Error Diffusion Method for Improvement of Gray Scale Rendition in PDP

This paper proposes an error diffusion method for improvement of gray scale rendition in plasma display panel(PDP). The conventional error diffusion method in PDP, which includes data separation for display and error part, may have a danger of wrong calculation of error to diffuse. The proposed approach suppressed the halftone artifact by calculating the error using the gray level itself. Thus, the proposed method accurately reproduces the gray level by driving the average error to zero. Experimental results, obtained using two benchmark images, nine wellknown test images, and 104 random HDTV images, illustrated that the proposed method has smaller halftone artifacts than the conventional method does.
