ABSTRACT:
The present invention relates to to an apparatus for driving a plasma display panel in which an image being full of life is represented through expansion of contrast and the gray level can be expanded, and method for driving the same. According to the present invention, since a gray level of an input data is distributed over the whole gray level region, contrast can be expanded. It is therefore possible to display an image being full of life. Furthermore, if the gray level of the input data is expanded over the whole gray level region, contrast is increased. Moreover, when the gray level region is expanded, an error diffusion unit and/or a dithering unit are/is not used.
