In the case where not needing multilayer liquid crystal light modulation film 12 while opening, only one layer of liquid crystal light modulation film 12 distributes voltage value thereto, from
And achieve the effect that singly to open one layer of liquid crystal light modulation film 12, and then extend life of product.
In four embodiments of the invention, referring to FIG. 6, it illustrates the controllers of four embodiments of the invention to control two layers of liquid
The control timing diagram of brilliant light modulation film 12.Control sequential shown in the present embodiment is ultralow transmission shown in an above-mentioned embodiment
Controller in rate long-life liquid crystal light modulation film glass 1 controls the control mode of two layers of liquid crystal light modulation film 12 (two layers of NPD), passes through
Controller can be controlled separately two layers of liquid crystal light modulation film 12 (first layer liquid crystal light modulation film 121 (NPD1), second layer liquid crystal light modulation film
122 (NPD2)) switch so that reaching in the case where not needing two layers of liquid crystal light modulation film 12 while opening and singly opening one layer of liquid crystal
The effect of light modulation film 12 (first layer liquid crystal light modulation film 121 or second layer liquid crystal light modulation film 122), so that life of product is prolonged
It is long.
Set first layer liquid crystal light modulation film 121 transmitance with its voltage change between [A1, A2], second layer liquid crystal
The transmitance of light modulation film 122 with its voltage change between [B1, B2], then two layers of superimposed transmitance of liquid crystal light modulation film 12

It can be DC12V, but be not limited thereto.Photosensitive sensor acquires external environmental light luminance information, and by collected brightness
Information sends controller to, and controller is judged according to the collected brightness data of photosensitive sensor, when extraneous brightness is high,
Controller reduces the voltage distribution of two layers of liquid crystal light modulation film 12, to reduce transmitance；Conversely, then being mentioned when external world's brightness is low
The voltage of high two layers of liquid crystal light modulation film 12 distributes, and improves transmitance.
Wherein, different transmitances is presented according to distributed voltage for first layer liquid crystal light modulation film 121, and voltage value is bigger,
Transmitance is adjustable with voltage change between section [A1, A2]；Second layer liquid crystal light modulation film 122 is presented not according to distributed voltage
Same transmitance, voltage value is bigger, and transmitance is adjustable with voltage change between section [B1, B2], therefore, two layers of liquid crystal tune
The transmitance constant interval of light film 12 is [MIN, MED, MAX], and controller is according to required transmitance to respectively to two layers of liquid crystal tune
Light film 12 is dynamically distributed.
The dynamic allocation mode of controller is that, when the rate that is required through is at the section [MIN, MED], controller need to only adjust it
In one layer of liquid crystal light modulation film 12 transmitance, such as can be the transmitance for only adjusting first layer liquid crystal light modulation film 121, can also be with
It is the transmitance for only adjusting second layer liquid crystal light modulation film 122；When the rate that is required through is at the section [MED, MAX], controller is simultaneously
The transmitance of two layers of liquid crystal light modulation film 12 (two layers of NPD) is adjusted, so that two layers of liquid crystal light modulation film 12 (single unit system) pass through
Rate is adjustable at section [MIN, MAX].
