Plasma & Lcd Televisions
Plasma versus LCD - a fascinating, complex battle indeed!
LCD and plasma TVs each have their own characteristics.
And the decision about which one you prefer has a lot to do
with your personal taste, much like preferring a peanut butter
sandwich to a jelly sandwich, or vice versa.
Let us proceed point by point.
Each pixel in plasma TV is made up of three phosphors - one
red, one blue, and one green. They emit light when struck by
beams of electrons. The quantity of light emitted depends on
the intensity of the electron beam. It is the phosphors
themselves that create the light one can see on a plasma
screen.
On the other hand, LCD TVs use millions of crystal, which are
suspended in a liquid that is sandwiched between transparent
panels. A bright florescent light is in place behind this liquid
crystal sandwich. The crystals are instructed to either let the
light pass or block its passage. Color filters are used to
determine color.
As far as size is concerned, both TVs were always thin, and so
that question is something of a stalemate. For example, the
difference between 3" and 5" seems to matter in case of certain
models, but becomes almost immaterial when it comes to a
large-screen TV.
In terms of the viewing area, however, plasma TVs have always
been known for their larger sizes. And that holds true in general.
Put in a different way, one will have a greater variety of plasma
TVs to choose from when he/she is looking at the big models.
But it should be kept in mind that LCD TVs, too, are steadily
gaining ground.
Now comes the question of price. For large-screen plasma TV
and a large-screen LCD TV of the same size, the plasma TV
would normally cost less. LCD TVs are, however, dropping in
price, and it is highly likely that the two will be on equal footing
in the price department quite soon. All else being equal, in the
plasma vs. LCD TV battle, plasma tends to win on this one for
the time being. But the battle goes on.
