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.
When LCD televisions first came on the market, the smaller screens were not only more widely available, but were more reasonably priced. The technology needed cause the large screen TV’s to be more costly. With advancement in the technology, the price differences have evened out, making the larger sized LCD television economically feasible.
Many consumers wonder if they can use their LCD TV as a computer monitor. Most of them can be, due to the fact that LCD TV’s are an outgrowth of the LCD computer monitor. The majority of TVs have the VGA input connections necessary to be integrated into a PC. Gamers like to integrate their PC and game systems in order to have a large screen to play their games on.
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.
