Plasma TV produces a high-quality picture with no glare.

If you want great image quality, a larger viewing angle and a glare-free visual experience, then a plasma TV is the cutting edge technology that you will want. It even has a great price starting at about $5,000. Hmm... Alright it's pricey, but at one time so were PC's. So let's see what the fuss is all about.


How Does Plasma TV Work?

Plasma technology operates between two thin panels of mounted glass found within the screen. A network of pixels that produce over 16 million colors is at the heart of the plasma TV. Each pixel contains three-subpixels made up of red, green, and blue phosphors.


Advanced electronics make up the inner workings. When an electrical current is applied to a pixel, the gas reacts to form plasma which in turn produces UV light. The light reacts with the colored phosphors and enhances the flat screen to produce higher-contrast ratios and a better picture.


The viewer never sees a flickering screen because all the pixels emit light at the same time. This all comes from a TV that ranges from three to just over six inches thick.


Advantages of Plasma Displays


If you are going to spend that kind of money, what will you get? Well, there are several features worth looking at. Here are some of them:


Higher Resolution

The aspect ratio of 16:9 is similar to the aspect ratio seen in the theater. This is the relationship between the screen's width and height. HDTV also uses this aspect ratio and it also allows many DVD movies to be viewed in widescreen format.


Flat Screens

Plasma display monitors have no curvature whatsoever; the screens are perfectly flat. Edge distortion that can occur in CRT displays is eliminated.



Uniform Screen Brightness

Hot spots are eliminated. Hot spots can occur with rear and front projection televisions. These are uneven screen brightness spots in the middle of the screen or near the edges and corners. Plasma displays illuminate all pixels evenly across the screen.


Wide Viewing Angle

The viewing angle of 160 degrees, top to bottom and left to right is much better than TVs and LCD displays. You can view the image reproduction from a wider variety of locations throughout the room.


Display Capability

Plasma monitors can accept a wide variety of video formats. You can use RGB inputs which means it will accept the video output from a computer. HDTV format is also available to plasma TV.


Immunity From Magnetic Fields

Because plasma displays do not use electron beams, as conventional TV displays do, they are immune to the effects of magnetic fields. Plasma displays can be placed close to any type of loudspeaker and not distort the image. Components such as loudspeakers that contain strong magnets can distort the picture if placed too close a standard TV, but they won't have that effect on plasma TV.


Slim Design and Space Saving Features

Plasma display monitors are very thin at anywhere between three to five inches. This provides installation options not available before. Stand mounting is possible, as well as wall hanging or from a ceiling hanging. Plasma monitors have a picture frame appearance that blends with any décor. The chassis is not much wider than the display screen itself.


HD Plasma TVs are the Best for Your Money

HDTV forms of plasma TV are the best technology for the price. You get the clarity of digital TV and the depth of color from plasma TV. If you are going to spend the money for the home viewing experience, then this is the way to go.

In an nutshell, how does plasma TV work? The screen is made up of pixels which are the small dots that receive the signal. The gas reacts to form plasma as the electrical current is applied to the pixel, which in turn produces UV light. The light reacts with the colored phosphors to produce higher-contrast ratios and a better picture.
