摘要
针对以发光二极管为背光源的平板显示对人体生理节律等非视觉的影响,采用节律因子评价模型设计了实验系统.通过全空间平均辐射法,采用国际电工委员会标准中平均图像电平的节目画面,测量显示不同图像时以发光二极管为背光源的平板显示器光辐射的节律因子.结果发现: 以发光二极管为背光源的平板显示器在显示白场和大部分彩色图像时的节律因子为5.0以上,其非视觉效应比普通照明要强得多,且与显示的图像内容密切相关;该平板显示器的光学辐射对人体生理节律等非视觉具有不可忽视的影响.
Abstract
Aiming at the non-visual effects of optical radiation of the flat panel display with light emitting diode backlight on human circadian rhythms, an experimental system is designed using a model of the evaluation of the circadian factor. By the method of average radiation in total space, the circadian factors of different pictures displayed on flat panel display with light emitting diode backlight are measured, and the pictures are all from the program of Average Picture Level in the International Electrotechnical Commission standard. It is found that the circadian factors of flat panel display with white and majority of colorful backgrounds are above 5.0, which are much stronger than ordinary lighting source, and are closely related to the content is displayed. The result suggests that the non-visual effect of the optical radiation of flat panel display on human circadian rhythms should be considered.
