Title: Two-dimensional model of an AC plasma display panel cell in a neon-xenon mixture

Abstract

We present a 2-D fluid model of an AC plasma display panel cell. Plasma Display Panels (PDP) are flat display devices where the light of each picture element is emitted from a plasma created by an electric discharge. In the simplest electrode configuration, AC plasma display panels consist of two glass plates, each with parallel electrodes deposited on their surfaces. The electrodes are covered with a dielectric film above which a protective MgO layer is deposited. The plates are sealed together with their electrodes at right angles, and the cap between the plates is filled with a rare gas mixture. An electric discharge can be initiated in the gas cap by applying a voltage pulse between a line electrode and a column electrode. This discharge is transient due to the dielectric layers covering the electrode: the charges deposited on the dielectric surfaces induce in the gas cap a voltage which opposes the electrode voltage. Since the electrode voltage is AC (frequency in the 10-100 kHz range), a discharge is initiated each time the electrode voltage changes sign (the voltage across the dielectric layers adds to the electrode voltage when it changes sign). The {open_quotes}ON{close_quotes} state of a picture element ismore » therefore a succession of transient discharges. In color displays, the UV light of the discharge is used to excite phosphors in the three fundamental colors (at least three discharge cells are used for one pixel of the screen). Neon-xenon or helium-xenon mixtures are generally used in color displays where photons emitted by excited atomic (147 nm) and molecular (150 nm and 173 nm) xenon are used to excite the phosphors.« less
