What is a plasma TV?
Plasma TV is a high -resolution alternative (HDTV) to standard cathode Ray TVs sold today. Plasma television provides sharp images and vibrant colors, especially when used in conjunction with high -resolution broadcasting. Quite often, plasma television is designed in a 16: 9 ratio for a wide-screen film formats, unlike standard TVs as a box-similar 4: 3. Units start at $ 2,000 and can be up to $ 15,000 or more USD. Investors on plasma television can also use theater speakers and top receivers with ambient sound to complete the feeling of luxury. TV in Plasma has become symbols of the state between technophiles and other rich consumers. 'Plasma'j is a scientific term referring to gases like neon and xenon, which shines when exposed to an electric field. Plasma is sometimes called the fourth state of matter, in liquids, solids and gases. Think of a neon mark or fluorescenceA straight to understand the plasma how it is true here.
TV generally rely on thousands of small "picture elements" shortened as pixels. With any color television, the bundle of three separate colors includes one pixel, usually red, green and blue. By steering the level of each color, all other spectrum colors can be created in each pixel. The viewer is usually so far from the screen that the individual pixels are blurring and the illusion of movement creates when changing color. This applies to any TV system, plasma or otherwise.
In plasma TV, the individual pixels are made of three small containers, such as neon or xenon. There are literally hundreds of thousands of these small tubes on the average screen of plasma TV screens. All these individual pixels are sandwiches between two electrically charged plates. Remember that plasma glow when Elek is exposedtricked stream. A computer processing unit receives signals from a cable or transmitted antenna that tells her how to re -assemble the entire picture hundred times per second.
The computer controls the electric field down to the individual pixels, allowing the glow of different combinations of colors. The viewer is usually not aware of all changes, because his brain processes all information as a continuously moving image. Since the plasma TV screen contains quite a few pixels than standard television, the image is noticeably sharper. Each combination of pixels can reproduce a precise shade, not a rapid approximation. This means that colors are usually deeper and richer.
The main disadvantage of the TV system is vulnerability to damage. If the hard object hits the screen, hundreds of individual gas -filled pipes immediately lose their ability to shine. Replacing all these elements is a time -consuming and expensive process if it can be at all. Plasma TV ownersSystems should always consider the purchase of insurance and extended guarantees, as the most common repair seems to be a complete screen replacement. Because plasma -generating gas can escape or less reactive on electric charges, plasma TV systems have a limited durability. It may take several years before a noticeable change in image quality, but the cumulative effects are similar to what is happening in the neon, and the fluorescent lighting-the gas inside the tube begins to flash instead of still burning.
