Description

Technical Field

[0001] This invention relates to the field of three-dimensional display technology, and in particular to a display device and display method based on radial optics. Background Technology

[0002] In existing technologies, stereoscopic techniques based on traditional parallax barriers and lenticular lens methods can generally support multi-user glasses-free 3D experiences, provided that all viewers are positioned at approximately the same distance from the screen, i.e., the optimal viewing distance. However, for outdoor advertising, it needs to adapt to a wide range of pedestrian areas and viewers inside cars; for cinemas, it needs to adapt to viewers throughout the entire auditorium. Any solution successfully applied to scenarios such as outdoor advertising or cinemas must clearly adapt to a wide area. Since existing glasses-free 3D display devices require an optimal viewing distance to achieve a good viewing effect, this optimal viewing distance is a plane parallel to the display screen. Therefore, users need to be within this plane to view the image. However, in certain scenarios, such as cinemas, the audience's positions are distributed back-to-back, making existing display devices unsuitable for various viewing scenarios and impacting the viewer's experience. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a display device and display method based on radial optics, which sets the imaging plane at a position on or near the horizontal plane, thereby expanding the viewing distance in the horizontal direction, improving the compatibility and viewing convenience of the radial optics-based display device, and enhancing the viewing experience for the audience.

[0004] The technical solution adopted by this invention to solve its problem is:

[0005] In a first aspect, embodiments of this application provide a display device based on radial optics, including a light-emitting display panel and a light-guiding assembly; the light-guiding assembly includes a plurality of radial components, each radial component including a barrier portion and a light-transmitting portion; the convergence point of the barrier portion and the light-transmitting portion is located below the light-emitting display panel; the light-emitting display panel is located in front of the light-guiding assembly, and the horizontal distance between the light-emitting display panel and the light-guiding assembly gradually decreases from top to bottom; the convergence point is on the intersection line of the plane where the light-emitting display panel is located and the plane where the light-guiding assembly is located, and the top and bottom of the light-emitting display panel are both parallel to the intersection line.

[0006] The aforementioned radial optics-based display device has at least the following beneficial effects: by setting up a light-emitting display panel and a light-guiding component, the radial component can image the light emitted by the light-emitting display panel onto a horizontal plane or a position close to the horizontal plane on the side of the light-guiding component away from the light-emitting display panel, effectively expanding the viewing distance of the radial optics-based display device in the horizontal direction, improving the compatibility and viewing convenience of the radial optics-based display device, and enhancing the viewing experience of the audience.

[0007] Furthermore, the barrier portion and the light-transmitting portion are spaced apart, and they are aligned in a non-horizontal direction. This structure ensures that the radial components can converge the light emitted by the light-emitting display panel onto a horizontal or near-horizontal plane, more clearly displaying the three-dimensional effect of the image to the viewer and enhancing the viewing experience.

[0008] Furthermore, the extended lines of the sides of the barrier portion and the light-transmitting portion converge at the convergence point. This structure ensures that the three-dimensional effect of the image displayed on the light-emitting display panel can be observed from positions at different distances from the light-guiding component, expanding the imaging distance of radial optics-based display devices in the horizontal direction and improving the compatibility of radial optics-based display devices.

[0009] Secondly, embodiments of this application also provide a display device based on radial optics, including a light-emitting display panel and a light-guiding assembly; the light-guiding assembly includes multiple radial components, and each radial component is a lens, the focal point of which is located on the light-emitting display panel; the convex surfaces of the multiple lenses are cones, and the apex of the cones containing the multiple lenses is a convergence point located below the light-emitting display panel; the light-emitting display panel is located in front of the light-guiding assembly, and the horizontal distance between the light-emitting display panel and the light-guiding assembly gradually decreases from top to bottom; the convergence point is on the intersection line of the plane where the light-emitting display panel is located and the plane where the light-guiding assembly is located, and the top and bottom of the light-emitting display panel are both parallel to the intersection line.

[0010] The aforementioned radial optics-based display device has at least the following beneficial effects: by setting up a light-emitting display panel and a light-guiding component, the lens can image the light emitted by the light-emitting display panel onto a horizontal plane or near a horizontal plane on the side of the light-guiding component away from the light-emitting display panel, effectively expanding the viewing distance of the radial optics-based display device in the horizontal direction, improving the compatibility and viewing convenience of the radial optics-based display device, and enhancing the viewing experience of the audience.

