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.
Exactly what is an LCD TV? LCD stands for Liquid Crystal Display. This is the same technology that has been used for some time for camera screens and cell phones. It is constructed of two panels of glass-like material, which are bonded together. One layer is coated with a special polymer which contains the liquid crystals. An electrical current is run through the crystals which can turn dark or allow light to pass through, thus creating the picture.
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.
Until recently, LCD TVs have been more popular in the smaller sized televisions. This is partly because technology caused the prices of the larger screens to be much more expensive than the smaller sets. However, technology is constantly improving and now there is less of a price difference, making the large-screen sets more available to the average consumer.
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.
You may have older auxiliary devices such as a VCR, and wonder if they are compatible with the LCD televisions. They will work together, since most LCD televisions have standard AV connections. However, a VHS tape, with its lower resolution and poorer colour quality, will not look as good on an LCD TV as it did on a smaller 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.
