What are the main differences between Plasma TVs and LCD TVs?
I'm looking to purchase a new television. I've talked to a couple people about the main differences between plasma and lcd. I still don't have an answer as to why LCDs are so much more expensive. Can anyone give me the most important differences between the two technologies?

Answer by QQQ
LCD's are expensive mostly because they're much more expensive and difficult to manufacture than Plasma screens.
Both LCD and Plasma offer almost-equal picture quality. It also depends on a few circumstances, like the build quality of the TV itself, and room lighting conditions.
In larger sizes, plasma will have the advantage. LCD has the edge in smaller sizes. In viewing quality, plasma has an advantage when displaying blacks, but the nature of plasma makes it better for viewing in environments where you can control the lighting. LCDs offer anti-glare and will produce a better visual quality in brighter rooms. The latest generation of LCDs have all but removed the "viewing angle" issue. However, some less-known and cheaper brands of LCD displays will not have as good of a viewing angle. For a long time LCDs were the winner when it came to resolution (pixels per screen size). Plasma, however, is closing the gap in the 50-inch display range.

There are several differences, but it all depends on your viewing situation.
Concerning the room the TV will go in:
If you have a TV in that room now and you have a noticeble problem with glare, plasma is not the TV for you. Plasmas typically have glossier, more reflective screens that on a large scale will eventually become irritating.
Concerning the type of programming you watch:
If you watch sports, action movies play video games, or anything with a lot of motion, plasma wins here. What you need to look for is a TV with a high refresh rate. This allows the television to keep up with the action that your video source is sending to it, reducing motion blur and “ghosting” Currently, the LCDs that are in stores in the affordable price ranges have 2 different refresh rates: 60 hz and 120 hz. 120 hz is typically on the expensive side as it is a relatively new technology. Plasmas (specifically Panasonic) have refresh rates of 480 hz (4x as fast as the high end LCD), thus eliminating problems with blurring or ghosting.
Also, plasmas have much better black levels than LCDs do and usually higher contrast ratios, making richer colors and blacks that actually look black instead of washed out.
If cost is an issue:
Plasma wins again. Take Sony’s top of the line TV, the XBR series. For a 46″ Sony KDL46XBR4, a TV with 120 hz and an 18,000:1 contrast ratio, you can expect to spend at least $ 2100. Compare that to the Panasonic TH46PZ85U, a 46″ plasma with 480 hz and a 30,000:1 contrast ratio whcih typically sells for $ 1799.
Myths about plasmas that are false:
Plasmas only last 5-7 years. FALSE, they have the same life expectancy of an LCD.
You can get screen burn in easily: True and False. Entry level plasmas…yes. Check to make sure that the plasma you are looking at has a pixel shifting technology. This moves pixels around the scren every so often to ensure the same pixel is never constantly in the same spot…thus eliminating screen burn in.
Oh and if anyone tells you that LCDs can’t get screen burn in, they are flat out lying or are misinformed.
All in all, both plasma and LCD are great technologies that have advantages and disadvantages. my advice: go stand in front of the TV that you are looking at. Compare picture qualities and decide on something that YOU think looks good. Ultimately, you are going to be the owners of that TV, not the guy selling it to you.
