Plasma TV

Conventional Television produce crisp, vibrant images, and having much weight and bulky.To overcome this difficulties Plasma Televisions are developed which is 50% less weight than normal TV. Plasma televisions have wide screens, comparable to the largest Conventional TV sets, but they are only about 15cm thick.Normal TV using Cathode Ray tube and plasma using Plasma Gases to get the picture.

Advantages Of Plasma Television

Plasma Television can produce a very wide screen using extremely thin materials.

Higher Resolution(1024 x 1024 pixel) of Plasma Television gives superb picture quality than any other Television sets.

Plasma Television is not using electron beam and produces no scan lines.

The aspect ratio(width to height ratio) of plasma Television is 16:9 which is suitable for your home theater.

Currently Plasma Television is the only Television having maximum screen size(More than 50").

The display surface is perfectly flat, the picture is evenly focused throughout the screen surface, and colors are very accurate.

Plasma Television can display 17 million colors and you can view true picture.

Slim, Lightweight Design and you can watch Plasma Television from almost anywhere in a room, since flat screens have a 160° viewing angle.

Computer compatibility-You can use Plasma Television as a computer monitor.

Plasma Television History

The amazing Plasma Television, invented at the University of Illinois in 1964—seems to have finally found the problem (not to mention the goldmine) it always deserved: carrying high-definition television (HDTV) into millions of homes. The panel's single cell operated on the fundamental rules that govern the millions of cells in one of today's panels.By 1967, the inventors had figured out how to achieve good memory margin using just neon, and they had developed the driving circuitry necessary to address a large array of pixels. After finishing his PhD in 1975 with a dissertation on the discharge dynamics of plasma displays, Weber joined the CERL staff and began consulting to U.S. companies interested in such commercial applications of the Illinois technology.

Japanese companies were among the first to take out licenses and begin their own plasma display research, enjoying the support and encouragement of NHK, the government broadcasting system that had advocated HDTV as early as the 1960s. Among the prominent Japanese engineers who visited CERL to study plasma displays was Heiji Uchiike, now of Saga University. That's why Japanese companies like Matsushita and Fujitsu are finally in a position to see the payoff for their long commitment to plasma display panels. Weber does see the possibility of future U.S.-based manufacturing of plasma displays. But the companies will be Japanese, looking to move production closer to the growing U.S. market for their products.

Plasma Television Working Principle

The basic idea of a plasma television is to illuminate tiny colored fluorescent lights to form an image. Each pixel is made up of three fluorescent lights -- a red light, a green light and a blue light. Just like a CRT television, the plasma display varies the intensities of the different lights to produce a full range of colors.

The central element in a fluorescent light is a plasma, a gas made up of free-flowing ions (electrically charged atoms) and electrons (negatively charged particles). Under normal conditions, a gas is mainly made up of uncharged particles. That is, the individual gas atoms include equal numbers of protons (positively charged particles in the atom's nucleus) and electrons. The negatively charged electrons perfectly balance the positively charged protons, so the atom has a net charge of zero.

The phosphors in a plasma Television give off colored light when they are excited. Every pixel is made up of three separate subpixel cells, each with different colored phosphors. One subpixel has a red light phosphor, one subpixel has a green light phosphor and one subpixel has a blue light phosphor. These colors blend together to create the overall color of the pixel.

By varying the pulses of current flowing through the different cells, the control system can increase or decrease the intensity of each subpixel color to create hundreds of different combinations of red, green and blue. In this way, the control system can produce colors across the entire spectrum.

Plasma Television Life Span

The lifespan of plasma Television is measured relative to the half-life of its phosphor gases. The life span of the Plasma Television is around 25 years(8 working hrs per day basis).But after 10 years the brightness of the Plasma Television will be 96% of the original brightness level.After 25 years the brightness will be 85% of the original brightness level.But you can adjust the brightness by keeping high brightness level. Plasma Television Maintanance

The Plasma Television should not be exposed to high temperature, since high temperature may reduce the life span of Plasma Television.

Use high quality voltage stabilizer.

Keep the brightness of the Plasma Television at medium level.

Mount your plasma television in a well ventilated place to reduce the cooling load of plasma TV.
