Abstract
A method for implementing error diffusion on a plasma display panel (PDP) comprises the steps of performing an anti compensation process on a received video signal of the PDP; diffusing an error generated by a first one of a plurality of pixels to a plurality of adjacent pixels; absorbing errors generated by the plurality of adjacent pixels by the first pixel; and multiplying each of a plurality of numeric weightings and the error of each of the adjacent pixels to obtain an error function of the first pixel. This is effected in a cost effective while simple addition circuit for solving the problem of low level contouring in PDP due to insufficient gray scale of video signal in low gray scale.
