Description
Technical field：
The present invention relates to new line display technology field, the more particularly to laminated glass on automobile and its display system that comes back
Unite, specifically a kind of new line that can adapt to high incidence angle shows that laminated glass and the new line including the laminated glass are shown
System.
Background technology：
Requirement more and more higher with people to driving safety, comes back and shows (HUD, Head Up Display) system quilt
Used more and more on automobile.General automobile front windshield is laminated glass, and it is that had necessarily by least two panels
Sandwiched intermediate polymer diaphragm (such as polyvinyl butyral resin is PVB) is constituted in the middle of the glass substrate of curvature, head-up-display system
The light that sends of projection light source by laminated glass and air contact two surfaces when can reflect, it is anti-on two surfaces
Projection picture can produce skew to form two ghost images interfered, and particularly the thickness in laminated glass is thicker (general super
Cross 3mm) in the case of can it is more obvious, this greatly limits the definition of projection-display image.
To solve the ghost problems of head-up-display system on shield glass, there are some sides in the prior art
Case, mainly there is following several：
The first, is also the commercialization HUD solutions of current more maturation, such as patent using wedge-shaped PVB schemes
It is to adopt that CN101038349 (A), US2002172804 (A1) and US2007148472 (A1), which disclose a solution therein,
With intermediate layer of the wedge-shaped polymer membrane as laminated glass so that the wedge shaped change of the upper and lower thickness of laminated glass, so that
The reflected image on two surfaces that driver sees is essentially coincided, and finally significantly eliminates ghost problems；The technical scheme
Have the disadvantage that：1st, fail thoroughly to eliminate ghost image, be not suitable for high-definition image and show；2nd, the PVB films using special requirement are needed
Piece, its price is 7~10 times of common pvb film, and technology difficulty is high so that material and process costs are very high；3rd, to vehicle
Optical design it is sensitive, need to be redesigned for the windshield of specific vehicle；With above-mentioned wedge-shaped PVB schemes similarly
Using the glass substrate of local wedge thickness, such as patent US6414796 (B1) is open, similarly there is also be not suitable for
High-definition image is shown, technology difficulty is high, cost is high and the shortcomings of poor universality；
Second, the surface of laminated glass or it is middle set can change direction of polarized light optical functional layer or can
The reflective polarizer of reflected P polarized light or S-polarization light, and combine P polarization light or S that the projection light source of head-up-display system is sent
Polarised light is incident with special angle (such as Brewster's angle), so that using laminated glass to the reflection characteristic of different polarization light with to the greatest extent
The reflected image on some surface may be eliminated, ghost image is finally eliminated.This technical scheme is in EP0836108 (A2), EP0844507
(A1)、US6327089(B1)、CN1969219(A)、US7355796(B2)、CN101151568(A)、US7839574(B2)、
There is disclosure in the patent such as CN1732404 (A) and CN102256910 (A), but the premise that this technical scheme is realized is necessary
Extra optical functional layer or reflective polarizer are set up in the part (come back show view field) of laminated glass, this is just inevitable
Improve the multiple layer polymer P polarization speculum number of plies disclosed in material cost and technology difficulty, such as CN1732404 (A) high
Up to tens of to hundreds of layers；The overall homogeneity of windshield is also destroyed simultaneously, reduces aesthetics；In addition, on laminated glass
The adhesion strength in the region of local setting optical functional layer or reflective polarizer may reduce to cause potential safety hazard；Moreover,
The visible light transmissivity of partial optical functional layer or reflective polarizer is relatively low, so that the visual field or windshield to driver is outer
See and produce influence；
The third, can also be subtracted by way of strengthening the reflected light formed on the surface of laminated glass and air contact
Common adhesive film type HUD projectors on few macroscopic ghost phenomena, such as component market, it is pre- in HUD view fields
First paste semi-transparent reflective film；Or as patent US6137630 (A) discloses that high and low refractive index material is alternately more
Layer cvd dielectric layer is on a surface of laminated glass and air contact, so that strengthen the intensity of the reflected light on contact surface,
And the intensity of reflected light on another surface is basically unchanged, therefore the reflected image for enabling human eye to observe mostlys come from plating
The reflected light on film surface.Obviously, on the one hand this technical scheme destroys the overall homogeneity or outward appearance of automobile front windshield
Permeability, is not on the other hand also inherently eliminated ghost phenomena.
Although above-mentioned several solutions inhibit ghost problems to a certain extent, be confined to incidence angle 70 ° with
Under scene use, during for high incidence angle for example higher than 72 °, above-mentioned solution still has more significant ghost image and asked
Topic.As people require more and more higher to the established angle of front windshield, its projection angle of light to head-up-display system
It is required that also increasing, incidence angle possibly even reaches 75 °, and with the increase of incidence angle, comes back and show projection imaging
Ghost problems also can be increasingly severe, and solution gets up also more and more difficult, therefore above-mentioned solution can not be complete well
Meet the demand of the new line display of high incidence angle.
