Abstract (en)
The present invention relates to a method for processing data of a picture to be displayed on a display panel with persistent luminous elements in order to reduce load effect in said display means. The method comprises the following steps : computing, for each subfield, the amount of activated luminous elements in each line of luminous elements of the display panel, called line load, calculating, for each subfield, the maximal difference of line loads of two consecutive lines of the display panel, and selecting, for each subfield, a sustain frequency in accordance with its maximal load difference in order to reduce line load effect. <IMAGE> <IMAGE> <IMAGE>
