Plasma TVs are a new set of display that uses technology ultimately different from other televisions. Although Plasma displays are not a new invention ( survey on them dates back for decades ), it is only recently that the technology to manufacture Plasma TVs at a relatively cheap price have been developed. Demand Plasma TVs have now been on the mart for many years. They initially 'wow' many home theater enthusiasts with their size and weight (and particularly their thinness), but original displays were very worthy and lacked image quality comparable to differential technologies.
However, with advances in manufacturing technology, Plasma TVs are now a workable, and in many ways good, preference to other display types. Plasma TVs are now available in a wide difference of sizes, ranging from 32 to 63 inches large, and with larger displays on the horizon. The image quality has highly improved, as have sharpness, black levels, and brightness. Prices have further come down dramatically, and many shoppers can now inspect Plasma TVs to be cheap enough to buy.
So, how do Plasma TVs work? What makes them different?, a Plasma TV works by suspending an inert gas such as neon or xenon in between two glass plates that are meshed together. Between the glass panels there are generally over 1 million pixel cells capable of producing 16.7 million colors. This inert gas is excited by a charge from an electrode, one per pixel of the display, turning it to plasma (for the name), and causing ultraviolet light to be created. Of course, we cannot watch UV light, but this light is used to brighten phosphors built into the glass, creating visible light. Since each pixel includes red, green and blue phosphors, the usage for space is reduced. Also, since each pixel includes all three colors, there is no need to scan the picture as with usual cathode-ray tube displays, allowing Plasma TVs to produce greatly bright and colorful displays.
In less technical terms, Plasma TV displays can be though of as having 1 million or more microscopic light bulbs (pixels) arranged between glass plates. These pixels are illuminated by plasma gas, and are able to produce red, green, and blue individually, and any of 16.7 million colors in between. The bulbs are controlled via the television 's microprocessor corresponding to the images that are to be viewed.
