Description

Technical Field

[0001] This utility model relates to the field of optical equipment, and in particular to a negative refractive glass for realizing dual-image levitation imaging on a single screen. Background Technology

[0002] Currently, there are two main methods for achieving air-levitation imaging: one is similar to a HUD (Head-Up Display), which uses optical reflection technology to project important information or data onto a transparent interface in front of the driver's or pilot's line of sight, creating a virtual image suspended in the air. HUDs require large aspherical mirrors for this purpose, resulting in high costs, a small field of view, a narrow observation range, and a poor viewing experience. The other method uses negative-refractive glass to form a real image in the air. While this method can achieve real images in air, existing negative-refractive glass has a square opening, resulting in a 90° difference in viewing angle between the two images. This significant difference in viewing angles fails to meet the requirements for shared viewing experiences, such as movies or games, in vehicles where the driver and passenger can watch together. Therefore, an optical structure that can solve these technical problems is needed. Utility Model Content

[0003] The main objective of this application is to provide a negative refractive glass for realizing dual-image levitation imaging on a single screen, aiming to solve the problems mentioned in the background art.

[0004] This application provides a negative refractive glass for realizing dual-image levitation imaging on a single screen. The negative refractive glass is disposed on one side of the image source and is tilted relative to the image source. The negative refractive glass has hexagonal holes arranged in a honeycomb pattern. Only two adjacent inner sidewalls of each hexagonal hole are affected by the projection light from the image source and are reflected, so that the projected image is reflected after passing through the hexagonal hole to form two side-by-side projected images.

[0005] Furthermore, the hexagonal hole is a regular hexagon.

[0006] Furthermore, the angle between the plane containing the negative refractive glass and the plane containing the image source is 45 degrees.

[0007] Furthermore, the negative refractive glass is tilted toward the image source so that the projected light from the image source is projected onto the two adjacent inner sidewalls at the bottom of any hexagonal hole.

[0008] This invention features densely arranged, through-hole, honeycomb-shaped hexagonal apertures on a negative refractive glass. Light emitted from an image source is projected into the honeycomb apertures of the negative refractive glass and reflected by two adjacent surfaces within the apertures, thus forming two side-by-side real images in two directions. The same pixel is also imaged in two directions within adjacent apertures. Multiple adjacent apertures image the same pixel, superimposing them to form the final image, increasing the field of view of the final image plane. This fulfills the need for both the driver and passenger to watch together, providing a better viewing angle and experience for watching movies, playing games, or for both drivers and passengers to watch together in a car.

[0016] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figure 1-4 This application provides a negative refractive glass 100 for realizing dual-image levitation imaging on a single screen. The negative refractive glass 100 is disposed on one side of the image source 200 and is inclined relative to the image source 200. The negative refractive glass 100 is provided with hexagonal holes 10 arranged in a honeycomb pattern. Only two adjacent inner sidewalls 11 of the hexagonal holes 10 are subjected to the projection light from the image source 200 and are reflected, so that the projected image is reflected after passing through the hexagonal holes 10 to form two side-by-side projected images.

[0018] This invention features a densely arranged, through-hole, honeycomb-shaped hexagonal aperture 10 on a negative refractive glass 100. Light emitted from an image source 200 is projected into the honeycomb aperture of the negative refractive glass 100 and reflected by two adjacent surfaces within the aperture, thus forming two side-by-side real images in two directions. The same pixel is also imaged in two directions within adjacent apertures. Multiple adjacent apertures image the same pixel and superimpose them to form the final image, increasing the field of view of the final image plane. This fulfills the requirement that both the driver and passenger can watch together, providing a better viewing angle and experience for watching movies, playing games, or watching together in a car.

[0019] In one embodiment of this utility model, the hexagonal hole 10 is a regular hexagon.

[0020] In one embodiment of this utility model, the angle between the plane of the negative refractive glass 100 and the plane of the image source 200 is 45 degrees.

[0021] like Figure 3-4 As shown, in one embodiment of the present invention, the negative refractive glass 100 is inclined toward the image source 200 so that the projection light of the image source 200 is projected onto the two adjacent inner sidewalls 11 at the bottom of any hexagonal hole 10, so that the generated image is located above the negative refractive glass 100.

[0022] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent scope of this application.
