Abstract
A time-voltage multiplexing system for addressing a particular cell or location on a gas discharge plasma panel in which a group of panel electrodes are charged to the cell voltage firing level but only one electrode of the group is allowed to remain charged for a time duration sufficient for selective discharging of the desired cell. A multiple secondary transformer embodiment incorporating the time-voltage multiplexing addressing system. A method and apparatus for increasing the usable range of sustaining signals for plasma panels by applying a narrow width boost pulse to the panel within a selected time immediately after the initiated sustaining discharge, including means for varying the boost pulse amplitude, width and position with respect to the sustaining discharge so that the usable sustaining signal range can be optimized for a particular plasma panel.
