LCD Tv – How To Maintain Your LCD Screens

“LCD” is a recently conceived display technology which offers clear images with the support of crystals.

These crystals will be sandwiched between two thin layers and when the power hits on these crystals, they begin to display pictures on the screen.

This new technology has been embedded with most of the televisions and laptops. It is your duty to preserve this technology by taking certain precautions like:

Always play your LCD television only at living room temperature. Therefore you can maintain your screen life for longer.

When you use your TV more than optimum humidity and temperature, you may lose your lifetime of the product. It should not go below 10 degree Celsius.

If so the brightness and the response time of the TV will be diminished automatically. Huge fluctuation in humidity and temperature will also make your product lose its lifetime.

Your television screen has to be free from dust and other liquid spots. Better to keep in a neat place. Dust may become a cause malfunctioning. When any liquid goes inside, it will surely cause corrosion.

It is essential to care of the screen, as it is made with fragile natured glass material. Keep your screen free from vibrations, shaking’s etc.

When it comes to choosing which kind of TV to buy, whether it’s LCD TV or Plasma TV, consumers always have a hard time deciding. That’s why we will break down everything in order to prove to consumers that an LCD TV is the much better choice over a Plasma TV.

LCD TV and Plasma TV both represent the fast advancing technology that is offering viewers the best in Television viewing. But it doesn’t mean that one would cease to try to choose between these two, the better option with regards to quality and money.

There are certain advantages for both LCD TV and Plasma TV but at a careful analysis it has been proven that the LCD TV offers more advantages compared to the strong points of Plasma TV. Here are some of the finer points that the LCD TV has proven to be the better choice. Study each carefully and hopefully it will help you a great deal in choosing what to buy and answer your question “Why one should choose an LCD TV over a Plasma TV?”

Plasma TV started out with a little advantage over the LCD TV, but with the newer models of LCD TV, it has since catch up and overtaken Plasma TV with regards to picture quality and better contrast. The new LCD TVs now offers a much better color display than Plasma TVs and to add on to that, LCD TVs holds a sizable advantage with its resolution and therefore will offer a greater viewing experience compared to Plasma TV.

When it comes to using LCD TV for game consoles, LCD TVs hold the edge over Plasma TV by having a higher amount of panel resolution, the game images will look more lifelike and will result in a greatly detailed video gaming experience. Also, these advantages of the LCD will also make it possible for texts to appear more visible on screen than the ones in a Plasma TV.

But the biggest and most important advantages of LCD TV other than the picture quality and lifespan is the cost of LCD TVs compared to Plasma TVs. Naturally, one would expect a much better quality and lifespan for something more expensive but that is not the case with the LCD TV and Plasma TVLCD TV even though it relatively costs a lot cheaper than Plasma TV, it also offers the best picture quality and possess the longer life span. With all these in mind, it’s obvious that LCD TV is the best choice over its Plasma counterpart.


HDTV – The High Resolution Television

The expansion of hdtv is High-definition television. The hdtv means television signals broadcast with a higher resolution than traditional formats like NTSC, SÉCAM, PAL. The hdtv is broadcasted digitally, except for early analog formats in Europe and Japan.

Historically, the term high-definition television was also used to refer to television standards developed in the 1930s to replace the early experimental systems, although, not so long afterwards, Philo T. Farnsworth, John Logie Baird and Vladimir Zworkin had each developed competing TV systems but resolution was not the issue that separated their substantially different technologies. It was patent interference lawsuits and deployment issues given the tumultuous financial climate of the late 20’s and 30’s. Most patents were expiring by the end of WW2 leaving the market wide open and no worldwide standard for television agreed upon. The world used analog PAL, NTSC, SECAM and other standards for over half a century.

The terms HD ready and HD compatible are being used around the industrial world for marketing purposes. They indicate that a TV or display is able to accept video over an HDMI connection, using a new connector design, the main purpose of which seems to be to ensure that digital video is only passed over an interface which, by agreement, incorporates copyright protection. Even HD-ready sets do not necessarily have enough pixels to display video to the 1080-line (1920×1080) or 720-line (1280×720) HD standards in full resolution without interpolation, and HD-compatible sets are often just standard-definition sets with an HDMI input. This is a confusing use of the terms HD and hdtv.

MPEG-2 is most commonly used as the compression codec for digital hdtv broadcasts. The hdtv is capable of “theater quality” audio because it uses the Dolby Digital (AC-3) format to support “5.1” surround sound.

Japan has the earliest working hdtv system still in use, with design efforts going back to 1979. Japan began broadcasting analog hdtv signals in the early 1990s using an interlaced resolution of 1035 lines (1035i). The Japanese MUSE (Multiple sub-nyquist sampling Encoding) system, developed by NHK Science and Technical Research Laboratories (STRL) in the 1980s, employed filtering tricks to reduce the original source signal to decrease bandwidth utilization.

Japan is forerunner of hdtv in the world. Japan terrestrial broadcast of HD via ISDB-T started in December 2003.

The hdtv transmission in Europe started in 2004. Euro1080 is the pioneer in hdtv transmission in Europe. Australia started HD broadcasting in January 2001.

CHUM Limited’s Citytv in Toronto was the first hdtv broadcaster in Canada and CBC (Canadian Broadcasting Corporation) officially launched hdtv programming on March 5, 2005.

Mexican television company Televisa experimented hdtv broadcasts in the early 1990s, in collaboration with Japan’s NHK.

The hdtv specifications are defined by the ATSC in the United States. An hdtv-compatible TV usually uses a 16:9 aspect ratio display with an integrated ATSC tuner. Lower resolution sources like regular DVDs may be upscaled to the native resolution of the TV.

The hdtv services were made available in the Republic of Korea in 2005 and Brazil is expected to go for it in 2006.

There are numerous online sources carrying volumes of info on plasma hdtv, lcd hdtv, hdtv antenna, hdtv receiver, dlp hdtv, hdtv cables, hdtv tuner etc. Scores of sites are offering hdtv reviews, hdtv articles and hdtv news that are very helpful for the potential customers to buy hdtv.
