Modern plasmas TVs are getting a bad rap

January 5th, 2007 · No Comments

Jim Palumbo, president of the US-based Display Coalition, says that it’s about time myths surrounding TVs that use the technology are put to bed. He maintains that stories about plasma screen burn and excessive power consumption are not relevant to current generation products.
Palumbo reveals that extensive torture tests organized by the PDC have had little impact on modern plasma displays. His organisation ran a series of phosphor aging tests on five large PDP screens, comprising eight hours of black and white checker boards, eight hours of colour bars and eight hours of a news channel running a ticker banner.
At the end of the tests, three of the five screens were clean of residual ghosting. One model had slight ghosting and the other seemed seriously burnt. Yet after three minutes of a white screen, it’s claimed all ghosting effects had been removed.
According to Palumbo, current PDP designs also draw less electricity than comparably sized CRT-based projection sets. The typical quoted life of a modern plasma screen is upwards of 60,000 hours.
Panasonic UK’s Nigel Thomas agrees. He maintains that there’s little difference in the actual power consumption of plasma compared to . While LCD uses a consistent amount of current because of their always on backlight, plasma has a variable power draw, depending on the amount of light or dark in the picture. “It works out about even,” he concludes.
