What is LCD in the first place? It is a thin panel, which is capable of displaying high definition TV signals, cable or satellite, regular TV, and home videos. 

Because of the high resolution of best LCD televisions, text and graphics look especially sharp when viewed on them, so to buy lcd is the best solution for displaying movies, data, web-based content and videogames. You can invest in LCD TVs or computer monitors and use it in its full capacity for many years: something like 60,000 hours. That means with normal viewing habits of, say, 8 hours per day, the lifespan of LCD you buy is about 20 years! LCD TV is a flat screen monitor that utilizes the same basic Liquid Crystal Display technology that has been used for some time in cell phones, camcorder viewfinders, and computer monitors.

LCD panels are made of two layers of a glass-like material, which are polarized, and are glued together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Electric current is then passed through individual crystals, which allow the crystals to pass or block light to create images. Liquid crystals don’t produce their own light, so an external light source like a fluorescent bulb is needed for the image created by the flat screen monitor to be visible to the viewer. Unlike standard "CRT monitor" and "Plasma", there are no phosphors that light up, so lcd televisions are thin and require less power to operate. Because of the nature of LCD technology, there is no radiation emitted from the screen itself, unlike with picture-tube televisions. Also, since they don’t need a picture tube, LCD TV can be made very thin, allowing them to be mounted on a wall or placed on small stand on top of a table, desk, dresser, or cabinet.

Mostly the high definition (HD) models – have the very good picture quality most consumers want in the largest LCD televisions. Viewing angles are improved, and many new models display a better image from off-center than older models did. Prices continue to decrease. The widest lcd televisions have been very expensive in the past, costing more than comparably-sized plasma sets, but prices are forecast to drop by 25 to 30 percent in the near future. So now is the best time to buy LCD sets.
