Liquid crystal display
is a type of display widely used in computer monitors, television, watches,
aircraft cockpit displays, signage and many other electronic devices. Samsung LCD TV are
usually more compact, lightweight, portable and efficient than cathode ray tube.
They utilize two sheets of polarizing filters with a liquid crystal between
them. An electric current passed through causes the crystals to align so that
light cannot pass through them. Images in color or monochrome are produced by
electronically modulated device that controls currents. The sandwiching liquid
crystals are between two finely grooved surfaces, where the grooves on one
surface are perpendicular to the grooves on the other. The crystals are forced
into a twisted structure, which also twists the light passing through by 90 degrees.
No voltage is applied; polarized light can pass through the lower analyzer.
The liquid crystals are
very sensitive to temperature and are often used to make thermometers. A fair
amount of heat and high temperature difference may also spoil the crystals and
cause leakage. It is commonly used to display characters and graphic images
when connected a host system. A Samsung LCD TV module consists of a TFT panel,
driving-circuit unit, and backlight system and assembly unit. The color filter
contains the black matrix and resin film containing three primary color - red,
green, and blue - dyes or pigments. The two glass substrates are assembled with
a sealant, the gap between them is maintained by spacers, and LC material is
injected into the gap between the substrates.

LCD TV where designed
to be computer monitors. It is advisable that you buy an Samsung LCD TV with a built in
tuner if you want your LCD monitor to be used as a TV and a computer
monitor.LCD televisions and monitors consume less power than other display
types, are lightweight and produce a bright picture. The latest in LCD
technology has increased the power savings and a slimmer profile. Samsung LCD TV have poor contrast ratios. This is due to backlighting shining
through the panel. Color can distort when looking at an LCD from an angle
especially with older LCD monitors. Because of the backlighting, pixels on an
LCD are unable to generate light independent of the rest of the picture. Color
accuracy suffers on Samsung LCD TV due to this fact. Color saturation is
reduced at low intensity levels due to a poor black-level. Images are
satisfactory but not accurate due to problems with black-level, gray-scale and
Gamma.
Each pixel on a plasma
television is able to control brightness and color individually. This increases
contrast ratio and color accuracy. Viewing angles on plasma televisions are
outstanding, and they are much cheaper than LCDs. The Samsung LCD TV is good when watching
at the very center, but the more you get farther from the center though you can
still look at the images at the screen you cannot fully watch the images very
well. The refresh rate is slower. LCD TVs have refresh rates from 60 Hz to 240
Hz, whereas plasma TVs refresh anywhere from 400-600 Hz. It makes a difference
when watching sports on HD channels and playing HD games like PS3 and X-BOX
360.The viewing angle for most Samsung LCD TV is very narrow. Slow response times and
scan rate conversion result in severe motion artifacts and image degradation
for moving or rapidly changing images.
