Abstract

This study investigated the effect of ambient illuminance (50, 500, 1 500, 3000, 6000, and 9000 l×) on participants' visual performance using four electronic displays (conventional LCD under transmissive mode, conventional LCD under reflective mode, Ch-LC display, and E-ink display). Analysis results indicate that participants' visual performance shows significant difference under various ambient illuminance and electronic displays. The interaction between ambient illuminance and electronic display also has significant effect on participants'visual performance. When participants use the conventional LCD under transmissive mode, ambient luminance has no significant effect on participants' visual performance. However, participants' visual performance is significantly different under various ambient illuminances using the conventional LCD under reflective mode, Ch-LC display, and E-ink display. The conventional LCD under transmissive mode is the only choice at a lower illuminance of 50 l×. Higher illuminance (500 l×) for E-ink displays may result in as good a performance as the conventional LCD under transmissive mode; nevertheless, much higher illuminance (1 500 l×) for the conventional LCD under reflectance mode and Ch-LC display may achieve better performance.
