Abstract

The invention provides a light conversion film, a preparing method thereof and a liquid crystal display module. The light conversion film comprises a first substrate, a thin film layer, a quantum layer and a second substrate, wherein the first substrate, the thin film layer, the quantum layer and the second substrate are sequentially stacked, and quantum dots are distributed on the quantum layer. The thin film layer is a transparent thin layer with an electric field on the surface. The quantum dots are orderly distributed under the effect of the electric field. By means of the scheme, the light outgoing directivity can be more concentrated, and therefore the light conversion efficiency can be effectively improved.

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 ...
