Plasma televisions
Definition
According to Plasma.com, a plasma tv is "a flat, lightweight surface covered with millions of tiny glass bubbles. Each bubble contains a gas-like substance, the plasma, and has a phosphor coating. Think of the bubbles as the pixels. Now, think of each pixel-bubble as having three sub-pixels - one red, one green, one blue. When it is time to display an image signal (RGB or video), a digitally controlled electric current flows through the flat screen, causing the plasma inside designated bubbles to give off ultraviolet rays. This light in turn causes the phosphor coatings to glow the appropriate color making your Plasma TV provide the best video image anywhere."



TechEncyclopedia states that plasma displays, or gas discharge displays, are "a flat-screen technology that contains an inert ionized gas sandwiched between x- and y-axis panels. A pixel is selected by charging one x- and one y-wire, causing the gas in that vicinity to glow. Plasma displays were initially monochrome, typically orange, but color displays have become increasingly popular with models 40 inches diagonal and greater being used for computer displays, high-end home theater and digital TV."



Market
There are numerous uses for Plasma Televisions besides simply updating your home theater system with the best possible picture whilst saving space. The following are ideas from the TV Authority.
  • Network Control Rooms - control room or network managers can constantly view the network performance
  • Meeting Rooms - make your meeting room PC friendly
  • Corporate Lobbies - display your companies products, services,  or events
  • Updatable Signage - share video or data with your employees or customers
  • Touch Screens - create an interactive digital work board
  • Video Conferencing - ideal display system for video conferencing






Major Manufacturers
There are numerous manufacturers of plasma televisions. Home Theater Magazine states that "Sony, NEC, and Gateway units are considered consumer models, while the others are labeled as commercial or professional models. They are sold through commercial distributors for use in business and/or industrial locations. You won't likely find these models at your local Best Buy or independent retailer, and the manufacturers normally wouldn't promote these products for home theater use."

Depending on the size of the television set, you could pay anywhere from $3000 to around $20000 for your plasma television.

According to the Plasma TV Buying Guide, "the concept for plasma display panels was first conceived in July 1964 at the University of Illinois. The first displays were nothing more than points of light created in laboratory experiments. From then on, the technology was developed and improved and by the late 60's, it had become advanced enough to allow the scientists to construct geometric shapes. Further development was limited, scientists were restricted by the materials that were available, so screens were small, and image quality was low. Today the progression in high speed digital processing, materials and advance manufacturing technology, has made full colour, bright plasma displays possible."

InfoComm had an article concerning the market penetration of plasma televisions. It stated "TFCinfo Corp reported in its latest U.S. Plasma Market Analysis Report that the global Plasma Display Panel (PDP) market will grow by 87 percent to 1,067,000 units in 2003. Due to increased resolutions, better scaling algorithms and sharply lower prices, the use of PDPs has increased tremendously in 2002 and will continue its rapid growth in 2003. TFCinfo also reports that the global market for PDPs will grow at a compounded annual growth rate of 82 percent through 2005. At present, the United States is the smallest PDP market among the top three world regions, behind Asia and Europe. We accountfor less than a quarter of the global PDP market. Yet, U.S. PDP penetration will increase markedly in the next few years. Market growth will outpace other regions due to initial low penetration, early U.S. economic recovery and growing consumer interest in digital TVs. In fact, in the third quarter 2002, U.S. plasma displays used for consumer applications (home entertainment) surpassed the use of plasma displays by businesses for the first time." See Article

From Plasma TV Buying Guide

The downsides of plasma TV are clearly outnumbered by the upsides. There are, however, a few negative aspects.
  • Price - For the most part, units are still on the very expensive side
  • Black and White Performance - TechnoFile claims it has weak B&W performance
  • Pixel Failure - Some have claimed that the pixels begin to fail after relatively short use, but an article in USA Today reports that it is untrue and impossible.

Plasma TV Specialists and Buying Guide

I could not find much on regularoty concerns regarding plasma TV's, but Plasma TV Buying Guide does warn about fraud companies who are offering prices that are too good to be true. The following companies were all found to be set-up solely to defraud customers into wiring large amounts of money overseas.
  • Plasma4all.com
  • Plasma-Zone.com
  • Electronic-Zones.biz
  • EZ-Electronic.com
So if you see a company that is offering plasma TV's at $1000 or so less than a reputable US store, be careful.

Plasma televisions will without a doubt become more successful than they already are. As prices continue to drop, and with manufacturers like Gateway releasing extremely competitively-priced units, the number of plasma sets purchased are guaranteed to increase. Also, with the change to Hi-Def just around the corner, consumers are sure to buy plasma TV's because of their space-saving design and incredible picture. It is in the very near future that almost all home theaters will be centered around a plasma TV hanging on the wall. Since plasma sets are state of the art, if they were to one day become obsolete, it would be decades into the future. This technology will be with us for a very long time.
