Abstract (en)

The present invention relates to a method of addressing a memory-effect display panel comprising cells defined at the intersection of arrays of crossed electrodes, the cells having two states, one being the "written" state and the other the "erased" state, the method consisting, over a given cycle time, in applying a sustain signal to all the cells, the sustain signal producing a sustain discharge in the cells in the written state, and in applying an address signal, comprising a semi-selective signal and a selective signal, in succession to the electrodes of one array, the semi-selective signal being applied simultaneously to different electrodes for at least part of the cycle time of the selective signal. The invention applies to coplanar-type and matrix-type AC plasma display panels. <IMAGE>
