Between LCD And Plasma TV
When it comes to
flat TVs, two technologies come to mind,
LCD (Liquid Crystal Display) and Plasma. A
lot of people are puzzled about these two
types of flat screen technologies and
choosing between them can be quite a
bewildering task. If you need to compare
LCD to Plasma TV, you may find something
useful in the following
information.
Flat Screen
Technologies Compared
The LCD screen is
comprised of two clear panels that have a
crystal-filled liquid between them. These
crystals reposition themselves to either
block light or let light pass through and
the result of millions of crystals doing
this is the picture on the display. The
action of the crystals is triggered by
voltage.
Plasma TV, on the
other hand, is composed of millions of
small glass cells filled with rare gases
such as xenon and neon. These cells are
lit by phosphors that are activated by
electrodes. Each cell contains three
different colored phosphors - green, blue
and red. Like in the LCD screen, the
combination of the millions of cells forms
the image on the display.

Quality and Performance
Compared
Brightness -
according to independent viewers, LCD TVs
are brighter than plasma TVs. On the
average, plasma screens have brightness
ratings of about 100 candelas per square
meter while LCD TVs have around 450. This
perception of this brightness is of course
dependent on where the TV is located and
what is being watched.

Plasma TV" information continued
....
Contrast
Ratio - contrast ratio
measures the distance between the
darkest and whitest display of
the TV, a high ratio means
greater details can be discerned.
In the real world, LCD TVs
reportedly have higher contrast
ratios which can amount up to
450:1 compared to 200:1 for
plasma TVs.
Color
Saturation - color
saturation measures the accuracy
of the colors on screen based on
the present of gray shades,
higher gray shades results into
lower saturation. Plasma TVs are
famous for their high color
saturation due to the method it
emits light. The ability of
Plasma pixels to be turned off
when they are not in use prevents
the emission of stray light that
diffuses color. This is why tints
and hues in Plasma TV are
noticeably more vivid and
vibrant.

Size - plasma
TVs are generally larger than LCD
TVs. Plasma TVs can be as big as
60 inches but can only be as
small as 32 inches. LCD screens
can be as small as 13 inches but
no larger than 46 inches. Sizes
beyond these ranges are being
developed, however.
Viewing Angle -
pictures in plasma TVs are still
clearly discernible at about 160
degrees and even 180 degrees for
some models. With LCD TVs
however, the picture becomes dull
beyond 100 degrees.
