Plasma TV’s and LCDs (liquid crystal displays) are both kinds of flat screened televisions. Plasmas work by transforming noble gases into plasma, which then discharges light to shape the display on the screen. Each small compartment of gases constitutes one pixel. LCDs, on the other hand, form their displays by placing liquid crystals in front of fluorescent or another type of backlighting.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.

Plasma TVs are easier to maneuver than traditional CRT televisions (also known as tube televisions). They are flat, with a width of 5 inches, and lightweight, weighing approximately 100 pounds each. In contrast, CRT televisions are much heavier and bulkier. This gives consumers more flexibility when deciding where to place their plasmas; they can be hung on walls or put on stands that support less weight. Manufacturers have even designed plasma televisions that weigh only 45 pounds and are only an inch thick.Plasma televisions (and flat screen TVs in general) are extremely easy to handle. Due to their very nature, plasmas are flatter than traditional televisions (also called CRTs) and thus, are lighter as well. Currently averaging 5 inches in width and 100 pounds, their size will soon be reduced to an inch in width and 45 pounds. This lack of bulk has heralded in a new era of television placement; consumers can now mount their plasmas on the wall without worrying about ruining the wall.

Resolution, the quantity of pixels on the television screen per square inch, is also a key component of televisions. Flat screened televisions boast a much higher resolution than CRT televisions, which yields clearer images on the screen. High definition plasmas have resolutions that range from 1024×768 to 1920×1080. This is much better than even the maximum resolution for tube televisions, a mere 480 lines.

Plasma television manufacturers boast a lifetime of up to 60,000 hours for their televisions, compared to a CRT television’s life span of at least 5 years. Which is better? Depending on how much a plasma is turned on, its lifespan can range anywhere from 7 years (turned on for 24 hours a day, 7 days a week) to 55 years (turned on for 3 hours a day). The lifespan of a plasma TV is significantly greater than that of a CRT TV.Flat screen televisions also have a longer life span than CRT televisions. Most plasma manufacturers now assert that their televisions have a life span of up to 60,000 hours, where CRT televisions have a life span of at least 5 years. Assuming that a consumer watches 3 hours of television a day, a plasma TV can last up to 55 years!

Color reproduction and contrast ratio are two important components of a clear picture. Plasma televisions excel in both; they produce richer, more vibrant colours and truer blacks than LCDs. Due to the backlighting in LCDs, any pixel that should be black will have some light leaking through, which spoils the contrast.

The image of both LCDs and plasmas is comparable when viewed directly in front of the screen. However, plasma televisions have a wider viewing angle than their counterparts. Backlighting causes this problem in LCDs; the image on the screen degrades as the viewing angle increases. Plasmas can be viewed from the sides or top and bottom.

Many worry about the possibility of burn-in images on plasmas. This occurs when a still shot is shown on the screen for too long. Afterwards, a faint outline or trace of the image may still be visible on the plasma’s screen. However, this should not be a serious problem with newer models, as manufacturers have worked to eliminate the burn-in effect.

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.Plasmas also have virtually no size limitations; depending on a consumer’s budget, plasma screens can go up to any size. LCD and CRT televisions, on the other hand, are confined to approximately 52 inches diagonal.
