The History of Plasma TV
May 10, 2007
Plasma TV is one of the most sophisticated products available in the electronics market in recent times. Originally developed as a technology for big-sized televisions, plasma display has revolutionized every aspect of TV viewing with its excellent picture quality, image depth and most importantly, its exact facsimile of real world with billions of colours.
Today, we have a wide range of digital video devices like HDTV, DTV, and DVD that boast high quality image production but require excellent output devices like Plasma Display or LCD (Liquid Crystal Display). The larger Plasma Display Panels (PDP) with their excellent brightness, their faster response time, wider viewing angle and greater colour range has an edge over LCDs in terms of affordable price.
The concept of Plasma Display Panel dates back to 1964 when Donald L. Blitzer, H.Gene Slottow and a graduate student Robert Wilson designed the first single colour plasma display panel at University of Illinois for Plato Computer System.
Plasma display Panels were originally monochrome and had either green or orange display for the next two decades. Although Plasma display Panels were popular in the early 1970s for their huge screen size and sleek profile, they were generally used in multi-viewers environment like stock exchanges or big halls.
Fujitsu, a Japanese company designed the worlds first multi-colour display with 21 screen in 1992. In 1996, Panasonic, another Japanese electronics company bought Plasma co, an American based company and its technical expertise in plasma technology and started to manufacture Plasma Display Panels. However, only in 1997, the first commercial Plasma Display Panel entered the market and began to gain popularity in the subsequent years. In 1998, Plasma Display Panel was used for televising Olympic events and it turned out to be a great success. The electronic giant Panasonic built worlds largest Plasma TV in
Plasma Displays have better compatibility with almost all video formats - VCR, DVD, DTV and HDTV and even digital DVI connectors. They make excellent display devices for home theatres, video presentations in schools, colleges, training centers and video conferencing in business.
The use of plasma TV in public display system is immense. Larger plasmas make excellent display systems in stadiums, highway terminals, big halls in hotels or banks, advertising panels etc. Larger Plasmas (above 42 inches) are certainly cheaper as the LCD of the similar size will cost almost thrice.
What is Plasma?

Plasma is a special form of matter, which is unique from solid, liquid and gaseous states of matter. Although plasmas have a few common, fundamental properties with gases like indefinite volume and size, they significantly differ from gases by their electrical properties. A typical gas, like air, is electrically neutral, as the number of positive charged particles and negative charged particles in their atoms are equal in number. However, when a source of energy like heat or electricity is introduced into this state of equilibrium, it makes some or all negative particles (electrons) get loose, added or lost, thus making the gas ionized or electrically charged. It is the degree of ionization which actually determines the state of plasma. Thus, plasma refers to an ionized gas with unique properties like good electrical conductivity and their strong interactive nature in the electromagnetic fields.
Plasma has a wide range of applications in the present world. For example, neon signs and fluorescent lamps use noble gases like argon, neon, and xenon, which become plasmas when the electric current is passed in the tubes containing these gases.

Plasma TV : Why it is better than LCD?

Choosing a right flat panel display for your home can be easier than you think. All you have to do is a simple comparison of Plasma TV and LCD TV in correlation with your needs. If you want a huge display for your home theatre usage, Plasma TV will be an excellent choice.
To begin with, Plasma TV is compatible with almost all video formats NTSC, Pal, DVD and HDTV. Almost any video input device can be connected to Plasma TV. Moreover, Plasma TVs are upgradeable to add advanced features that come up now and then in the market.
DVD materials are best viewed when they are supported by a display device which can render excellent black levels and wide viewing angles. The true black levels enable the viewers to see the finest details in a dark back ground, in other words, the pictures look more realistic on a Plasma screen. This is because, Plasma TVs usually have a contrast ratio of more than 3000:1 while the high end Plasma TVs come with a contrast ratio of 10000:1.
Viewing angles imply how far your TV can allow you to sit on either side of it and enjoy the uniform picture quality. The more the wide angles your TV allows, the farther you can sit on either side of your TV. As each pixel on a Plasma screen is a self-illuminated unit controlled by a digital board, the picture quality does not get affected when pictures are seen off-axis. A standard Plasma TV supports a viewing angle up to 180 degrees.
The newer HD Ready Plasma TVs that hit the current market often have a competitive price combined with some of the advanced features that make them comparable with the best LCD TVs. While most of the LCD TVs suffer from motion lag or ‘ghosting, fast movements on a Plasma TV are devoid of artifacts, so look very real to the viewers.
Plasma TV : The best Flat panel for your home?

Many people are awe-struck when they watch a big sporting event or some HDTV material from a DVD player, on a 63 flat panel, plasma TV. It is the larger-than-life display that makes plasma TV, one of the finest, most coveted electronic products, without doubt. The conventional CRT TV looks bulky and lacks graceful looks. In comparison, Plasma TV has an extremely thin profile of 4 in depth or even less and you can fit them on the wall providing it is done by a professional.
