By the high refracting layer of reasonable design and the film material and thicknesses of layers of forming low-refractive-index layer, enable to described transparent
Nanometer film layer 3 has outstanding machinery, chemically and thermally stability.
Certainly, in some other embodiment, the transparent nano film layer 3 can include three, the height of four or more
The laminated construction of refracting layer/forming low-refractive-index layer, and adjustment is optimized to each high refracting layer, the material of forming low-refractive-index layer and thickness, with
Meet practical application request.
The thickness of the interior glassy layer is not more than 3mm, preferably no greater than 1.6mm, and the thickness of inner layer glass directly affects into
As effect.
The middle diaphragm 22 is 2%~15%, preferably 3%~12% to the absorptivity of P polarization light.Absorptivity is less than
2% can form obvious ghost image, and absorptivity is more than 15% transmitance that can significantly reduce extraneous light so that imaging picture
The definition in face is difficult to reach observation demand.
In certain embodiments, the thickness of the middle diaphragm 22 is 0.3~3.0mm, is included in the middle diaphragm 22
There is the composition that there is absorption to P polarization light, the composition is ester, alcohol, ether, ketone, alkene, benzene, aldehyde, at least one in halogenated hydrocarbon
Kind.
Preferably, the middle diaphragm 22 is optional has some to have the pvb film of specific function so that it possesses accordingly
The functions such as heat-insulated, sound insulation, antiultraviolet.
The refractive index of the outer glassy layer 23, the interior glassy layer 21 and the middle diaphragm 22 is no more than 0.2.Experience
Card, when the refractive index of the outer glassy layer 23, the interior glassy layer 21 and the middle diaphragm 22 is more than 0.2, imaging process
In easily form obvious ghost image.
It refer to shown in Fig. 4, Fig. 4 shows a kind of imaging schematic diagram of head-up-display system, and the display system includes light
Source 1 and provided by the utility model come back show front windshield, and its specific image-forming principle is as follows：
Light source 1 is used to produce P polarization light 11, and P polarization light 11 is incident to the table of the interior glassy layer 21 at an angle
On face, after the refraction of interior glassy layer 21, P polarization light 11 reaches the transparent nano film layer 3 and the middle film layer 22, now portion
P polarization light 11 is divided to form refracted light 12 through the transparent nano film layer 3 and the middle film layer 22.Due to transparent nano film
The reflectivity of 3 pairs of P polarization light 11 of layer is higher, therefore remaining P polarization light 11 is through the metal level in the transparent nano film layer 3
Refracted light 14 is reflected to form, refracted light 14 is to produce the main picture 18 required for driver.
In imaging process, it is strong that low-surface-energy film layer 24 can effectively strengthen reflection of the transparent nano film layer 3 to P polarization light 11
Degree, so as to lift the intensity of refracted light 14, finally makes winner be become apparent from as 18.
At the same time, when refracted light 12 is by the interface of air and outer glassy layer 23, a portion refracted light
12 generation refractions form refracted light 17, and refracted light 17 projects can't cause vision to disturb driver outside car, remainder
Point refracted light 12 light 15 is reflected to form by the surface of outer glassy layer 23, reflection light 15 is through middle film layer 22 and transparent
Nanometer film layer 3, when by the intersection of interior glass plate 21 and air, reflection light 15 produces refraction and forms refracted light 16,
Refracted light 16 can form ghost image 19 in the car.
Because middle film layer 22 reaches 2%~15% to the absorptivity of P polarization light, therefore, when reflection light 15 passes through institute
It can be weakened severely when stating middle film layer 22, so that the intensity of refracted light 16 is very low, imaging ghost image caused by it
19 are difficult to have an impact driver so that driver can be absorbed in main picture 18.
When the incidence angle of P polarization light 11 is 50 °~72 ° of high incidence angle, ghost image has the trend of enhancing, therefore requires
Middle film layer 22 strengthens the absorbability of P polarization light 11, it is therefore preferred that middle film layer 22 needs to the absorptivity of P polarization light
Reach 3%~10%.
