摘要： A driver for a plasma display panel having a plurality of scan electrodes which are independent of each other, comprising: a plurality of driver circuits provided between a first power supply line (FLG) and a second power supply line (FVH), and connected to the scan electrodes, respectively; a first power supply circuit (71) including a first voltage generator (73) and a second voltage generator (72), wherein the first voltage generator (73) supplies OFF voltage to the first power supply line (FLG) and the second voltage generator (72) supplies ON voltage (Vsc) to the second power supply line (FVH), for writing display data; and a second power supply circuit (90) charging the first and the second power supply lines (FLG,FVH) to a defined value (Vs) for causing discharges based on the display data. To reduce the required withstand voltage of the scan electrodes, each of the scan electrodes is grounded for a short period via the first voltage generator prior to applying the defined value (Vs) of voltage during a sustain discharge period.
