Abstract
The inventions provides a light conversion film and a manufacturing method and a liquid-crystal display module thereof, which comprise laminated first substrate and second substrate, a first water oxygen barrier layer and a second water oxygen layer set between the laminated first substrate and second substrate, and a nano layer, wherein the nano layer is located between the first water oxygen barrier layer and the second water oxygen barrier layer; photoluminescence molecules are arranged to form the nano layer; the photoluminescence molecules are polar molecule; and a skeleton direction of the photoluminescence molecules is vertical to the nano layer. With the solution provided herein, light emitted from the nano layer can be effectively sent to a display panel side; and the problem of light emission loss caused by luminescence isotropy of a quantum dot in the existing technology is avoided, thus improving the light effect.
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 display field. Specifically, when the light conversion film distributed with quantum dots is excited by the light source, the quantum dots can emit light of different chromaticity and transmit to the display panel located on one side of the light conversion film. [0003] Quantum dots emit isotropic light after being excited by a light source. However, in practical appli...
