Plasma display panel (PDP) has become popular as high-end television monitors. In PDPs, gray levels are expressed by the pulse-number modulation technique to generate gradation display. Although this method can display still image faithfully, it can yield annoying distortions when displaying moving images. In order to reduce the dynamic false contour and develop moving picture quality, we propose a rough set based effective subfield optimization technique. Simulation results show that the dynamic false contour can be effectively reduced by rough set based subfield optimization algorithm.
