Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
It should be noted that it can be directly on another component when component is referred to as " being fixed on " another component
Or there may also be components placed in the middle.When a component is considered as " connection " another component, it, which can be, is directly connected to
To another component or it may be simultaneously present component placed in the middle.When a component is considered as " being set to " another component, it
It can be and be set up directly on another component or may be simultaneously present component placed in the middle.Term as used herein is " vertical
", " horizontal ", "left", "right" and similar statement for illustrative purposes only.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term " and or " used herein includes one or more phases
Any and all combinations of the listed item of pass.
Laser-projector 2 is the projector using tri- color laser light source of RGB, and three color laser light sources use tri- color laser of RGB
It carries out light combination and produces white light.The wavelength of tri-color laser, blue laser wavelength: 455nm ± 2nm, red laser wavelength:
638nm ± 2nm, green (light) laser wavelength: 520nm ± 2nm.
Filter coating is that can penetrate the light of other wavelength, but be not through the light of tri-color laser used in laser-projector
Line.Filter coating is plated to or is attached to composition filtering assembly 1 on lenticular screen.
Filter coating does not pass through the wave-length coverage of the laser of these three colors are as follows: blue light wavelength: 455nm ± 5nm, feux rouges wave
It is long: 638nm ± 5nm, green wavelength: 520nm ± 5nm.
There are three types of existence forms for the filter coating of laser, and referring to Fig. 1, first way is that the filter coating is directly plated to or is pasted
Display area on to lenticular screen, on shield glass, display case etc., i.e. plated film to shield glass are shown
Show region (driver's front region), does not have to monolithic glass all plated films.Referring to fig. 2, the second way is to be plated to the filter coating
Or it is attached to the glass that monolith on front windshield or display case is used to show information.The third mode be filter coating be plated to or
It is attached to transparent glass or engineering plastics in front of driver on console for independently showing.
It is adapted to different light source projects environment, route of the also settable reflecting mirror for laser light source changes.
The reflecting mirror is that the image for coming out miniature laser projector is reflected into windshield before automobile, or filters
Film, or post/be coated with the reflecting mirror on glass/light-passing plastic of filter coating.
Display application on automobile: the filter coating of laser, which can all end the light that laser light source issues, to be passed through, i.e.,
Work as laser-projector, is coated with the automobile front wind screen of laser filter coating as light that miniature laser projector issues is reflected into through reflecting mirror
After glass, the light beam of light source cannot be by the windshield, so that clearly image is formed, referring to Fig. 3.Because of the optical filtering of the laser
The light that film can only allow laser light source to issue does not pass through shield glass, has no effect on visible light and passes through automobile front wind screen glass
Glass, so will not influence the sight of motor vehicle operators.It but since the optical maser wavelength of laser light source used is shorter, and is three colors
RGB laser, thus formed image be color image, than current automobile thus monochrome image display effect it is richer, and compare
Ordinary light source brightness is high.
The display application of display case: filter coating is plated on the glazing plate of monolith, then with three color laser projection instruments
By (referring to fig. 4), which is equivalent to one piece of curtain on the glass of laser projection to plated film, picture can be shown above, supplied
Visitor's viewing, since the light of projector is not passed through glass, can form clearly pattern on coated glass, and
Brightness is high.When not using the function, which is not different with normal glass, can normal use.In this way, the plating laser is filtered
The glass of light film can not only be used when curtain, also served as the glass use for normal hyaline, enriched using function, to viewer
For, it also will be a novel function, and obtain liking for viewer, and enrich life.
The present invention cooperates laser light source to use by the way that plated film on glass to be matched to the filter coating of optical maser wavelength, reaches one
The effect that the picture that kind laser light source generates can be shown on transparent glass, is applied to automobile head-up display system, improves
Clarity and colorfulness will have biggish promotion plus experience to driver, show aspect for glazing plate, make cupboard
Window transparent glass has the function of curtain, enriches using effect, provides the diversity that laser display uses.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection scope of the claims in the present invention
Within.
