several choices today. One aspect may be saying goodbye to your now outdated and
bulky CRT television. Another aspect may be that you desire to enjoy the
sharpness, colour combination, flat posture of the television that are prominent
in new TVs. It may also be a case that you are a technical person and want to
enjoy the new visual wonders of cutting edge TV of modern age. Even you may be a
sports lover wanting to enjoy the real fun of the World Cup Finals or US Open
Tennis Championship at Flushing Meadows. As the technologies advance from time
to time, your visions get better and better.
The aspects to be considered while going for a new TV
A number of things which might be required to be taken care of before you really
bid farewell to your old for a new one. Some of the aspects are: - 1. Is it
really worth going for the new television set at the expense of the old one? 2.
Does your budget permit having the latest and the best of the TV sets? 3. If you
really go for the new one which TV you should opt for? The choice
When the question of buying a new television set with all modern technologies is
concerned, perhaps the best option would be to have a LCD television, having PAL
broadcasting standard compatibility. It will be obviously better than a NSTC or
a SECAM broadcasting compatible television set in the sense that PAL happens to
be the most widely accepted broadcasting standard, not only in Asia and Europe
but now in many parts of America too.
As already stated, PAL or Phase-Alternating Line, is the broadcasting standard
that is widely accepted in most part of the world. While Asia and Europe is
fully covered with TV sets having PAL broadcasting standard compatibility,
France faithfully follows the earliest SECAM standard. A part of America earlier
preferring the NTSC standard is now preferring PAL.
PAL is an analogue broadcast standard. It uses in all 625 alternating lines. PAL
operates in most of the countries where it is used on the 50 Hz frequency. The
system encodes colours and produces better and sharper picture qualities with
magnifying colour luminance.
Nearly all the countries in Asia and Europe with the exception of France, are
using the PAL broadcasting standard today. United States and Japan however,
still have a majority of NTSC standards. PAL appeared on the commercial arena
way back in the year 1967 and has as many as eight different types in use. These
are types B, G, H, D, I, K, N and M. The countries that use PAL mostly are
China, India, Indonesia, Israel, Laos, Nepal, Pakistan, Thailand, Lebanon, Iraq,
Iran, United Kingdom, some European countries, some countries in South America
and also in Africa.
What if the LCD PAL compatible TV does not work with other standards
Technological development and new inventions have been able to sort out major
part of these problems since there are numerous beautifully modeled TVs in the
market that are configured in a way to be compatible with almost all the
broadcasting standards like PAL, NTSC or SECAM. Another advantage of these LCD
TVs are, that, they are thinner and take less space and also weigh quite less to
be portable enough for general convenience of the user. Since they are portable
and light weighted, they can be carried anywhere you travel more-so since they
are compatible to all standards, you will be able to see local programs at the
new place with your own TV without requiring additional devices, technical
modifications or add-ons.
Advantages of LCD
A multi-system Television set may not be your ultimate choice owing to various
reasons like the cost, specifications, design etc. But you may always prefer
monitors with Liquid Crystal Display (LCD) since they offer you a number of
advantages not available with conventional television sets. A television set
with LCD utilises the liquid crystal technology for visual output. Ordinarily
these devices use Thin Film Transistor (TFT) for its functions. In older days
when LCD TVs made its first appearance in the consumer market, it experienced
certain problems like the ghost images during action display. it was also
necessary for the viewers either to remain in straight line with the screen or
having a slight angle. Today, the modern technological inventions have taken
care of this problem and LCD TVs with Plasma displays are now dominating the
consumer market of electronic media.
The entry of the giant screen LCD TVs
A couple of years back, in October, 2004, LCD TVs with 40-45 inches screen
appeared in the market. There was a fierce competition among the leading
companies like Sharp, LG, Samsung and larger screen TVs appeared in the market
one after another. Sharp's 65 inch screen TV was followed by Samsung's 82 inch
Advantage of LCD over conventional TVs
LCD TVs are among those latest high-definition televisions that have
rich-in-picture quality and colour combinations. Most of the LCD TVs offer high
contrasting capabilities too. In bright light environment the images are quite
attracting and captivating. Since back light is in built in the monitors, the
brightness is just as it should be. Old day Cathode Ray Tube (CRT) televisions
were huge and bulky. In contrast the LCD monitors are flat, lighter and takes
very little space, being slimmer and trimmer. They may even blend in the natural
background of the room or can even be hung on the wall, which was not possible
with the conventional TVs.
The LCD technology
The Liquid Crystal Technology uses millions of crystals enclosed in a liquid
base. With electricity passing through, the heat-sensitive crystals that are
enclosed between two panes of glass allow light to pass through. They are
further manipulated in varying degrees. This on turn results in production of
pixels of a broad range of colours. When electric current interacts with the
liquid crystals, it blocks the light. The result is a set of gray and
transparent crystals. The widely used crystal type is the twisted nematic or TN
liquid crystal. In this case the tiny transistors are laid on a polarized glass
substrate. Specific rows are turned on to allow the electric charges to reach
their target columns. Hence at one time only a particular pixel capacitor is
charged. The process is repeated and micro-increments are affected. The final
result is over 256 shades or levels of brightness for each colour pixel.
History of LCD TV
LCD TVs date back to the year 1888 when the Austrian scientist Friedrich
Reinitzer invented the properties of liquid crystallization. But it took another
80 years, and in 1968 the first LCD was developed. This was done by RCA.
Originally, a LCD monitor happened to be less than twenty inches of size, but
later larger LCD monitors appeared in the market. Certain models go up to 50
inches size. Side by side, with the development of technology, the prices also
started to become competitive favouring the consumers in general. Today, a
customer has got multiple choices available before him in terms of cost, design,
model, pattern etc. One of the best characteristics of a LCD TV is that the
monitor has a life of 25 years or sixty thousand hours of normal use. These
capabilities are the result of the fact that in a LCD, the light source can be
replaced. However, there is no burning-in in case of LCD TVs since they do not
use phosphor dots and use colour filters in the tabular pattern. While the first
LCD TV did not prove to be good enough due to ghost images in action broadcasts,
today LCD is a real pleasure to watch. Due to the reverse pull down correction,
the quality of picture is very good. Distortions in transmission or in data
packets in transit, are now a rare happening.
The top names
LCD TVs of all sizes and brands are now available in the market. The biggest
name in the fray is Sharp, Sony, Panasonic, JVC, Hitachi, LG, Phillips etc.
Generic LCD TVs are also available on the net. The prices of LCD TV can be as
low as $200 and as high as $1,000. But the price fluctuation depends on the
brand, quality, etc. LCD TVs come in as flat panels, rear projections etc. Today
they are also available in portable models and even wireless models.
Points to ponder before buying new LCD Televisions
Last but not the least, there are a few points you should remember while going

store in the town may be a better place in terms of quality and price and
visibility, Internet provides the option to choose from a wide variety of
branded products. While prices vary from provider to provider both in a brick
and mortar store as well as on the Internet, you need to be well informed about
the provider, the terms and conditions of sales and delivery and background
check every aspect of the transaction.
- Have your TV properly insured against damages and theft. Conclusion
