ABSTRACT:
Methods and systems for driving a self-shift type of gas discharge panel utilize a plurality of basic pulse trains for the shifting of discharge spots. The pulse trains are applied cyclically and sequentially to each phase of a multi-phase display cell array, each cycle comprising several unit periods, and the array having regularity in its arrangement. This facilitates control of timing for phase switching, and accurate shift operation can be realized by variation of the basic pulse trains.
