Popis:	The luminance non-uniformity of LED backlight was evaluated by using artificial indistinct Mura images with five different forms, two sizes, and three contrasts. The results show that Mura size and contrast significantly affect the subjective evaluation. Analysis of the relationship between the subjectively evaluated luminance non-uniformity and the luminance distribution characteristics of Mura images showed that the Mura edge areas, low luminance areas, and maximum luminance difference between a Mura and a uniform image are important for predicting a subjective evaluation for luminance non-uniformity of indistinct Mura.
