Super-Gaussian light spread function was designed for high dynamic range liquid crystal displays. A dual-liquid-crystal-panel system was constructed to simulate an HDR display, and to evaluate the implementation of the proposed super-Gaussian and a general Gaussian distributions. According to the results, luminance uniformity and processing time of super-Gaussian LSF are superior to those of Gaussian LSF by factors of 1.55 and 178, respectively. Contrast ratio is improved by a factor about 2 to 4.15 as well. In addition, the undesired artifact, grid lines, can be suppressed to be invisible.
