近年来, 蓝光对人眼的危害逐渐被人们所认识和关注。蓝光危害风险不仅存在于照明光源中, 还存在于显示产品中。减少蓝光的含量是降低蓝光危害的直接方法。而蓝光是显示产品光谱中必不可少的组成波段, 同时也是满足显示产品色温和色域需求, 完美展现丰富多彩的真实世界的必需颜色。因此如何在不降低正常显示标准下, 发展抗蓝光危害的技术是显示技术的一个重要研究方向。目前, 国内外众多研究者围绕蓝光生物安全性及防蓝光显示技术进行了较深入的研究。本文首先阐述了蓝光危害的作用机制、危害分类和评估方法、标准, 分析了显示产品中影响蓝光危害程度的多种影响因素。介绍了目前防蓝光显示技术新进展, 并对防蓝光显示技术进展进行了总结和展望。

In recent years, the harm of blue light to human eyes has gradually been recognized and concerned by people. Blue light hazard exists not only in illumination sources, but also in display products. Reducing the blue light content is a direct way to reduce the hazard of blue light. However, blue light is an indispensable component band in the spectrum of display products. It is a necessary color to meet the needs of color temperature and gamut of display products, as well as to display the real color of the world. Therefore, the anti-blue light hazard technology of display products without lowering the normal display standard has been an important research direction in the display field. At present, many researchers at home and abroad have conducted many research on blue light hazard and anti-blue light display technology. In this paper, the mechanism, classification and evaluation methods and standards of blue light hazard were explained. And then the influencing factors of blue light hazard in the display products were analyzed. Moreover, the new progress of anti-blue light display technology was introduced and summarized.
