An area of uneven brightness is a typical defect which influences the screen quality of a LCD display. At present in LCD manufacturing lines, inspection of such uneven areas depends on sensitive visual judgements by skillful inspectors. To automate the inspection process, an inspection system is required which can determine the degree of defect of uneven areas using a visual recognition system with a discriminatory capability similar to human sight. An evaluation of the relation between the characteristics of uneven areas and their visual conspicuity degree is also needed. This paper describes experiments to evaluate the characteristics of uneven areas that influence human visual perceptibility. The experimental results show that contrast, location, diameter, aspect ratio, width and length influenced visual perceptibility.
