摘要： A driving method of a plasma display panel having a display electrodes arranged at the ratio of three per two rows is provided, in which all rows are lighted in sustaining period from an addressing period to the next addressing period and electromagnetic interference is reduced sufficiently. A display discharge is generated by controlling potentials of the display electrodes so as to satisfy two conditions. One condition is that there is a pair of display electrodes having terminals at the same side of the display screen and current directions opposite to each other. Another condition is to generate a potential difference across the display electrodes, which is necessary for discharging. Magnetic fields are canceled by each other in the pair of electrodes having current directions opposite to each other, so that electromagnetic interference is reduced.

摘要： A plasma display panel and a method of driving the same are provided in which circuit elements necessary for controlling potentials of scan electrodes can be reduced without using a complicated multilayered wiring. In the plasma display panel, k (k≧2) data electrodes, each of which is continuous from one end of a column to the other end, are arranged for each column of a matrix display. All scan electrodes in a display screen are classified into k groups, and one of k groups is assigned to k data electrodes in each column. Each data electrode is crossed with or opposed to scan electrodes belonging to the group that is assigned to the data electrode without overlapping a partition in a plan view and is crossed with or opposed to other scan electrodes with overlapping the partition.