[0011] Furthermore, the lens is a convex lens, with its convex surface facing the light-emitting display panel. This structure ensures that the lens can stably and orderly converge the light emitted from the light-emitting display panel onto the side of the light-guiding component away from the light-emitting display panel, improving the viewing convenience of the radial optics-based display device.

[0012] Furthermore, the light-emitting display panel is provided with multiple pixels, including multiple sub-pixels arranged vertically or horizontally. By setting the pixels and sub-pixels, it can be ensured that the light-emitting display panel can stably and clearly emit light of different colors to the light guiding component, and form a colorful three-dimensional image in the observation area, thereby enhancing the viewer's viewing experience.

[0013] Furthermore, the side of the light-guiding component away from the light-emitting display panel forms an observation plane, and the plane containing the light-guiding component forms an angle with the plane containing the light-emitting display panel, such that the intersection line lies on the observation plane. By forming an observation plane, the imaging area of ​​the light-emitting display panel after passing through the light-guiding component can be obtained quickly and accurately, ensuring the display effect of the radial optics-based display device.

[0014] Furthermore, the tilt angle between the observation plane and the horizontal plane is determined by the included angle, the length of the top end of the radial component, and the length of the pixel. Determining the angle between the observation plane and the horizontal plane by the positional relationship between the light-emitting display panel and the light-guiding component allows for flexible setting of the observation plane, improving the compatibility and viewing convenience of radial optics display devices.

[0015] Furthermore, the tilt angle The calculation formula is as follows:

[0016] ;

[0017] in, The included angle is... The length of the pixel. The length of the top end of the radial component.

[0018] The beneficial effects of the aforementioned radial optics-based display device are as follows: By setting up a light-emitting display panel and a light-guiding component, the light-guiding component can image the light emitted by the light-emitting display panel onto a horizontal plane or near a horizontal plane on the side of the light-guiding component away from the light-emitting display panel, effectively expanding the imaging distance of the radial optics-based display device in the horizontal direction, improving the compatibility and viewing convenience of the radial optics-based display device, and enhancing the viewing experience of the audience; by determining the angle between the observation plane and the horizontal plane through the positional relationship between the light-emitting display panel and the light-guiding component, the observation plane can be flexibly set, improving the compatibility and viewing convenience of the radial optics-based display device; by setting the observation plane and observation area, it can be effectively ensured that the observer can stably and clearly perceive the three-dimensional effect of the image displayed on the light-emitting display panel, enhancing the viewing experience of the audience; by setting pixels and sub-pixels, it can be ensured that the light-emitting display panel can stably and clearly emit light of different colors to the light-guiding component, forming a colored three-dimensional image in the observation area, enhancing the viewing experience of the audience.

[0019] Thirdly, embodiments of this application also provide a display method based on radial optics, applied to the radial optics-based display device described above. The radial optics-based display device includes a light-emitting display panel and a light-guiding component. The light-emitting display panel is provided with a plurality of pixels. The method includes:

[0020] Get the total number of images and their image information;

[0021] The image number corresponding to each pixel is obtained based on the total number of images, the total number of rows of pixels, the length of the top end of the radial component, and the length of the bottom end of the radial component.

[0022] The pixels are driven to emit light according to the number and the corresponding image information to display the three-dimensional effect of the image.

[0023] The beneficial effects of the above-mentioned radial optics-based display method are as follows: by obtaining the image number corresponding to each pixel based on the total number of images, the total number of rows of pixels, the length of the top end of the radial component, and the length of the bottom end of the radial component, the corresponding image information of each pixel can be accurately obtained, ensuring that the light-emitting display panel can stably and clearly emit light to the light-guiding component and form a clear three-dimensional image, effectively expanding the viewing distance of the radial optics-based display device in the horizontal direction and improving the viewing experience of the audience.

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0038] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0039] The radial optics-based display device of the present invention, by setting a light-emitting display panel and a light-guiding component, enables the light emitted by the light-emitting display panel to be imaged onto a horizontal plane or near a horizontal plane on the side of the light-guiding component away from the light-emitting display panel. This effectively expands the imaging distance of the radial optics-based display device in the horizontal direction, improves the compatibility and viewing convenience of the radial optics-based display device, and enhances the viewing experience of the audience.

