5) antiultraviolet film：One kind is capable of the plastic foil of cutting off ultra-violet ray (ultraviolet abbreviation UV)；Ultraviolet, is divided into true
Sky, shortwave, medium wave, long wave, four kinds of myriametric wave.Ultraviolet refer to electromagnetic spectrum medium wavelength from 10nm~400nm radiate it is total
Claim；Ultraviolet can be used to sterilize, and excessive ultraviolet enters can cause cutaneum carcinoma to human body in vivo.
It should be noted that liquid crystal 9 is dichroic dye liquid crystal.Using dichroic dye liquid crystal light valve as transmitting device
Part, the response speed being changed into from state of (high transmission state) under dark-state (low transmission state) normal temperature is less than 20msec；Using sensor devices
Drive circuit automatically adjusts the transmitance of the transmission liquid crystal layer of light, and dark-state transmitance is less than 13%, reduces light to driver's eye
The stimulation of eyeball, improves drive safety；Transmitance during on state of does not influence transparent effect more than 70%；According to the strong of ambient light
It is weak, automatically adjust the transmitance 13%~70% of light.
The present invention is not limited to above-mentioned preferred forms, and those of ordinary skill in the art may be used under enlightenment of the invention
Other various forms of products are drawn, however, make any change in its shape or structure, it is every with same as the present application
Or close technical scheme, it is within the scope of the present invention.
