Great picture; short lifespan. My company bought 52" plasmas for all the video conference rooms in January. ALL of them are burned.Akisa wrote:I was in Japan for two weeks this year and I didn't notice any. Next summer I am moving to Japan and I am thinking about getting one.

The lifespan was dreadfully short at only 2-4000 hours approx when they first appeared commercially a few years ago..
- Code: Select all
Trivia: The very first prototype for a plasma display monitor was invented in July 1964 at the University of Illinois by professors Donald Bitzer and Gene Slottow, and then graduate student Robert Willson. However, it was not until after the advent of digital and other technologies that successful plasma tvs became possible.
Today they tend to have at least 20,000 hours but are quoted as boasting 30,000 (CRT tvs are about 35,000) and up to 60,000 hours in some cases (but then these companies do tell alot of tall-tales)
(incedentally, 30000 hrs = 6 hours use, every single day of the year for about 13 1/2 years... and those 6 hours in Japan could easily be spent squished between salarymen and schoolgirls on a train chugging along through Saitama or Chiba... unless theres kids involved the TVs will last a decent amount of time IMO)
As for ReGassing your plasma - as far as i know its not possible - and if it is its reputed to be expensive..
As for the burning - some of the more recent models include features to prevent this from happening - eg one of the Sonys I had been selling last year in my parttime jobThe technology behind a gas plasma is similar to that of a CRT display in that the image consists of a lit-phosphor coating. A CRT uses an electron gun to ignite the phosphor, while a plasma uses gas. The phosphors are red, green, or blue pixel-sized spots. The downside is that the phosphor coating is much thinner on a plasma than it is on a direct-view CRT display, so phosphor wear occurs much faster. However, the KZ-42TS1 has both a picture inverter and an orbiter mode to protect it from uneven phosphor wear. The inverter mode imperceptibly reverses white to black and black to white, thus oppositely wearing the image to help reverse the effects of uneven panel wear. The orbiter mode also helps prevent noticeably uneven wear by moving the picture around in a circle. The picture only moves a few pixels, but it's enough to keep fixed horizontal and/or vertical images from burning into the phosphors in one spot. The orbiter's revolution time is adjustable from 10 seconds to five minutes.

All great info! Thanks!.. Thus far, I'm still satisfied with my CRT, but I'm curious about new technology..emperor wrote:.. but I had the money to blow and a big room to put it on:
Id probably opt for a plasma instead (specifically a Pioneer)
or maybe a top of the line OHP
