Plasma vs LCD vs LED I've got a confession to make. I love television. And I love big screen TVs. Especially the new flat panel models. Before you know it, everyone will forgo their traditional CRT television sets and own a LED LCD flat screen TV. This idea really isn't as strange as it sounds. LCD flat screen TVs are becoming more and more popular, and with good reason.

But, you may be wondering, what exactly is a flat screen TV? Flat screen TVs have displays only a few inches thick. This makes them attractive and extremely convenient. You can now hang this kind of TV on the wall, or place the set in thin areas. A LCD flat screen TV can save a lot of room in your home and look stylish doing so. However, there are a few things one should know before he or she buys a LCD flat screen TV.

Plasma vs LCD

Plasma TVs heavily rely on the fluorescent light bulb. A plasma flat screen display consists of cells. Inside each cell are two glass panels separated by a narrow gap. These gaps are injected with neon-xenon gas and sealed in plasma form. The gas is electrically charged when the plasma TV set is in use. The gas strikes red, green, and blue phosphors. This is what creates the TV image. Because plasma TVs use the burning of phosphors to produce an image, they can suffer from the same drawbacks of traditional TVs, such as high heat generation and screen burn-in. Also, plasma TVs tend to be very expensive.

LED vs LCD What to Know About a LED LCD Flat Screen TV A LED LCD flat screen TV consists of primarily two transparent, glass-like materials, which are polarized, and "glued" together. One of the plates is coated with a polymer that holds the individual liquid crystals. Electric current is then passed through individual crystals. This allow the crystals to pass or block light to create images. Unlike plasma TVs, an external light source is needed.

LED LCD flat screen TV screens range from 15-inch models that are primarily used as computer monitors or secondary TVs, to 100-inch wide screen TVs. (Although Sharp makes a magnificent 70-inch flat screen TV in its Aquos brand lineup.)

How To Buy A LED LCD TV With High Definition

If this doesn't get you excited, then nothing will. LED LCD TVs have become all the rage and there is nothing better than a big screen TV. And when you couple LED LCD TV with HD TV, look out. An amazing physical display combined with a fantastic output. This is what is happening in LED LCD TV technology today.

If you are like most people looking to replace your TV, you’ve probably been paying close attention to High Definition Television sets (HD-TV). Unlike the previous generation of TV, which used analog signals to transmit information, HD-TVs use digital signals to transmit a signal and receive and display information directly on the television set. The HD-TVs also use a High-Resolution digital television set and Dolby Digital surround sound. The combination of the two creates incredible pictures and sounds – the best available on the market to date. HD-TV television offers viewers a level of detail they haven't seen before: including a resolution about five times higher than that of analog TV.

The main thing to remember when you are shopping for HD-TV set is that just because a television is “digital” it does not mean it is necessarily “HD-TV compatible”. There are two levels below the HD level (standard definition TV and enhanced definition TV), both of which are vastly better than analog televisions but still of considerably lower quality than an LED LCD TV- HD-TV set. Since the FCC has mandated that all television sets eventually switch from analog to digital, you should know the differences between the different types of digital TVs.

Here are some tips. When looking to purchase an HD-TV, remember to compare the difference in picture resolution, audio features, and pixels. HD-TV requires a minimum of 720 horizontal scanning lines (enhanced definition TV, while considerably higher than standard definition TV, only features a minimum of 480 scanning lines) and the resolution on an HD-TV is 1920 x 1080 compared to enhanced definition TV, which only has a resolution of 1280 x 780.

When you experience a HD-TV image and then compare it to other TVs' technology on the market, the difference will be clear. With “HD” everything looks and sounds far more realistic than on any other type of system. We think that once you see a big screen LED LCD TV with HD-TV, the choice will be clear.

This is just the tip of the iceberg when looking for a HD LCD TV. In fact, many of the most important tips haven't been mentioned here. Learn about LED LCD TVs before making a purchase. LCD TV Deals
