Abstract
An improved driving system and method for shifting a discharge spot from a given discharge cell to an adjacent discharge cell in an A.C. gas discharge, or plasma display, panel, having opposed sets of electrodes respectively covered with corresponding dielectric layers thereby insulated from the discharge gas space. One set of electrodes comprises common electrodes extending in parallel relationship and defining the direction of propagation of the shifted discharge spots. The other set of electrodes, spaced apart from the first set by the gas space, extends in parallel relation transversely to the first common electrodes, and comprise the shift electrodes. The shift electrodes are arranged in groups of a predetermined number in each group and a corresponding number of buses permits selective application of shift pulses to the respectively associated shift electrodes in sequence for each group and simultaneously for the successive groups. An improved operating margin for the shift function is achieved by utilizing the priming discharge effect of a given cell currently discharging, to reduce the necessary firing voltage at an adjacent discharge cell to which the current discharge spo…
