Permissible Luminance of Disturbing Reflections of Light Source on CRT Displays

Abstract

The purpose of this paper is to consider the effect of CRT display image characteristics upon permissible luminance of reflected images of light source. In experiment 1 subjects were asked to adjust the luminance of disturbing light source on permitted luminance. The results showed that permissible luminance of disturbing reflections on the positive polarity display (dark character) was about three times higher than on the negative polarity display (light character). In experiment 2 subjects were asked to count the number of specific character in the displayed textual material containg disturbing reflection. The results showed that no significant differences in the effect of disturbing reflections on visual performance can be attributed to display polarity
