Patent ID: 7450089

Claim:
A plasma display panel that receives external video data and displays gray scales through dual scanning, comprising: a plasma panel including a plurality of address electrodes, a plurality of scan electrodes, and a plurality of sustain electrodes; a temperature sensor for sensing a temperature of the plasma panel; a controller that receives video data to generate an address electrode driving signal, a sustain electrode driving signal, and a scan electrode driving signal, the controller controlling a scanning direction to be changed to scan the plasma panel from both ends to the center of the panel and rearranging the address electrode driving signal to correspond to the controlled scanning direction when the temperature sensed by the temperature sensor is lower than a first temperature; an address electrode driver that applies a voltage corresponding to the address electrode driving signal to the address electrodes; a sustain electrode driver that applies a sustain voltage to the sustain electrodes in response to the sustain electrode driving signal of the controller; and a scan electrode driver that determines a scanning direction according to a control signal of the controller and applies a voltage to the scan electrodes in response to the scan electrode driving signal.
