1. A method for displaying an image on a liquid crystal display comprising:

  • (a) illuminating a first pixel at a first non-zero illumination level during an initial frame;

    (b) illuminating said first pixel at a second non-zero illumination level during a subsequent frame, wherein said subsequent frame is temporally later than said initial frame;

    (c) wherein said first pixel is selectively decreased in illumination to an intermediate illumination level, based upon an estimation of temporal blur of said first pixel, after illuminating said first pixel during said initial frame and before illuminating said first pixel during said subsequent frame.1 1 Novelty resides in the use of temporal blur.
