Specific embodiment

Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work The every other embodiment obtained, fall within the protection scope of the utility model.

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 are led with the technology for belonging to the utility model The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes Any and all combinations of one or more related listed items.

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 utility model 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 The effect that the picture generated to a kind of laser light source can be shown on transparent glass, is applied to automobile head-up display system, mentions High clarity and colorfulness, will have biggish promotion plus experience to driver, and show aspect for glazing plate, So that show window transparent glass is had the function of curtain, enrich 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 of the utility model claims Within the scope of.
