Abstract
The method of the invention generates an address signal for addressing columns or rows of a PDP. In the case of addressing a column, for example, the method comprises the following steps. For a phase T, a DC voltage Vis applied across the terminals of a solenoid L, so that the latter stores energy, and applies a voltage A across the terminals of a selected column. During a phase T, some of the energy stored in the solenoid L is discharged into the column until the voltage across the terminals of the column becomes about zero. During a phase T, an approximately zero voltage is maintained across the terminals of the column. According to one embodiment the selection of the column(s) during this phase is modifiable. During a phase T, the solenoid L is charged with current stored in a capacitor until the voltage across the terminals of the column is zero.
