LCD computer monitors are very thin flat screen computer
monitors and replace an existing computer monitor but are lighter
and take up considerably less desk space. They range up to
46-inch in
size and come in several sorts. These LCD monitors accept
computer input, making them ideal for corporate, government and
educational use. Large LCD's are very impressive
for exhibition stands and reception areas, especially mounted as
video walls.
LCD TV monitors can be connected to a video recorder and
satellite system and display a TV image. Generally, they do not
have computer input, i.e. solely for TV and video use. LCD

LED TV's Traditionally, LCD computers and LCD TV's have a cold
cathode ray tube (fluorescent lamp) as a backlight. Manufacturers
are now including 'LED TV's' in their range. These are LCD TV's with
LED backlights. LED's (light emitting diodes), give off little heat,
are long lasting and energy saving, with the benefit of lower power
consumption.
There are two ways to use LED backlights in LCD TV's. Using an array
of white LED backlights, the fluorescent light is replaced by LED's,
thus making the LCD TV more energy efficient. Where local
dimming
technology is used, this tailors the brightness of each individual
LED to the image on the screen, to give deeper deeper blacks and
authentic colour reproduction.
The second way, is to use LED's around the inside edge
(edge-lighting) of LCD TV's, pointing in and running at full power
to flood the screen with light, which enables manufacturers to
produce much thinner screens, making these ideal for wall mounting.
Although LCD LED TV's with 1920x1080 pixels (True HD), have built-in
Freeview, currently they do not support the new HD Freeview standard
that will launch in the UK in 2010.
Touch screen monitors allow you to select options by touching
the screen. Touch replaces the need for a mouse. Useful in
public areas for transport and shopping information. Patients can
check in at hospital and medical surgeries using a touchscreen LCD
monitor. LCD touch screen. For

Multi-screen LCD monitor
display systems allow you to expand your view across multiple
monitors, multiple
mounts.
Waterproof television LCD monitors can be installed in most
wet areas, including over the bath, in the shower cabinet, sauna,
swimming pool area or above kitchen workshops. Tile
TV.
IP rated LCD monitors allow them to be used outdoors,
normally under some kind of shelter, for example, hotel and pub
patios. Please check the IP rating as these vary. IP (ingress
protection) have two digits.
The first is the degree of protection against dust or objects, for
example, 5 is protection from the amount of dust that would operate
with the equipment; 6 is dust right.
The second digit is protection against moisture, for example, 5 is
projection from water projected from a nozzle; 6 is protection
against heavy seas or powerful jets of water; 7 is protection
against immersion.
Therefore, as an example, a screen with IP65 rating gives protection
against dust and water from a nozzle, whilst IP66 rating gives
protection against dust and heavy seas or powerful jets of water.

Security and surveillance LCD monitors are designed specially
to show images from CCTV. LCD
monitors are an alternative to traditional CRT CCTV
monitors.Plasma screens and plasma
displays use a different technology and currently range
from 42 to 84 inches and come in both normal (4:3 ratio) and
wide-screen formats (16:9 ratio). They can be used for
computer and video input and you can switch between the two for
presentations. Plasma info

Interactive whiteboards are
used with a computer and projector to create up to a 100 inch touch
screen display. More information on whiteboards,
