以LCD手机为研究载体,采取主观打分与客观测量相结合的评价方法,通过主成分分析法对参数降维,分别探究了不同等级的白场亮度和饱和度在暗环境下对视觉舒适度和视疲劳的影响。结果表明,暗环境下LCD手机最佳白场亮度在50 cd/m

左右,此时带来的视觉舒适度综合最优;当饱和度调整系数低于0.7时,会引起视觉上与生理上的不舒适。同时也发现,白场亮度实验给被试带来了一定程度的视觉疲劳和身体疲劳感,而饱和度实验仅产生了视觉疲劳。
The influence of white level and color saturation of LCD smartphone on visual comfort and visual fatigue is researched in this paper. The measurement is performed by the combination of subjective evaluation and objective evaluation, and the principal component analysis is adopted to reduce the dimension of parameters. The results show that the optimal white level of LCD smartphone in the dark environment is about 50 cd/m

with generally higher visual comfort. As to color saturation, the statistically significant discomfort is induced when saturation adjusting coefficient is below 0.7, which brings a degree of visual and physiological discomfort. In addition, LCD cellphone causes the feeling of tiredness both from eye and body after white level experiment while only visual fatigue is found after saturation experiment.
