I'm having some difficulty locating any info on the useful life span of the current models of flat panel LCD and Plasma TV's. Most all comments I've seen make some reference to warranty length, but that's not really pertinent to my interests.

Essentially, is there a substantial difference between these two technologies in how long they'll last (useful hours) before they begin to substantially deteriorate in picture quality or function? If you don't know, do you have any suggestions on how to obtain that info?

Tanks!!

Thanks for the reply. While I have no evidence to support my opinion, I'm still inclined to believe there's a difference between LCD and Plasma life spans.

You might get some answers by going to some home theater forums.

It really depends on the way it's all done.

A rear-projection system requires that a bulb be used to project the image on a large screen. Incandescent bulbs have an average life-span of 3,000 hours. Newer TVs now use LED bulbs that give better images AND have life-spans of almost 100,000 hours.
