Comment:

i was in a store recently and saw a discount on a 22" floor-model LCD screen. It looked like a deal, and i was tempted to buy, but those thing are on all day long. if this screen has been on for three months, is it almost burned out? what is the life span of an LCD screen?

The average life expecancy is 50,000 to 60,000 hrs of use. I don't think it matters if it is continous or intermittent. 8760 hrs in a year.

You can get that for $289.99 at newegg, so I don't think it's that much of a discount. I'd rather spend the extra $40 and get a new LCD monitor.

Below is a link to Newegg.com for 22" LCD displays for comparison purposes.
What about warranty on the monitor? If not full warranty I would be cautious. Look for dead pixels and marked up screen. If it isn't running make them run it for you. Where do you live? I actually prefer to buy LCD displays locally due to pixel exchange policies online. If I don't like it from Bestbuy it goes back. Online isn't that easy.

Actually the MTBF for laptop light bulbs varies from 10,000 hours to 60,000 hours. When on 24/7 it will be roughly 1-6 years.

Below is a link to that display. The specs state the life expectancy is 40,000 hours.

For 40,000 hours it will last roughly 4.5 years when on 24/7. It could be less or even more as no two LCDs of the same type are built alike. (Nothing are built alike anyway). This is why we use MTBF as an accepted guideline.

At any rate the 3 months time period is not a big deal. I doubt they ran the stuff 24/7 anyway, electricity you know.

Indeed :-) I reckon the MTBF of anything meant the time something is expected to die whether or not you use it. It's like the car oil change recommendation of 3,000 miles or 3 months whichever come first.

No, that is the average life expectancy under use. TVs have had this type of rating for years. The time your set will last is determined by how many hours a day on average you have in on. The LCD display is the same thing. Harddrives are the same thing. 100,000 or 200,000 hours is the average time they should last. Of course electrical surges and things like that aren't taken into account.
