We proposed a numerical model to theoretically simulate visual luminance uniformity and OD (optical distance) value for a mini‐LED array combined with a single layer diffuser. The luminance uniformity curve with increasing light mixing distance obeys the same trend with experimental measurements, which illustrates the accuracy of this theoretical model.
