Plasma TVs have become increasingly available, and their cost is
lowering all the time. We have all heard about plasma TVs, and
advertising campaigns are constantly telling us that they are
the status symbol to have. Adverts are extremely effective at
glorifying the benefits of having a plasma TV, so much so that
it appears that even our pulling power and popularity will be
improved. The one thing that these adverts don't really tell us
is what a plasma TV actually is. Here is a brief guide to plasma
TVs to help you appreciate this apparent miracle of modern
technology.
Plasma TVs have a higher resolution than other conventional
display devices which means that they can display the high
definition signals of HDTV and DTV. Also, plasma TVs are
compatible with the computer signals SVGA, VGA, and XGA.
Unlike other display devices, plasma TVs have a transistor
electrode for every pixel cell which means that there are none
of the scan lines that are visible with regular TV sets. The
whole image is evenly lit across the display by these
electrodes, and not produced by an electron beam which is the
cause of scan lines.
Top-of-the-range plasma TVs have display capabilities of over 16
million colours. This ensures that the picture has far more
realistic colour than that shown on a conventional TV screen.
This is because they are able to show far more shades of colours
compared to the lesser quality TV screens.
Plasma TV screens are completely flat which has two benefits.
There is no edge distortion, unlike on more curved conventional
TV screens, and also there is a far wider viewing angle. The
viewing angle of a plasma TV is 160 degrees, and allows the
image to be seen properly from more areas of the room where the
TV set is situated. This makes plasma TV screens ideal for large
groups to view, and lessens the need for more than one TV set to
be placed.
Of course, the main benefit that most people are aware of with
plasma TVs is their space-saving quality. They are extremely
shallow, and can therefore be installed in many more locations
than a conventional TV set. The depth of a 50 inch screen is
approximately 4 inches, and it can therefore be hung on a wall.
