"the contrast ratio—the difference between lit and unlit picture elements—drops quickly under normal use, as much as 50 percent in four to five years. At that point, the television image appears noticeably washed-out. Manufacturers today claim 60 000 hours of use before the brightness falls by half (based on a few hundred hours of testing). Contrast, however, is more important than brightness. Recent tests by market research firm IDC, in Framingham, Mass., measured a 13 percent decline in the darkness of the black of a typical plasma television after four weeks of use; after five years of use, such a rapid decline could lead to blacks displaying as light grays."
