In a plasma display, a drain of a first transistor is connected to a scan electrode, and a source of the first transistor is connected to a power source supplying a first voltage. First and the second resistors are connected in series with the scan electrode and the power source. A scan electrode driver turns on the first transistor during a reset period to decrease a voltage of the scan electrode. A scan electrode driver senses the voltage of the electrode from a voltage divided by first and second resistors connected in series between the electrode and the power source. Upon the voltage of the scan electrode becoming a second voltage which is higher than the first voltage, the scan electrode driver turns off the first transistor to maintain the voltage of the scan electrode at the second voltage. In an address period, a scan electrode driver supplies the first voltage to the scan electrode of a light emitting cell. At least one resistor of the first and second resistors is a variable resistor in which resistance varies as the temperature of the Plasma Display Panel (PDP) varies, such that the plasma display can perform steady operation. |
