Motional artifacts appearing in high resolution images on plasma displays

摘要

When images having high spatial frequency components move on a PDP screen, perceived information is distorted in various ways such as contrast deteriorates, change of the number of the stripes, blur at the edge and new-born stripes. The picture quality cannot be improved only with an increase in the number of the sub-fields. It can neither be improved by employing the sub-field arrangement which is different from the binary-coded schemes. The error diffusion method deteriorates resolution and does not solve the problem. The artifacts can be reduced by a use of the equalizing-pulse technique together with increased number of sub-fields.
