Construction and operation, therefore be not considered as limiting the invention.
In addition, term " first ", " second " are used for description purposes only, and should not be understood as indicating relative importance or instruction
The quantity of technical characteristic.In the description of the present invention, the meaning of " plurality " is two or more, unless otherwise clearly specific
Restriction.Specific implementation of the invention is further described in more detail below in conjunction with specific embodiment:
Fig. 2 to Fig. 5 shows a kind of head-up-display system provided in an embodiment of the present invention.
Such as Fig. 2, a kind of head-up-display system provided in an embodiment of the present invention, before being used to be set to automobile or aircraft
At windshield, for being looked into convenient for driver by the need information projection to windshield to be shown in driving procedure
It sees, just can obtain driving information needed without bowing.
Head-up-display system includes:
Come back display transmitter 1, is used to emit optical image, and the display transmitter 1 that comes back includes emitting default band of light
To form the light source 11 of optical image, default band of light includes feux rouges, green light and blue light；
Reflectance coating 2 is set to windshield 3, for reflecting default band of light and default for removing in natural light
Other band of light except band of light penetrate.
Specifically, reflectance coating 2 is set to the inside of windshield 3, and the display transmitter 1 that comes back is set to windshield 3
Lower section.Reflectance coating 2 is set to the inside of windshield 3, can be easy to avoid the damage of external force such as scraping repeatedly for wiper
Reflectance coating 2 is set to fall off or damage from windshield 3.
The working principle of the head-up-display system of the present embodiment is as follows:
The driving information that shows as needed of display transmitter 1 that comes back generates optical image, and by the optical image court
Reflectance coating 2 emits, which formed by default band of light.After being projected to reflectance coating 2, by 2 primary event of reflectance coating,
Almost all enters in driver's eyes 4 of operator seat.The optical image does not pass through reflectance coating 2, reaches windshield 3
On, therefore not will cause and reflected by 3 front and rear surfaces of windshield and reflect the optical image, so that the optical image be caused to pass through
Secondary reflection enters the eyes 4 of driver simultaneously with the optical image of primary event, causes ghost phenomena.At the same time, in addition to
Natural light except default band of light can penetrate reflectance coating 2, will not be reflected by reflectance coating 2, therefore the light transmittance of reflectance coating 2
It is higher, the brightness on road surface will not be reduced, the sight of driver is influenced.
Head-up-display system provided in this embodiment has following technical effect that
Reflectance coating 2 is set on the inner surface of windshield 3, the reflectance coating 2 of the present embodiment, which has, reflects default wave band
Light and the characteristic penetrated for remaining band of light dexterously realize while reflecting the light beam for the display transmitter 1 that comes back,
In turn ensure that nature luminous energy largely passes through windshield 3.Not only it had solved virtual image ghost image but also the brightness of information of road surface will not be reduced.
Specifically, the thickness of the arbitrary portion of reflectance coating 2 is equal.The wedge type film of prior art solution ghost image has wedge type
The different parts thickness of structure, wedge type film is different, and needs to develop for the different windshield 3 of inclined degree different
Wedge type film.And the consistency of thickness of the reflectance coating 2 of the present embodiment, according to the light of natural light and the light source 11 for the display transmitter 1 that comes back
Spectrum feature, reflection, which comes back, shows the optical image of transmitter 1, transmits natural light, weight is eliminated without the thickness degree by film
Shadow can be entirely affixed on windshield 3, not influence perception, and without according to vehicle come stand-alone development reflectance coating 2, it is general
Type is strong.
Specifically, the surface of reflectance coating 2 is flat surface.The surface of the wedge type film of the prior art has taper structure, table
Face out-of-flatness when fitting in front windshield 3, influences perception.And the transmitting film of the present embodiment both may be used without having taper structure
Ghost phenomena is eliminated, the surface of reflectance coating 2 is flat surface, does not influence perception.
Specifically, light source 11 includes red light source, green light source and blue-light source, and default band of light includes feux rouges, green light
And blue light.As shown in figure 3, the wave spectrum of the light source 11 is successively are as follows: blue light 450nm ± 5nm, green light 520nm ± 10nm, feux rouges
638nm ± 5nm, reflectance coating 2 reflects the light of above-mentioned wave band, and transmits to the light of its all band, such as Fig. 4, for not
The wave spectrum of the natural light of the default band of light for being mixed with light source 11 by the reflection of reflectance coating 2, such as Fig. 5 are anti-by reflectance coating 2
The wave spectrum of rear remaining natural light is penetrated, the default band of light in natural light is reflected, and the light for being left wave band passes through reflectance coating 2.
Further, the display transmitter 1 that comes back further includes being projected to reflection for limiting default band of light with preset path
Polarization elements 5 on film 2, polarization elements 5 are set on the transmission path of default band of light.Polarization elements 5 correct default wave band
The propagation path of light improves the brightness of default band of light, so that optics shadow so that default band of light emits towards preset direction
As relatively sharp.
Specifically, polarization elements 5 include multiple optical grating constructions 51.The direction of propagation of the optical image is limited by optical grating construction
The propagation path of optical image is modified to consistent with the preset path of optical grating construction 51 by 51 arrangement angle, grating.
Further, the display transmitter 1 that comes back further includes the light-transmitting component 6 being set on polarization elements 5.The light-transmitting component
6 protection polarization elements 5, avoid the damage by external force.
The present invention also provides a kind of automobiles, including above-mentioned head-up-display system and instrument desk, head-up-display system setting
In on instrument desk.
Automobile with above-mentioned head-up-display system has new line display effect clear, promotes the effect of user's impression.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
