Abstract

The front-of-screen quality as the visual performance of thin- film transistor liquid crystal displays were investigated using the original algorithm for uniformity analysis. Extraction and evaluation of 'mura,' which was low-contrast and non-uniform brightness region, was successfully demonstrated using commercial-available test system with our algorithm. The algorithm was led out from researching of sensory analysis and human perception. The sensitivity of the technique was demonstrated by a detectable change at even the small level which was perceptible by experienced manufacturing inspectors. The evaluation and judgement for 'mura' using our technique closely matched the results from the experienced inspectors.
