ABSTRACT:
When a plasma display panel driven by a conventional driving circuit therefor, spurious pulsed voltages appear across discharge cells which are in the vicinity of a selected discharge cell. A method and apparatus for driving a plasma display panel in a time division manner includes supplying the plasma display panel electrodes with suppress pulse trains for cancelling the spurious pulse voltages coupled thereto. The suppress pulse trains are in synchronism with, and of a polarity opposite to the driving pulses that are supplied to such electrodes in accordance with time division principles.
