Plasma vs LCD TVs
For a layman, there seems to be no difference between a plasma and LCD TV. Both provide high-resolution, high-contrast images and both are flat, sleek and can be mounted on a wall. The difference lies in the technology that drives them.
Plasma TVs work with inert gases like xenon or neon, which are excited by electric pulses from specialized cells called pixels. This makes the gases glow. These glowing gases, in turn, produce the correct blend of red, blue and green light on the pixels.
The pixels are illuminated by a fluorescent light bulb, which is driven by semiconductor software on the motherboard.
LCDs are actually thin film transistors (TFT), which contain liquid filled crystals between two plates of glass. LCDs work by blocking out unwanted light. When the signal hits the TFTs, they contort to a required angle, thus allowing only the requisite amount of light to pass through. A lamp behind the screen or a thin LCD bulb provides illumination to the TFT.
LCD TVs and plasma TVs have their individual strengths and weaknesses.
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.
Earlier LCD TVs were priced much higher than plasma TVs. But due to stiff competition, their prices have come down drastically.
According to their current standing, LCD TVs cost only marginally more than plasma TVs. .

A plasma TV may very well be the next step in your home entertainment future and the potential sources for the purchase of a plasma TV have never been better. Because a handful of retailers have jumped on the plasma TV bandwagon and started offering these televisions as part of their home electronics line, the cost of a plasma TV has never been lower. The fact that the technology has become well-established has also helped lower the cost of the plasma TV. So where do you go to find great deals on plasma TV sets?
Any retailer or wholesaler that offers a good array of home electronics likely has plasma TV sets in stock or has a source for them. For many people, purchasing from a local retailer is literally the only option they'll consider because they want to check out the set "in person." While the cost has started dropping, a plasma TV still represents a major investment among your home entertainment components and you may be playing it safe to shop where you can actually...

You've finally made up your mind to buy a plasma TV. You dream of watching your favorite television shows in full stereo, with sharp, crisp picture resolution. But how do you go about finding your dream TV? Here are a few tips that will help you get started.The first thing that you should do is to decide on the size of the television monitor you want. Generally speaking, plasma TVs begin at around 32" and go as large as 63". The most common screen sizes are usually 32", 42", 50" and 61".
So, measure the area where you want to place your TV to get an idea of which size would be most practical for you. It's important to remember that most plasma TVs have detachable speakers, so you will need to allow for a few extra inches on either side of where the screen will be.You may well have the option to buy extra slim speakers, which attach directly to the monitor, if you don't want to use your own or an additional sound system, with surround sound. It is important to check that the model...
