Abstract
Focusing attention on a new fact that a difference in the operating margin between sub-fields becomes remarkable when preliminary discharge is not provided for all sub-fields, but is thinned out, the operating margin for a plasma display panel will be improved by restricting the difference in the operating margin. In the case of the thinned preliminary discharge system, particularly the dependence of maintenance blanking characteristics on the maintenance pulse number becomes remarkable and as a result, the operating margin difference among the sub-fields becomes remarkable, and therefore, parameters for blanking pulse of the sub-field during the maintenance blanking period are set in conformity with the maintenance pulse number (number of times of emission) for each sub-field in order to restrain this operating margin difference.
