Liquid crystal display (LCD) technology may sound exotic, but in reality
we use it every day. LCD technology is utilized in stereos, computer
monitors, microwave ovens, digital clocks and calculators. Today, the
technology is also being used in high-tech flat screen TV sets and video
monitors that produce incredibly clear images.

LCD screens function by obstructing light. Within the screen, the ligquid
crystals are contained between two sections of polarized glass. The
crystals control the brightness of light as it’s transmitted through the
glass. An electrical charge is applied, and the crystals react to it,
rotating to allow the light to pass through the sections of glass. The
LCD display is made up of pixels and is illuminated by a florescent bulb
that sends white light through the glass panes. Each pixel is split into
red, green and blue sections that work together to produce a color image.
One pixel can create about 16 million colors.

LCD televisions offer plenty of benefits to viewers. They offer superior
brightness and contrast capability – far better than anything offered by
traditional cathode ray TV sets. Flat screen LCD sets also feature a 160
degree viewing angle, so that watchers will see everything from just
about any location in the room. Because the contrast quality is so good,
viewers don’t have to worry about turning off all the lights in the room
to get a good picture. Lamps don’t produce a glare on an LCD flatscreen
set.

Another bonus with an LCD set is that most models come equipped with
tuners and speakers. All you have to do is plug the set in, and it’s
ready to go. The tuners and speakers are built in, which means no extra
components like set-top boxes or receivers are required. This makes the
LCD set perfect for homes that don’t have much space to spare for a big
TV that requires extraneous equipment.

LCD sets are equipped to display high definition television as well as
standard television. LCD sets can also serve as computer monitors and
all-around video monitors. They can handle any kind of video format, and
most come equipped with inputs for S-video, component video, and
composite video. Most LCDs offer about 60,000 hours (or about twenty
years) of viewing, making them a good investment. They last longer than
plasma sets. The bulb is a critical factor in the LCD set, as it’s
responsible for picture and color quality. With some sets, the bulb can
easily be replaced. Other sets have bulbs that are built in to the LCD
system, making matters more complicated when it’s time to replace the
light source. Before investing in one of these sets, check into brands
and model types. It pays to do a little research prior to buying.
