A Plasma TV vs LCD TV: Which one will you prefer

Plasma TV and LCD TV each have their own applications and use with both advantages and disadvantages and the decision to buy which one will depend on your needs. Both plasma and LCD technology are the latest technology available in home
entertainment giving us clear picture and you would surely find pleasure in watching them. Apart from this super fine quality, plasma tv and lcd tv are less bulky than the traditional cathode ray tube televisions and offer better resolution and high quality pictures together with great sound which is possible due to the advacement of technology. People get confuse when they go to the market to bring home television. Since the price for the plasma tv and the lcd tv are almost the same, it becomes difficult to determine which is the better one. The answer depends on what you plan to do with it like do you want to watch movies or want ot use for photography or for playing computer games.

The technology behind these plasma tv is quite different from LCD tvt. Thousands and thousands of small pixels with the color scheme (Red, Green and Blue) is used in the plasma tv. These primary colors combine to produce millions of variations of colors. A plasma tv consists of two panels that are filled in between with neon gas or xenon and as electricity is passed through the gas, it becomes liquid and start generating light. The light in turns lights the pixels and thousands of pixels together form a quality image. This process happens quite quickly up to 50 frames
per second. Therefore it is recommended to get a plasma tv if you are watching movies etc. Plasma tv has a higher colour resolution and clearer picture image than LCD TV.

You cannot say that plasma tv is better than LCD TV becuse it has already been stated that both are the latest technology and hve their own applicaions. lcd tv uses a panel of cells that are filled with liquid crystals and when the electricity is passed through these cells, the liquid crystals allows lights to pass through or be filtered. By blocking the different wavelengths of lights, the different colours are displayed. It works in a way like a prism. It is recommended to buy a LCD TV
if you use it for digital photography or playing computer games. The response time are better for LCD TV compared to Plasma TV and can be used as a monitor for your computer.

Plasma TV A Big Screen For a Little Room

One of the biggest drawbacks of the big screen television is the space needed for the television set itself. The plasma TV technology has made it possible to incorporate a big screen television into a small room. To understand how this change came about, briefly consider the difference in technology between a traditional television set and a plasma TV.

For the majority of time that television sets have been used as part of the home entertainment system, the television picked up a analog signal sent out by a broadcaster. That signal was analyzed by the television set and cathode ray tubes lit up the screen of the television. Thousands of tiny pixels make up the screen of the TV set in three colors - red, blue and green. Combinations of colors gave different hues as seen in real life and the result was a movie that (as nearly as possible) duplicated what we see in the real world. Digital television systems have increased the quality of the picture though many signals are still in analog form.

The plasma TV uses a different kind of technology for producing the picture though the reception is the same. In the case of the plasma TV, the pixels are lit up using something very similar to a fluorescent light. One of the biggest advantages is that the plasma TV technology uses much less space than the cathode ray tubes. This means that the plasma TV is only a few inches thick as opposed to the tube televisions that were large, bulky pieces of furniture.

This means that a smaller room that might not have been suitable for a big screen television set before could now have sufficient room. Because the screens are flat, you are also not dealing with the distortion at the edges of the screen and don't really have to be directly in front of the plasma TV to get a good view.

Plasma Technology for Your Television - A Few Reasons Why It's Good for You

Gone are the bulky monsters that gobbled up space and hunked down in our living rooms and bedrooms like contented sumo wrestlers. The old notions of video and home entertainment systems may just be a thing of the past. This is the dawn of the new television technology age and plasma may just be its greatest invention.

Plasma television is one of the most popular TVs using high-definition technology. In terms of monster size and eye-popping images, plasma television offers a lot not only in quality but also in price. Since buying one of these will probably take a chunk out of your wallet, you might want to understand the technology that makes plasma hot and credible.

How Plasma Works

The concept of plasma display has been around since the mid-60s but it was only in 1999 when the first commercial plasma models came out in the US market. Since then, televisions boasting of plasma technology have become the top favorite for home entertainment systems.

Plasma technology uses fluorescent light that contain gas made of electrons and ions. The fluorescent light is made up of three basic colors: red, blue and green. These colors are the basis for every other color you see on a plasma screen and they form a single pixel. Once the plasma television is turned on, the gas inside the fluorescent light burn up and thousands upon thousands of pixels form to produce the images.

