I have plasma laptop (Toshiba 3200). Made in 1988. It is on for 24/7 no screen saver, and it has no burn in or any anomalities.
You calculate the hours.
Plasma is developed way before LCD. Plasma was to be a future of screens, but that's not the way to go. You give me one reason why would ANY factory make screen that lasts "forever"?
Plasma screens are installed in US submarines since 1965, and they still work without ANY problems, 24/7.
Rember you are in the "game", and you HAVE, HAVE, HAVE, MUST , MUST , MUST buy new product at least every 5 years ot manufacturer goes out of bussines. You are not customer, you are CONSUMER.
If you do not consume you ar eseless.
Follow Ups:
The Compaq Portable III/386 or the Toshiba 3200 used a neon discharge display. That one had no phosphors and thus is not susceptible to burn-out. It also gave it the beautiful orange colour. I'm not sure of it, but it's possible that the new plasma RGB displays use phosphors and will burn out after some time.
I'm not a plasma expert but it seems to me that those old plasma displays on early laptops were replaced by LCD's on modern laptops. I see a trend here. Will it go this way with TV monitors, too?As for life expectancy, you are comparing old monochrome plasma screens that are normally run at low brightness levels compared to modern TV plasma displays that are run very bright over the entire visible color spectrum - not the same parameters at all.
