How Does Plasma TV Work So Well Today

So What The Heck Is Fourth State of Matter

We all want to know how anything works. That too, when we find a it fascinating we want to know more. In this process, we want to know How Does a Plasma TV Work.

For the past half a centaury or more, televisions have been made on the same technology known as the Cathode Ray Tube CRT.

In the Cathode Ray Tube technology, a beam of electrons are fired inside a large glass tube. These electrons stimulate the phosphor along the screen surface. The phosphor lights up.

Thus the image is produced on the screen. The CRT televisions are box like and bulky. They occupy a large space. The bigger the screen size the more room the television will occupy.

For years manufacturers and researchers have been trying to eliminate this bulky TV. In 1964 the first plasma TV prototype came to the scene. However, it took several years from there to perfect the Plasma TV to a commercially viable state. Compared to the CRT or conventional TV set, the Plasma TV is just only six inches thick and could be hung on a wall like a picture.

Plasma is referred to as the "Fourth State of Matter." The other three are solid, liquid and gas.

Plasma is a distinct state of matter containing a considerable number of electrically charged particles, a number sufficient to affect its electrical properties and behaviour.

In addition to being important in many aspects of our daily lives, plasmas are believed to comprise more than ninety nine percent of the observable universe.

Plasma panels are a collection of cells, known as pixels, which are composed of 3 sub-pixels, corresponding to the colours red, green and blue.

Gas in a plasma state is used to react with phosphors in each sub-pixel to produce coloured light (red, green or blue).
These phosphors are the same types used in conventional cathode ray tube (CRT) devices such as televisions and standard computer monitors.
You get the rich, dynamic colours you expect. Each sub pixel is individually controlled by highly developed electronics to produce over 16 million different colours.
All of this means that you get perfect images that are easily viewable in a display that is less than 6 inches thick.

Because a plasma panel is illuminated at the sub-pixel level, pictures are tremendously precise, and the panel's light output is both high and consistent across the entire screen area.

Plasma TVs also provide very wide horizontal and vertical viewing angles, especially when compared to conventional Cathode Ray Tube TVs.

Picture quality looks razor-sharp and vivid from virtually anywhere in the room. Because plasma TV screens do use a phosphor coating, the possibility for image burn-in exists, so it's important to follow the manufacturer's recommendations on day-to-day use.

Until of late, all flat-panel TVs were progressive displays — at any given moment all of the pixels are illuminated. But plasma TVs based on innovative Alternate Lighting of Surfaces (ALS) are proving that a non-progressive picture can look exceptional.
