Backs up claims of high replacement cost
iFixit has conducted a narrower teardown of the new MacBook Pro, this time concentrating solely on the computer's Retina display. The repair firm notes that the LCD is "essentially the entire display assembly," in that instead of combining with a back case and a sheet of glass in front, the LCD exists on its own, with the Pro's case serving as a frame. The reduced glare of the notebook is attributed to removing front glass from the equation.
The display is nevertheless said to be just over 7mm at its thickest point, and a little over 3mm at the thinnest, making it less than a millimeter thinner than non-Retina Pros. A strip of 48 LEDs at the bottom is used for backlighting. Apple's concern with efficiency extends to cables, which are routed through the display's hinges, meaning that both parts must be replaced simultaneously if one or the other breaks.
iFixit complains that because of the display's tight integration, it's impossible to replace just the LCD. The company in fact notes that the very process of opening the display means that if anything else breaks, the whole assembly must be swapped out. Any kind of screen failure, therefore, may be extremely expensive.
