Abstract
To generate a rising or falling edge simultaneously on the electrodes Ys and Ysa of a plasma display cell, the invention provides for the use of the power recovery circuit of the control device in order to apply, to one of the electrodes Yas and Y, the rising edge applied to the other of the electrodes by a dedicated circuit.
Claims4
Control device for a plasma display panel designed to generate a voltage rising or falling edge simultaneously on a sustain electrode and on an address-sustain electrode of a cell of the said plasma display panel, the voltage generated going, during the said rising or falling edge, from an initial value to a final value, power recovery means being connected between the said sustain electrode and an address-sustain electrode in order to recover power during the sustain phase of the discharges in the display cells, wherein it comprises first means for taking the voltage of one of the said sustain electrode and address-sustain electrode from the initial value to the final value, the said first means cooperating with the power recovery means in order to simultaneously bring the other of the said sustain electrode and address-sustain electrode to the final voltage.
