
If anyone knows it before testing it ...
Thanks for reply.
Is this a good question?

Screens usually don’t come with a back shield unless you buy the full assembly, there’s nothing unusual with that. No one can tell anything about the screen quality without testing, technicians are not wizards ;) Try your old screen if it’s still usable, otherwise you’ll need to have a replacement to rule out a possible faulty screen or confirm it’s a board issue..joys and pains of DIY approach unfortunately.

Hmm. With another approach:
What would be the symptom of misuse of EMI?

I can't really figure out what you mean by misuse of EMI, but the screen should be working fine with or without it if that's what you're asking.

Yes this my question. So another question, what is it purpose ?
by landaisbenj
I can't give you _THE_ right answer not being an Apple engineer, but I'd speculate it helps preventing electromagnetic interfearences from the board and at the same time improves LCM module strenght. Grounding purposes might be there too but it really goes beyond my knowledge.

Yes thanks !!! it's almost a great answer, and it's what i'm searching... I must determine if the plate has an impact on my screen (because i think i don't make a great fix). So I have to know the role of this plate, to know if I go back to try (knowledge better than test).
