The Basics of Plasma Televisions


Are you thinking about buying a plasma television for your home? As you may already know, Plasma televisions are becoming increasingly popular as of late, as the prices of Plasma Televisions are becoming more and more affordable each passing year. Plasma televisions can provide excellent viewing experience, and are perfect for those who want to enjoy a high quality home theater.

As with most technology purchases, there are advantages and drawbacks associated with this type of television as well. If you are new to Plasma TV, making a purchasing decision can be a little difficult. So before you rush out to buy your new Plasma television set, it's important to at least understand the basics of plasma television first.

Image Quality

One of the primary reasons that plasma televisions are so popular is their high quality image displays. Plasma television displays are bright and crystal clear, have a very wide color gamut, and also available in fairly large sizes. The large size is actually very interesting because it is something that a typical television sets could not be made without affecting the quality of the screen. These types of televisions (Plasma) offer very high resolution images with sharp details and true to life color.

Convenient

Plasma television sets can easily blend into the design of just about any room. These television sets are very thin in design when compared with other television, and can allow you to better utilize the square footage of your home. So instead of taking up a significant amount of floor space, plasma televisions can be hung directly on the wall or placed on a compact stand.

Longevity

Plasma televisions are not the most durable or long lasting television sets available. These types of television sets are difficult, if not impossible to repair. They generally last about seven years with normal usage. However, they are fragile and subject to irreparable damage when being moved from one location to another.

Pricing

Plasma televisions are priced at the mid range of television technology. They are less expensive than LCD television sets, but cost significantly more than analog sets.

Is a Plasma Television Right for You?

If you want to enjoy an affordable, high quality television viewing experience, a plasma television set can be a good choice for you. However, if you're looking for a set that will last for a decade or more, and can stand up to the rigors of frequently moves, you may want to choose a different types of television set.

Buying a Plasma Television

When you are in a store comparing with different plasma TV sets, remember that the employees there can be very helpful to you, especially since plasma TV is such a large ticket item for them. Therefore it is more likely that they are going to be more than willing to let you do or ask things that you normally would not be able to. And in terms of testing out the product, make sure you like it before you make your final purchase decision.

Plasma Television - It's a Gas


You can easily get overwhelmed by be the wide array of television sets that are now available if you want to shop around for a television set. In this day and age, there are a lot of state of the art television sets from the Asian region. There are also innovative display systems like liquid crystal display televisions and plasma televisions in the present market.

The cathode ray tube technology is the technology that is used in the tried and tested conventional televisions that most of us have grown up with. A cathode gun forms an image on a glass screen by charging and firing electrons on the screen. These images form as pixels in the three basic colors, which can produce millions of colors when combined. This technology has been fine tuned and developed through the ages to give us great television monitors. However, there are certain limitations to what the conventional cathode ray tube television can do.

For example, the screen of the cathode ray tube or conventional television has a size limitation because it is built of glass. Most conventional televisions which use the cathode ray tube technology are less than 42 inches in size. This size is the diagonal distance between from one end to the other and not the height or width of the television. This means that the biggest conventional television you can have is around 42 inches. Conventional televisions are also bulky, restricted in image size and confined to the limitations of the box they are built in.

Newer display technologies have resulted in better, modern televisions like the plasma television. The older cathode ray tube technology has been left behind in favor of an atomic technology in modern televisions. Our viewing experience has been enhanced by our ability to manipulate and control the behavior of atomic particles. This is the technology that is being used in a plasma television. A plasma is a gas that contains freely flowing ions and electrons. Photons are released and provide illumination when an electric charge is passed through this plasma.

This illumination is used by the rest of the technology in plasma televisions to create the three primary colors and to display them as images. This modern television also varies the intensity of the illumination to produce color changes in the same way the cathode ray tube televisions use different intensities of particles to produce different colors.

Most of the drawbacks of the conventional television are negated in the design of the plasma television. Size is no longer a restriction because the bulky cathode ray tube is not being used. The plasma television is also very thin so bulky boxes are not required. These days, most plasma televisions appear more or less like works of art hanging in your living room.

