Why You Should Buy An Lcd Tv.
If you've thought about purchasing an LCD television
, you probably have quite a few questions. Factors to consider include available screen sizes, longevity of the product, clarity of the image, and whether the television will be compatible with existing add-ons such as a VCR. Let's take a look at the LCD television.
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.
Although LCD and plasma TV's look much alike, their technology is entirely different. Plasma televisions are comprised of individual cells. Each of these cells is filled with neon-xenon gas. When electricity is passed through the cells, it strikes blue, red and green phosphors to react. Each group of these phosphors is a pixel, or picture element; one tiny part of the whole image.
Until recently, LCD TV's 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 color quality, will not look as good on an LCD TV as it did on a smaller analog television.
When buying an LCD television, decide where you are going to place it, and how you are going to use it. Some like to integrate it with their home theatre system for a truly surround-sound experience. If this is your plan, ensure that you have the correct cables, bracket or cabinet for displaying your new equipment, as well as providing surge protection for your LCD TV.
LCD panels are thin and take up little space in your home, as well as using less power than a conventional or plasma TV. You can expect long life, in excess of 60,000 viewing hours, and a brilliant, clear image. The LCD television is definitely a wise purchase.
