Problems solved by technology

However, the mesoporous structure of P-type semiconductor materials has little research on the electro-optic properties of liquid crystals.
Moreover, at present, the research of nanomaterials on the electro-optic properties of liquid crystals is mainly focused on the nematic phase, while systematic research has less influence on the electro-optic properties of the nematic phase and cholesteric phase.

Abstract

The invention discloses a method for enhancing the electro-optical performance of liquid crystals by Cu2O nano-particles and belongs to the technical field of liquid crystal display. The method is characterized in that Cu2O nano mesoporous spheres and Cu2O nanospheres of the same size are doped with cholesteric liquid crystals N*-LCs at the mass fraction of 0.10-0.50% to form a nano material and liquid crystal compound, Cu2O MPS and Cu2O NS of the same size are doped with nematic liquid crystals 5CB at the mass fraction of 0.001-0.200% to form a nano material and liquid crystal compound, and prepared liquid crystal baths are adopted for electro-optical performance test. As a small quantity of Cu2O nano material is doped with the liquid crystals, the driving voltage of both the cholesteric liquid crystals and the nematic liquid crystals can be greatly reduced, and the voltage decreasing amplitude of the liquid crystals doped with the mesoporous spheres is larger than that of the liquid crystals doped with the nanospheres.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to the electro-optic properties of liquid crystals. Specifically, it refers to a Cu 2 A method for O nanoparticles to enhance the electro-optic properties of liquid crystals. By doping Cu into liquid crystals (nematic and cholesteric) 2 O nanoparticles greatly enhance the electro-optical performance of liquid crystal, reduce the driving voltage and response time of liquid crystal display, etc., and solve the technical problem of high driving voltage of liquid crystal display. Background technique [0002] Nematic liquid crystals (LCs) have occupied a very important position in the field of liquid crystal displays due to their high contrast ratio and low driving voltage. Cholesteric liquid crystals (N*-LCs) have been widely used in liquid crystal display industry because of their unique properties. However, the rapid development of the LCD industry has put forward ...
