“…The results showed that with a decrease in contrast and increase in ambient luminance, the self-reported valence decreased, and the annoyance and VF increased. 1,17 However, the ambient illuminance and display luminance involved in these studies are within a specific small range. In addition, most of them are based only on VP, without consideration of the effects of comfort and VF.…”

Self-luminous display devices are essential in various working environments, such as aircraft cockpits and the driver cab of vehicles and trains, where the external light environment varies drastically. Owing to the significant illumination changes, auto-adjusted display luminance based on ambient lighting is necessary for drivers to work efficiently and comfortably. This study proposes a display dimming model based on three dimensions of ergonomic testing, consisting of visual performance (VP), visual comfort (VC), and visual fatigue (VF). Five ambient illuminances, each combined with five display luminance levels, form a total of 25 conditions demonstrated in this experiment. Using a within-subject design, ten observers experienced all the combination conditions. The experiment employs the Anfimov table to test the VP, VC scale to evaluate VC, and VF scale to assess VF. Based on the experimental results, sub-models are constructed to clarify the characteristics of each dimension (VP, VC, and VF). Subsequently, the analytic hierarchy process is employed to construct an evaluation system by calculating the weight of each dimension in the total score. Finally, exponential fitting is utilized to build a widerange display dimming model, which explicitly describes the inherent connection of complex light environment matching. © The Authors.

“…Importantly, their experiments showed that these luminance levels vary with color, polarity, and image content. Another perspective on the relevant topic was also introduced to find an optimum luminance for display under different illuminations in terms of visibility and power consumption [5] . The authors claimed that the luminance levels for indoor use between 200 and 500 cd / m 2 would be satisfactory.…”

This paper introduces a psychophysical experiment to investigate the image quality trade‐off relationship between peak luminance and the chromaticity area of the color gamut of a display device and models to predict equivalent image quality based on the experimental results. Our experimental results confirmed the hypothesis that the peak luminance required to maintain equivalent image quality tends to decrease as the color gamut area expands. At the same time, the relationship between peak luminance and color gamut strongly depends on image content. Based on the experimental results, two models are suggested. These models show good performance in terms of predicting the required luminance levels for given color gamut areas. Notably, the model built using an observer‐chosen region of interest (ROI) in an image slightly outperforms the model generated without this information.
