Detailed description of the invention
Fig. 1 is the sectional view of first embodiment of the invention display device；
Fig. 2 is the sectional view of the display device of second embodiment of the invention；
Fig. 3 is the block schematic illustration of display system of the embodiment of the present invention.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
As shown in Figure 1, Fig. 1 is the sectional view of the display device of first embodiment of the invention.The display device includes: image source
Component 1, optical prism 2.Image source component 1 includes display area and non-display area II, and optical prism 2 is set to image source component
Right above display area I is horizontal.The optical prism be right-angle prismatic rod structure, include as the plane of incidence 22, as exit facet 21,
As reflecting surface 23.
By display area I in image source component 1 and optical prism 2 as the transparent light of setting between the two of the plane of incidence 22
Glue-line is learned, with both fixed relative position.Source images caused by image source component 1 are by being incident to optics rib as the plane of incidence 22
It inside mirror 2, is projected on the picture reflecting surface 23 of optical prism 2, and as reflecting on 23 surface of reflecting surface, is projected to as going out
Face 21 is penetrated, to be observed by user.By the way that optical prism 2 is arranged on the display area I of image source component 1, to change display
The position of the imaging surface of device 100.
Further, in optical prism 2 as the surface of reflecting surface 23 is equipped with catoptric imaging coating, to improve as reflecting surface 23
Reflecting effect and image quality.By as the surface of reflecting surface 23 is coated with catoptric imaging ink, and making anti-in optical prism 2
Penetrating imaging ink solidification can be made into catoptric imaging coating.Or the reflexive high metal (such as silver) of selection is to replace catoptric imaging
Ink, and by way of plating, a reflective metal layer is set in the picture reflecting surface 23 of optical prism 2, with reflection image source component 1
Display area I shown by image.
As shown in Figure 1, optical prism 2 is right-angle prismatic rod structure, section is preferably isosceles right triangle.By institute
Crevice projection angle is 45 °, therefore projecting ratio is 1:1.I.e. optical prism 2 throws image shown by region shown by image source component 1
It is incident upon on the picture reflecting surface 23 of optical prism 2, and the image proportional projected in projection process is constant.
Projection ratio can be changed in crevice projection angle by changing optical prism 2, and if projectional angle is 60 °, projection image is horizontal
It is 1:1 to ratio, longitudinal ratio isIt can be by the angle of change projectional angle, to change the aspect ratio of source images.
As shown in Fig. 2, Fig. 2 is the sectional view of the display device of second embodiment of the invention, the cross section of optical prism 2 is
One right-angled trapezium quadrangular.Reduce the volume of optical prism 2 while meeting drop shadow effect, and then reduces display device 200
Overall volume.
In the embodiment above, it can be handled by the edge to optical prism 2, so that two neighboring face is micro- curved surface
Transition connection is carried out, the corner angle to avoid optical prism 2 are excessively sharp and damage to user.
Above-mentioned optical prism can be cavity structure in other embodiments, i.e. imaging surface is telescopic catoptric arrangement,
Its exit facet is equipped with telescope support, is stretched by expansion bracket bracket and telescopic catoptric arrangement, to change optical prism
Crevice projection angle, and change the aspect ratio of imaging.
The settable zoom lens (not shown) between image source component 1 and optical prism 2, with the display to image source component 1
Image shown by the I of region zooms in and out, to realize the effect of the image of the display large area of image source component 1 by small size.
Specially image shown by the image source component 1 of small size is projected to the picture reflection of optical prism 2 after zoom lens scale
It is emitted behind face 23 towards as exit facet 21.After zoom lens select enlarging function, the image source component 1 of small size can be realized
The technical effect of the image of large area is shown, to further decrease the entire area of display device.
Optical prism 1 is made of the material with heat-insulating properties, heat-blocking action is played to image source component 2, to avoid height
Under temperature state, cause image source component 1 impaired because temperature is excessively high.Such as in summer, irradiation image source component 1 will cause sunlight for a long time
The surface local temperature of image source component 1 is excessively high, and accelerates the aging of image source component 1.The material of the heat-insulating properties can be oxidation
Indium tin, composite ceramics nanometer tungsten oxide or other transparent materials with heat-insulating properties.
The present invention also provides a kind of display system, chief component is image source component 1, prism imaging system 3, imaging
Panntographic system 4.Image source component 1 is for generating source images.Prism imaging system 3 is for receiving and produced by reflection image source component 1
Source images.Imaging scaling system 4 is set between image source component 1 and prism imaging system 3, for being produced to image source component 1
Raw source images zoom in and out.
Prism imaging system 3 be specially a right angle triangular prism, including as the plane of incidence 22, as exit facet 21, as reflecting surface 23.
It is the right-angle surface of right-angle prismatic column as the plane of incidence 22, as exit facet 21, as the inclined-plane that reflecting surface 23 is right-angle prismatic column.By changing
The acute angle size in the section of angle triangular prism is straightened, the aspect ratio of projection source images can be changed.
Prism imaging system 3 is heat-blocking action to be played to image source component 1, made by the good material of heat insulation to keep away
Exempt to cause 1 local heating of image source component to be heated up in the direct projection of sunlight long-time, and accelerates the aging of image source component 1.
The high optics bonding of permeability can be respectively set between imaging scaling system 4 for image source component 1, prism imaging system 3
Glue, while fixed relative position, to avoid influencing to project the image quality of image due to using other adhesive glues.
It is to be illustrated to preferable implementation of the invention, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
