Abstract
A method for reducing dynamic false contour in a plasma display panel (PDP) comprising the steps of selecting gray scales of different visual concentration series from all of gray scales available to be shown on said PDP to form a visual concentration conversion table, selecting at least one of said visual concentration series as a virtual visual concentration series, and converting original input value of gray scale of each discharge unit into corresponding gray scales of different visual concentration series and virtual visual concentration series, while showing each field of a dynamic image on said PDP, in order to average visual concentration difference between gray scales of two adjacent discharge units on the dynamic field into a smaller one.
