Step1: Address electrode causes gas to change to plasma state

Step2: Gas in plasma state react with phosphors in disc charge region

Step3: Reaction causes each subpixel to produce red, green,
blue light

Plasma

By using different voltages between the display and address electrodes, the air inside the tube will change to a plasma state and emit electrons that try to leave the tube and get past the phosphors covering the tube ends.

Once electrons impact the phosphors, they will generate a specific color depending on the component colors they activate. The picture below shows only one sub-pixel in a plasma TV. Actually, they require three sub-pixels per pixel to create all varieties of color.
