Savvy consumers have been enjoying plasma TVs for a number of years, but they are still considered to be rather new, so it’s not easy to predict how long your’s will last. Plasma TVs are lightweight televisions with a flat surface that is made up of millions of tiny glass bubbles. Each of these bubbles contains a gas-like substance, which is known as plasma.
The plasma display on these TVs is really one of the most exciting consumer electronics products to debut in the past decade. These televisions are remarkable, unlike any other on the market today.
Life of a Plasma TV
One of the biggest questions that consumers have regarding plasma TVs is what the life of a plasma TV is. This TV’s life span expectancy has been a hot topic for quite a while now, and rightly so. After all, they are generally at least a bit more expensive then the basic television sets and so consumers want to know whether it is worth it to shell out a bit of extra cash.
When it comes to the issue of the life of a plasma TV, there are a few factors that have to be taken into consideration. Although most of the 1999-2000 models have already passed on, as newer models continue to come out their life span gets longer and longer.
The life of a plasma TV then varies, depending on what year of television you decide to get. The newer the model the longer its life will be, but also the more expensive so it will really depend on you and how much money you are looking to spend.
Help Your TV Last Longer
Keep in mind that there are a few different things you can do in order to make the life of a plasma TV in your case last as long as possible. For instance you should never leave static images on the unit, because this can result in the image burning into the TV and you will be able to see the image on the screen even when you change the channel or turn the TV off.
You should also use brightness and contrast levels that are necessary for viewing and not overdo it because again this will disturb the picture quality. At night if you can you should use lower contrast levels as this will help to significantly extend the life of the TV. Plasma TVs are a great purchase and definitely worth every penny, and by keeping these helpful tips in mind you will be able to ensure that your TV lasts you as long as possible.

Plazma TV flat panel displays encompass a growing number of technologies enabling video displays that are lighter and much thinner than traditional television and video displays that use cathode ray tubes; they are usually less than 4 inches thick. They can be divided into two general categories; volatile or static.
Flat Panel Plasma Television - Volatile
Volatile displays require constant power output to refresh the image on screen many times a second. The image appears steady because the images are refreshed more often than the human eye can perceive.
Some examples of volatile flat panel displays are: plasma displays, liquid crystal displays, organic light-emitting displays, light-emitting diode displays, electroluminescent displays, surface-conduction electron-emitter displays, field emission displays, and nano-emissive displays.
Flat Panel Plasma Television - Static
Static flat panel displays rely on materials whose color states are bistable. This means that the image they hold requires no energy to maintain, but instead requires energy to change. This results in a much more energy efficient display, but with a tendency towards slow refresh rates which are undesirable in an interactive display.
Some examples of static flat panel displays are; electrophoretic displays, bichromal ball displays, interferometric modulator displays, cholesteric displays, and bistable nematic liquid crystal displays.
Flat Panel Plasma Television – How Plasma Works
Plasmas break pixels into sealed red, green, and blue sub-pixels, or cells that contain an inert gas. When an electric current, that is a derivative of the video signal, excites the gas, it causes the colored phosphors in each sub-pixel to glow. By driving each sub-pixel to the desired level, the signal determines the pixels exact color and brightness. By putting enough of these pixels close enough together, an image is created.
To stay ready to respond to the signal, the plasma cells inside flat panel plasma televisions remain partially on at all times, meaning that some light is inevitable, even when the signal tells the cell it wants black.
Some of the major manufactures of flat panel plasma televisions have re-engineered their sets to reduce this “idling” brightness by 80%. The result is mind-boggling, with the blackest blacks ever being produced in the history of television.
Flat Panel Plasma Television - Myths
Myth # 1 – Plasma TVs emit dangerous radiation. Plasma TVs do generate a tiny amount of UV radiation, but its even less than typical tube-type TVs generate.
Myth # 2 – The gas in a plasma TV is poisonous. The gas used in plasmas is a mix of two non-flammable “inert” gases; neon and xenon. These gases are not harmful, either individually or when combined.
Myth # 3 – Plasma TVs leak gas and require periodic “re-charging.” Each individual cell in a plasma panel is sealed, so a plasma TV will never require any re- filling or re-charging of its neon-xenon gas.

Panasonic plasma TV sets embrace newer technology which allows faster color changes and better replication of fast action on the screen. The newer Viera series Panasonic plasma TV provides for better contrast and color renditions in 1080 progressive scanning to render vivid color and action, regardless of the screen size.
High definition television sets are becoming a more integral part of the entertainment world as the industry works at meeting the government’s requirement for all broadcasting to be done in digital by the year 2009. With this shift to digital, consumers are benefiting from much better reproductions of shows on widescreen flat-panel televisions with some of the brightest pictures being viewed on a Panasonic plasma TV. With the brilliance seen in the newer models of plasma televisions, Panasonic is proving a leader in the innovations of larger screens for home viewing enjoyment.
When flat panel televisions were first being developed, the use of liquid crystal displays became all the rage, however the size of the screens were rarely larger than 27-inches diagonally. The Panasonic plasma TV development enabled television manufacturers to enlarge the screens, typically not smaller that 36-inches and the industry generally accepted the fact that LCD screens would be left for smaller markets while plasma technology could take over the larger screen market share.
The use of LCD screens was left for the health electronics industry and in computer monitors along with smaller screens for home television viewing. As plasma technology became more accepted, the screen sizes, especially for the 13:9 aspect ratio was booming in sales and now the Panasonic plasma TV is available in a variety of sizes for home use, up to 65-inches.
Technology And Competition Sparks Price Reduction
As with most new technologies, when the plasma televisions were first introduced they were out of the price range for most consumers. However, advances in technology and competition from other manufacturers, as well as the development of large screen sets by LCD manufacturers, the prices of a Panasonic plasma TV have fallen to become more affordable to a wider consumer audience.
Depending on the size of a consumer’s viewing room, they can find a Panasonic plasma TV ranging in size from 42-inches to 65-inches, with three additional sizes in between. Placement of the viewer’s seating will help determine the size of the screen, as sitting too close to a larger screen may cause some of the action on the edges of the picture to be missed.
