All About Plasma Televisions
 

In article , says...


Most people know plasma TVs as those unbelievably thin display monitors that
can be hung on your wall just like pieces of video art. (To give you an idea
of the space-saving advantages of plasma technology, consider this: A
40-inch TV may be two feet deep and weigh upwards of 150 pounds, while the
same size plasma display might have a depth of, say, 6 inches and weigh half
as much.) But this isn't your average slimmed-down television set. The
display itself consists of thousands of "cells," which are individual glass
compartments injected with neon-xenon gas suspended in plasma-hence the
"plasma" appellation. These cells are the basic elements comprising the
picture you see on your TV screen. When the gases are electrically charged,
they strike red, green, and blue phosphors. Just like that, an image (which
is nothing more than the sum of the aforementioned colored elements,
commonly known as "pixels") is born.

They also fade over a reletively short period of time.
Not a good purchase.

"suspended in plasma"? Huh? "Plasma" is the ionized state of matter.

The gas is ionized by an electrical discharge and thus the name plasma TV.
It ionized gas results in the production of ultraviolet (UV) light. The
phosphors of each cell convert the UV to light - red, green, and blue -
3 cells for each pixel. A plasma TV is more like an array hundres of
thousands of fluorescent lamps than a CRT.

Bull****. Do your homework. They life is finte, but appear to be not much
differenct than a CRT. Early PDPs may have had short life than newer ones,
but even the worst units are not deserving of this description.

Not a good purchase.

That is a decision for informed consumers. For most people I would agree
that they are not a great choice, but for some people in some applications,
they are perfect.

Although I haven't the privilige (or cash) to have a Plasma TV, I have heard
"friends of friends" having to return their Plasma TV for some sort of
5-yearly "refresh", because the picture quality was fading. I understood
this to mean it was getting washed out.

Any other experience with this out there?
