Abstract

An improved driving system for write operations into shift rows in a multi-row self shift type gas discharge panel. Each shift row is composed of at least one shift channel comprising a regular arrangement of plural shift discharge cells and which is provided with a write electrode which defines a write discharge cell at one end of the shift channel. To the write electrodes of the shift rows, the write voltage pulse is supplied in common. When applying the write voltage pulse to the write electrode of a selected shift row, a shift voltage pulse which is the same in polarity as said write voltage pulse and has an equivalent or greater time width than said write voltage pulse is applied to the shift electrode opposing the write electrodes of the non-selected shift rows, and as a result, erroneous discharges, namely, over-write to the adjacent shift discharge cells, can be avoided by preventing the discharge of the write discharge cells of the non-selected shift rows.