[0040] Currently, stereoscopic technologies based on traditional parallax barriers and lenticular lens methods can generally support multi-user glasses-free 3D experiences, provided that all viewers are at approximately the same distance from the screen, i.e., the optimal viewing distance. However, for applications such as outdoor advertising, it is necessary to adapt to a wide range of pedestrian areas and viewers inside cars. For cinemas, the display device needs to adapt to the entire audience. Therefore, solutions applied to outdoor advertising or cinemas need to clearly adapt to a wide area. Among these, cinemas were the earliest application scenario envisioned for such a glasses-free 3D viewing environment, and early glasses-free 3D cinemas and 3D cinematography saw rapid development.

[0041] Existing glasses-free 3D display devices require an optimal viewing distance to achieve a good viewing experience; this optimal viewing distance is a plane parallel to the display screen. Therefore, users need to be within this plane to view the image. However, for certain scenarios, such as cinemas, where the audience is positioned front-to-back, existing display devices are not suitable. Figure 1 and Figure 2 As shown, in the prior art, the display screen 400 and the parallax barrier 500 are arranged parallel to each other. The parallax barrier 500 has a light-transmitting part and an opaque barrier. By selecting appropriate hardware parameters and performing image mapping on the display screen 400, an image is formed at the viewing position 600. Due to the size limitations of the display screen 400 and the parallax barrier 500, the size of the viewing position 600 is quite limited, and only viewers within the viewing position 600 can clearly observe the three-dimensional image on the display screen 400, which greatly limits the effective viewing range of the viewers. With the widespread application of self-emissive flat panel displays, especially for large LED screens that can provide high-brightness images and high-saturation colors, there is a need for a display technology based on radial optics, so that the imaging position is distributed in the audience area, effectively ensuring the viewing experience of the viewers.

[0042] Based on the above, embodiments of the present invention provide a display device based on radial optics. By setting a light-emitting display panel and a light-guiding component, the light-guiding component can image the light emitted by the light-emitting display panel onto a horizontal plane or a position close to the horizontal plane on the side of the light-guiding component away from the light-emitting display panel. This effectively expands the viewing distance of the radial optics-based display device in the horizontal direction, improves the compatibility and viewing convenience of the radial optics-based display device, and enhances the viewing experience of the audience.

[0043] Please see Figure 3 , Figure 3 A structural diagram of a radial optics-based display device provided in an embodiment of the present invention is shown. Figure 3 and Figure 4 As shown, the radial optics-based display device of this invention includes a light-emitting display panel 100 and a light-guiding assembly 200. The light-guiding assembly 200 includes a plurality of radial components 210, each radial component 210 including a barrier portion 211 and a light-transmitting portion 212. The convergence point 213 of the barrier portion 211 and the light-transmitting portion 212 is located below the light-emitting display panel 100. The light-emitting display panel 100 is located in front of the light-guiding assembly 200, and the horizontal distance between the light-emitting display panel 100 and the light-guiding assembly 200 gradually decreases from top to bottom. The convergence point 213 is on the intersection line 120 of the plane where the light-emitting display panel 100 is located and the plane where the light-guiding assembly 200 is located. The top and bottom of the light-emitting display panel 100 are both parallel to the intersection line 120.

[0044] In practical applications, the light-emitting display panel 100 is a device or electrical appliance used to display images and colors, such as an LED display screen or an LCD display screen. An LED display screen is a display screen that displays text, graphics, images, video, and signals by controlling semiconductor light-emitting diodes. The light-guiding component 200 sets a series of alternating bright and dark stripes between the light-emitting display panel 100 and the viewer. The slight parallax caused by the distance between the viewer's eyes causes the opaque stripes to block the left and right eyes, resulting in different pixels seen by the left and right eyes, thus achieving a three-dimensional effect for naked-eye image viewing. The alternating bright and dark stripes on the light-guiding component 200 are formed by a barrier portion 211 and a light-transmitting portion 212. In this embodiment, the barrier portion 211 and the light-transmitting portion 212 are elongated and not parallel. The extension lines of both sides of the barrier portion 211 and the light-transmitting portion 212 converge at the same point, namely the convergence point 213 located below the light-emitting display panel 100, to ensure the imaging effect of the light-emitting display panel 100 after passing through the light-guiding component 200.

