A driving circuit for a gas discharge panel having X electrode rows and Y electrode columns arranged in a matrix has its X electrode driver comprising first up drive circuit (XU1, XU2, ...) used both for applying a discharge sustaining voltage and a write-in voltage to the X electrodes X11, X12, ...). Also, the Y electrode driver preferably comprises a second up drive circuit (YU1, YU2) for applying a discharge sustaining voltage to the Y electrodes (Y11, Y12, . . .) a second down drive circuit (YD1, YD2), for grounding the second up drive circuit (YU1, YU2) when the discharge sustaining voltage is not applied to the Y electrodes (Y11, Y12, ...) a write-in driver (YW1, YW2, ...) for applying a write-in voltage to the Y electrodes (Y11, Y12, ...) and a clamping circuit (YC1, YC2) for grounding the Y electrodes (Y11, Y12, . . .) when the write-in voltage is not applied to the Y electrodes (Y11, Y12, ...). This arrangement of the driving circuit leads to a considerable decrease in the number of circuit elements required to implement the driving circuit. |
