Abstract
A drive system is shown for AC plasma (ACP) gas discharge flat bistable matrix panels on which real-time video and computer graphics, both with pixel by pixel gray scale are displayed. The drive scheme increases scan speed, reduces complexity, and minimizes the circuitry required to operate the video and computer graphics on the ACP display by a unique application of standard high density memory IC architecture and panel drive waveform technique applying all of the drive voltages to the ACP panel from the row (Y) axis and only selective cancellation voltage from the column (x) axis.
