ABSTRACT:
An AC drive discharge type display apparatus which includes a display panel having groups of transverse electrodes and vertical electrodes which are positioned in cross form with a gap therebetween and having cross points which are made luminescent by applying an AC sustaining drive voltage, a turn-on signal and a turn-off signal. A drive circuit is further provided and has transistors and resistances which are connected at one end to the collector electrode of the transistor and the other end of the resistor being disposed in a matrix; means for commonly connecting said other ends of the resistors in each transverse line of the matrix; a first selective switch circuit for applying the turn-on signal or the turn-off signal by selectively driving the transverse lines which are commonly connected; means for commonly connecting the bases and emitters of the transistors in a vertical line of the matrix; means for connecting each of the bases and emitters which are commonly connected, through a diode to the sustaining drive voltage source; a second selective switch circuit for selectively driving the vertical lines by connecting the same to the bases or emitters which are commonly connected; and wherein the collectors of the transistors of the drive circuit are connected to the electrodes in one or both of the groups of the electrodes in the transverse or vertical direction of the display panel.