Why plasma is better

Plasma televisions have a lot of fans who not only like what they see but also want the glamour equated with owning the newest technology. Other than that, there are plenty of reasons why plasma reigns supreme. Here are some:

Picture quality

It offers superb picture quality in terms of image contrast and picture brightness. So when you see black on your plasma television, it's black and not a dark grey. That means that images shot in high contrast don't disappoint and even movies with a dark noir feel to it don't look so bad. That means when you're watching Batman Returns, you'll get to see all the action without getting confused as to who is punching whom.

Size

In terms of the wow factor in size, plasma televisions are on top of the game. From the modest 37-inch model to the more than 60-inch stunner, plasma technology allows you to get the best-looking big-sized televisions without sacrificing picture quality. Remember the time when screen size equaled bad resolution? With plasma technology, those days are long gone.

Images shown through plasma televisions look great at any size and as long as you have the wall space, they won't take too much of your living room floor either. Plasma TVs are supermodel-thin and can even be mounted on your wall in place of a beloved picture frame. So now, you won't have any reason to keep your den or living room floor neat and orderly because you can't blame the clutter on the TV anymore.

ROI and an excuse to stay home

One of the main reasons why some folks are hesitant about buying a plasma television is the cost. For now, plasma technology can be had for a steep $2500 and that's not the biggest-sized television on display, either.

If you think that's too expensive, think about this: plasma TVs did not start out cheap. When they first came out for commercial use, they cost about ten grand. But since production cost has improved over the years (coupled with the enthusiastic response to plasma technology), consider yourself lucky that you can get a plasma television at the price they come in nowadays.

As for the nagging thought of an ROI, think of all the movies you've seen last year and the years before that. With movie theater tickets set at about $10 (let's just use the higher average), your $3000 plasma television will probably pay for itself in less than three years, granted you watch at least 10 movies a month. Popcorn, a soda and gas for the car are not even included in that equation.

The technology behind plasma televisions gives you one more great reason to watch videos at home because it will pay for its own cost in a short period of time. You not only get to watch movies within the comforts of your own abode, you also get to enjoy theater-quality images without leaving the house.

Plasma and LCD Televisions - A Side-By-Side Comparison

Want to know if a plasma television or an LCD television would be best for your needs? Here's a side-by-side comparison that will help you make an informed decision ...

What's the difference between plasma and LCD TVs?

Plasma TV screens are made up of hundreds-of-thousands of gas-filled, colored light cells. When an electrical current passes through those cells they light up and produce a picture.

LCD TV screens consist of a layer of liquid crystals sandwiched between two glass plates. When electricity passes through the crystals, an array of tiny color pixels light up and produce a picture.

Which one has the best picture?

Plasma TVs produce a slightly more colorful picture than LCD TVs. This is due to the fact that plasma TVs display blacks better than LCD TVs, which creates better color contrast, and produces brighter colors.

LCD TVs produce a sharper picture than plasma TVs due to their higher resolution.

What sizes do plasma TVs and LCD TVs come in?

Plasma TVs range in size from 42" to 65" wide, while LCD TVs are as small as 2" wide and go up to 65" wide." LCD TVs are thinner and lighter than plasma TVs.

Which one is better for video games?

Plasma TVs can experience screen "burn in." This happens when a still image is left too long on a screen, resulting in a ghost of that image burned into the screen. LCD TVs do not have this problem and are therefore a better choice if you play lots of video games on your TV.

Does a plasma TV or an LCD TV last longer?

Plasma TVs have a screen life of 30,000 to 60,000 hours, whereas LCD TVs have a screen life of 60,000 hours or more.

How much do they cost?

I recently ran a price check for plasma and LCD TVs. The cheapest large-screen plasma TV was a 42" inch model for $999. The cheapest 42" LCD TV was $1,367.

The cheapest 27" LCD TV I found was $550, and the cheapest 32" LCD TV was $619. There were no plasma TVs smaller than 42."

So what's the bottom line?

If you're in the market for a 42" flat-screen or larger, a plasma TV will give you the most bang for your buck. If you want a smaller TV, or if you're really into video games, then I'd recommend an LCD TV.

Plasma Television: With Maturity Has Come Greater Dependability

During the holiday season of this year, millions of consumers will be considering the purchase of a new television. Those beautiful plasma screen displays will scream at shoppers from the display floor with their vibrant, life like colors and detail. But undoubtedly, wary shoppers will have heard the rumors or perhaps have known someone who bought a plasma television in 1999 which has already moved on to television heaven just seven short years later. It seems to a prudent shopper that perhaps a new plasma TV isn't the choice for them if a long term relationship is desired.

