Determination of magnitudes of motion-dependent equalizing pulses for reducing the gray scale disturbances on PDPs

Abstract

Determination of the magnitudes of motion-dependent equalizing pulses for reducing the gray scale disturbances on plasma display panels (PDPs) has been examined. First, amounts of light intensity perceived by the retina are calculated. Then the pixels to which to add the equalizing pulses are determined by checking whether the disturbance is dark or bright. Also appropriate sub-fields of each pixel are chosen for emission compensation. Finally, a feedback loop is provided for a fine adjustment of luminance. The technique is applicable to any sub-field configuration.
