Plasma Display

We all want to have a Flat screen, large size TV hanging in our living room. These flat screen televisions use either the LCD display or the Plasma display technology. I have already talked about the LCD display in my last post. Here I will stress on the Plasma display.
A plasma display consist of two glass panels holding an inert(that is, the gases do not react) mixture of noble gases(neon and xenon). These gases are exited by electricity converting them into plasma(ionized gas). This plasma then excites the phosphors to emit light which in turn lights up the pixels.
The pixel is a point which make up the entire screen. This pixel is in turn divided into a three subpixels. In a Plasma screen each subpixel can produce millions of colors. With the combination of all such pixels we get the so-called perfect picture quality.
