IT IS. Another flat panel technology,
this contains
chambers of plasma gas
_br each pixel. The plasma pLxels are made to glow by a network of electrodes.
Plasma is the king of the "wow _hctor" technologies--giant-screen
televisions
currently
up to 63 inches diagonal, yet svelte enough to mount on the wall, in an
armoire or on a tabletop stand. Even large plasma TVs can be as thin as 5-1/4 inches.
The picture is only part of the beauty.
BENEFITS.
Because
the screen brightness
comes _om the plasma itself', these
panels have a wide viewing angle.
Plasma models have wide 16:9 aspect ratio
screens and a high enough pLxel count to achieve HDTV-Ievel
resolution.
Unlike
LCDs, plasma panels are broadly available
in larger screen sizes. Plasma panels also
need no convergence.
And they need no magnetic
shielding _om your loudspeakers.
LIMITATIONS.
Although today's plasma panels offer excellent picture quality,
their black levels and contrast still cannot match CRTs. Unlike LCDs, plasma can be
affected by image retention and "burn in." Care needs to be taken when selecting
aspect ratio and using videogames
to avoid the possibility
of image retention.
Plasma
panels can generate an acoustic buzz when used at high altitudes (altitude more than
6,200 feet above sea level or air pressure less than 800 hPa). This is caused by the
difference
between the pressure
inside the panel and the pressure
outside.
