Specific implementation mode
Double-sided display window film is a kind of novel glass display technical products, its film bulk structure includes：Imaging substrate
Liquid crystal molecule material, regular reflection material layer, tin indium oxide (ITO) conductive material, polymer dispersion liquid crystal material (PDLC) material
Material, core membrane body thickness are 0.75 millimeter.Membrane body is attached on any glass through control device (alternatively referred to as wisdom box control
System processed) and can realize two-sided while show video, photo-document in conjunction with any type projection device.Double-sided display window film is every
Square metre electrical power consumed there was only 4W (alternating current).Double-sided display form (film) is attached on glass, wisdom box control system is passed through
Automatic or remote control double-sided display window film moment realizes imaging, transparent, misty and four kinds of states of translucent imaging, daytime glass
Glass can be changed to all-transparent state or mist, become the effect of electronics curtain, be sent out at night to projection device by wisdom box control system
Go out order, glass moment becomes super large two-sided display screen.Double-sided display window film is widely used in that outdoor, indoor various show windows are saturating
Bright glass；Solves the technical issues of commercial glass show window perplexed always becomes two-sided display screen.
Technical solution of the present invention is described in detail with reference to the accompanying drawings and examples.
Referring to FIG. 1, the double-sided display window film of the embodiment of the present invention includes：Imaging layer 21, the first conductive layer 22, liquid crystal
Molecular layer 23, the second conductive layer 24 and reflective layer 25；The layer of liquid crystal molecule 23, which is located at first conductive layer 22 and second, leads
Between electric layer 24；First conductive layer 22, layer of liquid crystal molecule 23 and the second conductive layer 24 are located at the imaging layer 21 and reflective
Between layer 25；The material of the imaging layer 21 is polymer dispersion liquid crystal material, and the material of the reflective layer 25 is regular reflection
The material of material, first conductive layer, 22 and second conductive layer 24 is tin indium oxide conductive material.
When practical application, the film bulk structure of double-sided display window film is followed successively by pdlc film, ITO conductive films, liquid crystal film, ITO
Conductive film and regular reflection material membrane.
Pdlc film is a kind of novel building materials (being referred to as light modulation film), is mainly used for electronics interception and (is commonly called as electronic window
Curtain), containing micro liquid crystal molecule and metallic molecule material, it is mainly used for blocking sunlight, and liquid crystal molecule therein contains
Amount is smaller, if matched with the imaging of the projection light source of projection device, the effect of three primary colours (RGB) imaging is very bad；Generally
For, pdlc film also can be used to by the liquid crystal molecule of itself as projection screen, and only imaging effect is bad, so
It can not apply.And the present embodiment intermediate layer of liquid crystal molecule it is practical be exactly to have made a special interlayer of imaging, to reach imaging
The good purpose of effect.ITO conductive films are the interlayers of intermediate liquid crystal molecule, two-sided positive and negative anodes power supply, it is therefore necessary to use two layers
Conductive film.
Further, since projection pattern is back projection image-forming principle, that is to say, that membrane body is positive imaging, using regular reflection
The purpose of material layer is exactly to play the role of picture to be refracted to the back side simultaneously.Regular reflection material membrane (layer) is similar to reflective unidirectional
Perspective film, but its reflectivity and transmitance are distinguishing.
Further, the double-sided display window film further includes：It is regarded with what first conductive layer and the second conductive layer were connect
Fenestrated membrane input interface.With continued reference to FIG. 2, the liquid crystal film in double-sided display window film contains liquid crystal molecule, it is unordered when being not powered on
Ordered state, as shown in (a) of Fig. 2, the transparent effect of double-sided display window film is low at this time, and window film presents misty (impermeable
It is bright).There are conductive layer (conductive film) in liquid crystal molecule both sides, when the positive and negative anodes by the window film input interface are respectively to liquid crystal point
When the both sides conductive layer of son provides electric current (such as alternating voltage 48V), liquid crystal molecule is ordered arrangement state, such as (b) institute of Fig. 2
Show, pellucidity is presented in double-sided display window film at this time.
Double-sided display window film has the following advantages：(1) energy saving；Every square metre of comprehensive power consumption only has 4W；(2) ring health care
Health, without any harm ray, uvioresistant, infrared ray etc. are to the harm ray of human body, especially to eyes fanout free region；(3) make
With service life height, product service life was up to -35 ten thousand hours 300,000 hours；(4) at low cost, every square metre of initial investment cost is only
Hundreds of yuan, and it is extremely low using operating cost；(5) human-computer interaction function, this product can be loaded into multipoint-touch-technology, body-sensing camera shooting skill
The various human-computer interaction function technologies such as art, acoustic control remote sensing technology, there is very strong software interaction function；(6) simple installation is pasted onto
On simple glass just can be used, without any environmental requirement, and can it is customized according to user's actual conditions, freely cut, very
It is convenient.(7) waterproof, high-low temperature resistant.
Double-sided display window film is and a kind of approximate imaging product of existing holographic imaging optical film, holographic imaging optics
Film is a kind of cold film, is similar to automobile shading film.Holographic imaging optical film is by the other nanocomposite optical component of molecular level：
Full figure color filter crystalline solid (HCFC) is core material, merges nanotechnology, the multidisciplinary achievement such as optics, macromolecule and system
Standby processing technology produces frivolous inside and contains elder generation using organic material, inorganic nanometer powder and fine metal powder as raw material
Into precision optics structure image-forming principle.Its thickness is 0.1 millimeter.
The common ground of holographic imaging optical film and double-sided display window film：A, all it is to realize to image by projector；B, all
The product of display function could be realized by being attached on glass.
The difference of holographic imaging optical film and double-sided display window film：A, double-sided display window film is to pass through low-voltage alternating-current
Electricity activates the principle of liquid crystal molecule to realize imaging, and holographic imaging optical film is to realize imaging by the principle of optical reflection
's；That is double-sided display interaction window film is switched on product, and holographic imaging optical film is no power product；Its operation principle
It is entirely different.B, double-sided display window film can two-sided imaging simultaneously；And holographic imaging optical film can only one side show.C, two-sided
Display window film can realize all-transparent, imaging under energization, hide the functional status such as black, suspension imaging, you can when electronics curtain
Display screen can be worked as again；And holographic imaging optical film is then without this function.D, the display effect of double-sided display window film such as resolution ratio, clear
Clear degree, contrast are significantly larger than holographic imaging optical film.E, double-sided display window film can be loaded into multipoint-touch-technology, body-sensing is taken the photograph
As various human-computer interaction function technologies such as technology, acoustic control remote sensing technologies；There is very strong software interaction function；And holographic imaging optics
Film is without this function.F, the service life of double-sided display window film is up to -35 ten thousand hours 300,000 hours, holographic imaging optical film
Service life only has -5000 hours 3000 hours.
