Abstract
A method and apparatus to automatically control power of address data in a PDP includes a plurality of address electrodes, a plurality of scan electrodes, and a plurality of sustain electrodes arranged in pairs with the scan electrodes, and a PDP including the apparatus. The sum of pixel value differences between adjacent ones of successive lines in input image data is calculated, and an address power control (APC) level corresponding to the calculated line pixel value difference sum is determined. The image data is then repeatedly multiplied by a gain initially corresponding to the start gain and sequentially decremented by a predetermined value from the start gain upon every multiplication until the gain corresponds to the end gain, to output corrected address data.
