The Pros and Cons Of LCD TVs
Many consumers are asking themselves if buying an LCD television is a good decision. They have questions about the clarity of the picture, screen sizes, cost, and how long it will last. They want to know if it will work with the equipment they already own. Lets look at some of the facts.
LCD (Liquid Crystal Display) is familiar to anyone who already owns a digital camera or mobile phone, but most people don't understand how it works. An LCD screen is comprised of two panels of a clear material, which are glued, or bonded, together. A polymer compound, which contains the liquid crystals, is layered onto one of the panels. When an electrical current is applied to the panel, the crystals either let the light though, or turn dark, thus creating the image.
The difference between LCD TVs and plasma TVs is not readily apparent. They look quite similar, but use entirely different technology. A plasma TV is made up of cells, which have been injected with a gas called neon-xenon . When electricity is applied to the cell, red, green and blue phosphors are struck. Each of these is called a pixel, and together they comprise the picture.
For some time after the introduction of LCD television, the plasma TVs still cornered the market in large-screen televisions. Although the smaller screen televisions were popular, the LCD technology made the large screens more expensive. The technology has been refined to the point where the large-screen LCD TVs are now comparably priced, and practical for the everyday shopper.
Since LCD TVs are so similar to the LCD computer monitor, buyers often wonder if they can be integrated with a PC and used as a computer monitor. Most of the LCD televisions do have the VGA input connections that will allow this integration. Gamers, especially, enjoy using the large screens with their computers to enhance their game-playing.
Many consumers desire to keep their old VCRs even when purchasing a new TV. These VCRs will integrate with the new TV, thanks to the standard connections, however there is one issue to keep in mind. The resolution on a VHS tape is much lower than that on the TV, which will result in poorer colour quality, as well as a grainier picture than the consumer has seen on their old, analogue television.
If you decide to purchase an LCD TV, choose the right place in your home for it before hand. That way, you can purchase the correct stand or hanging bracket at the same time. LCD TVs have internal speakers, but you can integrate your LCD television with your home theater system. Be sure that you have the correct cables, and provide power surge protection for your new television.
LCD TVs use less power, and emit less heat, than a conventional or plasma television. They last a long time, more than 60,000 hours of viewing time can be expected, and give you a vivid image. In addition, their slim design means they can be displayed just about anywhere. Purchasing an LCD TV is a shrewd decision.
