Abstract

Abstract A binary addressable magnetically multiplexed system for selectively supplying discharge conditioning and discharge manipulating pulse potentials to row-column conductor pairs of a multiple gaseous discharge display/memory panel having a rowcolumn conductor display/memory matrix wherein the conductors are non-conductively coupled to the gaseous medium in the panel. The panel discharge manipulation system is characterized by plurality of transformers, preferably of the printed circuit type wherein all of the windings of a set are printed on flexible board sheets and are the primary and secondary windings are layered. The transformers for selected groups of the row and column conductors, respectively are thereby magnetically coupled to multiple secondary windings which are electrically connected to the row and column conductors in the panel matrix. The system is further characterized by means for pulsing the primary windings including binary logic circuit means and means for selectively energizing select ones of the primary windings and their multiple secondary windings.
