Description
Technical field
The present invention relates to a kind of projection display systems, more particularly to a kind of ultra-thin anti-light projection display system.
Background technique
There are many display modes at present in the market, it is main especially in terms of extra large screen, such as in 100 cun or more of screen
Want technology for projection and LED screen technology.LED occupies mainstream on large-size screen monitors are shown, especially outdoor large-size screen monitors are even more so.Project skill
Art, which has been mainly brightness lower limit, to be developed.
The operating distance of shadow casting technique is bigger, and required space is bigger, and many times not many spaces
It can use.If in addition shadow casting technique is thrown using positive, projector is external, and many occasions are simultaneously improper.Such as public arena,
There is theft risk.And if projector distance first is bigger using rear-projection, back space requirement is very big, very occupied space.
Secondly it requires in terms of brightness also higher, when projection, if ambient light is higher, in the case that contrast is not high enough, is then imaged non-
It is often gloomy.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of ultra-thin anti-light projection display systems, solve Current projection system
The problem that projector is external, occupied space is big and display is gloomy.
The present invention is to solve above-mentioned technical problem and the technical solution adopted is that provide a kind of ultra-thin anti-light Projection Display system
System, including shell, projector, reflective mirror and the compound curtain of rear-projection；The shell is hollow structure, is display before the shell
Face, the compound curtain of rear-projection are embedded in display surface center；It is reflective surface behind the shell, the reflective mirror is mounted on
Before enclosure interior reflective surface, the projector is mounted on bottom in shell or is lifted on shell inner top；The projector is
Ultra short focal projector, close to the compound curtain of rear-projection, the camera lens arrives the camera lens of the projector backwards to the compound curtain projecting beam of rear-projection
On reflective mirror, on the mirror reflection light beam to the compound curtain of rear-projection.
Further, the compound curtain of the rear-projection includes protective layer and imaging layer, and the imaging layer is positioned close in shell
Side, the protective layer is arranged in hull outside.
Further, the protective layer is glass or two layers of insulating glass unit.
Further, glue-line is equipped in described two layers among glass plate.
Further, the imaging layer bonds or is adsorbed on the surface of protective layer
Further, the imaging layer includes film layer, and the film layer is plastic film.
Further, the film layer is diffusion barrier, and the diffusion barrier scatters light, diffusing light amendment diffusion
Angle simultaneously expands angular field of view, and the angular field of view of the diffusion barrier is 0-180 °.
Further, the shell inner surface is set as black, the shell inner surface all covering black flocking.
The present invention compare the prior art have it is following the utility model has the advantages that ultra-thin anti-light projection display system provided by the invention,
All component installations in the housing, are installed simple and reliable；Back projecting system occupied space reduces, i.e., the vertical range after screen is wanted
It asks and greatly reduces, the scope of application is more extensive；Screen film layer effect keeps screen intensity higher, and does not have effect of sunlight, comparison
Degree is high, there is better viewing effect；Screen prevents screen from scratching using glass panel as protective layer, and double-layer structure is sturdy and durable.
Detailed description of the invention
Fig. 1 is ultra-thin anti-light projection display system structural schematic diagram in the embodiment of the present invention.
In figure:
1 shell, 2 projector, 3 reflective mirror
4 protective layer, 5 imaging layer, 6 camera lens
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is ultra-thin anti-light projection display system structural schematic diagram in the embodiment of the present invention.
Referring to Figure 1, ultra-thin anti-light projection display system in the embodiment of the present invention, including shell 1, projector 2, reflective mirror
3 and the compound curtain of rear-projection；The shell 1 is hollow structure, is display surface before the shell 1, the compound curtain of rear-projection is inlayed
It is reflective surface behind display surface center, the shell 1, before the reflective mirror 3 is mounted on 1 inside reflective surface of shell,
The projector 2 is mounted on bottom in shell 1 or is lifted on 1 inner top of shell；The projector 2 is ultra short focal projector,
The camera lens 6 of the projector 2 close to the compound curtain of rear-projection, the camera lens 6 on the compound curtain projecting beam to reflective mirror 2 of rear-projection,
In 2 the reflected beams of reflective mirror to the compound curtain of rear-projection.The benefit of this arrangement is exactly that the projection ratio of original ultrashort coke again may be used
To be reduced to nearly one times, entire projector and the occupied space of system are very thin also very limited, just have in many occasions
A possibility that application.
Ultra-thin anti-light projection display system provided by the invention, the compound curtain of rear-projection include protective layer 4 and imaging layer 5,
The imaging layer 5 is positioned close to the side in shell 1, and the setting of protective layer 4 is in 1 outside of shell.4 material of protective layer
One layer of air is pressed from both sides for glass, layer glass or layer glass presss from both sides one layer of glue.The advantage of doing so is that can both prevent screen from drawing
Wound, and picture can be made graceful as among picture frame.The bonding of imaging layer 5 or the surface for being adsorbed on protective layer 4.
Ultra-thin anti-light projection display system provided by the invention, the imaging layer 5 include film layer, and the film layer is that plastics are thin
Film；The film layer is diffusion barrier, and the diffusion barrier scatters light, and diffusing light simultaneously corrects diffusion angle, by light
It is soft uniformly to disseminate out.Diffusion barrier makes light generate scattering, and maintains certain distribution, so that the viewing of screen
Angle becomes larger, and the angular field of view of the diffusion barrier is 0-180, in biggish angle or can watch.Light is spread simultaneously
Also eliminate solar effect, i.e. the entire brightness of screen is simultaneously uneven in viewer.The design of film layer further comprises pair
The considerations of light efficiency, i.e., most optics can pass through screen and reach in the eye of viewer, rather than be blocked.
Ultra-thin anti-light projection display system provided by the invention is set as completely black inner cavity, the shell 1 in the shell 1
Interior all setting black flocking in addition to the compound curtain position of rear-projection.In internal system, it will not be influenced by stray light and reduce comparison
Degree.Special extraneous light is incident on after screen, after passing through screen, can also be absorbed by back cavity in internal system, that is,
Influence of the environment light to screen picture is reduced, contrast and anti-light ability under stronger environment light are substantially increased.
In conclusion ultra-thin anti-light projection display system provided by the invention, all component installations within the case 1, are installed
It is simple and reliable；Back projecting system occupied space reduces, i.e., the vertical range after screen requires to greatly reduce, and the scope of application is wider
It is general；Screen film layer effect keeps screen intensity higher, and does not have effect of sunlight, and contrast is high, there is better viewing effect；Screen
Using glass panel as protective layer, prevent screen from scratching, double-layer structure is sturdy and durable.
Although the present invention is disclosed as above with preferred embodiment, however, it is not to limit the invention, any this field skill
Art personnel, without departing from the spirit and scope of the present invention, when can make a little modification and perfect therefore of the invention protection model
It encloses to work as and subject to the definition of the claims.
