The inventors of the present application have conducted research and found that the conventional dimming glass schemes on the market include PDLC (polymer dispersed liquid crystal), EC (electrochromic) and SPD (suspended particles), and although technical indexes have respective advantages and disadvantages, the overall functions cannot perfectly match the market requirements, and thus the dimming glass schemes are not widely used. The PDLC dimming glass is transparent when being powered on and is in a fog state when being powered off, and the application scene of the PDLC is limited due to the fact that the haze is large, so that the PDLC dimming glass is suitable for being applied to meeting room partitions and cannot be widely applied to automobile and building glass. The EC principle is that the color change and dimming are realized through oxidation-reduction reaction, but the response speed is slow (5 min/square meter), and the larger the glass size is, the slower the color change is, the phenomenon of nonuniform color change is easy to occur, and the method is not suitable for large-size scenes. The operating voltage of the SPD light control glass is as high as 110V, and there is a fear of safety risk, so that the application in the automobile and building glass is greatly limited.
Compared to the above dimming scheme, the liquid crystal LC dimming scheme: under the drive of voltage, the dye molecules can be controlled to rotate to change the transmittance, so that the continuous adjustment of bright and dark states is realized. The dye liquid crystal dimming scheme has the following advantages:
1. stepless dimming, second-level response, low dark state transmittance below 1 percent, and privacy prevention function
2. Energy conservation and consumption reduction: the driving voltage is low (less than 12V), and the power consumption is 2 w/square meter;
3. high permeability: no haze and no visual angle problem;
4. the control is flexible: the system can be automatically/manually controlled, and can also realize remote network control through an App;
5. the size and shape are customized.
The dye liquid crystal dimming device has the effects of sound insulation, heat insulation and ultraviolet resistance by matching with a car window industrialization scheme, is particularly suitable for automobiles, rail transit, daylighting roofs and curtain wall scenes, and can be well integrated in application scenes such as passenger cars, building glass and the like.
