Embodiment Construction

[0053] The invention provides a fluorescent composite thin film with a multilayer structure containing quantum dots, the outermost layer of which is a protective film layer, and the middle layer is a quantum dot layer. The upper and lower surfaces and side surfaces of the quantum dot layer are covered by a protective film layer.

[0054] Such as figure 1 As shown, the quantum dot layer 11 includes green quantum dots 111 , red quantum dots 112 , light diffusing particles 113 , and a film-forming material 114 .

[0055] The preparation method of quantum dot layer is:

[0056] A glue containing quantum dot layer material is coated on the surface of the substrate, and the quantum dot layer is formed after the glue is cured. Examples 1-3 are specific methods for preparing quantum dot layers, see Table 1.

Abstract

The invention provides a long-service-life quantum dot fluorescent composite thin film. The outermost layer of the quantum dot fluorescent composite thin film is a protection film layer and the middle layer of the quantum dot fluorescent composite thin film is a quantum dot layer. The protection film layer and the quantum dot layer can be stuck together. The invention further provides a preparation method of the quantum dot fluorescent composite thin film. The preparation method comprises the following steps: coating glue containing a quantum dot layer material on the surface of a base material; after the glue is cured, forming the quantum dot layer; and covering protection films on the upper and lower surfaces, and the side face of the quantum dot layer. According to the prepared quantum dot fluorescent composite thin film, the stability and the durability of a quantum dot are improved.

Description

technical field [0001] The invention relates to the technical field of quantum dots, in particular to a long-life quantum dot fluorescent composite film capable of improving the stability and durability of quantum dots and a preparation method thereof. Background technique [0002] Quantum dot technology has been applied in the field of display equipment, which can improve the display effect, increase color vividness, color gamut and color rendering index, etc., and increase the color gamut of the display from 70% NTSC to 100% NTSC. The display performance of a display device using quantum dot technology is comparable to that of a display device using OLED technology. [0003] The LED backlight module used in display equipment, the method of producing white light is as follows: ①Through the light emitted by the blue LED, the yellow phosphor is excited to emit yellow light, and the blue light and yellow light are mixed to form white light; ②Through red light, green light and ...
