from: Did You Ever Wonder How Plasma TV Displays Work?
For the past 75 years, the vast majority of televisions have been built around the same technology: the cathode ray tube (CRT). This achieves quality color set-up, however, it has a disadvantage—it is very bulky.
Plasma Technology has been another option for TV fans. The said product has been the recent trend in the television technology industry with its high definition technology that defines its competitive advantage over the other television technology type.
Did you know why Plasma TV demand continues to raise high at the market? Did you ever think of how it works, such that it achieved a superior quality?
Plasma displays are bright have a wide color gamut, and can be produced in fairly large sizes. They have a very low-luminance "dark-room" black level compared to the lighter grey of the unilluminated parts of an LCD screen. The power consumption of plasma TV varies depending on the picture content and quality.
In a CRT television, a gun fires a beam of electrons (negatively-charged particles) inside a large glass tube. The electrons excite phosphor atoms along the wide end of the tube (the screen), which causes the phosphor atoms to light up. The television image is produced by lighting up different areas of the phosphor coating with different colors at different intensities
However, with the Plasma TV, the xenon and neon gas in a plasma television is contained in hundreds of thousands of tiny cells positioned between two plates of glass. Long electrodes are also sandwiched between the glass plates, in front of and behind the cells.
The address electrodes sit behind the cells, along the rear glass plate. The transparent display electrodes, which are surrounded by an insulating dielectric material and covered by a magnesium oxide protective layer, are mounted in front of the cell, along the front glass plate. Control circuitry charges the electrodes that cross paths at a cell, creating a voltage difference between front and back and causing the gas to ionize and form a plasma. As the gas ions rush to the electrodes and collide, photons are emitted.
The basic idea of a plasma display is to illuminate tiny, colored fluorescent lights to form an image. Each pixel is made up of three fluorescent lights -- a red light, a green light and a blue light. Just like a CRT television, the plasma display varies the intensities of the different lights to produce a full range of colors.
The CRT, LCD and the Plasma TV are a very different type of technology. Plasma is often cited as having better black levels (and contrast ratios), although both plasma and LCD have their own technological advancement. It is claimed that contrast ratio for plasma is at 30,000:1. Why do we talk now of contrast ratio? Science says that picture color quality is more enhanced when the color contrast ratio is very high.
Now that we fully understand how it works, this may justify such advancement defines the quality of the product. So the next time you shop for a new television set, try to look for a high definition Plasma TV.
