What are Plasma televisions?

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.
