ABSTRACT:
This invention provides a drive method and an drive apparatus for a display panel that continuously maintain good image quality when the display panel is used for a long period of time. Based on the image data that are output from the A/D converter, an APL (Average Picture Level) calculation unit calculates the average brightness level for one field, and then a total light emission calculation unit uses the APL calculates the total number of times light is emitted. Based on the total light emissions or the total usage time, the control unit controls the voltage of drive pulses for the X-sustain driver and Y-sustain driver, or the timing at which they are applied, in order to compensate for changes over time of the PDP.
