Investigation of the Optimum Display Luminance of an LCD Screen under Different Ambient Illuminances in the Evening

Ambient illuminance and screen luminance have a significant influence on the visual fatigue performance associated with use of computers. The current study was conducted to investigate optimal under different ambient illuminances fit curve optimum LCD screens evening illumination. Thirty-three participants were assigned rate brightness, comfort luminance, satisfaction six levels (3.87, 21.47, 42.74, 64.12, 84.77 106.7 cd/m2) combined five (0, 25, 50, 75 100 lx) in evening. results showed that increased increasing illuminance. Moreover, should be range 13.08–62.16 lx 20.63–75.15 cd/m2, respectively, obtain subjective feelings during
