The xenon and neon gas in a plasma television is contained in hundreds of thousands of tiny cells positioned between two plates of glass. Long [[electrodes]] are also sandwiched between the glass plates, on both sides of the cells. The address electrodes sit behind the cells, along the rear glass plate. The transparent display electrodes, which are surrounded by an insulating dielectric material and covered by a magnesium oxide protective layer, are mounted above the cell, along the front glass plate. |

In a monochome plasma panel, control circuitry charges the electrodes that cross paths at a cell, causing the plasma to [[ion]]ize and emit photons between the electrodes. The ionizing state can be maintained by applying a low-level voltage between all the horizontal and vertical electrodes - even after the ionizing voltage is removed. To erase a cell all voltage is removed from a pair of electrodes. This type of panel has inherent memory and does not use phosphors. A small amount of nitrogen is added to the neon to increase [[hysteresis]]. |

To ionize the gas in a color panel, the plasma display's computer charges the electrodes that intersect at that cell thousands of times in a small fraction of a second, charging each cell in turn. When the intersecting electrodes are charged (with a voltage difference between them), an electric current flows through the gas in the cell. The current creates a rapid flow of charged particles, which stimulates the gas [[atom]]s to release [[ultraviolet]] photons. |

The phosphors in a plasma display give off colored light when they are excited. Every [[pixel]] is made up of three separate subpixel cells, each with different colored phosphors. One subpixel has a red light phosphor, one subpixel has a green light phosphor and one subpixel has a blue light phosphor. These colors blend together to create the overall color of the pixel. By varying the pulses of current flowing through the different cells, the control system can increase or decrease the intensity of each subpixel color to create hundreds of different combinations of red, green and blue. In this way, the control system can produce colors across the entire [[visible spectrum]]. Plasma displays use the same phosphors as CRTs, accounting for the extremely accurate color reproduction. |

Tampilan plasma adalah sebuah tampilan layar datar emisif di mana cahaya dihasilkan oleh phosphor yang tereksitasi oleh sebuah pelepasan muatan plasma antara dua layar datar gelas. Gas yang dilepas muatannya tidak mengandung merkuri (berlawanan dengan AMLCD); sebuah campuran gas mulia (neon dan xenon) digunakan. Campuran gas ini sulit bereaksi dan sama sekali tidak berbahaya.
