Abstract (en)
The present invention relates to a method for compensating load effect in a display panel with persistent luminous elements. The method comprises the following steps : encoding the picture data into subfield data, calculating the load of each subfield on the basis of said subfield data, and adjusting the number of sustain pulses of each subfield on the basis of its load in order to have a relation of proportionality between the luminance produced by the persistent luminous elements for the subfield and its weight. <IMAGE>
