But how does plasma technology work? It's pretty simple. Some form of inert gas- say Xenon, for example, is inserted between two plates, which are held together, between which are over two million pixels, capable of producing a mind-boggling array of colors. The gas is then energized by a charge which turns it into a viscous substance, creating an ultraviolet light, which allows each pixel to display the appropriate color. Unlike rear-projection TVs, each pixel in a plasma display contains red, blue, and green phosphors, there is no need for a cathode-ray tube. In traditional TVs, the cathode-ray tube, or CRT, fires electrodes to the screen, where they excite phosphor atoms causing
them to light up, thus creating a picture. The CRT is bulky and is responsible for the box-shape of traditional televisions. For example, if you want to increase the size of the screen in a CRT, you must also create a larger cathode-ray tube, therefore making the whole TV that much bigger- and bulky.
One drawback to plasma technology is the inability to recharge each individual pixel. Each pixel is an independently sealed entity, as is the plasma display panel and the gas, so if a pixel, or a group of pixels, fail or darken, the entire panel unit must be replaced.
Fortunately, however, you can expect your plasma display to last at least 60,000 hours of playing time, before the pixels begin to darken. So, in layman's terms, if you watch your TV for four hours a day, you can expect the panel to last around eighteen years.
Plasma technology has greatly increased the quality of home entertainment, ushering in a new era of television technology.
