Abstract: An AC Plasma Display Panel is operated in a scanning mode using a conventional video data stream such as that applied to a cathode ray tube display terminal. A full line write followed by a selective erase technique is employed for image generation on a line by line basis. By eliminating the non-selective write signal used in normal plasma display operation, the duration of the sustain signal is substantially decreased and the write, erase and sustain functions are provided at a nominal 40 KHz rate.

Abstract: @ An A.C. Plasma Display Panel is operated in a video mode using the same signal train as applied to a conventional cathode ray tube terminal. For character generation, a selective erase technique is employed in which all cells in a raster line are energised and then selectively erased in accordance with the video data to be displayed. To facilitate the erase operation, a line of cells in close proximity to the scan line being selectively erased is employed to provide adequate and uniform priming for the erase operation, and is synchronised to maintain its position with respect to the line being erased. A short plasma erase signal is utilised to fit within the scan rate of the display. The invention is also applicable to character generation in block or multi-line mode.
