    "abstract": "The deterioration of the picture quality of displayed moving pictures caused by dynamic false contour artifacts is a serious impediment to obtaining good picture quality on PDPs (plasma display panels). The artifacts arise from the sub-field method used to represent the grayscale. We propose a combination of two methods, time-compression of emission and weighted division of upper signal bits, to improve picture quality. Each technique has a separate and important role in the improvement of quality. We also propose an additional technique for reducing the frequency with which the artifacts appear. The proposed methods were evaluated by computer simulation and subjective testing. The results showed that these methods significantly improved the moving picture quality of a PDP and provided a picture of acceptable quality for viewing on an HDTV receiver. A high-quality 42-in.-diagonal PDP-HDTV receiver, the “Nagano Model,” was developed using the methods proposed.",
