摘要： The total number of the scan electrodes is divided into a first scan electrode group and a second scan electrode group. The first scan electrode group drive section for driving the first scan electrode group produces a selection potential and a non-selection potential in the scan period, and supplies scan pulses based on the two potentials in the first half of the scan period. The complex switch section supplies the selection potential produced using the first scan electrode group drive section to the second scan electrode group drive section for driving the second scan electrode group in the latter half of the scan period. The second scan electrode group drive section supplies scan pulses based on the input selection potential.

The present invention provides the sub-field in which the cycle of each of the first and second sustain pulses is longer than 5.5 μs within such a range that a time of the sustain period does not exceed Tw×(N−1)/N, where N denotes the number of display electrode pair groups, and Tw denotes a time necessary for carrying out the address process with respect to the discharge cells corresponding to all the display electrode pairs.
