Rate is crossed, sunshade effect can be functioned well as in dark-state.And the second light modulation region 4 is to meet security legislation requirement, in illuminated state
When need to have higher visible light transmittance (be greater than 70%), while high beam or towards needing under the strong illuminations such as the setting sun it is fast
Prompt drop low visible light transmitance.Using two different visible light transmittances, safety and the comfort of driving are greatly improved.
Specifically, for being located at relative position higher first light modulation region 3, in non-strong illumination, by the first light modulation
Region 3 is adjusted to the illuminated state compared with high visible light transmissivity, such as 40%, 45% or 50%, can be improved room light effect；Strong
When light irradiates, the first light modulation region 3 is adjusted into the dark-state to lower visible light transmittance, such as 1%, 2%, 3%, 4% or 5%,
It can substantially play the role of to strong light completely obscured.And it is lower by towards the setting sun, distance light light irradiation for being located at relative position
Second light modulation region 4, in non-strong illumination, by second light modulation region 4 adjust to compared with high visible light transmissivity illuminated state, such as
70%, 72%, 74% or 75%, the sight of driver is not influenced；In strong illumination, by second light modulation region 4 adjust to compared with
The dark-state of low transmission, such as 10%, 15%, 20% or 25%, have the effect of one-way viewable.Also, due to the second light modulation
Region 4 still has certain visible light transmittance in dark-state, even when there is free from glare mistuning light situation, from car
The outer scene of the vehicle seen is also than more visible, and influence so as to avoid maloperation to pilot's line of vision further improves driving
Safety.
