“…It is assumed the factors critically affect visual perception and in turn inspectors and general users presumably determine the display quality differently with varying combinations of factors. These parameters were heuristically derived from past visual performance evaluation experiences, ergonomics (Jorna, 1991;Padmos & Milders, 1992;Zhu & Wu, 1990), psychophysics (Gescheider, 1985), information displays (Barten, 1990(Barten, , 1991Brill, 1990;Cappels, 1993;MacAdam, 1943;Purnomo, Hasegawa, Asano, Shigeta, & Shimizu, 1997;Sherr, 1993;Siminoff, 1997;Snyder, 1984), and international standard (ISO 9241-3, 1992) in the area of measuring uniformity of a VDU monitor. As well, a pilot test within the company was taken to inspect the statistical significance of these factors using experimental data.…”

White uniformity indicates the degree of uniform distribution of white color across the display screen and is one of the important inspection factors determining the image quality of a visual display unit (VDU). Experiments in which participants were confronted with 6 evaluation points embedded in 3 measurement groups on a VDU screen were conducted to gather the psychophysical data that include the levels of white uniformity obtained from participants and a colorimetric system (CA-100). In an accuracy test, 37.12% of the participants showed the same conclusion led by the original CIE1976 criteria, and 62.88% of the participants showed the same conclusion led by the modified equation. In magnitude estimation evaluating the display's white uniformity, the magnitude score of the modified equation (0.36) was significantly larger than that of the original equation (0.32). It was concluded that the modified equation is more sensitive to the change of white uniformity.
