Abstract: According to the present invention, drive voltage pulses are applied between a pair of electrodes by driving a first power source having a specific voltage from a state in which the electrodes are maintained at the potential of a reference power source that is different from the potential of the ground power source, and then returning it to the reference power source. As a result, the gas discharge current or capacitance charging and discharging current accompanying the application of the drive voltage pulses is prevented from flowing to the first power source line. The above-mentioned gas discharge current or capacitance charging and discharging current resulting from the application of the drive voltage pulses flows to the first power source or the reference power source electrically separated from the ground power source, and does not flow to the ground power source line, so no noise is generated on the first power source.

Abstract: A flat display apparatus comprises a flat display panel in which at least some of display electrodes are formed from a scan electrode and an address electrode arranged so as to intersect each other, and has a characteristic such that as the amount of driving load of the flat display panel increases, the activation energy of discharge gas increases and the panel driving voltage decreases. In a driving method for the flat display apparatus, when the amount of driving load of the flat display panel increases (S1 to S4), the driving voltage of the scanning electrode or the driving voltage (Vd) of the address electrode is reduced.
