"DuPont's been dabbling in OLED advancement for years now, and while the world waits for the introduction of market-ready big-screen OLED HDTVs, engineers at the miracle-working company are toiling away to make sure those very sets last quite some time. For anyone following the OLED TV scene, you'll know that luminance longevity has been a nagging issue, but if new developments pan out, stamina will be the least of our worries. In fact, the firm has crafted a green light-emitting material that can purportedly push onward for over a hundred years... continuously. Furthermore, the same scientists have engineered a new blue light-emitting material with a luminance half-life of 38,000 hours along with a red light-emitting material with a life of 62,000 hours. Unfortunately for the laypeople out there, we can't imagine this stuff being even marginally affordable -- but hey, it's great news for the sybarites!"^^<http://www.w3.org/2001/XMLSchema#string>
