Abstract
A control circuit is provided for an alternating type plasma display panel, comprising integrated circuits which are used for the first and second electrode arrays of the panel. In the first array, the integrated circuits participate in producing selective signals and transmit the reference voltage of the sustaining signals. In the second array, the integrated circuits participate in producing selective signals, and transmit the square wave voltage of the sustaining signals and their reference voltage is floating, that is to say that it follows the sustaining signals and, during production of the selective signals, it follows the lowest potential that is possible to apply to the electrodes. The integrated circuits are provided with logic circuits which receive a signal indicating whether the integrated circuit is used with the first or with the second electrode arrays, so that in the case of use with the first array the active electrodes are brought to the high level with respect to the non active electrode and in the case of use with the second array the non active electrodes are brought to the high level with respect to the active electrodes.
