Abstract:
A drive system for an AC plasma display panel having pixel elements located by column (X) and row (Y) electrodes, X electrode driver means connected to the X electrodes and Y driver means connected to the Y electrodes and a source of N-bit word signals representing the amplitude of video signals for each pixel element located by the crossing of said X and Y electrodes and means for translating said N-bit word to driver signals for controlling the X and Y driver means to cause each pixel element to selectively emit light, a first voltage driver means connected between the output storage elements and said X electrode for supplying X axis control voltage to said column X electrodes, said first voltage driver means being dedicated solely to high speed pixel control which is logic ground based and a second voltage driver means connected between said output storage elements and said row (Y) electrodes for supplying Y axis control voltages to said row electrodes, said X axis control voltages being applied to said column (X) electrodes at selected times to selectively cancel said Y axis control voltage,wherein there are write, erase and sustain sequences for said pixels; andwherein said second voltage driver means supplies the row (Y) electrodes with all of the drive voltage for the non-selective write, erase, and sustain sequences, while the first voltage driver means applies axis as control voltage only to said column (X) electrodes at selected time to cancel, write or erase the Y axis drive control voltages.
