Patent ID: 7768479

Claim:
Control device for a plasma display panel designed to generate a same voltage rising edge or a same voltage falling edge simultaneously on a sustain electrode and on an address-sustain electrode of a cell of said plasma display panel, the voltage generated going, during said rising or falling edge, from an initial value to a final voltage value, power recovery circuitry being connected between said sustain electrode and said address-sustain electrode in order to recover power during the sustain phase of the discharges in the display cells, wherein said control device comprises first circuitry for taking the voltage of one of said sustain electrode and said address-sustain electrode from the initial voltage value to the final value of a positive polarity, said first circuitry cooperating with the power recovery circuitry in order to simultaneously bring the other voltage of said sustain electrode and said address-sustain electrode to said final voltage value of the positive polarity.
