What is the difference between plasma tv and lcd tvs?

PLASMA TV Overview : Plasma television technology is based loosely on the fluorescent lightbulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element). Although Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images. LCD TV Overview : LCD televisions, on the other hand, use a different technology (see also question #1 for this same explanation). Basically, LCD panels are made of two layers of transparent material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer. Unlike standard CRT and Plasma televisions, since there are no phosphors that light up, less power is need for operation and the light source in an LCD television generates less heat than a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself. FOR MORE PL. VISIT: http://hometheater.about.com/od/lcdtvfaqs/f/lcdfaq2.htm

Some of the operational differences are that Plasma TVs use more electricity than LCD TVs, are easier to "burn-in" (created ghost images from long lasting displayed images), do fade in brightness with age, and are usually costlier than LCD TVs. Plasma TVs however have the brightest and clearest displays of LCD TVs have a limit to the size they can be made to (I think it is now 42"), can have pixels go bad (meaning they do not change to the correct color displayed in the picture), and can have "blurry" motion (caused by slow change of pixels.). They don't suffer from burn-in like Plasma and CRT TVs, are fade-resistant, and are usually a little cheaper than Plasma. The brightness and clarity is very similar to Plasmas also.

lcd tv's are costlier while plasma tv's are finally affordable now. lcd's work on liquid color display and have better image quality.

Plasma TVs are normal TVs we see daily in our day to day life and LCD TVs are the new generation TVs these are based on liquid crystal display,this technology uses less power and was being used in calculators.The LCD TVs has the benefit of being slim and trim and can be used as a wall hanging.
