The plasma television is a relatively new type of television, with a flat screen display. It works by having a mixture of different noble gases in small compartments behind a panel of glass. The plasma TV derives its name from the reaction in which these noble gases are turned into plasma, which emits light and forms the display you see. Plasma TV’s are often compared to LCD’s (liquid crystal displays), another type of flat screen television that uses liquid crystals in front of backlighting or fluorescent tubes to produce images.

Plasmas and LCDs, flatter and lighter than tube televisions, are also less difficult to manage than traditional CRT (or tube) televisions. Though, on average, they are a hefty 5 inches thick and 100 pounds, recent advances in plasma technology will soon cut their thickness down to an inch and their weight down to 45 pounds. Consumers can now take some liberties in the placement of their plasma TV’s. Plasmas can easily be mounted on walls or placed on smaller stands.

Flat panel TV’s, like plasmas, also have a higher resolution than traditional tube televisions. Resolution is related to how many pixels there are in a square inch; the more pixels, the higher the resolution. At present, high-definition plasmas have resolutions that vary from 1024×768 (720p) to 1920×1080 (1080i), which is much higher than the maximum resolution for tube TVs-480 lines.

Plasmas even last longer than other types of televisions. Manufacturers and companies stress that an average plasma television has a life span of 60,000 hours. That is equivalent to a life span of almost 7 years, if the plasma is left on 24/7. Compared to a tube television’s estimated lifetime of much less than 5 years if left on 24/7, the plasma television is the best choice.

Plasmas surpass LCDs in both colour quality and contrast and conventional televisions in colour quality. Plasma TVs generate more vivid colours and blacker blacks than LCD TVs do, allowing for a clearer, more intense image. LCDs are limited by their backlighting, which escapes out through pixels that should be black. However, conventional TVs are the only ones capable of producing true black.

Plasmas also have a wider viewing angle than LCDs. When viewing the television from the side, higher above, or lying on the floor, plasmas retain their crystal clear picture much better than LCDs do. Due to the shutter effect caused by the backlighting on LCDs, the larger the viewing angle is, the more brightness variation an LCD television viewer will experience.

In older models of plasma TVs, the burn-in effect posed a significant problem. When an image (for example, a paused movie) is kept on the screen for too long, the image could be burned into the screen and still faintly visible afterwards. Plasma TV companies have worked to eradicate this problem with much success; while it is still possible for images to burn in, on newer plasmas the possibility is almost negligible.

Plasma televisions have almost no size limitations, as long as the consumer’s budget can cover a gigantic screen. LCD and CRT televisions, on the other hand, are constrained to a diagonal measure of about 52 inches.
