摘　　要：当前光生物安全研究多针对光谱分布恒定的人工照明,且较少考虑人眼透射率随年龄变化的影响。未来20年AMOLED可能将逐步成为智能手机的主流显示屏。为了探索AMOLED的蓝光危害与节律效应与使用者年龄的关系,为AMOLED个性化设计及使用提供理论参考,我们根据CIE 203-2012A给出的人眼透射率随年龄变化的函数表达式,得到了11个不同年龄(1—100岁,每间隔10岁)人眼透射率。采集了6个不同色温(2 300、 2 700、 3 400、 4 100、 5 000和6 500 K)AMOLED 380~780 nm可见光波段的原始光谱分布数据,对不同色温下AMOLED的原始光谱分布数据进行归一化处理,由不同色温下AMOLED的归一化光谱分布数据乘以不同年龄人眼透射率,得到不同年龄下不同色温AMOLED在人眼视网膜上的有效光谱分布。利用人眼视网膜有效光谱分布,代替蓝光危害因子与节律因子计算公式中的原始光谱分布,计算了AMOLED在不同年龄人眼视网膜上有效光谱分布的蓝光危害因子与节律因子。通过高质量函数拟合分析,研究了AMOLED的蓝光危害与节律效应随年龄变化。研究分析结果表明:AMOLED的蓝光危害与节律效应均随使用者年龄的增大而降低;对于色温为6 500 K的AMOLED,使用者年龄由1岁增加至100岁,视网膜有效光谱的蓝光危害因子与节律因子分别降低为原来的0.290 7和0.403 8倍;当年龄大于40岁时,各色温的蓝光危害因子与节律因子随年龄增加而降低的速度均明显加快;6个不同色温下,40—100岁的蓝光危害因子与节律因子随年龄增加而降低的平均速度,分别是1—40岁的2.748 2和2.993 3倍;当年龄由1岁增加至100岁,6个色温的平均蓝光危害因子与平均节律因子分别下降为原来的0.305 6和0.452 0倍。由以上结果知:AMOLED对年轻人的蓝光危害与节律效应较大,特别是年龄小于40岁的年轻使用者,应减少使用时间,注意蓝光危害与节律效应;蓝光危害受Current research on photobiosafety focuses on artificial lighting with a constant spectral distribution.The influence of human transmittance with age is less considered.In the next 20 years,AMOLED will gradually become the mainstream display of smart-phones.This paper provides a theoretical reference for the personalized design and use of AMOLED from the perspective of blue light harm and rhythm effect.According to the function expression of the change of human eye transmittance with age given by the International Commission on Illumination(CIE)in 2012,the transmittance of the human eye was obtained for 11 different ages(1~100 years,with intervals of 10 years).We collected the original spectral distribution data of AMOLED at six different color temperatures(2300,2700,3400,4100,5000,6500 K).We normalized the original spectral distribution data of AMOLED at different color temperatures.Then,we multiplied the normalized spectral distribution data of AMOLED at different color temperatures by the transmittance of human eyes at different ages and finally obtained the effective spectral distribution of AMOLED at different color temperatures on the retina of human eyes at different ages.We used the effective spectral distribution of the human retina to replace the original spectral distribution of the blue light hazard factor and rhythm factor in the calculation formula,and calculated the effective spectral distribution of the blue light hazard factor and rhythm factor of AMOLED in the human retina at different ages.Through the high-quality function fitting analysis,the blue light harm and rhythm effect of AMOLED with age change were studied.The research and analysis results show that:The blue light harm and rhythm effect of AMOLED decrease with the increase in the user's age.For AMOLED with a color temperature of 6500 K,the user's age increases from 1 year to 100 years,and the blue light hazard factor and rhythm factor of the retinal effective spectrum decrease to 0.2907 and 0.4038 times respectively.When the age is mor
