Abstract:
1. Method for processing data of a picture to be displayed on a display panel with persistent luminous elements during a frame comprising a plurality of subfields, each subfield comprising an addressing phase during which the luminous elements of the panel are activated or not in accordance with the picture data and a sustain phase during which the activated luminous elements are illuminated by sustain pulses, wherein it 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, for a current frame and a plurality of frames preceding said current frame, the maximal line load difference between two consecutive lines of the display panel, and selecting, for each subfield, a sustain frequency reduced in accordance with its maximal load difference in order to reduce line load effect.
