A Scan driver (100) of a plasma display panel employs a scan voltage supply circuit (108) having an input (N2) and an output (N3), the voltage circuit configured for supplying a negative voltage (-Vy) for a scan electrode. The plasma display panel also employs a power supply (Vy) that has a positive terminal and a negative terminal, where the negative terminal is connected to the input of the voltage circuit. The power supply is otherwise configured relative to the voltage circuit such that the positive terminal of the power supply is connected to the output of the set-up voltage supplier (104) during the set-up of the reset period, whereby the voltage difference between the output and the input of the scan voltage supply circuit (108) is fixed as a function of the power supply. By fixing this voltage difference, parasitic capacitance is minimized, power consumption and calorific value are reduced, and the plasma display panel operates in a more stable manner. |
