PROBLEM TO BE SOLVED: To provide a plasma display device which reduces luminance of sub-fields having smaller weights to improve representation of lower gray scale. SOLUTION: Only some row electrodes are addressed in a subfield having the smallest weight to reduce the luminance of the subfield having the smallest weight. For example, only odd-numbered row electrodes are addressed in an odd-numbered frame and only even-numbered row electrodes are addressed in an even-numbered frame in the address period of the subfield with the smallest weight. The length of the sustain period of a subfield having the next smallest weight is identical to the length of the sustain period of the subfield having the smallest weight. Then, the ratio of the luminance of the two subfields is increased by twice to improve representation of lower gray scale. COPYRIGHT: (C)2006,JPO&NCIPI
