“…Compared to the environment light, the light emitted from displays goes into the retina directly [16], and is the major cause of visual discomfort. It has been found that the display luminance affects visual discomfort obviously [7], [8], [16]- [22]. Excessive display luminance induces glare, causes difficulty in perception of information and results in severe visual discomfort [17], [20].…”

Display luminance is one of the most important factors that influence not only display performance but also visual discomfort greatly. To investigate the influence of display luminance and image content on visual discomfort, the haemodynamic response and subjective perception were recorded respectively when participants watched different visual stimuli. Different white levels (WLs) of display and images with different spatial amplitude spectra were adopted as the visual stimuli, and specific dark environment was applied in the study. The results showed that under dark ambient condition, the WL had significant influences on visual discomfort, which varied in images with different spatial amplitude spectra. The findings also indicated that, for visual discomfort measurement, the sensitivity of haemodynamic response was better than subjective evaluation.

“…For example, Na and Suk asked the observers to read an article on a 4.8‐inch smartphone display (maximal luminance of 140 cd/m 2 ) in a dark room with an ambient illuminance below 1 lx and found that the display luminance of 40 cd/m 2 was the most preferred. Wang and his colleagues asked the observers to view 3D pictures on a stereoscopic display (maximal luminance of 47.3 cd/m 2 ) under the ambient illuminance of 55 and 300 lx and found the highest display luminance was rated as the most comfortable.…”

Many tablets are designed to change display brightness or color with surround for enhancing visual comfort. Although both color and brightness of a surround may vary a lot, few studies investigated how text‐background lightness combination of a tablet display and surround jointly affect visual comfort, and how display white point affects visual comfort. In this study, 20 observers evaluated visual comfort of 20 text‐background lightness combinations of a 9.7‐inch tablet display through paired comparisons under five surrounds—a dark surround and four ambient lighting conditions comprising two levels of correlated color temperature (CCT)—3500 and 6500 K—and illuminance—300 and 3000 lx. The combination of a black text and a light‐gray background (i.e., L*background = 75.33; L*text = 1.6) was evaluated the most comfortable when there was ambient light regardless of CCT and illuminance. It was also evaluated the third most comfortable under the dark surround. The observers also evaluated the visual comfort of a dark text on five different white backgrounds under 3500 and 6500 K at 1000 lx. The color of the background that was judged as the most comfortable neither had the whitest appearance nor matched the color of the ambient light. The simultaneous adjustment of the display white point and the text‐background lightness combination merits further investigations.

“…The authors suggested that viewers felt the most comfortable and demonstrated the best visual performance in the high levels of both display luminance and ambient illumination. 9 Our earlier study explored visual comfort for 2D and 3D modes of the shutter glass and pattern retarder types of stereoscopic televisions (TVs) in terms of AI, monitor luminance, background luminance, and image content (IC). The evaluation results demonstrated that AI affects visual comfort in both 2D and 3D modes of shutter glass and pattern retarder types of TVs.…”

Visual comfort in autostereoscopic display

Autostereoscopic displays are likely to become widely used products in the future. However, certain physiological factors, especially visual comfort, limit their development. In this study, four observational parameters – ambient illuminance, image content, scaling ratio, and horizontal distance between major and minor objects – were evaluated to determine the degree of visual comfort offered by 3D computer‐generated images on an autostereoscopic display. Visual comfort score with the range of 0–1 is designed to represent the degree of visual comfort for the 3D images with different manipulations of ambient illuminance, image content, scaling ratio, and horizontal distance between major and minor objects in this study. Subjects were asked to indicate images that produced discomfort. The proportion of images for each condition where participants indicated that viewing the image was comfortable was computed. Images receiving a proportion of 0.5 or greater were classified as acceptable. The disparity ranges over which acceptable images were attained for each participant and for each condition were analyzed with analysis of variance. The analytical results indicate that ambient illuminance and image content have a significant effect on the acceptable disparity range, while scaling ratio and horizontal distance between major and minor objects did not.
