| According
to Plasma.com, a plasma tv is "a flat,
lightweight surface covered with millions of tiny glass bubbles. Each bubble
contains a gas-like substance, the plasma, and has a phosphor coating. Think
of the bubbles as the pixels. Now, think of each pixel-bubble as having three
sub-pixels - one red, one green, one blue. When it is time to display an image
signal (RGB or video), a digitally controlled electric current flows through
the flat screen, causing the plasma inside designated bubbles to give off
ultraviolet rays. This light in turn causes the phosphor coatings to glow
the appropriate color making your Plasma TV provide the best video image
anywhere." TechEncyclopedia states that plasma displays, or gas discharge displays, are "a flat-screen technology that contains an inert ionized gas sandwiched between x- and y-axis panels. A pixel is selected by charging one x- and one y-wire, causing the gas in that vicinity to glow. Plasma displays were initially monochrome, typically orange, but color displays have become increasingly popular with models 40 inches diagonal and greater being used for computer displays, high-end home theater and digital TV."

There
are numerous uses for Plasma Televisions besides simply updating your home
theater system with the best possible picture whilst saving space. The following
are ideas from the TV Authority.
|
| There
are numerous manufacturers of plasma televisions. Home Theater Magazine states that "Sony, NEC, and Gateway units are
considered consumer models, while the
others are labeled as commercial or professional models. They are sold through
commercial distributors for use in business and/or industrial locations.
You won't likely find these models at your local Best Buy or independent retailer,
and the manufacturers normally wouldn't promote these products for home theater
use." |

Sony Electronics |
Panasonic |

| Philips |
Samsung |
Hitachi |
Zenith |
Gateway |
Depending
on the brand, each unit has different specs, but here are some of the basic
features shared by all manufacturers.
|
Depending on the size of the television set,
you could pay anywhere from $3000 to around $20000 for your plasma television.
The most reasonably priced unit on the market is a 42-inch Gateway
for $2999. The Plasma TV Buying Guide provided the following chart of the
ten most popular displays and their retail prices. Also, for more detailed
information by manufacturer and screen size, click here.

| According
to the
Plasma TV Buying Guide, "the concept for plasma display panels was first
conceived in July 1964 at the University of Illinois. The first displays
were nothing more than points of light created in laboratory experiments.
From then on, the technology was developed and improved and by the late 60's,
it had become advanced enough to allow the scientists to construct geometric
shapes. Further development was limited, scientists were restricted by the
materials that were available, so screens were small, and image quality
was low. Today the progression in high speed digital processing, materials
and advance manufacturing technology, has made full colour, bright plasma
displays possible." |
InfoComm had an article concerning the market penetration of
plasma televisions. It stated "TFCinfo Corp reported in its latest U.S.
Plasma Market Analysis Report that the global Plasma Display Panel (PDP)
market will grow by 87 percent to 1,067,000 units in 2003. Due to increased
resolutions, better scaling algorithms and sharply lower prices, the use of
PDPs has increased tremendously in 2002 and will continue its rapid growth
in 2003. TFCinfo also reports that the global market for PDPs will grow at
a compounded annual growth rate of 82 percent through 2005. At present, the United States is the smallest PDP market
among the top three world regions, behind Asia and Europe. We accountfor less
than a quarter of the global PDP market. Yet, U.S. PDP penetration will increase
markedly in the next few years. Market growth will outpace other regions
due to initial low penetration, early U.S. economic recovery and growing
consumer interest in digital TVs. In fact, in the third quarter 2002, U.S.
plasma displays used for consumer applications (home entertainment) surpassed
the use of plasma displays by businesses for the first time." See

I
could not find much on regularoty concerns regarding plasma TV's, but Plasma
TV Buying Guide does warn about fraud companies who are offering prices
that are too good to be true. The following companies were all found to be
set-up solely to defraud customers into
wiring large amounts of money overseas.

| Plasma televisions will without a doubt become
more successful than they already are. As prices continue to drop, and with
manufacturers like Gateway releasing
extremely competitively-priced units, the number of plasma sets purchased
are guaranteed to increase. Also, with the change to Hi-Def just around the
corner, consumers are sure to buy plasma TV's because of their space-saving
design and incredible picture. It is in the very near future that almost all
home theaters will be centered around a plasma TV hanging on the wall. Since
plasma sets are state of the art, if they were to one day become obsolete,
it would be decades into the future. This technology will be with us for a
very long time. |
