Plasma display
Plasma screens are made of two sheets of glass with two gases stored between the sheets. The gases are xenon and neon and they fill thousands of tiny chambers, or spaces. Behind each space are a series of red, blue and green phosphors that give off light when struck by radiation. When electricity connects to the plasma chambers the colored phosphors produce the right color on your screen. They work in a very similar way to fluorescent lamps used for lighting.
