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.

Also between the glass plates are long address electrodes and display electrodes. When the electrodes are charged, a voltage difference occurs between the front and back of the display, which then triggers the gas to ionize and change into plasma. As the gas ions journey to the electrodes and run into each other, the crash makes photons.

When the electrodes are charged, they create a voltage difference between the front and back, which then causes the gas to ionize and turn into plasma. As the gas ions travel to the electrodes and smash together, the impact creates photons. The pixels are made of three unique sub-pixel cells, each with its own distinctive colored phosphors. One is red, one is green, and one is blue; the colors blend and produce the overall pixel color, and plasmas utilize pulse-width modulation to control image brightness.

Advantages to Plasma Television

Plasmas reach improved and realer color than other displays and preceding display technologies. This is what makes them so desireable.

They also produce more magnificent and more authentic blacks, which permit more refined contrast ratios. Plasma technology also makes possible much wider viewing angles that keep image quality at steep 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 Drawback Of Plasma TVs

Previous plasma technology is susceptible to screen burn-in and image retention. This occurs when you can still see the last displayed image on the screen for a time after the display is powered off. This was much improved in the newer technology, as more recent models now have green phosphors and other included technologies that eliminate this phenomenon.

For those who have had their plasma for a long time, the phosphors in those older models lose brilliance over time, resulting in the gradual degradation of absolute image brightness.

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 problems with them working at high altitudes because of the pressure discrepancy between the gasses and air pressure at altitude, and at such heights, the screens can make a buzzing sound.
