LCD
For the LCD TVs, screens
are available to a maximum
diagonal size of 60 inches.
 They are more expensive
than the Plasma TVs.
 LCD TVs don`t consume
as much as the Plasma TV.

There are displays with a
size of almost 65 inch
diagonal measurement.
 They are cheaper than the
LCD TVs.
 Plasma display consumes
much more energy than a
LCD display.

Comparing LCD and Plasma
LCD
Liquid Crystal Displays (LCD) works by
filtering light when it gets an electric charge.
These liquid crystal cells are placed between
two glass plates and the voltage is received
from a matrix composition of thin film
transistors [TFT].
 LCD TVs costs more than Plasma TVs and
have smaller size (maximum of 60 inches).
 LCD displays consume 30% less than Plasma
displays and they don`t have problems with
Screen Burn In/ Ghosting.

LCD TV – FULL COLOR DETAILS

In the case of picture quality, LCD displays
are more advantageous than Plasma displays ,
because it is apt for public display as well as
at any time of the day. They show the images
with full colour detail.
The LCD is disadvantageous in playing fast
movement video because, they have a
motion blur and lesser time response. The
blur causes the pixels to be out of their
position causing the image to be blurred.


Plasma display, gases like xenon and neon
are excited by electric pulses produced by
the electrodes. This excitation causes energy
to be produced in the form of light. The
display also contains millions of individual
pixels.
They are cheaper than LCD TVs and are
available in bigger sizes.
Plasma TVs needs to light up all the pixels
used on the screen. This also includes the
pixels that produce the dark images. This
causes a lot of electricity to be wasted.

Plasma display also suffer with Screen Burn
In/ Ghosting. It occurs because the glass
display tries to permanently etch the colour
that has been displayed for a long time.
The plasma display is not so apt for
computer screens as they have the problem
of ghosting.
Their contrast levels of playing fast videos
are way higher than any other displays they
are good in displaying fast moving videos.
Example of Ghosting
Decision

I`d choose the LCD TV because it
consumes less energy, has full color
details, doesn`t have Screen Burn In/
Ghosting and lots of other positive
factors.
