Abstract
A gas discharge panel self shift drive system is disclosed in which shift electrodes connected to and energized by voltages supplied to a plurality of shift buses, and electrodes connected to a common bus are disposed to intersect each other at right angles with an ionizable gas filled discharge space being defined therebetween. A shift voltage is applied in succession to the plurality of shift buses to shift a discharge spot. In this system, a high voltage pulse of an erasing level is applied to the common bus; a low voltage pulse is applied to the shift buses; and a sustain voltage which is the sum of the high and low voltages is applied to discharge cells at the intersecting points of the shift electrodes and the common electrodes to sequentially shift the discharge spot.
