Abstract
In a method of expressing a gray level of a high load image and an apparatus for driving a Plasma Display Panel (PDP) using the method, a load ratio of the input image signal is calculated, and an error diffusion of a lower bit of gray level data corresponding to the input image signal is performed when it has been determined that the calculated load ratio is greater than or equal to a critical load ratio which is a lowest load ratio among the load ratios in which luminance at every gray level does not increase while the gray level increases at a low gray level area. The error-diffused gray level data is then displayed on the PDP.
