Apple has had its own display engineers since the '80s. Yes, they use several off the shelf components, but they're also known to create their own chips and oversee specialized manufacturing for particular models/challenges. Case in point was the 21" Apple CRT from the late '90s that featured a Sony Trinitron but also had custom Apple chips that auto calibrated as the display aged based on Apple's ColorSync technology. This looks like a similar collaboration.
You really think the largest company in the world (by market cap) doesn't actively collaborate with its source companies and do custom designs created by its internal engineers together with the supplier's engineers?
