不同手机屏幕对青少年生理节律和蓝光危害的影响
|
摘要
针对市场上三款常见的不同材质的手机屏幕(LED背光LCD、OLED、SUPER AMOLED),在黑暗中、屏幕距离瞳孔15 cm处4种不同色温的条件下,研究不同手机对青少年生理节律和蓝光危害的影响。在充分考虑年龄、人眼受光面积、透射率的情况下,改进传统计算蓝光危害因子的公式,并计算节律因子和蓝光危害因子。结果表明,不管何种手机,节律因子和蓝光危害因子都随色温升高而增大,并且均呈现出良好的线性关系。在7 425～9 201 K色温下,节律因子由大到小依次为:OLED> SUPER AMOLED> LED背光LCD;而蓝光危害因子由大到小依次为:LED背光LCD> SUPER AMOLED> OLED,由此可以根据不同需求,选择相对更健康合适的手机。
This paper researches on the influence of the three normal different material cellphone screens (LED backlight LCD,OLED,SUPER AMOLED) on adolescents circadian factor and blue light hazard factor in dark on condition that the distance of cellphones screen from pupil is 15 cm and four different color temperature. With the age,area of eye light exposure and transmittance being considerd,the calculating formula of traditional blue light hazard factor is upgraded. Circadian factor and blue light hazard factor are also calculated. It is shown that circadian factor and blue light hazard factor increase with the increase of color temperature and strong linear relation is also exist.when color temperature is between 7 425 K and 9 201 K,circadian factor ranked from high to low follows: OLED,SUPER AMOLED,LED backlight LCD. Blue light hazard factor ranked from high to low follows: LED backlight LCD,SUPER AMOLED,OLED. As a result,a relatively healthier cellphone can be chosen appropriately,according to different requirement.
