In a display driving method, noise is added (NG, AD) to a video signal before the video signal is subjected to a dithering operation (DC). The invention is preferably applied to render non-moving dither patterns invisible in a plasma display panel driving method in which the display signal is subjected to a (Floyd-Steinberg) dithering.
