Each type of
technology used in making flat screen TV's is
different and carries its own set of advantages
and drawbacks. Learning and recognizing those
qualities will enable you to make the best
choice possible when shopping for you new
Plasma, LCD or DLP TV screen.
Plasma TV screens have an advantage of automatic
pixel shift technology, which gives the plasma
screen a resistance to being damaged by burn in.
Of course, the best prevention for decreasing
burn in onto your TV screen is not to allow an
image to sit on the screen for any length of
time.
Plasma TV's are able to create deeper blacks and
even better contrast. Plasma also has the
advantages of response time, in depth color and
is available in larger screen sizes than any
other current technology. In plasma TV screens,
the size usually starts at 42 inches and
upwards. However, a plasma TV does generate more
heat and is more prone to display dysfunctional
problems due to its change in temperature.
Since Plasma TV's are temperature sensitive,
some of them suffer performance problems at high
altitudes. Although some manufactures produce
plasma TV's that are compatible with high
altitudes, but they are more expensive that
standard made plasma TV's.
The average screen size of plasma TV's vary from
32 inches to 63 inches, with a 160-degree angle
of viewing. Plasma TV's are able to display
rapid movement of a video and refresh as well as
traditional TV's. Being heavier in weight a
plasma TV may require the strong support of a
weight-bearing wall while being mounted.
LCD has the advantage of not being inclined to
respond negatively to high altitudes, although
LCD technology has yet to produce a screen size
of over 37 inches due to problems with bad
transistors that distort a quality picture. It
is possible to use LCD TV screens as computer
monitors, as they normally do not suffer burn
in, though a ghosting of images may appear on
screen due to a pixel charge being retained on
the viewing screen. However, LCD TV is also
prone to have problems displaying programming
from satellite and cable signals.
LCD TV's have a lower contrast ratio that does
not produce deep blacks. When their individual
pixels burn out, the screen will be marred with
tiny missing areas of white and black.
Individual pixels cannot be replaced; therefore,
the whole screen will need to be replaced. LCD
TV's are also less expensive and lightweight
which makes for easier transport and
installation. Many new LCD TV owners install
their on sets easily thereby saving even more
money relating to purchase of a new TV. LCD TV's
are able to maintain their option levels in
well-lit rooms, as they do not reflect much
light. LCD TV's also run cooler than plasma
TV's.
Most consumers are satisfied with the quality of
brightness of both plasma and LCD TV's. As far
as thickness of the screens, a plasma screen can
be as thin as three inches and an LCD screen can
be as thin as two inches. The estimated life
span of plasma and LCD TV's seem to be a length
of 15 years and up with normal viewing habits.
DLP TV's are usually less expensive than LCD or
plasma TV's and they also have the advantage of
creating the best quality of picture. DLP TV is
also able to HDTV at its fullest resolution.
Moreover, they usually do not require
maintenance. However, there have been noticeable
rainbow effects in the DLP components that
employ certain color wheels, as well as DLP
having a limit of angle view.
