Abstract
In an alternate type plasma panel, the low voltage/high voltage interface circuits of the integrated circuits associated to the second network of electrodes are supplied in high voltage by the two amplifiers associated to each of these integrated circuits. During elaboration of the writing and erasure signals, one of the amplifiers supplies the voltage to be applied to the selected electrodes, to write or to erase, while the other amplifier supplies the voltage to be applied to the non selected electrodes.
