Abstract

The invention belongs to the technical field of quantum dot diffusion plates, and particularly relates to a high-brightness quantum dot diffusion plate structure and a manufacturing process thereof. The high-brightness quantum dot diffusion plate structure comprises a shell assembly, a display assembly and packaging assemblies, wherein the packaging assemblies are fixedly installed on the periphery of the display assembly, the display assembly is installed in the shell assembly, the shell assembly comprises a bottom shell and an upper shell, the inner wall of the right side of the bottom shell is rotationally connected with the inner wall of the right side of the upper shell through hinges, a supporting piece is fixedly installed at the bottom of the shell assembly, the display assembly comprises a light guide plate, a color scattering plate, a first quantum dot film, quantum dots, a second quantum dot film and photonic crystals, and the periphery of the outer wall of the display assembly is fixedly connected with the packaging assemblies. According to the invention, the periphery of the display assembly is uniformly coated with EVOH coating liquid in a dust-free and oxygen-free working chamber, and the EVOH coating liquid is cured through ultraviolet illumination to package all the parts in the display assembly, so contact between the quantum dots and oxygen and moisture is completely eradicated from the source, and the oxygen-blocking and water-blocking effects of the display assembly are improved.

Description

technical field [0001] The invention relates to the technical field of quantum dot diffusion plates, in particular to a high-brightness quantum dot diffusion plate structure and a manufacturing process thereof. Background technique [0002] Quantum dots are nano-scale semiconductors. By applying a certain electric field or light pressure to this nano-semiconductor material, they will emit light of a specific frequency, and the frequency of the emitted light will change with the size of the semiconductor. Therefore, by adjusting the size of this nano-semiconductor, you can control the color of the light it emits. These semiconductor materials can absorb light. When they release this energy, they convert it into light of different colors. Quantum dots produce The specific color of the quantum dot depends mainly on the size and material of the quantum dot, and the reason for this is something called quantum confinement, when the light excites the quantum dot, the larger the qua...
