The present invention relates to a device for driving a plasma display panel having a plurality of cells arranged in rows and columns, said device comprising row address means for selectively addressing the display cell rows and creating, where required, in cooperation with means for selectively applying data voltages to the display columns, an electrical discharge inside the cell disposed at the intersection of the row and column selected during an address phase, and sustain means (I3, I4, I5, I6) for sustaining the electrical discharges inside said cell during a sustain phase immediately following the address phase. According to the invention, the row address means and/or the sustain means are capable of allowing a bi-directional current to flow in the display cells during the address and/or sustain phases. The capacitive and light-emission currents appearing during these phases can thus flow freely and do not create electromagnetic interference.
Device for driving a plasma display panel having a plurality of cells arranged in rows and columns, the rows of cells being distributed in a plurality of blocks of lines, said device comprising row address means for selectively addressing the display cell rows within the blocks and creating, where required, in cooperation with means for selectively applying data voltages to the display columns, an electrical discharge inside the cell disposed at the intersection of the row and column selected during an address phase, and sustain means for sustaining the electrical discharges inside said cell during a sustain phase immediately following the address phase, wherein said row address means comprise separate row address means for each said block of rows for addressing successively the blocks of rows by applying a first voltage to the cells of the selected block and a second voltage to the cells of the other blocks, said second voltage being greater than the first voltage, said separate row address means comprising:
