ABSTRACT:
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.
