A driving apparatus for plasma display panel and a gray level expressing method thereof that reduces pseudo-contour. A row average gray level value is calculated through simulation after displaying a test image with different gray levels, and the respective gray levels are classified into a plurality of gray level groups according to the probability of pseudo-contour. The gray level conversion is performed differently according to the plural gray level groups. The gray level values of two frames input consecutively and the illuminating patterns of the subfields are compared to detect the pseudo-contour, and the detecting result is applied to the gray level groups to perform the different gray level conversions. |
