Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Fig. 2 be a kind of vehicle window display system architectures block diagram provided in an embodiment of the present invention, the system include polarising glass 21,
It is arranged on the optical projection system 22 of vehicle interior；Optical projection system 22 includes projector light source 221, polarization spectroscope 222, images of left and right eyes
Display chip 223 and images of left and right eyes projection lens 224.
It should be noted that myopia or the hypermetropia crowd of wearing spectacles is needed, can will be inclined in the embodiment of the present invention
The polarized lenses of glasses 21 of shaking are fixed on its glasses, and the embodiment of the present invention does not do especially limit to the assembling morphology of polarising glass 21
It is fixed, as long as can be used in receiving the image and the extraneous reflected light of elimination on right and left eyes display chip.
Polarization spectroscope 21, for the polarization of light that sends projector light source 221 into the orthogonal polarization state of two beams
Light is radiated at respectively on images of left and right eyes display chip 223.
Images of left and right eyes display chip 223, it is mutual in two beams for being input into left-eye image and eye image to be shown respectively
It is under vertical polarization state light irradiation that left-eye image and eye image is respectively transmitted on images of left and right eyes projection lens 224.
Images of left and right eyes projection lens 224, the left-eye image and eye image for images of left and right eyes display chip 223 to be transmitted is divided
Do not project to 23 on glass for vehicle window, and reflexed to 21 in polarising glass by glass for vehicle window 23.
The polarization direction of the images of left and right eyes polarized lenses of polarising glass 21 respectively with the orthogonal polarization state light of two beams

Picture.That is the left polarized lenses of polarising glass 21 only receive the image of left eye display chip, and right polarized lenses only receive right eye and show
The image of chip, enables polarising glass 21 to eliminate the effects of the act the polarization state light of images of left and right eyes eyeglass, and eliminates glass for vehicle window 23
Outer portion strong reflection.
Wherein, natural light is circularly polarized light, and circularly polarized light has 50% when the polarized lenses of polarising glass 21 and declines
Subtract；And the optic pollution caused by reflected light is elliptically polarized light, elliptically polarized light when polarized lenses, its decay with it is inclined
The direction that shakes is relevant, because the polarization direction of two polarized lenses in the embodiment of the present invention is mutually perpendicular to, so elliptically polarized light is passed through
Its decay is complementary after two polarized lenses, i.e., the polarized light for necessarily having a polarized lenses will produce declining more than 50%
Subtract, so in the case where ambient is too strong, user also can see the virtual image of system by a certain glasses.
The polarization of light that the vehicle window display system of the embodiment of the present invention is sent projector light source using polarization spectroscope into
The orthogonal polarization state light of two beams, makes two beam polarization state light be radiated at respectively on images of left and right eyes display chip, by vehicle window
After glass-reflected, through polarising glass process after reach human eye such that it is able to realize to emergency light reflex pollution average attenuation 50%,
To external world natural optical attenuation 50% and realization are almost unattenuated through the light of right and left eyes, and do not interfere with each other.
In a preferred embodiment, the vehicle window display system also includes graphics processing unit, waits to show for generating
Show the left-eye image and eye image of (information such as instrumental panel of such as vehicle), be sent to images of left and right eyes display chip 223, it is left and right
Eye display chip 223 on left-and right-eye images through glass for vehicle window 23 reflection after, reach polarized lenses 21 in, due to corresponding to
The polarization direction of the light of left-and right-eye images is consistent with the polarization direction of the images of left and right eyes polarized lenses of polarising glass 21, therefore
Left and right eyes can be respectively received images of left and right eyes picture, by eyes aggregation feature, images of left and right eyes picture is superimposed on the retina,
The three-dimensional visual effects of 3D are produced by cerebral nerve, strengthens visual effect.
