The photo-induced compatible stereoscopic display printed matter consists of printed images, optical elements and an excitation light source. The printed image is used for providing a 2D image and a parallax synthetic image, and the 2D image is printed by conventional ink; the parallax composite image is printed with photoluminescent paint to provide a stereoscopic image. Only the 2D image of the printed image can be seen under normal light irradiation conditions. When the excitation light source irradiates the printed image, the photoluminescent coating can be excited, so that the parallax composite image is developed. The optical element is used for projecting the visualized parallax composite image, so that a view point is formed in space, and a parallax image corresponding to each view point position can be seen. When the eyes of the viewer are respectively at different viewpoint positions, the parallax images corresponding thereto can be seen, thereby generating stereoscopic vision.
Description
Technical Field
The present invention relates to display technology, and more particularly, to stereoscopic display technology.
Background
The 3D display technology is a display technology that can realize real reproduction of stereoscopic scenes, which can respectively provide different parallax images for human eyes, thereby enabling a person to generate stereoscopic vision. Generally, a stereoscopic display print is composed of a raster and a printed stereoscopic parallax composite image. By precise coupling, the stereo parallax composite image pixels can be raster projected in a specified direction, thereby forming a viewpoint. However, conventional stereoscopic display prints can only achieve 3D display. Therefore, the invention provides a photo-compatible stereoscopic display printed matter. The printed matter can normally display 2D images under sunlight, and can display stereoscopic images through photoluminescence under the action of an excitation light source.
Disclosure of Invention
The invention provides a photo-induced compatible stereoscopic display printed matter. Fig. 1 is a schematic structural diagram of the photo-compatible stereoscopic display printed matter. The photo-induced compatible stereoscopic display printed matter consists of printed images, optical elements and an excitation light source. The printed image is used for providing a 2D image and a parallax synthetic image, and the 2D image is printed by conventional ink; the parallax composite image is printed with photoluminescent paint to provide a stereoscopic image. Only the 2D image of the printed image can be seen under normal light irradiation conditions. When the excitation light source irradiates the printed image, the photoluminescent coating can be excited, so that the parallax composite image is developed. The optical element is used for projecting the visualized parallax composite image, so that a view point is formed in space, and a parallax image corresponding to each view point position can be seen. When the eyes of the viewer are respectively at different viewpoint positions, the parallax images corresponding thereto can be seen, thereby generating stereoscopic vision.
Alternatively, the 2D image may be printed with a material other than ink, such as toner.
Alternatively, the optical element may be a lenticular lens grating, a lens array, a slit grating, or a pinhole array.
Alternatively, a plurality of excitation light sources may be provided, each exciting a corresponding different photoluminescent paint image.
Alternatively, the printing position of the 2D image may not overlap with the printing position of the parallax composite image, and the optical element may be disposed only in the region where the parallax composite image is located.
Alternatively, the excitation light source may be an ultraviolet light source and the photoluminescent coating material may be ultraviolet fluorescent ink.
Alternatively, the 2D image may be printed with a photoluminescent coating, and the parallax composite image is printed with a conventional ink, so that the stereoscopic image is displayed under normal light irradiation conditions, and the 2D image is displayed when the printed image is irradiated by the excitation light source.
In the invention, besides the normal 2D image display, the photoluminescent coating can be excited by the excitation light source, so that the printed matter displays a stereoscopic image, and the invention can display 2D and stereoscopic images simultaneously. Therefore, the present invention is particularly suitable for a case where a building plan is displayed using a 2D image and a building effect is displayed using a stereoscopic image.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
Examples
Fig. 1 is a schematic structural diagram of a photo-compatible stereoscopic display printed matter 010 according to the present embodiment. In the figure, the x-coordinate represents the horizontal direction in space, the y-coordinate represents the vertical direction in space, and z represents the direction perpendicular to the x-y plane. Referring to fig. 1, the present embodiment provides a photo-compatible stereoscopic printed matter 010, which is composed of a printed image 100, an optical element 200 and an excitation light source 300, wherein the optical element 200 is a lenticular lens grating, and the excitation light source 300 is an ultraviolet light source.
The photo-compatible stereoscopic display print 010 provided in this embodiment will be further described below.
The printed image 100 is used to provide a 2D image and a parallax composite image, the 2D image being printed in conventional ink; the parallax composite image is printed with ultraviolet fluorescent ink to provide a stereoscopic image.
Referring to fig. 2, under the normal light irradiation condition, only the 2D image of the printed image 100 can be seen, and the parallax composite image printed by the uv fluorescent ink cannot be seen. At this time, due to the condensing effect of the lenticular lens as the optical element 200, the human eye can see the 2D image on the printed image 100 in a sampled manner through each of the lenticular lenses on the lenticular lens at an arbitrary position, thereby realizing 2D image display.
Referring to fig. 3, the excitation light source 300 irradiates all areas of the printed image 100 with ultraviolet rays via the optical element 200, and excites ultraviolet fluorescent ink to form photoluminescence, thereby developing the parallax composite image. The lenticular lens as the optical element 200 may project the visualized parallax composite image so that viewpoints are formed in space, and a parallax image corresponding thereto can be seen at each viewpoint position. When the eyes of the viewer are respectively at different viewpoint positions, the parallax images corresponding thereto can be seen, thereby generating stereoscopic vision.
In the present invention, since the excitation light source 300 excites the photoluminescent coating material in addition to normally providing 2D image display, the present invention can display 2D and stereoscopic images simultaneously, thereby enabling the printed matter to display stereoscopic images. Therefore, the present invention is particularly suitable for a case where a building plan is displayed using a 2D image and a building effect is displayed using a stereoscopic image.
