The second question that I get from friends or family when discussing plasma TVs is, "Plasmas don't last as long right, they burn out faster (than other television technologies)? The short answer to this question among top tier brands is, "No, plasma is the equivalent of LCD/LED in lifespan as a technology, though there is variation among brands and models".
FYI: The first question is, invariably, "Which is better, LCD or Plasma (TV technology). See our article: Plasma TV vs. LCD.
Plasma TV life span expectancy has long been a hot topic and rightly so. Most early plasma monitor models from 1999 and early 2000 have already been delivered to the electronics graveyard. Manufacturers were doing well to deliver a plasma product that fired up. An early adoptor could purchase a plasma TV that was 6" in depth, was hot enough to fry an egg on, and had fans that sounded like it was going to take off and fly through the roof - all for a modest $10,000.
However, improvements in the longevity of plasma TVs and displays have been rapidly effective. The green phosphors are claimed by some manufacturers as the reason behind the incredible increase. Lower power usage and motion adaptive anti burn-in technology are also contributors.
In fact, many plasma manufacturers boast a life span of 100,000 hours to half life! This is a longer life than a tube based television. The specification is somewhat suspect since the process of determining longevity of the product is based on deductive mathematical calculation of phosphor dissipation, and does not take into account the electronic components and the myriad of problems that can occur. Panasonic was the first to claim the 60,000 hour life span, up from a previous 30,000 just a year prior and now Samsung, LG and Panasonic claim 100,000 hours to half life.
So how long will a plasma last? The long and short of it is that it depends upon your daily hourly usage as well as how you use the monitor. 4 to 55 years is my new short answer.
One practical example I will cite here is the Panasonic Tau units being used by video rental company, In Motion Pictures at major airports around the country. Most of the earlier Tau models have now been replaced by a newer model, but these plasma displays were used for 5 years and were the first generation of plasma displays to go a considerable distance. In Motion displays images on them from 6AM until 10PM daily (16 hours). By my estimates, these early plasma displays by Panasonic were in use by In Motion for around 30,000 hours or more. They never fail to catch my eye as I pass by in one airport or another to see if they are still in use. If they have lost some of their brightness level its hard to tell. This use equates to 18 years for a home owner that watches 3 hours television per day. So a 100,000 hour lifespan for a plasma TV will mean triple that to 54 years at 3 hours per day.
