LG TV - When to choose between Plasma and LCD TV

Many people know they want a flat-panel TV, but aren't sure which type to get.

A plasma TV might be for you if:

- You want really rich, warm colors and deep blacks.
- You'll be sitting off-axis when you watch TV or movies.
- You don't watch a lot of TV shows or play lots of video games with static images on the screen for more than a few hours at a time.
- Your viewing room doesn't have a lot of ambient light, or you can easily reduce the light by closing the blinds, for example.
- If you're looking at screen sizes under 40", LCD is your only flat-panel choice. LCD looks great in a kitchen or any other room with bright lighting. LCD displays are better at resisting glare from sunlight or room lights, and they're very bright (brighter even than plasmas). LCD is also one of the most rugged display types. Its total immunity to screen burn-in makes LCD an ideal choice if your viewing includes frequent computer or video game use. And if you leave your TV on for hours at a time tuned to a news or sports channel with a scrolling "ticker," LCD would be a safer TV choice.

A flat-panel LCD TV might be for you if:

- You watch a lot of TV shows or play lots of video games with static images on the screen for extended periods of time, multiple days a week.
- Your TV room is relatively bright, or you do a lot of daytime viewing.
There are many more 1080p LCD models than plasma — that's the highest resolution currently available, so you'll see a very sharp, detailed picture.
- LCD TVs are usually more energy efficient than plasma models of the same size.

Outward Appearance

Outward apperance are definitely deceiving when it comes to LCD and Plasma televisions. Although both types of televisions are flat and thin, they employ different technology in an attempt to deliver similar results.

Plasma TV Overview

Plasma television technology is based loosely on the fluorescent light bulb. 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.

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
