Everybody knows that the Good old CRT screen lasts forever and a day, however I am curious as to how long LCD screens last. I was recently in an electronics store and a salesman told me that the globe LCD TVs has a conservative burn time of around 10,000hours, the same for LCD projectors. After which time the globe can simply be replaced for a matter of a couple of hundred dollars. Conversely Plasma displays have a conservative lifetime of around 20,000hours at which time they are rendered useless and must be replaced. However there appeared to be two types of LCD TVs, ones very similar to computer monitors, and ones which appeared more like Rear projection TVs. The comment about a 10,000hour burn time was in reference to the rear projection style LCD TV. I was unable to finish my discussion about the computer monitor type and am curious as to how long we can expect the current generation of LCDs to last? Discuss.
