Abstract
AbstractSuper‐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.
