This paper takes the office LED display screen as the object, and studies the impact of screen brightness on visual performance under different environmental illuminations when people were processing text tasks. Based on three dimensions of behavioral performance, subjective evaluation and physiological indicators, the optimal screen brightness value under different environmental illuminations and optimal brightness contrast range were obtained. Experimental data show that the interaction of screen brightness, ambient illumination and screen brightness has a significant impact on visual performance, while ambient illumination has no significant impact on visual performance. Brightness and contrast have significant effect on visual performance. When the ambient illumination were 50 lx, 300 lx and 500 lx, the optimal value of the screen brightness of the display were about 128 cd/m(2), 178 cd/m(2) and 214 cd/m(2) respectively. The optimal brightness contrast range was 26-30. |
