METHOD FOR DRIVING PLASMA DISPLAY PANEL AND PLASMA DISPLAY DEVICE, ESPECIALLY PREVENTING ERRONEOUS OPERATION BY CHANGING SLOPE OF RISING PERIOD OR FALLING PERIOD

摘要

PURPOSE: A method for driving a plasma display panel and a plasma display device are provided to prevent the erroneous operation due to the reduction of the secondary emission coefficient in response to the external temperature reduction by changing the slope of the rising period or the falling period. CONSTITUTION: A plasma display device includes a plasma display panel(400), an external temperature sensor(100), a logic circuit(200) and a driving circuit(300). The plasma display panel is provided with a plurality of address electrodes, a plurality of sustain electrode and a plurality of scan electrodes. The external temperature sensor measures the external temperature of the plasma display panel. The logic circuit has the slope data values of the lamp voltage falling during the reset period in response to the external temperature value measured by the external temperature sensor. And, the driving circuit drives the plasma display panel in response to the slope data value of the changed lamp voltage transmitted from the logic circuit.
