Plasma Tvs - Why You Should Buy One
Plasma Televisions - What Exactly Are They?
They are flat panel displays that use two panes of glass to hold cells, which contain a mix of gasses inside. These displays are typically found in televisions and computer screens, along with other elctronic device displays.
Plasma television is completely different from LCD (liquid crystal display), which utilizes a very different process to produce its image.
The Technology Of Plasma TV
The noble gases contained inside of the cells in a plasma TV are xenon, neon, and helium; they are contained inside hundreds of thousands of minuscule cells detained between two plates of glass.
Each pixel is made of three characteristic sub-pixel cells, each with its own unique colored phosphors. One red, one green, one blue; the colors combine and create general pixel color. There are many benefits to plasma technology.
Usually found in televisions, digital cameras, and computer displays, they have a remarkably thin profile, weigh less and are more compact than conventional displays; because of this, mounting plasma displays on walls is very easy.
The Benefits Of Plasmas
There are many advantages to plasma image technology. Usually utilized in televisions, digital camera screens, and computer displays, they have an exceptionally thin profile, they are lighter and more compact than traditional displays; because of this, mounting computer screens and televisions on walls is very simple.
Plasmas achieve better and more accurate color production than other displays, also creating richer, more genuine blacks that allow advanced contrast ratios. Plasma technology also has far wider viewing angles for which images do not degrade at high angles.
Lastly, there is almost no motion blur because of a plasma TV's extremely high refresh rate and faster response time, which adds to its higher performance when projecting images with considerable amounts of quick motion.
The Shortcoming Of A Plasma TV
Earlier plasma TV models were vulnerable to screen burn-in and image retention. Not to worry though, more recent models now have green phosphors and other included technologies to do away with this.
In previous plasma displays, the phosphors lose intensity over time, resulting in the measured breakdown of overall image vividness. This is very disappointing, as plasma displays are not cheap, and users paid a significant amount of money for these previous displays, only to have them "wear out" fairly quickly.
They are also more prone to large area flicker and reflection glare in brightly lit rooms; they usually are not available in screen sizes smaller than 32 inches, are heavier because of the glass required to contain the gasses, and use more electricity than other available technologies.
There are also issues with them working properly at high altitudes because of the pressure difference between the gasses and air pressure at altitude; also, at altitude it has been noted that the displays can make a "buzzing" sound.
