Problems solved by technology

[0002] Quantum dots are used in display panels, which have the advantages of long life and wide color gamut, but also have the problem of low light conversion efficiency.
In order to improve the light conversion efficiency of quantum dots, under normal circumstances, it is necessary to increase the thickness of the quantum dot structure layer (thickness increases, the quantum dot quantity in the quantum dot structure layer increases, the number of light rays irradiated on the quantum dots increases, and the conversion rate of light improvement), however, due to the limitation of the printing nozzle on the manufacturing process, it is difficult to make the quantum dot structure layer thick
