Abstract

The invention provides strain liquid crystal dimming display glassware which is light and portable and can be in a scattering mist state with a pattern display effect under an ordinary condition. After shearing stress is exerted on the glassware, the glassware can be in mist semi-transparent state, a pattern is blanked, and the glassware can be applied to various display pattern product manufacturing effectively, is not easy to crack and has wide application prospects and markets. The invention further provides a manufacturing method of the strain liquid crystal dimming display glassware. A polymer dispersed liquid crystal layer is clamped between two pieces of organic glass and is formed by mixing a prepolymer, nematic phase liquid crystal and a gasket material. The mass ratio of the prepolymer to the nematic phase liquid crystal is 13:7-15:7. The major components of the prepolymer are, by mass, 30% of alkoxy phenylacrylic acid ester, 60% of trimethylolpropane acrylic ester, 4% of chemigum, 4% of 2-mercaptoethanol and 2% of 1173 photoinitiator.

Description

technical field [0001] The invention relates to the technical field of strained liquid crystal displays, in particular to a strained liquid crystal dimming display glass product and a preparation method thereof. Background technique [0002] Polymer dispersed liquid crystal (PDLC) and polymer network liquid crystal (PNLC) are composite systems of polymers and liquid crystals. In the study of polymer dispersed liquid crystals and polymer network liquid crystals, it was found that the application of stress on the polymerization of polymers and the alignment of liquid crystal molecules It has influence, that is, the effect of stress-induced liquid crystal orientation. This research field is called strained liquid crystal (SLC); the product of polymer dispersed liquid crystal electronically controlled dimming film has a foggy appearance of frosted glass, and it becomes transparent when an electric field is applied. The strained liquid crystal technology has been adopted The posi...
