Abstract
The present invention relates to a method for regenerating microtips of a flat display screen including a cathode with electronic emission microtips associated with a grid for extracting electrons emitted by the microtips, wherein the microtips are made to emit under a current density which is substantially higher than a nominal operating current density and for a duration which is substantially higher than a nominal operating addressing duration.
