Inside the MacBook Pro Retina-display

"Apple has managed to pack five times as many pixels into this panel compared to the older standard-display MacBook Pro notebooks, while still managing to shave a fraction of a millimeter off the thickness. To do this Apple has had to do away with the front glass on the panel — which has the advantage of cutting down glare — and used the aluminum case itself as the frame for the LCD panel.

This has essentially turned the notebook lid into a single, non-repairable unit. If you break the display, or if anything inside the panel dies — and both of these things happen more often than you’d like to believe — then the entire panel has to be replaced because the display is too fragile to be removed or handled outside of the frame.

Even the experts at iFixit, who are used to removing and handling fragile screens, managed to break the Retina display when attempting to remove it." via ZDNet
