I thought it is the other way around. It's the LCD that degrade over time. My understanding is now that issue has been solved by using led. I can remember all the detail but my memory says I have read that somewhere, hehe. However, not all lcd panel has that new method.
So I'm researching HDTV's (again) and I've got a fundamental question. Do LCD TVs picture quality degrade over time?
Most of my original TV research was done 5-6 years ago, and I know a lot has changed since then. I'm getting re-familiarized and I think I may be hanging on to an old notion. Originally I dismissed Plasma TV's because their picture quality degrades over time. The "lifespan" of the TV is typically about 60,000 hrs as I recall, and represents the half life of the color intensity (i.e. picture degradation is logarithmic and after 60,000 hrs the color intensity will be half of what it originally was). I didn't like the idea that the picture will never look as good as the day I bought it.
However, with all that talk about picture quality degradation, and all the comparisons being made, I suppose I may have incorrectly assumed that LCD TVs will never lose their picture quality. Now, thinking back on that, the concept seems naive. Something's gotta give eventually, right?
So, realistically, by the time the plasma reaches it's half life, is the picture on the LCD much worse than it was originally?
I'm currently revisiting plasma's, because I value picture quality, black levels & shadow detail, and I don't entirely trust the Vizio brand, which seems to be the only decent LED TV w/local dimming right now. Has the lifespan of plasmas increased significantly? Is the "burn in issue" pretty much resolved at this point? (orbiting pixels was a new concept when I first researched the topic)
