Abstract:
A driving method of an m.times.n plasma display panel having m pairs of scan electrodes having m sustaining electrodes Y1,. Y2, . . . , Ym and m common electrodes X1, X2, . . . , Xm which are arranged alternately and in parallel, and n data electrodes arranged to be orthogonal with respect to the m pairs of scan electrodes, where while the sustaining electrodes Y1, Y2, . . . , Ym are divided into i groups of electrodes and electrodes in each group are connected to a common line to form i groups of commonly connected Y electrodes. YY1, YY2, . . . , YYi, and the common electrodes X1, X2, . . . , Xm are divided into j groups of electrodes and electrodes in each group are connected to a common line to form j groups of commonly connected X electrodes, XX1, XX2, . . . , XXj, the scan electrodes are connected so that when two groups are selected respectively from the i groups of commonly connected Y electrodes, YY1, YY2, . . . , YYi, and the j groups of commonly connected X electrodes, XX1, XX2, . . . , XXj, only one pair of an X electrode and an Y electrode, which is adjacent to the X electrode, is selected, wherein the driving method includes:an initialization step of completely erasing a wall charge created at subfield during a previous step; andan address discharge step of selecting and priming a pixel corresponding to image information,wherein the address discharge step includes steps of:impressing sequentially to the groups of commonly connected X electrodes first pulses having an amplitude of a second voltage with reference to a first voltage of a reference voltage impressed to the scan electrodes, and a width smaller than that of driving signal pulses of the data electrodes; andimpressing sequentially to the groups of commonly connected Y electrodes second pulses having an amplitude of a third voltage having a polarity opposite to that of the second voltage with reference to a first voltage and a width of a period for which the first pulses are impressed once respectively to all the groups of commonly connected X electrodes.
