Abstract :
A novel method that evaluates white uniformity grade of electronic displays based on S-CIELAB color system is presented. The spatial filter is defined by using the color contrast sensitivity function, and the mura (non-uniform region) index E is also defined to evaluate the white uniformity grade quantitatively. The experimental results showed strong relations between human sensory evaluation scores and the mura index E values.
