Electrically-controlled liquid crystal light modulation glass and film

Abstract

The invention uses the liquid crystal near crystalline state as main material, to be filled between two mediums via special technique, as two layers of glasses, one glass layer and one plastic film layer, or two plastic film layers. When the electrode on the glass or the film is powered, the interlayer liquid crystal distribution is changed, to supply electric control light adjustment function to the two mediums, that using different controlled voltage signal between the transparent and frosted shield to freely switch, and via mixed with a binary paint, the invention can realize electric control switch between transparent and color shield (colorful or black), and via dividing electrode, the invention can display patter or word. The invention has wide application in decoration, which needs private control area and vehicle electric field, and the electric information display technical field.

Description

technical field [0001] This invention is a new breakthrough in the field of optical applications by utilizing the special properties of smectic liquid crystals. According to the photoelectric properties of this liquid crystal, products such as "electrically controlled dimming glass" or "electrically controlled dimming film" have been designed and developed, and the "fully transparent" and The transformation of "foggy frosted shading" or the transformation between "full transparency" and "colored shading", just like electric control curtains. Among them, the transformation between fully transparent and shades with a certain color is made by mixing and matching certain dyes, while the foggy frosted shades do not use dyes. Moreover, through the design of transparent electrodes and control circuits, certain patterns, patterns, and even text can be displayed on such glass or film. [0002] Therefore, the invention covers the technology and basic knowledge of optics, electronics a...

Problems solved by technology

Among them, photochromic, thermochromic and piezochromic switchable glass are greatly affected by environmental factors, so it is not a fully autonomously controlled smart switchable glass

[0004] Among the electrochromic switchable glass, there is a suspendable particle switchable glass invented and manufactured by Koreans, that is, the transmission and scattering of light can be adjusted by controlling the number of suspended particles between the two layers of glass, but the cost is expensive. Moreover, in order to prevent particle leakage, the requirements for operation and use environment are relatively high.
