Abstract:
1. An apparatus for controlling address power of a plasma display panel, the plasma display panel having pluralities of address electrodes, scan electrodes, and sustain electrodes, the scan electrodes and sustain electrodes forming pairs and being alternately disposed on the plasma display panel, the apparatus comprising: a memory for storing sustain discharging information with respect to load ratios; an address power controller responsive to an externally input video signal for calculating a sum of pixel differences between lines of the externally input video signal and for outputting video data modified by multiplying the video signal with an attenuation coefficient corresponding to the calculated sum; a video data processor for processing the modified video data; an average signal lever detector for measuring a load ratio of the modified video data; and a sustain power controller for outputting sustain discharge information corresponding to a load ratio of currently input data.
