The quality of my PowerBook and 20" Cinema Display screens has degraded over time, they became noticeably yellowish and darker due to the wear of the backlight (I assume). Neither of those screens is LED-backlit. I'm wondering, how do the LED-backlit screens used in current Apple products degrade over time? Do they similarly become yellowish, give less light, …? How long does it take for the effect to become obvious, or what's the expected life time of these screens?
