<p>The present invention relates to a method for improving grey scale fidelity portrayal of pictures displayed on matrix display screens. The method comprises the following steps : a) for a given peak white level, distributing the sustain pulses among the sub-fields, the number of pulses corresponding to the sub-field weighting, b) mapping the sub-field codes to luminance codes, c) re-ordering luminance codes in a definite order, d) mapping the video levels to the available luminance codes, e) processing the video levels to achieve intermediate levels of luminance f) then, mapping luminance codes to the output sub-field codes. <??>The method is used in plasma display panels (PDP). <IMAGE></p> |
