Plasma display panel driving circuit including apparatus for producing high frequency pulses without the use of clock pulses

摘要

In a circuit for driving a plasma display panel, a blocking oscillator produces pulses varying between a positive and a negative voltage. Transistors controlled by first selection signals selectively supply first electrodes of the panel with either the complete bipolar pulses, or with only a predetermined one of the positive or negative pulse components. Further transistor switches controlled by second selection signals selectively connect and disconnect second display panel electrodes to ground. A constant voltage is applied to the disconnected second electrodes.
