so, if its that clear that my finger oils have stripped away the AR coating from the screen (what is AR, btw?) what do I do to fix this... if I am not torying to remove a smudge and am instead dealing with something missing, as you said, what can be done to remove the appearance of the spots? its really really really annoying!
You cant fix it, its the display assy. You either live with it or have the display removed and replaced. However it will occur again immediately if you are one of those rare people that excretes very acidic skin oils.
There is nothing to REMOVE, what your looking at is what is MISSING. Its been removed already
I used to fix computers for years, and have years of experience in an optical shop messing around with AR coatings. skin acids and oils strip the antiglare crystaline coatings.
whats left is the glass substrate and screen reflecting back normally as bare glass does.
If you look closely at your picture, you can see its a mirror image of your keys, and negative image of your trackpad.
Ive seen this before many times. 9 times out of 10 its someone that has very acidic skin excretions left on the palm rests and keys that transfers to the screen, which THEN strips off the AR coating.
You can also EASILY see there are more oils / spots near the top edge of either side of the trackpad where your palm rest and excrete the oils and acids.
See that purplish tint on your display?? Thats the AR (some call it anti-glare) coating.
You can stop this by using a very very thin piece of felt (VERY THIN) paper or plastic between the screen and keyboard.
