Abstract

We fabricated an experimental measuring system for thin-film transistor liquid crystal display (TFT-LCD) screens based on Ergonomic requirements by ISO 13406-2. It consisted of a controller, an automated rotating stage, a charge-coupled-device (CCD) camera, and a pair of light sources. The whole display screen could be evaluated from various viewing angles under the illumination of conditions it is usually used under. The possibility of appropriate measurements of non-uniformity luminance or "mura" based on the sensory analysis was also confirmed.
