Do you know what is differences between Plasma TV and LCD TV?

Answer 1

Well this on is right up my alley as a home audio/video installer so here it is.
.:: PLASMA ::.
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 ::.
CD 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.

The ADVANTAGES of Plasma over LCD are:

1. Larger screen size availability.

2. Better contrast ratio and ability to render deeper blacks.

3. Better color accuracy and saturation.

4. Better motion tracking (little or no motion lag in fast moving images).

The DISADVANTAGES of Plasma vs LCD include:

1. Plasma TVs are more susceptible to burn-in of static images.

2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images.

3. Does not perform as well at higher altitudes.

4. Shorter display life span (about 30,000 hours or 8 hrs of viewing a day for 9 years) than LCD. However, screen life span is improving to as high as 60,000 hours. due to technology improvements.

LCD television ADVANTAGES over Plasma include:

1. No burn-in of static images.

2. Cooler running temperature.

3. No high altitude use issues.

4. Increased image brightness over Plasma.

5. Longer display life (about 60,000 hours - at which time all you may need to do is replace the light source, not the entire set). This can vary according other environmental and use factors.

6. Lighter weight (when comparing same screen sizeds) than Plasma counterparts.

DISADVANTAGES of LCD vs Plasma televisions include:

1. Lower contrast ratio, not as good rendering deep blacks.

2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts) - However, this is improving.

3. Not as common in large screen sizes above 42-inches (although the number is growing).

4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you.

5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions, especially when comparing EDTV Plasmas to HDTV-LCD Televisions.

Answer 2

a plasma tv is a different technology, where they use plasma energy to generate picture, which becomes very hot, so the tv won't last you for over 10 years. A lcd means liquid crystal display, and it is promised to last you longer, it is better for gaming, and playing dvds. So in general, a plasma tv has great picture, and you shouldn't play dvds in it. So you should go with an lcd tv.

Answer 3

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.

Answer 4

Plasma displays utilize two pains of glass between which a gas (plasma) is trapped.. in the gas is a chemical called Xenon, turning the TV on induces a reaction in the Xenon that creates light photons, in varied colors, and thus an image.

LCD utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light, creating an image..

Plasma screens because on their inherent gaseous composition tend to be les clear from any angle beyond 90 degrees.. so you really need to be sitting right infront of a plasma screen to see it best.. whereas with LCD monitors, the individual pixelated effect of the crystal keeps the image sharp from pretty much any angle you view the screen at.

And the above answer is wrong, HEated Gas is Plasma in reference to electronics.. the Chemical in LCF screens is refered to as Liquid Crystal.

Answer 5

plasma is flat in front and almost flat on back
LCD means the screen is composed of that liquid looking stuff like on lap tops.
hence a plasma can be lcd
