subject: An Overview Of Lcd Tvs [print this page] If youve 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. Lets take a look at the LCD television.
Most consumers are aware of LCD technology from watches, cell phones, and video camera screens, but may not know what it is. Simply the screen is two panels of transparent matter, which have been cemented together. A polymer material containing the liquid crystals is applied to one of these layers. When electricity is connected to these crystals, they will either allow the light through or become opaque. It is this action which forms the images we see.
With their thin panels and similar shapes, many consumers assume that plasma TVs are the same as LCD. In reality, their technology is quite different. Unlike the LLCDs, plasma screens are made up of individual cells which have been filled with a gas. Electrical current running through the cells causes a reaction. Green, blue and red phosphors react, forming pixels, which we see as the complete 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.
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.
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.
An LCD television is a wise choice. The LCD panels are quite thin, and take up little space. They use less power than a conventional or a plasma TV. In addition they have a bright, clear image, and a long-life expectancy of 60,000 hours or more.
