How
a Plasma Television is Made
As HDTV style becomes more and more prevalent
so does the emergence of flat-panel (or flat screen) televisions.
The biggest development in the technology of television since
the inception of color TV is considered to be these convenient,
lightweight televisions that display sharp, clear images. Plasma
televisions are one of the newest and most creative innovations
in home entertainment today. In fact many people when talking
about plasma screens say that the quality of the images is
both richer and more “cinematic” than other types of televisions.
But what technology is used to construct this newest rage
in the electronics industry? Let’s take a closer look at how
a plasma television is made.
The technology utilized in its construction is really very
elementary on one level. A plasma television makes
use of a fluorescent bulb as its primary power source. Cells make up
the display of the plasma television and within each cell there
are two panels made of glass, which are in turn each separated
by a narrow gap of space. It is by way of this narrow gap that
a gas known as neon-xenon is injected and then afterwards sealed
in plasma form. During the process of its being manufactured,
when the plasma is being used the gas is then electrically
charged at specifically timed intervals. Precision and timing
are the name of the game for the process to be done at top-notch
form. The charged gas in the television comes into contact
with three different colored phosphors (those being red, blue
and green) and it is this action that produces the television
image we see when we look at the screen. Every individual group
of red, blue and green phosphors form a pixel or a picture
element. A pixel is basically small dots that generate light
and come together to form a video picture.
Plasma televisions have measurements ranging anywhere from
32 to 70 inches in a diagonal direction and only 3 to 4 inches
in regards to depth. The HDTV viewing on a plasma screen is
considered to be of superior quality and because of the wide
viewing angle; the plasma set is believed to be an excellent
choice for a true home theater experience. The clear,
smooth images you see on a HDTV plasma screen are due to the
almost
3,000,000 pixels that are illuminated in a special order for
this purpose. The cells in plasma televisions are bonded together
in such a way that they are able to boast color combinations
in the range of 16 million (and in some cases, even more).
If you couple this with the fact that the plasma television
has no beam like a traditional CRT television does then you
will understand why the plasma HDTV screen has exceptional
image clarity, light output that is uniform and an almost perfect
focus of pictures.
It was near the end of the year 1999 that plasma screens appeared
on the United States electronics market but the idea behind
then was created much further back then that. The plasma concept
first began to take root at the University of Illinois in July
1964. Experiments performed in laboratories created points
of light that were the precursor to plasma technology that
was to come. The technology continued to be a hot topic for
researchers and scientists as they tirelessly worked on developing
and improving their ideas for plasma screen construction. It
was by the late 1960’s that enough advancement had taken place
to allow scientists to develop geometric shapes from plasma.
We’ve come a long way since that time. In today’s ever evolving
electronics world, plasma displays that make full use of color
and brightness are a reality thanks to advanced technology
in the manufacturing field, improved materials and digital
processing of a high-speed nature.
Digital television is considered the present trend and one
that will be utilized more and more as we pave the way into
the future of technology. Those who study these things closely
say that due to the creation of HDTV, DVD-Video, digital broadcasts
via satellite and computer video we are presently in a sort
of digital video revolution. With the growing popularity of
HDTV plasma screens this revolution does not appear to be losing
any steam.
