Patent ID: 8093818

Claim:
A plasma display device comprising: a plasma display panel (PDP) having a first electrode; a temperature detector for detecting a temperature of the PDP; a driver for applying a driving voltage to the first electrode; and a controller for generating a control signal to control the driver according to the temperature detected by the temperature detector, wherein the driver comprises: a first transistor coupled between the first electrode and a first power source for supplying a scan voltage to the first electrode; at least one first resistor coupled between the first electrode and a control electrode of the first transistor; at least one second resistor coupled between the control electrode of the first transistor and the first power source; and a second transistor coupled between the first transistor and the first power source, the second transistor being adapted to gradually decrease a voltage of the first electrode to a reset minimum voltage when the second transistor is turned on during a reset period, wherein at least one of the first resistor or the second resistor is a variable resistor having a resistance that varies according to the control signal of the controller, and wherein the controller is configured to set resistances of the at least one of the first resistor or the second resistor to control a voltage difference between the reset minimum voltage and the scan voltage to be approximately equal to a first voltage when the temperature of the PDP is less than a reference temperature, and to set the resistances of the at least one of the first resistor or the second resistor to control the voltage difference between the reset minimum voltage and the scan voltage to be approximately equal to a second voltage that is greater than the first voltage when the temperature of the PDP is greater than the reference temperature.
