Abstract
Provided is a device for supplying an array of electrodes of a plasma display panel, the device including, for each electrode, a driver having a series of switches and a series of diodes, the common points of which are connected to the electrode. The upper terminal of the series of diodes is connected directly to the output of a sustain generator and the lower terminal is connected to the sustain generator via a power switch. One of the terminals of the series of switches is connected to the output of a negative voltage generator. In periods during which the negative voltage generator applies a negative voltage to the electrodes, the power switch is open in order to avoid a short-circuit via the diode of the sustain generator.
