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. About the author:
