Sulla longevità del plasma
http://www.plasmatvbuyingguide.com/plasmatv/plasmatv-lifespan.html
"For consumer use these numbers should be comforting. Plasma Displays are
now about equivalent in longevity to LCDs, which typically state 60,000
hours. Consider that these figures are a great amount more than old CRTs,
which regularly post life span to half brightness at 25,000 hours. Let's put
these hours in perspective. The average U.S. household watches 4 to 6 hours
of television per day. Staggering. Taking a mean time manufacturer stated
longevity of 50,000 hours of usage, times our average 5 hours per day,
calculates to over 27 years of usage. "
Nell'ultima parte viene spiegato il metodo scientifico usato per stimare la vita
del pannello. Si tiene lo schermo acceso con un bianco al 100% di luminosità
per il tempo necessario a raggiungere il dimezzamento della luminosità, cosa che richiede mesi. Dopodiché si fa una stima di quanto
tempo tempo è necessario al dimezzamento della luminosità in condizioni d'uso normali.
Considerato l'utilizzo tradizionale (nessuno lo userà per illuminare la
stanza
"At 15,000 to 20,000 hours the monitor should measure around 80% brightness,
or to state is technically, 80% of the original phosphors (gases) are being
ignited."
Quindi usato per 5ore al giorno dopo *11* anni un plasma di oggi conserva
l'80% di luminosità! :yeah: Quindi ancora perfettamente fruibile. Considerato che
tra 5 anni ci saranno i motivi per passare a tecnologie nuove o prendere
plasma allo stato dell'arte, il luogo comune della vita corta dei plasma
resta solo per i detrattori un po' ignoranti del plasma.

Service life EXCELLENT: Panel service life of approximately 60,000
hours.(*1)
Plasma life span: The life span of plasma TVs is another area that's
improved dramatically over the last few generations of the technology.
Partly in response to claims made by LCD TV makers, plasma manufacturers are
now claiming their panels last an extremely long time. Most plasma makers
today claim that their 2005 models have a life span of 60,000 hours before
the panel fades to half-brightness. According to a 2000 Nielsen study, the
average TV in a household is on for 7 hours, 40 minutes per day. Even if the
real figure is closer to 30,000 hours, that works out to more than 10.5
years before the plasma reaches half-brightness--about what you'd expect
from a direct-view CRT.
In short, plasma is a perfectly durable technology that's still a much
better value than LCD in larger screen sizes.
