Abstract
The present invention relates to HUD technical field, particularly to a kind of wedge film eliminating HUD ghost image, it can will be included wedge film main body (100) by nanotechnology and be arranged on some wedges (101) integrated molding of described wedge film main body (100) end face, can realize filming produce, it is achieved can at automotive windshield film on surface thus reach eliminate HUD figure ghost image purpose.Owing to the present embodiment uses nanostructured, final wedge film thickness will not change along with wedge angle change so that it is more convenient that big wedge angle realizes.Therefore application the present embodiment can reduce the HUD requirement to automobile wind shield glass, have only to just can reach to eliminate the purpose of HUD ghost image at the film on surface of common windshield, without custom-made special glass, reduce the HUD requirement to automobile wind shield glass, also reduce HUD cost.
Description
Technical field
The present invention relates to HUD technical field, particularly to a kind of wedge film eliminating HUD ghost image.
Background technology
HUD (Head Up Display, HUD), is generally to use flight auxiliary machine on aircraft at present
Device, the information such as flight parameter, aiming attack, Autonomous test can with image, the form of character, be projected by it by optics
On electro-optical display device on passenger cabin dead ahead compound glass.Along with the skill of science and technology is fast-developing, HUD has been applied
On car, market also has and sells independent HUD.
When in use, main frame projects the light of image to traditional vehicle-mounted head-up display, is dividing after windshield
Being cleaved at least two bundles, light enters human eye after reflecting via the inner and outer surfaces of windshield respectively, and the actual impression at human eye is exactly
Occur in that ghost image.Not only affect user's identification to image, during driving a car, be also easy to that potential safety hazard occurs.
In order to solve the problem of ghost image, existing HUD manufacturer provides two solutions, and one is existing
The front dress HUD of luxurious car, uses double-layer glass structure at its windshield, and it is special to utilize between layer glass
Technique embeds the PVB interlayer of wedge shape, and the image making glass surfaces externally and internally reflect is overlapped into an image, solves lacking of ghost image
Fall into.And after at present dress be by the dark reflectance coating of patch, reduce ghost image by the brightness increasing main picture, the brightness that reduces pair picture
Impact, does not actually have any improvement, and dark film can affect driver at night and observe front road conditions, there is fraud ghost image
End.
Wedge film in existing front entrucking has thin one end and thick one end, also has certain angle, wedge film
Angle needs to arrange according to the requirement of HUD.
Existing wedge film has higher requirement on projection distance, in any case adjust, there is wedge shape thickness all the time
It is too many that one end exceedes thin one section, causes wedge film thickness excessive, when applying this wedge structure to front windshield, at glass
After molding, it is difficult to implement, can only be prefabricated in front entrucking type, therefore cannot popularize, more be difficult to make in rear dress pad pasting market
With.
Summary of the invention
Embodiment of the present invention goal of the invention is to provide a kind of wedge film eliminating HUD ghost image, applies this technology
Scheme can realize eliminating the effect of HUD ghost image, and thickness is little simultaneously, applies more extensive.
In order to realize foregoing invention purpose, the complete skill scheme of the present invention is:
A kind of wedge film eliminating HUD ghost image, including wedge film main body (100) and be arranged on described wedge shape
Some wedges (101) of film main body (100) end face.
Preferably, the cross section of described wedge (101) is right angled triangle；Described right angled triangle includes the first right angle
The angle (a) of limit (i), the second right-angle side (d) and hypotenuse, the first right-angle side and hypotenuse.
Preferably, a length of 0.2 millimeter～1 millimeter of described first right-angle side (i).
Preferably, the numerical value of described angle (a) is 0.01 °～0.1 °.
Preferably, the cross section of described wedge (101) is obtuse angle obtuse triangle upward；Described obtuse triangle bag
Include the angle (b) on the first limit (j), the second limit and the 3rd limit, the first limit (j) and the second limit.
Preferably, a length of 0.2 millimeter～1 millimeter of described first limit (j).
Preferably, the numerical value of described angle (b) is 0.01 °～0.1 °.
Preferably, the numerical value at described obtuse angle is 140 °～160 °.
Therefore, apply the present embodiment technical scheme, by arranging some wedges at wedge film body top face, logical
Crossing some independent wedges to realize eliminating ghost image, wedge angle is not limited by this structure due to thickness simultaneously, makes this
Bright embodiment is more widely applied, and is suitable for almost all HUD market.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, also may be used
To obtain other accompanying drawing according to these accompanying drawings.
The structural representation that Fig. 1 provides for the embodiment of the present invention 1；
The structural representation that Fig. 2 provides for the embodiment of the present invention 2.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Embodiment 1:
As it is shown in figure 1, the present embodiment provides a kind of wedge film eliminating HUD ghost image, including wedge film main body
100 and be arranged on some wedges 101 of wedge film main body 100 end face.
The cross section of wedge 101 is right angled triangle；Right angled triangle include the first right-angle side i, the second right-angle side d and
The angle a of hypotenuse, the first right-angle side and hypotenuse.A length of 0.2 millimeter～1 millimeter of first right-angle side i.The numerical value of angle a is
0.01 °～0.1 °.When realizing the effect eliminating ghost image of the embodiment of the present invention, the numerical value of the second right-angle side d approximates 0.
