PAL LCD TVs

New is gold

If you’re in the market for a new TV, and if your budget allows, you have several choices today. One aspect may be saying goodbye to your now outdated and bulky CRT television. Another aspect may be that you want to enjoy the sharpness of the television, color combination, flat stance which is prominent in new televisions. It may also be the case that you are a technical person and want to enjoy the new visual wonders of high-end television in the modern age. Even you might be a sports lover who wants to enjoy the real fun of the World Cup Finals or the US Open Tennis Championship at Flushing Meadows. As technologies advance from time to time, your visions get better and better.

The aspects to consider when going for a new TV

A number of things that may need to be taken care of before you really say goodbye to your old one for a new one. Some of the aspects are:

1. Is it really worth going for the new television at the expense of the old one?

2. Does your budget allow for the latest and greatest in TV sets?

3. If you really go for the new, which TV should you choose?

The choice

When the question of buying a new television with all modern technologies is concerned, perhaps the best option would be to have an LCD television with PAL broadcast standard compatibility. It will obviously be better than an NSTC or SECAM compatible TV in the sense that PAL happens to be the most widely accepted broadcast standard, not only in Asia and Europe, but now in many parts of America as well.

About PAL

As already mentioned, PAL or Phase-Alternating Line is the broadcast standard widely accepted in most of the world. While Asia and Europe are fully covered with television sets with PAL broadcast standard compatibility, France faithfully follows the earliest SECAM standard. A section of America that previously preferred the NTSC standard now prefers PAL.

The system

PAL is an analog broadcast standard. It uses in all 625 changing lines. PAL operates in most countries where it is used on the 50 Hz frequency. The system encodes colors and produces better and sharper image qualities with increasing color luminance.

Why PAL

Almost all countries in Asia and Europe with the exception of France use the PAL broadcast standard today. However, the US and Japan 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. It is type B, G, H, D, I, K, N and M. The countries that mostly use PAL 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 solve a large part of these problems as there are several beautifully modeled TVs on the market that are configured in a way to be compatible with almost all broadcast standards such as PAL, NTSC or SECAM. Another advantage of these LCD TVs is that they are thinner and take up less space and also weigh less to be portable enough for the general convenience of the user. Being portable and lightweight, they can be carried wherever you travel more – so as they are compatible with all standards, you will be able to watch local programs in the new place with your own TV without requiring additional devices, technical changes or additions.

Advantages of LCD

A multi-system television may not be your ultimate choice due to various reasons like cost, specifications, design, etc. But you may always prefer Liquid Crystal Display (LCD) screens as they provide you with a number of advantages that are not available with conventional television sets. An LCD television uses liquid crystal technology for visual output. Usually 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 ghosting during action viewing. it was also necessary for viewers to either remain in line with the screen or have a slight angle. Today, modern technological inventions have taken care of this problem and LCD TVs with plasma screens now dominate the consumer electronic media market.

The entrance to the giant LCD TVs

A few years back, in October 2004, LCD TVs with a 40-45 inch screen appeared on the market. There was fierce competition among the leading companies such as Sharp, LG, Samsung and larger TV screens appeared on the market one after the other. Sharp’s 65 inch TV was followed by Samsung’s 82 inch TV.

The advantage of LCD compared to conventional TVs

LCD televisions are among the latest high-definition televisions that have rich picture quality and color combinations. Most of the LCD TVs also offer high contrast features. In brightly lit environments, the images are quite attractive and captivating. Since there is a built-in backlight in the screens, the brightness is just as it should be. Cathode Ray Tube (CRT) televisions of old were huge and bulky. In contrast, LCD screens are flat, lighter and take up very little space, being slimmer and trimmer. They can even blend into the natural background of the room or can even be hung on the wall, which was not possible with the conventional TVs.

LCD technology

Liquid Crystal Technology uses millions of crystals encased in a liquid base. When electricity passes through, the heat-sensitive crystals enclosed between two panes of glass allow the light to pass through. They are further manipulated to varying degrees. This in turn results in the production of pixels in a wide range of colors. When electrical 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 placed on a polarized glass substrate. Specific rows are turned on to allow the electrical charges to reach their target columns. Therefore, only one particular pixel capacitor is charged at a time. The process is repeated and micro-increments are affected. The final result is over 256 shades or levels of brightness for each color pixel.

The history of LCD TV

LCD TVs date back to the year 1888, when Austrian scientist Friedrich Reinitzer discovered the properties of liquid crystallization. But it took another 80 years, and in 1968 the first LCD screen was developed. This was done by RCA. Originally, an LCD screen happened to be less than twenty inches in size, but later larger LCD screens appeared on the market. Certain models go up to 50 inch size. Side by side, with the development of technology, prices also started to become competitive for the benefit of consumers in general. Today, a customer has several choices in front of him in terms of cost, design, model, pattern, etc. One of the best features of an LCD TV is that the screen has a lifespan of 25 years or sixty thousand hours of normal use. These properties are the result of the light source in an LCD being replaceable. However, there is no burn-in in the case of LCD TVs as they do not use phosphor dots and use color filters in the tabular pattern. While the first LCD TV proved not to be good enough due to ghosting in action broadcasts, today’s LCD is a real joy to watch. Due to the inverse pull-down correction, the image quality is very good. Distortions in transmission or in data packets during transport are now a rare event.

The top names

LCD TVs of all sizes and brands are now available in the market. The biggest name in the fray are Sharp, Sony, Panasonic, JVC, Hitachi, LG, Phillips etc. Generic LCD TVs are also available online. LCD TV prices can be as low as $200 and as high as $1,000. But the price variation depends on the brand, quality, etc. LCD TVs come as flat screens, rear projections, etc. Today, they also come in portable models and even wireless models.

Points to consider before buying new LCD televisions

Last but not least, there are a few points to keep in mind when shopping for a new LCD TV. You can take into account:

o The place where you will place your TV. The LCD TV is slim and compact and takes up less space. It is also a decorative device.

o The LCD TV can be placed on wall or ceiling brackets or even table stands, as required by the interior of the room.

o Choose carefully the place to buy your new LCD TV. While a brick and mortar store in the city may be a better place in terms of quality and price and visibility, the Internet allows you to choose from a wide variety of brand names. While prices vary from provider to provider both in a brick and mortar store as well as on the Internet, be well informed about the provider, terms of sale and delivery, and background check all aspects of the transaction.

o Get your TV properly insured against damage and theft.

Conclusion

LCD TVs with PAL compatibility are not only slim and decorative, they offer a great advantage of reduced power consumption. They use 50% less power compared to traditional CRT TVs. So while you enjoy the grandeur and abundance of the larger screen, you also experience the benefit of saving on your electricity bill. Since there’s no problem with burning out, you and your family can watch all your favorite shows, including DVD movies. An uninterrupted visual bonanza.
