Another highlight in the WWWDC2012 is the announce of the MacBook Pro with Retina Display. iFixit recently posted their teardown the display. It's an engineer miracle!
● The display hinges have cables routed through them. You'll have to replace both the cable and hinge at the same time.
● Phillips screws holding the Retina display in place.
● Despite being super careful, they broke the display
● There were two thin strips of adhesive underneath the glass holding it in place
● The fused glass and LCD combo is about 1.5 mm thick, and that includes the metal mounting plates.
● The camera cable is routed along the outside edge of the display assembly, making replacement very difficult and costly.
● Underneath the top layer we find a series of films and sheets that manipulate light before sending it to the user's eye.
● A strip of 48 LEDs at the bottom of the display assembly provides all the light your Retina display needs.
What we can tell you is that if anything in the display assembly breaks, you'll need to replace the whole thing. It will be more expensive than just replacing the LCD inside a regular MacBook Pro, but it will also make the choice (of whether to replace just LCD or entire display assembly) very easy.
Take a look at a few photos below.
