วันอาทิตย์ที่ 8 พฤศจิกายน พ.ศ. 2552

The plasma TV is a relatively new kind of television show with a flat screen. It works by a mixture of different noble gases in small compartments behind a glass window. Plasma TV derives its name from the response, issued in which these noble gases in the plasma, the light and makes the display shows are on. Plasma TV's are often (LCD liquid crystal displays) in comparison with a different type of flat panel display Televisions that are usedLiquid crystals in front of the backlight or fluorescent tubes to produce images.

Plasma TVs (and flat-screen TVs in general) are very easy to use. By its very nature plasmas than conventional Flat TVs (CRT's are also called) and therefore are lighter as well. Currently, an average of 5 cm in width and 100 pounds, its size will soon be lowered one inch in width and 45 pounds. This lack of mass in a new era of TV Placement announced;Consumers can now mount their plasmas on the wall without worrying about ruining the wall.

Flat-panel TVs, plasma, and also have a higher resolution than conventional tube televisions. The resolution is how many pixels it relates, are in a square inch, the more pixels, the higher the resolution. Currently, high-definition plasmas have resolutions that vary from 1024x768 (720p) to 1920x1080 (1080i), which is much higher than the maximum resolution for TV-480 TubeLines.

Flat-screen TVs have a longer life than CRT TVs. Most plasma manufacturers now claim that their television sets with a lifespan of up to 60,000 hours when CRT televisions have a lifespan of at least 5 years. Under the assumption that a consumer TV 3 hours a day, a plasma TV can watch up to 55 years!

Plasma TVs have both a better color and contrast ratio than LCDs. For plasma TVs, each pixel canbe virtually eliminated to produce a more natural blacks. However, LCDs use a backlight to shine through the "black" pixels, and damage to the contrast quality. CRT TVs have the best contrast, but to exceed both plasma and LCD displays, when it comes to color reproduction.

Plasmas also a wider viewing angle than LCDs. Lying When viewing the TV from the side, higher up, or on the floor, plasmas remain crystal clear picture much better than LCDs do. Because the triggerEffect, which will see the backlight on LCDs, the greater the angle, the greater the brightness variation of an LCD television viewer.

Plasma TVs have been criticized because of the possibility of their use in pictures. The burn-in effect occurs when a still image is displayed on the plasma's screen for a long time (for example, if a DVD is stopped and the plasma on the left side, burn-in result). A ghost that might remain on the screen after thePicture has changed. However, this effect is negated almost in the newer models of plasma TVs.

Plasmas also practically no restriction on size, depending on the budget of the consumer, can go plasma screens up to any size. LCD and CRT televisions, on the other side about 40 inches diagonal are limited.
