INVESTIGATION OF GLARE METRICS FOR REFLECTED GLARE ON DISPLAYS (OP15, 84-92)

This work investigates three kinds of surface treatments of displays under ambient lighting conditions. For all treatments of the experiment, the luminous distributions of displays are measured by an Imaging Luminance Measuring Device (ILMD). To evaluate the reflected glare on displays, the joint effects of display polarity and illumination condition were designed in the experiments. Total of 12 reflected glare conditions were measured, three kinds of displays, two types of display polarity contents and two ambient illumination levels. This paper reviewed the popular glare metrics and conducted an experiment to present the applicability of those metrics for predicting glare on electronic displays in indoor environments.
