The deterioration of the quality of moving pictures caused by dynamic false contours is a serious obstacle to obtaining a satisfactory picture quality from PDPs(Plasma Display Panels). The false contour arises from sub-field method used to represent the gray scale. We propose a combination of two techniques time-compressed diving and weight division for the upper bits. Each of the two techniques has different role in improving the quality. We also outline a technique for reducing the frequency with which false contours appear, and techniques for driving large panels which have more than 1000 cathode lines. The effect of the methods is evaluated both by computer simulation and subjectively. The result shows that these methods significantly improve the quality of the moving picture on a PDP HDTV display.
