What is a plasma tv?

Answer 1

it's the mirrors

Answer 2

It's one of the 3 display technologies being used in flat panel TV technology. Plasma, LCD and LCOS. The best about any of these flat panel technologies versus standard tube TV's is because these TV's offer higher resolutions, support HDTV and better color output.

Plasma offers deeper colors and softer picture. It's the ideal technology for video. Though, others will swear that LCD is better. It's a personal preference.

If you want to know how it works, you can visit Wikipedia. But, I figured you just wanted an overview.

The plasma display panel was invented at the University of Illinois at Urbana-Champaign by Donald L. Bitzer and H. Gene Slottow in 1964 for the PLATO Computer System. The original monochrome (usually orange or green, sometimes yellow) panels enjoyed a surge of popularity in the early 1970s because the displays were rugged and needed neither memory nor circuitry to refresh the images. A long period of sales decline followed in the late 1970s as semiconductor memory made CRT displays cheaper than plasma displays. Nonetheless, plasma's relatively large screen size and thin profile made the displays attractive for high-profile placement such as lobbies and stock exchanges.

In 1983, IBM introduced a 19-inch orange-on-black monochrome display (model 3290 'information panel') which was able to show four simultaneous IBM 3270 virtual machine (VM) terminal sessions. That factory was transferred in 1987 to startup company Plasmaco, which Dr. Larry F. Weber, one of Dr. Bitzer's students, founded with Stephen Globus, and James Kehoe, who was the IBM plant manager. In 1992, Fujitsu introduced the world's first 21-inch full-color display. It was a hybrid, based upon the plasma display created at the University of Illinois at Urbana-Champaign and NHK STRL, achieving superior brightness. In 1996, Matsushita purchased Plasmaco, its color AC technology, and its American factory. In 1997, Pioneer started selling the first plasma television to the public.

Screen sizes have increased since the 21-inch display in 1992. The largest plasma video display in the world was shown at the (Consumer Electronics Show) in Las Vegas, Nevada, U.S.A., in 2006, measuring 103 inches and was made by Matsushita Electrical Industries (Panasonic).

Until quite recently, the superior brightness, greater color spectrum, and wider viewing angle of color plasma video displays, when compared with LCD televisions, made them one of the most popular forms of display for HDTV, however, since then improvements in LCD technology have narrowed the technological gap. The lower weight, cheaper price, and lesser electrical power consumption of LCDs make them competitive against plasma displays in the television set market.


[edit] General characteristics
Plasma displays are bright (1000 lx or higher for the module), have a wide color gamut, and can be produced in fairly large sizes, up to 262 cm (103 inches) diagonally. They have a very high "dark-room" black level, creating the "perfect black" desirable for watching movies. The display panel is only about 6 cm (2½ inches) thick, while the total thickness, including electronics, is less than 10 cm (4 inches). Plasma displays use as much power per square meter as a CRT or an AMLCD television. Real life measurements of plasma power consumption find it to be much less than that normally quoted by manufacturers. Nominal measurements indicate 150 watts for a 50" screen.

The lifetime of the latest generation of plasma displays is estimated at 60,000 hours[citation needed] of actual display time. More precisely, this is the estimated half life of the display, the point where the picture has degraded to half of its original brightness, which is considered the end of the functional life of the display.

Competing displays include the CRT, OLED, AMLCD, DLP, SED-tv and field emission flat panel displays. The main advantage of plasma display technology is that a very wide screen can be produced using extremely thin materials. Since each pixel is lit individually, the image is very bright and has a wide viewing angle. Most cheaper consumer displays appear to have an insufficient color depth - a moving dithering pattern may be easily noticeable for a discerning viewer over flat areas or smooth gradients; expensive high-resolution panels are much better at managing the problem.

its a TV that's flat and hangs on the wall
