Description

Virtual stereoscopic image projection display device

The invention relates to a virtual stereoscopic image projection display device.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a conventional virtual stereoscopic image projection display device. The conventional virtual stereoscopic image projection display device 10 includes a liquid crystal display 11 and a transparent quadrilateral cone 13 . The emitted image light source 111 is reflected by the transparent quadrilateral cone 13 and changes the direction of travel into the viewer's eye 20, and the viewer can see a suspended virtual stereoscopic image 15. Since the brightness of the image light source 111 emitted by the liquid crystal display 11 cannot be effectively improved, a brighter image cannot be seen when the viewer views it at a remote place. In addition, the size of the virtual stereoscopic image 15 is limited by the size of the liquid crystal display 11, and when it is desired to view a larger-sized virtual stereoscopic image, it is replaced with a larger-sized liquid crystal display, so that the construction cost is increased.

In view of this, the main object of the present invention is to provide a virtual stereoscopic image projection display device, which can provide a virtual stereoscopic image with high brightness and large size for viewing by a viewer at a remote location, and the size of the virtual stereoscopic image can also be adjusted.

The virtual stereoscopic image projection display device of the present invention comprises a projector, a transparent quadrangular cone screen and a reflector. The projector projects an image source. The transparent quadrilateral cone is disposed on one side of the projector, and the image light source is projected onto the transparent quadrilateral cone. The reflector is disposed on one side of the transparent quadrilateral reflector to reflect the image source of the transparent quadrilateral curtain.

The transparent quadrilateral cone screen comprises four triangular flat glass sheets, and each of the triangular flat glass sheets comprises a first surface and a second surface.

The triangular flat glass may further comprise four visible high penetration films, and each visible high penetration film is plated on the first side.

The image light source projects a special image, and the special image includes a front view image, a rear view image, a left view image, and a right view image, a front view picture, a back view picture, a left view picture, and a right view view. The picture is arranged in a cross.

The virtual stereoscopic image projection display device of the present invention may further comprise a mirror disposed on one side of the projector to change the direction of travel of the image light source projected by the projector.

The projector is a micro projector (Pico Projector).

Please also refer to Figures 2 and 3. 2 is a schematic view showing an embodiment of a virtual stereoscopic image projection display device according to the present invention, and FIG. 3 is a triangular diagram of FIG. Side view of the plate glass. The virtual stereoscopic image projection display device 30 includes a projector 31, a transparent quadrilateral cone 33, a reflector 35, and a mirror 37. The transparent quadrangular cone screen 33 includes four triangular flat glass sheets 331, 332, 333, and 334, and the transparent quadrangular cone screen 33 has a pyramid shape. If one of the triangular flat glass sheets 331 is taken out and viewed from the side, the triangular flat glass 331 includes a first surface 3311 and a second surface 3312, and a visible high transparent film 33111 is plated on the first surface 3311. The visible light high transmission film 33111 can enhance the transmittance of visible light. The configuration of the other triangular flat glass 332, 333, 334 is similar to that of the triangular flat glass 331, and therefore the description thereof will be omitted.

During operation, the projector 31 projects an image light source 311. The image light source 311 is reflected by the mirror 37 to change the traveling direction and is directed to the transparent quadrilateral cone 33, and then directly penetrates the transparent quadrilateral cone 33 to the reflecting plate 35, and is directed toward the reflecting plate. The image light source 311 of 35 will be reflected back to the transparent quadrilateral cone 33, and finally reflected by the transparent quadrilateral cone 33 to change the direction of travel, so that the image source 311 enters the viewer's eye 40, and the viewer's perception of the space due to the misalignment of the space , a virtual stereoscopic image 39 of the suspension can be seen. When the viewer stands in front of the four triangular plate glasses 331, 332, 333, 334, respectively, the front or rear view or the left or right view of the virtual stereoscopic image 39 can be seen separately.

In the above embodiment, the image light source 311 projects a special image so that the viewer can see the suspended virtual stereo image 39, and the special image projected by the image light source will be further explained below. Please also refer to Figure 4, Figure 5 and Figure 6. Figure 4 is a schematic diagram of the special image projected by the image source of Figure 2, and Figure 5 is the front view of the virtual stereo image of Figure 2, Figure 6.
