You know you want to buy a flat-screen TV but you don't know if a plasma TV or an LCD TV would be your best choice.

This article explains the differences between plasma versus LCD TVs, then shows you how to get the best price for a plasma or LCD TV.

Plasma TV

A plasma TV screen consists of millions of multi-colored gas-filled cells. When electricity passes through the cells they light up and produce a picture.Plasma TV screens have a much higher resolution than tube TV screens. In fact, the picture is so clear it's almost like watching a scene through a window.
Screen sizes range from 42" to 65" wide and are 3" to 4" thick.

LCD TV

LCD (light crystal display) TV screens are made up of a thin layer of liquid crystals sandwiched between two glass plates. When an electricity is sent through the crystals an array of tiny multi-colored pixels light up to create a picture. LCD TV screens are thinner and lighter than plasma screens. They are the most screens for computers, and are quickly gaining popularity as TV screens. LCD TV screens are anywhere from 1/4" to 4" thick and 2" to 65" wide.

Plasma vs. LCD Features

- Picture Quality

When it comes to which type of TV screen is sharper and shows more detail, plasma TVs have a slight edge over LCD TVs, though LCD TVs are catching up.Plasma TVs are also slightly better when it comes to viewing angle – how far you can sit to one side of a TV screen before picture quality is affected.

- Screen Life

Screen life is the number of hours a TV provides before the picture begins to fade. Plasma TVs have a screen life of about 30,000 to 60,00 hours, depending on the make and model, while LCD TV's have a screen life of 60,000 hours or more.Plasma TVs are also subject to "burn in." This occurs when a TV displays a still image long enough for a ghost of that image to be burned into the screen. LCD TVs do not have this problem.

- HD TV

Both plasma and LCD TVs display HD (high definition) signals for a sharper, more three dimensional picture. LCD TVs, however, have a slightly higher resolution (more screen pixels) then plasma TVs.

- Video Games

Plasma and LCD TVs are both great for video gaming, however because of plasma TV's tendency toward screen burn in, an LCD TV is the better choice if you play a lot of video games.

- Portability

LCD TVs are thinner and lighter than plasma TVs, making them easier to move and easier to mount on a wall.

Plasma vs LCD TV prices

When it comes to which type of TV gives you the most bang for the buck, it depends on what you're looking for.If you're looking for a large-screen TV – 42" or larger – plasma TVs are currently cheaper than than similar-sized LCD TVs. When I recently compared prices on 42" TVs, the cheapest plasma TV was $999, while the cheapest LCD TV was $1,367When it comes to mid-size TVs, I couldn't find plasma TVs smaller than 42." The cheapest 32" LCD TV I found was $619, while the cheapest 27" LCD TV was $550.
