Abstract
A plasma display having a discharge cell, the emission efficiency of which is improved by generating first and second discharges with one sustaining pulse. A first discharge is generated by increasing a voltage up to a maximal value through a LC resonance formed by a recovery coil and a panel capacitor. A second discharge is generated by connecting the panel capacitor to a power supply when the voltage falls a predetermined amount below the maximal value, thereby increasing the voltage to a predetermined level above the maximal value.
