Abstract
The present invention relates to the technical field of display, especially relates to laminated glass in a vehicle and a head up display system thereof, and particularly relates to a head-up display laminated glass capable of adapting to a high incidence angle and a head-up display system comprising the laminated glass. The head-up display laminated glass comprises an inner glass plate, an outer glass plate, and a middle film which is clamped between the inner glass plate and the outer glass plate. The refractive index difference of a high refractive index layer and a low refractive index layer is larger than or equal to 0.5. The middle film can absorb 2% to 18% P polarized light. According to the head up display laminated glass and the system, the P polarized light is absorbed through the middle film, the intensity of the P polarized light which goes through the middle film is weakened, thus secondary image brightness is reduced, no ghosting of the P polarized light in an incidence angle 50 to 68 degrees is realized, no ghosting of the P polarized light in an incidence angle 50 to 72 degrees is realized, even no ghosting of the P polarized light in an incidence angle 50 to 75 degrees is realized, and the head up display laminated glass can be completely adapted to the head up display requirement of a high incidence angle.
Description
Technical field:
The present invention relates to new line Display Technique field, particularly relate to the laminated glass on automobile and head-up-display system thereof, specifically
Ground is a kind of new line display laminated glass that can adapt to high angle of incidence and the head-up-display system including this laminated glass.
Background technology:
Along with people are more and more higher to the requirement of driving safety, display (HUD, the Head Up Display) system that comes back is by increasingly
How use on automobile.General automobile front windshield is laminated glass, and it is the glass by least two panels with certain curvature
In the middle of glass substrate, sandwiched intermediate polymer diaphragm (such as polyvinyl butyral resin i.e. PVB) is constituted, the projection light source of head-up-display system
The light sent can reflect through two surfaces of laminated glass with air contact, and the reflected image on two surfaces can produce
Offset thus form two ghost images interfered, particularly in the case of the thickness thicker (generally more than 3mm) at laminated glass
Can become apparent from, this greatly limits the definition of projection-display image.
For solving the ghost problems of head-up-display system on shield glass, prior art exists some schemes, main
Have following several:
The first, use wedge shape PVB scheme, is also the most ripe commercialization HUD solution, such as patent
It is to use that CN101038349 (A), US2002172804 (A1) and US2007148472 (A1) disclose a solution therein
The polymer membrane of wedge shape is as the intermediate layer of laminated glass so that the wedge shaped change of the upper and lower thickness of laminated glass, so that driving
The reflected image on two surfaces that the person of sailing sees essentially coincides, and eliminates ghost problems the most significantly；This technical scheme exists
Following shortcoming: 1, fail thoroughly to eliminate ghost image, be not suitable for high-definition image and show；2, need to use the pvb film of special requirement,
Its price is 7～10 times of common pvb film, and technology difficulty is high so that material and process costs are the highest；3, to vehicle
Optical design is sensitive, need to redesign for the windshield of concrete vehicle；Similarly adopt with above-mentioned wedge shape PVB scheme
With such disclosed in the glass substrate of local wedge thickness, such as patent US6414796 (B1), similarly there is also and be not suitable for height
Clear image show, technology difficulty is high, cost height and the shortcoming such as universality is poor；
The second, the surface of laminated glass or middle arrange can change direction of polarized light optical functional layer or can reflected P
Polarized light or the reflective polarizer of S-polarization light, and the P polarization light that sends of the projection light source combining head-up-display system or S-polarization
Light is incident with special angle (such as Brewster's angle), thus utilizes laminated glass to the reflection characteristic of different polarization light to disappear as far as possible
Except the reflected image on certain surface, finally eliminate ghost image.This technical scheme EP0836108 (A2), EP0844507 (A1),
US6327089(B1)、CN1969219(A)、US7355796(B2)、CN101151568(A)、US7839574(B2)、
The patents such as CN1732404 (A) and CN102256910 (A) all have disclosure, but the premise that this technical scheme realizes is must be
Extra optical functional layer or reflective polarizer are set up in the local (i.e. come back display view field) of laminated glass, and this most necessarily improves
Material cost and technology difficulty, such as the multiple layer polymer P polarization reflecting mirror number of plies disclosed in CN1732404 (A) is the most tens of
To hundreds of layers；The overall homogeneity of windshield is also destroyed simultaneously, reduces aesthetics；Additionally, local sets on laminated glass
The adhesion strength in the region putting optical functional layer or reflective polarizer may reduce thus cause potential safety hazard；And, partial optical
The visible light transmissivity of functional layer or reflective polarizer is on the low side, thus the visual field of driver or the outward appearance of windshield are produced impact；
The third, can also reduce naked eyes by the way of strengthening the reflection light formed on the laminated glass surface with air contact
Adhesive film type HUD projector common on visible ghost phenomena, such as component market, it is to paste in advance in HUD view field
Semi-transparent reflective film；Or as patent US6137630 (A) discloses the multilayer dielectricity layer replaced by high and low refractive index material
It is deposited on a surface of laminated glass and air contact, thus strengthens the intensity of the reflection light of contact surface, and another one
Intensity of reflected light on surface is basically unchanged, and the reflected image therefore enabling human eye observe mostlys come from the reflection of coated surface
Light.Obviously, on the one hand this technical scheme destroys overall homogeneity or the permeability of outward appearance, the opposing party of automobile front windshield
Face is not inherently eliminated ghost phenomena yet.
Although above-mentioned several solution inhibits ghost problems to a certain extent, but is confined to angle of incidence field below 70 °
Scape uses, and during for high angle of incidence such as higher than 72 °, above-mentioned solution yet suffers from more significantly ghost problems.Along with
The established angle of front windshield is required more and more higher by people, and the requirement of the projected light angle of incidence of head-up-display system is the most more come by it
The biggest, angle of incidence possibly even reaches 75 °, and along with the increase of angle of incidence, the ghost problems of the display projection imaging that comes back is also
Can be increasingly severe, solve the most more and more difficult, the most above-mentioned solution can not fully meet high angle of incidence well
Come back display demand.
Summary of the invention:
The technical problem to be solved is the shortcoming existed for above-mentioned prior art, it is provided that one can be clear
