Abstract

The invention relates to an optical thin film, in particular to a quantum dot thin film. The invention aims to solve the problems that at present, high-energy blue light in quantum dot display severely hurts eyes and the luminous efficiency of a quantum dot thin film is general. The invention provides a high-efficiency quantum dot thin film capable of reflecting blue light and a preparation methodand application of the high-efficiency quantum dot thin film. The quantum dot thin film and a blue-light-resistant film (reflective) are integrated. The high-efficiency quantum dot thin film comprises a quantum dot glue layer, water-oxygen blocking layers and a functional blue-light-resistant layer or film, wherein the water-oxygen blocking layers coat the upper surface and the lower surface of the quantum dot glue layer; and the functional blue-light-resistant layer or film is attached to the upper water-oxygen blocking layer. The functional blue-light-resistant layer or film can reflect blue light, the reflected blue light secondarily stimulates quantum dots, the utilization rate of the blue light is increased, and the luminous efficiency of the quantum dot thin film is qualitatively improved. By the high-efficiency quantum dot thin film, the use amount of the quantum dots can be reduced, an effect of saving cost is achieved well, furthermore, part of blue light can be filtered out,and effects of relieving visual fatigue and protecting eyes are achieved.

Description

technical field [0001] The invention relates to the field of optical thin films, and more specifically relates to a high-efficiency quantum dot thin film capable of reflecting blue light and its preparation method and application. Background technique [0002] Quantum dot TV is a TV that uses quantum dot technology as a backlight source. Like traditional LCD display technology, quantum dot display is also a non-luminous display device that requires a backlight module to provide light. The difference between the two is that traditional LCDs use white light as a light source, while quantum dot liquid crystal displays require blue light to excite the red and green quantum dots in the quantum dot film to obtain a white light source. The light source excited by quantum dots is the purest backlight, revolutionary Realize the full color gamut display, and restore the image color most realistically. [0003] However, while quantum dot TV achieves high color gamut display, it also b...
