A gray scale expression method in a plasma display panel (PDP) and a driving apparatus for the PDP improves color coordinate adjustment. When the brightness coefficient of an input image signal is varied step by step in accordance with an external adjustment signal, a dithering algorithm is applied to the image signal to vary the gray scale of the image signal by 0.25 for every variation of the brightness coefficient. The dithering algorithm is applied to the pixels or frames of the input image signal such that the pixels or frames exhibit opposite characteristics in a time direction. |
