Visual comfort of coloured background display stimuli under the dark environment

The purpose of this study was to investigate visual comfort of coloured background stimuli on a mobile display in the dark environment. Seventy-eight rendered images were created with backgrounds covering 6 CCT and 13 Duv coordinates. Twenty observers evaluated visual comfort using a 6-category points method. The results showed that visual comfort decreases with Duv reaching -0.0011. The highest background visual comfort levels were 5000K and 6500K, followed by 4000K, 8000K, 10000K and 3000K. A model was developed to evaluate the visual comfort of colour stimulus.
