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.
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.
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 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.
