Plasma TV is a relatively new type of television, with a flat screen. It works by sending a mixture of different noble gases in small compartments behind glass. Plasma TV derives its name from the reaction in which these noble gases in the plasma, which radiates light and shapes you see are on display. Plasma TVs are often compared to lcd (Liquid Crystal), a different type of flat screen televisions that used in liquid crystalBackground lighting or fluorescent tubes to produce images.
Plasma TVs (and flat-screen TV in general) easy to use. By its very nature, plasma TVs are thinner than conventional (also known as CRT) and are thus easier to be good. Currently, an average of 5 inches wide and 100 pounds, is now a size in inches in width and 45 pounds can be reduced. This missing mass was ushered into a new era of television placement, consumers can now mount their plasmasthe wall without worrying about messing up the wall.
Flat-screen TVs as plasma have a higher resolution than traditional tube televisions. The resolution is related to the number of pixels there are in a square inch, more pixels, the higher the resolution. Currently, high-definition resolutions, the range of plasma 1024×768 (720p) and 1920×1080 (1080i), which is much higher than the maximum resolution of 480 TV lines cut.
Flat screen TVs have a longer lifespan of CRT TVs. Most plasma manufacturers now claim that their televisions will last up to 60,000 hours when CRT TVs have a duration of at least five years. Assuming a consumer to 3 hours of television a day, a plasma TV can watch up to 55 years!
Plasma TVs have better color and contrast ratio of lcd. For plasma TVs, each pixel can be virtually eliminated to produce true blacks. However, the lcd uses a backlight that illuminatesfrom "black" pixels and the quality loss of contrast. CRT TVs have the best contrast, but to overcome both lcd and plasma when it comes to color reproduction.
Plasmas have a wider viewing angle LCD. When you watch the TV side, higher, or lying on the ground, maintain their plasma crystal clear picture do much better than LCD. Because of the shooting caused by the LCD backlight, the greater the angle, the brightness of moreVariation of an LCD screen to viewers.
have plasma TVs, has been criticized because of the possibility, burn-in images. The burn-in effect occurs when a still image is displayed on a plasma screen for extended periods (for example, if a DVD is stopped and left the plasma occur Burn-In). A ghost image can remain on the screen after the picture had changed. However, this effect is almost the most recent models of plasma were deniedTelevision sets.
Plasmas have virtually no size limitations, depending on budget consumption, plasma screens can never grow to any size. LCD and CRT TVs are on the opposite diagonal limited to about 40 cm.
