Effects of reflection properties of liquid-crystal displays (LCDs) on the reflected glare disturbances were investigated by subjective rating. We studied seven TFT-color LCDs and three CRT displays having different anti-reflection treatments. The specular reflection coefficients of these displays were measured for different source sizes. The disturbing reflections on these displays were subjectively rated to elucidate the relationship between the specular reflection coefficient and the reflected glare disturbance. The results indicated that the interrelation was most obvious (r2>0.9) for a 1-degree source between the specular reflection coefficient and the subjective rating of the glare disturbances from the overhead illuminations. Similarly the subjective ratings of reflected glare from a simulated window were estimated from the specular reflection coefficient for a 10-degree source size. These results have been incorporated into a model for predicting reflected glare disturbances.
