The Evolution Of The Plasma Television
Plasma televisions have flat panel displays. Light is created by the action of a plasma discharge to the phosphorus between two flat pieces of glass. Compared to the other kinds of television screen such as the backlights of AMLCD, plasma television screens have no mercury. It discharges inert gas mixture of neon and xenon that are entirely safe to people and to the environment. These gases are contained in tiny cells that can be founds in between two panels of glass, where long electrodes can also be found. These electrodes are covered by a protective layer made from magnesium oxide.
The origins of plasma television screens
Donald Bitzer and H. Gene Slottow created the first plasma television at the University of Illinois in 1964 for the PLATO Computer system. Originally, it has monochrome panels of orange or green that were quite popular during the early 70s. The plasma television invention offered convenience because it no longer needs memory and circuitry. In 1975,
Larry Weber, also of the University of Illinois, decided to create a color plasma television using the same concept that Bitzer and Slottow used. Unfortunately, it was only in 1995 that he finally got the magic formula. Now, plasma televisions are all the rage because of the superior quality of its screens. The images are brighter and the viewing angles are better than other kinds of television screens that include cathode ray tube (CRT), OLED, AMLCD, DLP and SED-tv
Plasma TV For The Home TheaterOne of the hottest topics in home entertainment is home theater. And one of the hottest topics in home theater is plasma TV. .....
What’s inside a plasma television
Plasma televisions are bright. There is no doubt about that. In fact, it has 1000 lx brightness. Another feature that has people going gaga over this invention id the wide color range that is supports. Plasma televisions have higher dark-room contrasts compared to other kinds of television screens. It therefore creates a perfect black effect on the screen that are very ideal when watching movies. Images can also be projected in large sizes. What is more, all these powering very thin packages. The display panel of a plasma television only reach 6 cm on the average. If you will include the electronic parts, a plasma television screen will be around 10 centimeters thick or four inches. This is extremely think for today’s standards of really bulky television sets.
Despite its superior performance, plasma television uses the same amount of energy and power as the cathode ray tube (CRT) and AMLCD television screens. However, because the use of power is proportion to the size of the screen, large screened plasma televisions can really use up a lot of power, as much as 700 watts. This has prompted some critics of the plasma television to question its superiority as well as question its effect in the environment.
When it was first introduced, plasma televisions were really expensive. Since then, prices have been lowered so that the middle class home owners can also experience the luxury. Now, the prices of one plasma television has gone down to US$1900 or even lower depending on the brand. Another reason perhaps of the lowering of prices is the introduction of flat screen television sets in the market.
Plasma televisions have estimated “life” of 60,000 hours of display before it goes to a period that electronic geeks call half-life. This is the period when the picture on the screen has lost half of its original intensity and brightness.
