Abstract:
A method of driving a plasma display panel having first and second electrodes at least one of which is covered with a dielectric, said plasma display panel repeatedly producing a gas discharge in response to a pulse voltage of alternately changed polarities applied between said first and second electrodes, said method comprising the steps of:(a) charging a static capacitance element between said first and second electrodes through an inductor and storing energy in said inductor until the magnitude of current flowing through said inductor reaches a maximum value;(b) emitting said energy stored in said inductor toward said static capacitance element; and(c) charging said static capacitance element at a low impedance through a path which does not include said inductor in the course of the emission of said energy stored in said inductor toward said static capacitance element in addition to the emission, to supply a voltage corresponding to said pulse voltage to said static capacitance element,wherein the inductance value of said inductor is set so that a voltage-to-be-reached of said static capacitance element which is determined by a Q-value of a resonant LC circuit comprised of said inductor and said static capacitance element is higher than a gas discharge starting voltage and close to said pulse voltage if said static capacitance element is charged from said inductor but not through said path, andwherein said gas discharge starting voltage is a minimum voltage to be applied to said static capacitance element for production of said gas discharge.
