Plasma Vs LCD TV

Plasma Vs LCD TV does somewhat depend on your personal specifications and what you want out of your television. What you will use your TV for could determine which model you choose.

Liquid Crystal Display (LCD) creates images by streaming light through LCD glass panels. The three panels are typically red, green, and blue filters. These filters will permit or block light to pass through each pixel thereby creating the final image. LCD TVs have brighter colors and can easily substitute for computer monitors. Most LCD TVs are less than 32". LCD TVs come in both HDTV capable and non-capable.

Plasma TVs offer more screen real estate. Plasma TVs are cheaper per square inch and have better black levels makes them ideal for people looking for a big-screen home-theater. Plasma TVs are not available below 37" screen size. Plasma TVs are either enhanced definition (EDTV) or high definition (HDTV). EDTV are cheaper and can display HDTV format but at lower quality.

Plasma TVs show better contrasts. Contrast means the ratio between the blackest black and the whitest white. A plasma TV can produce contrasts of even 3000 to 1, which is very high by LCD standards. LCD TVs can provide contrasts up to 900 to 1. However, in LCD technology, even a low contrast ratio can produce much better images.

Plasma TVs produce colors by addition of red, blue and green while LCD TVs produce colors by blocking unwanted light from the spectrum. Hence, plasma TVs produce colors by additive principle, while LCD TVs do the same by subtractive principle. That's why plasma TVs are much better at producing colors than LCD TVs.

Plasma TVs also have wide viewing angles, as much as 160 degrees. Since LCD TVs produce images by an LCD lamp behind the screen, viewing angles aren't wide. LCD TVs produce differently colored images when viewed at higher horizontal angles.

Though plasma technology wins over LCD technology in color, contrast and brightness, LCD wins hands down when it comes to the functionality. LCD TVs have greater longevity. Most LCD TVs can last up to twice the lifetime of a plasma TV. LCD TVs are also better suited to usage at higher altitudes or while traveling, because LCD technology does not use any gases, and is not subjected to air pressure.

LCD TVs are also energy efficient, as they require less voltage. This helps in reducing electricity bills.

Some plasma and LCD TV's have digital built in but with some you will need a digital box to receive channels only available through digital. Some digital boxes can also offer a lot of benefits like picture in picture and the ability to record several channels at once. To find out more about digital boxes visit www.beston-tv.com
