Now a status symbol among the rich and wealthy, a plasma TV is a high-definition (HDTV) alternative to the standard cathode-ray televisions sold today. It gives viewers sharp
images and vibrant colors, particularly when used in conjunction with high-definition broadcasts. A quality plasma TV, however, does not come cheap. Its price ranges from $4,000 to $15,000 plus.
One of the main attractions of a plasma TV is a flat screen,whichcan be mounted directly on a wall. Manufacturers often employ surround-sound theater speakers and high-end receivers to complete the feeling of luxury. No wonder plasma TVs are such a craze these days.
In terms of science, 'plasma' refers to inert gases like neon and xenon that glow when in contact with an electrical field. Televisions usually rely on thousands of small 'picture
elements', abbreviated as pixels. A bundle of three distinct colors, usually red,green and yellow, constitute one pixel in a color TV. Properly controlling the level of each color, all of the other colors of the spectrum can be produced in each pixel. The distance between the viewer and the screen is usually such that the individual pixels blur into each other
and the illusion of motion is created as they change color.Plasma or not, this holds true for any television system.
The individual pixels in a plasma TV are made from three tiny containers of an inert gas like neon or xenon. There are thousands of these tiny tubes on an average plasma TV screen.
All of them are sandwiched between two electrically charged plates. And plasma glows when exposed to an electrical current.A cable or broadcast antenna dispatches signals to a
computer-processing unit.The antenna instructs the unit how to reassemble the entire picture hundreds of times per second.
A plasma TV screen contains more pixels than a standard television, so the image is noticeably sharper. If light conditions are ambient, a plasma TV will perform at its best. As flat screens have a viewing angle of 160 degrees, one can watch TV from almost any position in a room.

Plasma Televisions For Sale
Televisions previous to the Plasma TV explosion used the (CRT) cathode ray tube to give users the ability to watch television. CRT televisions works by shooting out a beam of negative charged particles called electrons into a large glass tube. These negative electrons
For the past 75 years, the vast majority of televisions have been built around the same technology, the cathode ray tube (CRT). In a CRT television, a gun fires a beam of electrons (negatively-charged particles) inside a large glass tube. The electrons illuminate phosphor atoms inside the tube (screen), this allows the TV picture to be produced by illuminating different areas of the phosphor coating, this is what gives you the CRT television.
Now welcome to the new face of television, Plasma TV. Plasma has taken the home theater market by storm because of their amazing picture quality and very thin design. The idea of plasma display panels began in 1964 at the University of Illinois. The first displays were very primitive using only points of light created in the laboratory. As time went on digital processing, and other technology, made vivid plasma displays a reality.
Plasma televisions use a much different type of technology thatn CRT models, they use something called pixels. Using a video signal the pixels on the flat screen light up with a high-energy beam of electrons that are separated into the 3 primary colors, red, green and blue. From the illuminated fluorescent lights pixels you get the full color spectrum that produces a full range of colors that give you the image on the screen. Each pixel on the screen has three fluorescent lights in it, a green, red and a blue fluorescent light. Each fluorescent light in the pixel can produce 16 million colors, giving you amazing colors and overall picture quality that you can't finder in regular CRT televisions.
Another feature that you can't find in CRT TVs is the widescreen design found on Plasma televisions. The (16:9) aspect ratio is the same dimensions used in movie theaters. This feature gives Plasma flat screen high definition television models a cinematic feel, that is great for watching feature films, concerts, Monday Night Football or anything else you can imagine.
And unlike conventional television models, there are no scan lines on plasma televisions, so the picture is much sharper. The viewing angle is far superior than CRT, there is 170 degree viewing angle so you can basically watch the TV from any area in the room. As I mentioned before Plasma Tvs are very thin, only 3.3 inches in width. This makes them perfect for hanging on your wall, freeing up space in your home. Just like a picture frame, you can now hang your television on your wall!
So who manufacturers these thin TV displays? You can choose from numerous brand names which I'm sure you are familiar with such as, Sony, Sharp, Hitachi and Samsung to name a few. Plasma isn't the only technology available if you are a HDTV buff, you should also check out LCD televisions and rear projection TVs.
And if you want to find a cheap plasma TV, check out the discount deals available through internet, particularly Amazon.com and Ebay.com. Those 2 online merchants are trusted and can offer not only new, but used and refurbished models for even bigger savings.
