LCD flat screen TVs provide a superior image compared to traditional TV - and that may come in more attractive styles to boot. A flat screen LCD TV can be mounted on a wall under a cabinet, on the ceiling ... or you can sit on a bench or on top of furniture. LCD TVs are versatile, flexible and provide better entertainment experience ... But how do they work?
LCD flat screen TVs, and LCD technology itself is based on the properties of polarized light. LCD televisions consist of two, arranged perpendicularly polarized glass "stuck" for a solution filled liquid crystal polymer. When exposed to electric current, the crystals untwist to varying degrees, allowing specific amounts and colors of light to pass though them. Flat Screen Televisions LCD are, in effect, projection televisions that rely on a very bright light as its light source, so you're considered a "passive" display.
So how to choose the right flat panel LCD TV for you? You should consider at least the following factors when purchasing a flat screen LCD TV.
1. Find an HDMI input. This port keeps the signal all-digital, avoiding degradation that can occur that the signal passes through other components (like your cable box). HMDI carries high definition audio and video. Some satellite receivers and DVD players also connect through this port.
2. Match the LCD TV size for the size of the room where placed. Because LCD TVs have higher resolution than conventional TVs, you can sit closer than they normally would, so you can see a larger screen with ease. (Consider a 42-inch screen can overwhelm a small room, however.)
3. Decide whether you want the picture-in-picture. The picture in picture function allows you to view two video sources at once, with one that appears as a small window on the screen. If you want picture-in-picture on the LCD flat screen television, be aware that a single tuner picture-in-picture allows you to watch TV in a window and another source (like a DVD) in the second window. A LCD flat screen TV with two tuners lets you watch two television sources at once.
4. Need HDTV? A flat panel LCD TV with EDTV is cheaper, but can not display high definition signals. The price difference between the smaller LCD flat screen HD-ready and ED-LCD is quite low, so it is better to buy a HD-ready set. In fact, most experts say there is little reason to buy an HD LCD TV. These LCD TVs with lower resolution will not be able to accept high definition signals, so that the image does not look better than regular analog TV. Pequeñas y HD-ready TV LCD se puede encontrar por $ 500 o menos, que es lo suficientemente barato que en realidad no es mucho para "salvar" a un no-HD LCD TV.
5. Check if the TV comes with a hardware support and installation. Most LCD flat screen televisions come with a support base table, but the wall mount hardware costs an additional $ 100 to $ 200.
6. Look in the policy of the manufacturer's warranty before you buy online. Some manufacturers have strict policies regarding authorized dealers. If you buy a Sharp LCD television, for example, an unauthorized distributor, Sharp can not offer warranty coverage. (However, the seller can offer a replacement warranty that sufficiently covers you.) The price difference between an authorized distributor of Sharp and a discount store can sometimes be hundreds of dollars, so make sure you are comfortable with the risk of not having a guarantee, or be sure to ask your dealer for information about warranty conditions for flat panel LCD TV you're considering.
7. Finally, learn about LCD TVs. There are things much more to learn about the LCD TVs above points. Get educated on how to buy an LCD TV.
