ABSTRACT:
A system for operating a memory display panel comprising a gas-filled envelope having an array of D.C. gas discharge cells and an array of quasi A.C. gas discharge cells, there being one A.C. cell for each D.C. cell. The A.C. cells are the display cells of the panel and include electrode means which receive sustainer signals for sustaining glow therein, and the D.C. cells are operated in a scanning fashion to address selected A.C. cells in which glow is to be displayed.
The system includes electronic circuitry for performing the above-mentioned operations of driving the D.C. cells, generating sustaining signals for the A.C. cells, and energizing the A.C. cells in accordance with input data information. Appropriate timing control circuits are also provided.