The Plasma Set Television- How it Works and Why It's a Good Reason to Buy a New TV


Long before plasma set televisions made their appearance, people bought TVs for their size. The bulkier, the better and whoever got the biggest, meanest television screen won the game of one-upmanship with his neighbors.

And then picture quality came along. The game quickly shifted into whose TV made the grass look greener and Halle Berry better looking than she already is. These days, the gold medal probably belongs to plasma television sets.

Why plasma television set looks so good

If you have your old CRT (cathode ray tube) TV, you've probably been amazed at the technology that made pictures come alive through the screen. CRTs also use pixels or dots that when grouped together, form a bigger image. CRTs basically use a vacuum tube that fires electrons against phosphors. Three phosphors make up one pixel, which is made of red, blue and green colors.

The CRT technology has a measure of control on which phosphor group to hit and depending on the strength and length of the hit, the picture tube shows us an image with color and light contrast.

Now CRTs perform well and are in fact still popular in many parts of the world. The only drawback is that they are heavier, fragile and eat up a lot of living room space. You've probably noticed the same issues with your older computer monitors.

With a plasma television set, the technology is different. Gas inside a fluorescent light is excited to a degree and transforms into a plasma state. Pixels are still made with the same three basic colors, but since plasma can be aimed more precisely, more pixels can be hit to form an image. The result? A clearer, prettier picture on the television screen.

Not only is high resolution a feature that plasma television sets boast of, there are also the colors - all 16 million and more of them. Imagine watching the TV and knowing there are millions of different colors dancing right in front of your eyes even if you can only name a few. There's dragon red, leaf green, ocean blue or maybe canary yellow and egg white, but that's just a drop in the bucket of all the color possibilities that plasma television sets can offer.

The view from the other side

Another reason why plasma television sets win a lot of admirers is that it gives the concept of 'sitting in front of the television' a whole new meaning. Remember when kids used to fight for the 'best seats' right smack in the middle for TV viewing? This is no longer true with plasma TV.

With rear projection TVs, the viewing angle is about 45 degrees to the sides. A plasma television set can give you perfect images even at 160 degrees! You can walk from one side of the room to the other and you will still have the same picture quality, so don't worry too much about Aunt or Grandma sitting to the sides of the plasma television set. They are enjoying themselves just fine.

The flatness is also there for a reason other than giving the excellent viewing angles; it also reduces glare. With a plasma television set, you don't even have to dim the lights for better viewing. It works just as well even with ambient light turned to the max.

Issues and myths

No, you cannot refill your plasma television set's plasma content or that it's too radiation-heavy. Those are urban legends that are too silly to be even given a second look. Plasma television sets are a product of the latest technology and as such, still have a few issues here and there.

One of the most common is the burn-in issue, where a plasma television set develops a burned-in image when it's tuned in for too long to a static picture. There is also the half-life expectancy where plasma televisions are expected to burn a little dimmer after a few thousand hours.

These issues are quite true, but the real threat to the life and quality of a plasma television set is really a matter of wise and careful use. If you keep it on hours and hours on one channel with a static image, then a burn-in issue might emerge, but this will only happen after hours of day-in and day-out use. The half-life has also improved from the 30,000 hours (allowing you 9 years of plasma TV use for 8 hours of viewing a day) to 60,000 hours.

The Holy Grail of television sets?

For now, plasma television sets offer a lot to drool about but many would-be fans are put off by its price. Imagine paying about $2,500 for a 42-inch plasma TV. However, plasma televisions are priced that way for good reason - they offer tops in picture quality and contrast and even with the monstrous size some models are available in, you won't want a lot in the resolution department.

Getting a plasma television set instead of an LCD or some other high-def TV is really a matter of personal choice and budget. Shop for the unit that's perfect for you and enjoy all the other benefits you won't otherwise get had you made a different choice.
