Abstract

The invention provides a quantum dot composite brightening film and a preparation method thereof, which relate to the field of optical films. The quantum dot composite brightening film comprises a quantum dot film layer formed by a back coating layer, a substrate layer, a first barrier layer, a quantum dot layer and a second barrier layer which are sequentially attached, a composite brightening film layer formed by a diffusion layer, a core layer and a prism layer which are sequentially attached, and an OCA optical adhesive layer connecting the second barrier layer and the diffusion layer. Thequantum dot composite brightening film provided by the invention is provided with the above-mentioned multilayer film structure, and by reducing one substrate layer, the total thickness of the quantum dot composite brightening film is reduced, thereby facilitating the light weight of the quantum dot composite brightening film applied to a backlight module, meanwhile avoiding multiple coating operations on the quantum dot layer, reducing poor processing and effectively improving the performance of the quantum dot composite brightening film.

Description

technical field

[0001] The invention relates to the field of optical films, in particular to a quantum dot composite brightness enhancement film and a preparation method thereof. Background technique

[0002] Quantum dots (Quantum Dots, QDs) are a kind of semiconductor nanocrystals, whose energy band structure can be changed by adjusting the size of quantum dots, so they can emit light of different wavelengths after being excited by a light source. The quantum dot film takes advantage of this characteristic. Under the illumination of the blue backlight, the red and green quantum dots in the quantum dot film are excited to emit red and green light, which are mixed with the unconverted blue light to form white light. Compared with the traditional LCD display, the LCD display using the quantum dot film only replaces the blue light backlight, and the other structures are basically unchanged, and the color gamut can be increased from 70% NTSC1931 to more than 110%.
