Plasma and LCD TVs are the latest trend in home entertainment. Both offer unrivalled picture quality and resolution, while doing away with the bulkiness of the older rear-projection technologies. But with all of the hype surrounding these two types of televisions, what is the difference between them? Although they look- and are virtually priced- the same, they are not.

There differences are found in the way in which they display their pictures. Plasma TV technology is made up of hundreds of thousands of little pixels, each capable of displaying red, green, and blue colors. A plasma monitor often consists of two panels, which are filled with an inert gas, such as xenon or neon. When the pixels are excited by pulses of electricity, the gas becomes liquid, thus generating light. This light in turn then illuminates the pixels, causing them to display the appropriate color to form a picture.

LCD panels function in a very similar manner. A panel of thin-film-transmitters, or TFT, sends electricity to cells filled with liquid crystal. When the cells are struck by the electricity, the liquid crystals allow light to filter through. Unlike the pixels found in plasma TVs, LCD monitors create color by blocking out the appropriate wavelengths from white light.

So which is better? The answer to this question depends upon what you plan to use TV for. Do you just want to use it to watch movies and television? If so, then a plasma TV might be best, because they are capable of a higher better color saturation and contrast than their LCD counterparts and for displaying moving images. If you plan in spending a lot of time showing digital photography or plan on using the monitor with your computer, then a LCD display might be better suited to these purposes.

Both plasma and LCD technologies each have their advantages and disadvantages and your decision should ultimately be based on your monitor's application.

Answer 3

There are technological differences, but I'm certain you want to know what the differences mean to you as a consumer, right?

Plasma is the best technology for representing a "true" picture image- that is, it displays the blackest blacks, and has best contrast ratio (the comparison between light and dark images)

HOWEVER, it is also the most expensive and is susceptable to "image burn-in"- a static image left to display on screen may permanently "burn" itself onscreen, and you'll see that image there forever.

LCD is based on liquid crystal display- the same technology that our calculators use. The technology is cheap, however the colors and blacks aren't as striking as plasma. There is also a "screen door effect" apparent on screen. That is- when you look at the picuture closely, you'll see each individual pixel separated by what looks like a "screen door".

Which is better? That is entirely up to you and your budget. Both have equally strong pros and cons, I could type forever and ever about them (I used to sell them for a living) but I can only suggest that you go to a reputable store and check ouyt the differneces yourself.

Ignore the tech talk- which picture looks better to you?

Answer 4

Plasma screens TV is a flat-panel display technology that ignites small pockets of gas to light phosphors. Whereas LCD is an older technology that has been used in our Computer monitors for years........
Dont have much idea about the LCD technology know-how but you can use the link below....

Anyways, Plasma results in a much better color resolution....

Answer 5

There are a number of differences from viewing angles to burn-in to contrast ratios and to screen sizes.

In terms of technology a plasma surface consists of over a million tiny glass cells that are charged with a mixture of neon and xenon. Each cell has a coating of phosphors that emit light when energized - one red, one blue, and one green. To dispaly a signal, an electric current flows through the flat screen, causing the plasma inside to give off ultraviolet rays. This light in turn causes the phosphor coatings to glow the appropriate color. These RGB cells change intensity to give off a rich, vivid image on your plasma TV.

In LCD TVs liquid is suspended between two transparent polarized panels. One of these panels holds the liquid crystals. When electric current is passed through individual crystals, it determines which of the crystals allow light or not to create an image i.e. the crystal reposition themselves. The crystals do not produce light, they just direct it. Fluorescent tubes behind the panels supply the light source to create the image. Both the lit and unlit crystals create visible pixels that combine to give the clear pictures.

Answer 6

LCD is Liquid Crystal Display it uses light to light up the screen which can be good because it is less expensive but the pictures is still more than adequately defined but not as well as a plasma, which uses gas to light up the picture. the picture is better than the LCD but cost is also higher

Answer 7

LCD is Liquid Crystal... and i disagree with one of the other answers, Plasma is not better/longer lasting.. as it only has a lifetime of max 10 years.. and will have to be Re-Gassed... Whilst Lcd will last for much longer, therefore a much BETTER option

Answer 8

one is liquid crystal display the other is plasma.... LCD is cheaper but a plasma screen will last longer

Depends on what you want to know?
Hopefully this will help you. If you are wanting to know which is better then I got that one for you too. Hope this helps
