| Tennis Championship at Flushing Meadows. As the | | | | like Sharp, LG, Samsung and larger screen TVs |
| technologies advance from time to time, your | | | | appeared in the market one after another. Sharp's |
| visions get better and better.The aspects to be | | | | 65 inch screen TV was followed by Samsung's 82 |

| things which might be required to be taken care | | | | TVsLCD TVs are among those latest |
| of before you really bid farewell to your old for a | | | | high-definition televisions that have rich-in-picture |
| new one. Some of the aspects are: - | | | | quality and colour combinations. Most of the LCD |
| 1. Is it really worth going for the new television | | | | TVs offer high contrasting capabilities too. In |
| set at the expense of the old one? | | | | bright light environment the images are quite |
| 2. Does your budget permit having the latest and | | | | attracting and captivating. Since back light is in built |
| the best of the TV sets? | | | | in the monitors, the brightness is just as it should |
| 3. If you really go for the new one which TV | | | | be. Old day Cathode Ray Tube (CRT) televisions |
| you should opt for? | | | | were huge and bulky. In contrast the LCD |
| The choiceWhen the question of buying a new | | | | monitors are flat, lighter and takes very little |
| television set with all modern technologies is | | | | space, being slimmer and trimmer. They may |
| concerned, perhaps the best option would be to | | | | even blend in the natural background of the room |
| have a LCD television, having PAL broadcasting | | | | or can even be hung on the wall, which was not |
| standard compatibility. It will be obviously better | | | | possible with the conventional TVs.The LCD |
| than a NSTC or a SECAM broadcasting compatible | | | | technologyThe Liquid Crystal Technology uses |
| television set in the sense that PAL happens to | | | | millions of crystals enclosed in a liquid base. With |
| be the most widely accepted broadcasting | | | | electricity passing through, the heat-sensitive |
| standard, not only in Asia and Europe but now in | | | | crystals that are enclosed between two panes of |
| many parts of America too.About PALAs already | | | | glass allow light to pass through. They are further |
| stated, PAL or Phase-Alternating Line, is the | | | | manipulated in varying degrees. This on turn |
| broadcasting standard that is widely accepted in | | | | results in production of pixels of a broad range of |
| most part of the world. While Asia and Europe is | | | | colours. When electric current interacts with the |
| fully covered with TV sets having PAL | | | | liquid crystals, it blocks the light. The result is a set |
| broadcasting standard compatibility, France | | | | of gray and transparent crystals. The widely used |
| faithfully follows the earliest SECAM standard. A | | | | crystal type is the twisted nematic or TN liquid |
| part of America earlier preferring the NTSC | | | | crystal. In this case the tiny transistors are laid on |
| standard is now preferring PAL.The SystemPAL is | | | | a polarized glass substrate. Specific rows are |
| an analogue broadcast standard. It uses in all 625 | | | | turned on to allow the electric charges to reach |
| alternating lines. PAL operates in most of the | | | | their target columns. Hence at one time only a |
| countries where it is used on the 50 Hz | | | | particular pixel capacitor is charged. The process is |
| frequency. The system encodes colours and | | | | repeated and micro-increments are affected. The |
| produces better and sharper picture qualities with | | | | final result is over 256 shades or levels of |
| magnifying colour luminance.Why PALNearly all the | | | | brightness for each colour pixel.History of LCD |
| countries in Asia and Europe with the exception of | | | | TVLCD TVs date back to the year 1888 when |
| France, are using the PAL broadcasting standard | | | | the Austrian scientist Friedrich Reinitzer invented |
| today. United States and Japan however, still have | | | | the properties of liquid crystallization. But it took |
| a majority of NTSC standards. PAL appeared on | | | | another 80 years, and in 1968 the first LCD was |
| the commercial arena way back in the year 1967 | | | | developed. This was done by RCA. Originally, a |
| and has as many as eight different types in use. | | | | LCD monitor happened to be less than twenty |
| These are types B, G, H, D, I, K, N and M. The | | | | inches of size, but later larger LCD monitors |
| countries that use PAL mostly are China, India, | | | | appeared in the market. Certain models go up to |
| Indonesia, Israel, Laos, Nepal, Pakistan, Thailand, | | | | 50 inches size. Side by side, with the development |
| Lebanon, Iraq, Iran, United Kingdom, some | | | | of technology, the prices also started to become |
| European countries, some countries in South | | | | competitive favouring the consumers in general. |
| America and also in Africa.What if the LCD PAL | | | | Today, a customer has got multiple choices |
| compatible TV does not work with other | | | | available before him in terms of cost, design, |
| standardsTechnological development and new | | | | model, pattern etc. One of the best |
| inventions have been able to sort out major part | | | | characteristics of a LCD TV is that the monitor |
| of these problems since there are numerous | | | | has a life of 25 years or sixty thousand hours of |
| beautifully modeled TVs in the market that are | | | | normal use. These capabilities are the result of the |
| configured in a way to be compatible with almost | | | | fact that in a LCD, the light source can be |
| all the broadcasting standards like PAL, NTSC or | | | | replaced. However, there is no burning-in in case |
| SECAM. Another advantage of these LCD TVs | | | | of LCD TVs since they do not use phosphor dots |
| are, that, they are thinner and take less space | | | | and use colour filters in the tabular pattern. While |
| and also weigh quite less to be portable enough | | | | the first LCD TV did not prove to be good |
| for general convenience of the user. Since they | | | | enough due to ghost images in action broadcasts, |
| are portable and light weighted, they can be | | | | today LCD is a real pleasure to watch. Due to the |
| carried anywhere you travel more-so since they | | | | reverse pull down correction, the quality of picture |
| are compatible to all standards, you will be able to | | | | is very good. Distortions in transmission or in data |
