Dear Amy: Why are plasma displays only a few inches thick?
— Robert, Newcastle, Okla.

Dear Robert: A plasma display is thin because, unlike a traditional TV or computer monitor, it does not require the use of a glass tube to create an image. It has two layers of glass with plasma and two sets of electrodes between them. The plasma is made of positively charged xenon and neon atoms called ions. They are in thousands of tiny, phosphor-lined cells. Phosphors give off light when exposed to other light.

When electricity flows through the electrodes in front of and behind the cells, negatively charged particles called electrons enter the plasma. The electrons and ions attract each other, causing them to collide and release small amounts of ultraviolet light. The UV light causes the phosphors to emit visible light of green, red or blue color. Each pixel in a plasma display is composed of three cells, one each of green, red and blue. The intensity of the colors determines the color of the pixel.
