ABSTRACT:
The present invention relates to a method for processing video signals for display on a display panel comprising a matrix array of cells which could only be “ON” or “OFF”, wherein the time duration of a video field is divided into N sub-fields during which the cells can be activated, each sub-field comprising at least an addressing period and a sustaining period, the duration of which corresponding to the weight associated with said sub-field, said method comprising at least a priming period, characterized in that the position of the priming period is determined as follows:determination of a sustain threshold value D for a given addressing speed and panel technology,calculation of the number of sustain pulses in each sub-field n, n being such that 1≦n≦N,if the number of sustain pulses is above or equal to D, addition of a priming pulse before at least the sub-field n+1.This method is mainly applicable to plasma display panel.