But are the rumors false? Has plasma undergone a bit of reinvention? Was this lack of longevity a symptom of a fledgling technology that has now perhaps matured? Is a plasma television now more reliable, a screen to be around for the long haul?

In a word...yes.

With lower power usage and changes with the mix of gases in the panels, the longevity of plasma televisions has been significantly enhanced. The lifespan of a television display is measured in "half life"; the hours of use before the screen has dimmed to only 50% of its original brightness. In recent years, plasma television manufacturers have been touting a half-life which is equivalent to that of other screens such as the higher priced LCDs; around 60,000 hours. From this, consumers can see that the lifespan of a plasma screen is dependent upon how much it is viewed. For instance, if a plasma television is on for 6 hours a day, 365 days a year (2190 hours per year), it should last just over 27 years.

Knowing this, it becomes clear that the life of the screen on a plasma television can be significantly influenced by how it is used. Turning off the television when no one is viewing it could certainly extend its life. Adjusting the brightness is important as well; maximum levels are seldom required or recommended and can unnecessarily cause pre-mature aging of the phosphors.

Additional changes over the years for plasma televisions include technologies aimed at reducing the risk of "burn in"; another significant concern about the "character" of plasma displays that developed during its youth. Features such as pixel shifting, pixel orbiter, and motion adaptation all describe methods of moving the image on a plasma screen which is imperceptible to the human eye but effective in reducing the risk of burn-in. With these added features, many plasma manufacturers now claim their screens have no greater risk of burn in than the traditional CRT, "tube" televisions.

As with anything, consumers need to compare brands as they aren't all created equally. Reviewing the facts from the manufacturer is important. In general, it is best to stick with the more reputable and well known brands as a bargain "off-brand" in the long term may not save money if the quality and dependability are lacking.

There are many excellent technologies to choose from when buying a new television. Which type of display is best is dependent upon each individuals wishes, but plasma televisions certainly deserve the full attention of buyers as they do not warrant the negative reputation developed during their formative years in regards to longevity.

Christine Peppler believes that consumers shouldn't have to possess a technology degree to be able to choose home electronics and entertainment devices. Take advantage of the wealth of simple to understand, useful information and shopping available on her website at http://www.homemedias.info/.

This Is Big. Monster Big. 103 Inch Panasonic Plasma Television

The new Panasonic 103 inch plasma television is out. The TH-103PZ600U with 1080p capability will have an expected SRP of $69,999.95 and is expected to be available for delivery in time for Christmas 2006. It will also offer a three-year in-home limited warranty, unprecedented in the industry.

In flat panel displays, plasma has technical advantages over other technologies, including LCD, when it comes to making larger size panels. Nevertheless, there are numerous technical challenges in making plasma panels that are larger than 100 inches measured diagonally while maintaining stable discharge and high picture quality across the entire surface of the panel.

Panasonic has overcome these technical hurdles by developing a new rib and phosphor for these super large panels. A "rib" divides each gas cell and prevents interference between adjacent cells to produce clear images. The 103-inch 1080p plasma panel, equivalent to four 50-inch panels in size, features consistent and uniform discharge, delivering the same accurate images from the center to every corner of the screen and brightness as the current 50-inch HD model (TH-50PX500). The panel incorporates Panasonic's 1080p HD high-speed pixel drive. The same high-speed pixel drive is used in the TH-65PX500 65-inch 1080p Plasma TV, which has been well received in Japan since its introduction last November, and the 50-inch 1080p Plasma unveiled at CEATEC JAPAN 2005 in October 2005.

The TH-103PZ600U provides stunning widescreen progressive display featuring full HD pixel resolution of 1,920 horizontal x 1,080 vertical, a contrast ratio of 4,000:1, and 4,096 equivalent steps of gradation. Its effective display area is more than 89.3? wide by over 50.2? high. The super-size 103? 1080p panel is equivalent in size to four 50-inch Panasonic plasma displays.

?Until now, the market for 100-plus-inch screens was dominated by front projection TVs. Panasonic now realizes another option in this sector. Our 103-inch 1080p PDP promises high quality images with high brightness, dynamic contrast, high resolution and excellent color reproduction that projection displays cannot match. We believe it will create strong demand as a multipurpose display for business, educational and medical applications as well as home theater use,? said Mr. Nagano, Director, PDP Device Business Unit of Panasonic AVC Networks Company.
