Although plasma
TV is a term that's being bandied about
frequently in the market, many people are
still confused as to what plasma TV is all
about. If you're one of them, here's what
you should know to prevent you from making
an uninformed purchase in the
future.
What is a
Plasma TV?
A plasma TV set
makes use of flat screens unlike
cathode-ray-tube or CRT TV sets, which was
the TV set for older generations. If
you're still using an old TV set in your
living room, it's probably a CRT TV set
and one way of identifying it is by
checking its screen type. If it has a
rounded screen, that's definitely a
CRT.
Although plasma
technology was discovered in the 1960's,
plasma TV sets have only been introduced
to the market in the 1990's, making any TV
set manufactured before that decade is
more likely a CRT TV set.
The flat screen
of a plasma TV set is made up of minute
pieces of bubble-shaped glass. Each piece
of this contains plasma, thus the term
plasma TV. Each piece also represents one
pixel. This pixel can be divided into
three parts, represented by one color
each: red, blue, and green (yes, yellow, a
shade that joins red and blue to make up
the triumvirate of primary colors, is not
included). These shades make up the
acronym RGB, and it's a term that will be
frequently used in any video-related
topic.
Now, for a plasma
TV set to show an image, a current of
electricity must first pass through the
plasma TV set's screen. This will cause
the plasma substance inside the pixels to
react and cast off ultraviolet rays. Each
pixel will glow or dim appropriately to
form a perfectly vivid image.
The
Multitasking Life of a Plasma
TV
Plasma TV can
display images that make use of either
standard or HDTV format. This is an
advantage that you can't expect to enjoy
with a CRT TV set. Plasma TV can also
display images straight from home-recorded
videos. Lastly, a plasma TV set can not
only serve as a television set but as a
computer monitor as well if you so
wish.

If you
are planning to use your plasma
TV set as a computer monitor, be
aware that if you're looking for
a compact plasma TV, you might be
better off choosing an LCD TV
monitor instead. Plasma TV sets
are generally manufactured with
large-sized models while LCD TV
sets are manufactured with
smaller and compact-sized
models.
The
Difference between LCD and Plasma
TV Sets
A plasma
TV set obviously makes use of
plasma to display images. A LCD
TV set, on the other hand, makes
use of liquid crystal to create
the appropriate images in its
screen. Both TV sets are engaged
in a battle for the honor of
being the best TV technology
today.

What
and What Not to Expect from a
Plasma TV
Plasma
TV sets will definitely produce
better images than CRT, but
whether it can also produce the
same results over an LCD depends
on your opinion.
Although
programs using standard TV
formatting will look better in
plasma TV sets than in CRT, don't
expect your plasma TV set to
perform miracles. It can only
make the images look more vivid
but it cannot correct essential
errors where standard TV
formatting is to blame. If you
want to make full use of your
plasma TV set, stick to watching
programs that make use of HDTV
formatting.
