(54)Improvements in video mode plasma panel displays


(57) 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.
