液晶蓝光危害研究

Study of the blue light hazard of liquid crystal

运用光栅分光原理,将液晶屏中的有害蓝光按照危害权重分离出来,通过测量蓝光的光照度表示蓝光的危害大小,为评估液晶屏幕的蓝光危害提供了一种简化方法.通过对大量液晶屏幕在不同影响参数下的蓝光光照度测量,得到液晶蓝光危害的一些规律,提出了减少使用液晶屏幕以及合理使用液晶屏的建议.

Using the principle of grating spectroscopy, the harmful blue light is separated from the lights of liquid crystal display. By measuring the illumination value representing the damage of blue light, we provide a simplified method of evaluating the blue light hazard from the screen. Through the massive measurement of blue light hazard of liquid crystal on different conditions, some conclusions are drawn about the hazard. And some suggestions are raised that less liquid crystal should be used as well as used properly.
