Lcd Vs Plasma Tvs

Is Plasma TV Dead?





Instead of using a backlight and a set of filters to illuminate pixels on the screen, images on a plasma TVs are created by ionized gas (plasma) that lights up when you run an electrical current through it. The easiest way to undertand it is by thinking of each individual subpixel on the TV as a tiny neon light, or perhaps a miniature version of the florescent tubes you might be sitting under right now. The pixels that make up a plasma display are almost exactly the same technology, just on a much smaller scale. Anatomy of a plasma TV subpixel For those of you who care to understand the science behind it all, heres how the magic happens: An electrode applies an electrical current to a small cell filled with a noble gas mixture (usually neon and xenon). This excites the gas, ionizing it and transforming it into a plasma. This plasma emits ultraviolet light which we cant see but when the UV light hits a phosphor coating that lines each cell, it causes the phosphor to glow and put out light that we can see.
