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.

Plasma TVs And Your Home Entertainment Center
by: John Rivers
It seems as if everyone these days is showing off their expensive flashy new home entertainment centers. They?re linked wirelessly to computers, have more speakers than a Rolling Stone?s concert, and cost more than a midsize luxury sedan. They feature DVD players, DVR or Tivo, CD players, MP3 players, and anything else you can imagine. The centerpiece, though, still remains the same: the television.
