ABSTRACT:
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 luminancef) then, mapping luminance codes to the output sub-field codes.The method is used in plasma display panels (PDP).
