Abstract

The present disclosure provides a light conversion film and a preparation method thereof, and a liquid crystal display device. The light conversion film comprises a first substrate, a thin film layer, a quantum dot layer in which quantum dots are distributed, and a second substrate, which are all successively stacked, wherein said thin film layer is a transparent sheet having an electric field on a surface thereof, and said quantum dots are orderly arrayed due to said electric field.

Description

technical field [0001] The invention relates to the display field, in particular to a light conversion film, a preparation method thereof, and a liquid crystal display module. Background technique [0002] Quantum dots, also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between 1 and 10nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure with molecular characteristics, and can emit fluorescence after being excited, so quantum dots It is widely used in the field of display. The structural layer with quantum dots is the quantum layer. Under the excitation of the light source, the quantum dots distributed in the quantum layer can emit light of different chromaticity. [0003] At present, the distribution of quantum dots in the quantum layer is chaotic and irregular, and the light emitted by the light source irradiates the ...
