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.

基于血流动力学响应的显示器亮度对黑暗环境中视觉不适的影响

显示亮度是最重要的因素之一，不仅会影响显示性能，还会极大地影响视觉不适。为了研究显示亮度和图像内容对视觉不适的影响，分别记录了参与者观看不同视觉刺激时的血流动力学反应和主观感觉。本研究采用不同的显示白电平（WLs）和具有不同空间振幅谱的图像作为视觉刺激，并应用特定的黑暗环境。结果表明，在黑暗环境条件下，WL对视觉不适有显着影响，在不同空间幅度谱的图像中表现不同。研究结果还表明，对于视觉不适测量，
