ABSTRACT:
An improved drive scheme for a plasma display panel having a cell formed at the crossover point of each of the panel's column and segment electrodes and a control system for implementing this drive scheme. The drive scheme of the present invention comprises the simultaneous application of AC drive signals having positive and negative components to the column and segment electrodes associated with a designated cell of the panel. These drive signals are 180.degree. out-of-phase and are arranged to produce across the designated cell a voltage swing of sufficient magnitude to produce a discharge therein. In one embodiment of the drive scheme, the positive and negative components of each drive signal are equal. In a second embodiment of the drive scheme, the positive and negative components of each drive signal are not equal.
The control system for implementing the drive scheme is comprised of a DC-to-AC converter for producing the AC drive signals, a driver circuit associated with each column electrode of the display panel and a driver circuit associated with each segment electrode of the display panel. Each of the column and segment driver circuits is operable to provide to its associated column or segment electrodes both of the components of its associated AC drive signal if it is selected or only one of the components of its associated drive signal if it is not selected. In this way, the positive and negative components of the AC drive signals are selectively applied to the panel's column and segment electrodes to produce a desired illumination pattern.
