So we have some old couple ipads/ iphones that my dad wish to give to my cousin coz he badly wants one. So my dad really wanted to give it as if like its brand new so my dad would want to have the screens replaced since theres some scratches existing already +'the oleophobic coating has already worn off. So here's my question.. What does LCD do? i mean, when i asked the repair store, they say LCD is included in the repair even if i just want to replace the glass. Does that have anything to do with the quality of the screen display? If i swapped the original screen to the one in the repair, will it lessen the screen quality and have obvious pixels on it? will i retain the retina display? or will the performance be bad? Would be nice if anyone of you would share experiences about the replacement of their screens since theres no authorized/ legit iphone repair. Ofcourse we cant go with the apple care coz thats just too expensive, so im just trying to make sure what we're dealing with. Other than that, i also want to know other things that we may need to check for the replacement. Thank you! the display and the performance is really important since it will be a gift.
