Abstract:
A driving system for a plasma display panel having a plurality of row electrodes and a plurality of data electrodes which intersect with the row electrodes, comprising:a table storing a plurality of correcting pixel data, each of the correcting pixel data being divided into a plurality of sub-frames;discriminating means for discriminating whether an input video signal is a moving picture signal or a still picture signal, and for producing a first discrimination signal;an A/D converter for sampling the video signal for producing a pixel data having n-bit;pixel data processing means for converting the pixel data into a false contour correcting pixel data having a (n+m)-bit based on a correcting pixel data derived from the table;changeover selecting means for selecting either of the false contour correcting pixel data or the pixel data from the A/D converter;control means responsive to the first discrimination signal for controlling the changeover selecting means so as to select the false contour correcting pixel data when the input video signal is a moving picture signal, and to select the pixel data from the A/D converter when a still picture signal;a memory for storing a data divided into a plurality of sub-frames and selected by the changeover electing means; anddriving means for driving the plasma display panel by a pixel data derived from the memory.
