Flat Screen TV's are a big industry. Some statistics put it at about a billion dollars each year. There are three major types available.
(prHWY.com) November 15, 2012 - Charleston, AR -- The Liquid Crystal Display (LCD) TV, the Plasma TV, and the Light Emitting Diode (LED) type TV. LCD TV's are made from layers of plastic or glass. The LCD TV is light weight, uses less energy compared to other types, and is quite thin. This allows the TV to be hung on a wall without being an obstruction.
Some critics say that the LCD TV reproduces colors unnaturally. This is a matter of taste, though the colors can be quite bright, and skin tones tend to be flat. Fast motion action scenes, such as a ball game

LCD TV's are getting better with the higher refresh rates that are now on the market. LCD TV's are fragile and can develop dead pixels. Dead pixels usually appear as a black or blue speck in the screen. An LCD TV's lifespan is about 30 to 70 thousand hours.
Plasma TVs depict low light or shadow areas the best. Skin tones are more natural and colors are saturated and not so glaring as on an LCD. Plasma screens use 3 layers to contain a mix of noble gasses: xenon, neon, and helium. Plasma TV's lifespan is about 50 to 90 thousand hours. Plasma TV's are heavy. Although plasmas are getting more efficient, they still use more energy than other options. There is also the potential for burn-in. An LED TV is a good compromise. There is RGB Dynamic LED's and Edge-LED's. This type of TV offers a good balance between the LCD and plasma TV's. Though the LED TV uses an LCD screen, the back light makes all the difference.
