Abstract

The present invention relates to a method for processing video pictures for display on a display device comprising a plurality of lines constituted by luminous elements called cells corresponding to the pixels of a picture, wherein the time duration of a video frame is divided into a plurality of sub-field periods during which the cells can be activated for light emission, a sub-field period being divided into an addressing period wherein the plurality of lines is scanned line by line, a sustaining period and an erasing period, wherein, in the addressing period, the addressing time is different from one line to an other. The invention is mainly used in PDP technology.
