The present invention relates to the field of optical technology, and proposes a brand-new optical thin film structure, especially an optical thin film structure that can be applied to fields such as LEDs and liquid crystal display screens. It can effectively block and filter the blue-violet band light between 350nm and 500nm, especially it can well block the light blue part below 460nm. The base layer, the blue light blocking layer and the blue light dispersion absorbing layer. At the same time, a UV hardening layer and a scratch-proof layer can be formed on the blue light dispersion absorbing layer during use, and a release protective layer can be formed behind the base layer. The blue light blocking film proposed by the present invention can achieve a blue light blocking efficiency of more than 90%, can well filter the blue-purple harmful band light in LED lighting sources, and can be widely used in any field where LED lighting sources are applicable, and has a broad market prospect . |
