Abstract: In a fluorescent display tube provided with a plurality of electrically isolated grids, spacings for electrically isolating the grids are arranged to divide portions of an anode to be integrally displayed.

Abstract: 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.A gas discharge occurs at each intersection of the first electrodes supplied with the full bipolar pulse wave and the grounded second electrodes. In accordance with one aspect of the present invention, production of the driving pulses may be suspended either by a preselected one of the first and second selection signals or by coincidence logic operating upon preselected first or second selection signals.
