LCD displays have been around for years in everything from cell phone screens to
computer displays. Like a plasma display they are made of two pieces of glass-like
material with liquid crystals sandwiched in between the pieces of polarized glass.
LCD displays are often called “trans missive” displays because the liquid crystals do
not actually create the light needed to display the images but actually control the
light and the amount of light coming from the display. Basically the display works
on the principal of blocking light emission. Depending on the amount of voltage
placed through liquid crystal they can control the amount of light that passes
through the liquid. The liquid crystal cannot create their own light so

light source is necessary and this is in the form of a special fluorescent light bulb.
This bulb placed behind the LCD panel and the light from the bulb is diffused by a
white diffusion panel so that the amount of light emitted onto the LCD is uniform.
The liquid crystals will control the amount of light that passes through the glass
panels and the inner working of pixels and sub pixels to form images and control
color. The LCD pixels act like tiny shutters that either open or close to let light in or
to block the light..
LCD displays can be made very thin. Since no phosphors are burned like in
traditional CRT television and Plasma

the light but rely on a back light; no radiation is emitted from the screen. Plasma
and CRT screens emit low levels of radiation. Another plus side to not having to
burn off phosphors to produce images LCD televisions use less electricity than
Plasma’s and CRT’s do.
Viewing angles used to be an issue with LCD displays. The early LCD display where
originally designed to be computer monitors thus meant to be viewed straight on.
Recent improvements have given the newer LCD’s better viewing angles than most
Plasma’s measuring in a 170 degrees on the high end models.
PRO’S
Very thin displays can be made. Makes LCD television a great space saver.
...think that a cheap price is always a bad price or a car which has substandard parts. There are forums all over the net with people who can backup a retailer and the models they sell. They can reassure you ...
Sharp images can be produced
Life span is longer than plasma. Some displays are rated up to 80,000 viewing hours
by the maufacturer’s
Back light bulbs can be replaced in some screens
Do not suffer from image “burn-in”
Can double as computer displays.
CON’S
More expensive than Plasma and rear-projection per square viewing inch
Screen sizes aren’t up to Plasma displays yet (current sizes range from 10″ to 45″)
Colors are not as vibrant as plasma displays and blacks and grays are not as deep
and well defined as on a Plasma television.
Motion trails (pixelation) with moving images
Viewing angles are reduced at about 20 degrees off