[0045] By setting up the light-emitting display panel 100 and the light-guiding component 200, the radial component 210 can image the light emitted by the light-emitting display panel 100 onto the side of the light-guiding component 200 away from the light-emitting display panel 100, effectively expanding the viewing distance of the radial optics-based display device in the horizontal direction. By adjusting the angle between the plane where the light-guiding component 200 is located and the plane where the light-emitting display panel 100 is located, the light imaging position of the light-emitting display panel 100 can be quickly and accurately changed to adapt to different viewing environments, and the light imaging position can be located on or near the horizontal plane, improving the compatibility and viewing convenience of the radial optics-based display device and enhancing the viewing experience of the audience.

[0046] In another embodiment, the barrier portion 211 and the light-transmitting portion 212 are spaced apart and aligned along a non-horizontal direction. In practical applications, the spaced-apart barrier portion 211 and the light-transmitting portion 212 can form alternating light and dark stripes on the light-guiding component 200. This causes a slight parallax in the distance between the viewer's eyes, resulting in opaque stripes blocking the left and right eyes, making the pixels seen by the left and right eyes different, thereby achieving a three-dimensional effect for viewing images without the naked eye.

[0047] In another embodiment, the extension lines of the sides of the barrier portion 211 and the light-transmitting portion 212 converge at the convergence point 213. As can be seen from the above, the barrier portion 211 and the light-transmitting portion 212 are elongated and not parallel. The extension lines of both sides of the barrier portion 211 and the light-transmitting portion 212 converge at the convergence point 213. This ensures that the imaging pattern of the light-emitting display panel 100 after passing through the light-guiding component 200 can be displayed uniformly and clearly on the side of the light-guiding component 200 away from the light-emitting display panel 100. This ensures that the three-dimensional effect of the image of the light-emitting display panel 100 can be observed at positions at different distances from the light-guiding component 200, effectively expanding the imaging distance of the radial optics-based display device in the horizontal direction.

[0048] Please refer to Figure 4 , Figure 4 An enlarged structural view of the light-emitting display panel 100 and the light-guiding assembly 200 is shown. Figure 4As shown, the radial component 210 includes a barrier portion 211 and a light-transmitting portion 212. Since the light-transmitting portion 212 converges to a convergence point 213, the axially extending portion 214, which diffuses outward from the light-transmitting portion 212, covers a portion of the light-emitting display panel 100, where the aperture width of the light-transmitting portion 212 is substantially constant. At the center of the light-emitting display panel 100, the vertical alignment of the pixel points 110 is parallel to or nearly parallel to the light-transmitting portion 212. In this case, it can lead to a reduction in color and depth in the image. Therefore, in some embodiments, the light-emitting display panel 100 is rotated by a preset angle on its plane, the preset angle being determined by the arrangement of the sub-pixels. By rotating the light-emitting display panel 100, color imbalance or poor three-dimensional effect in the three-dimensional image can be effectively avoided, improving the imaging stability of the radial optics-based display device. Specifically, to mitigate image artifacts, such as color imbalance or poor three-dimensional effect, the light-emitting display panel 100 can be rotated. Based on the arrangement of subpixels, the image is mapped and matched to a preset angle, such as 45° or 90°. Furthermore, it must be considered that some preset angles would increase the difficulty of hardware installation for the luminous display panel 100. In practical applications, the preset angle is often set to 90° to facilitate the installation and fixation of the luminous display panel 100, and also to improve the viewing experience for the audience.

[0049] Please see Figure 5 , Figure 5 A structural diagram of a radial optics-based display device provided in an embodiment of the present invention is shown. Figure 5 As shown, the radial optics-based display device of this invention includes a light-emitting display panel 100 and a light-guiding component 200. The light-guiding component 200 includes a plurality of radial components 210, and each radial component 210 is a lens 220, with the focal point of the lens 220 located on the light-emitting display panel 100. The convex surfaces of the plurality of lenses 220 are cone-shaped, and the apex of the cone 221 where the plurality of lenses 220 are located is a convergence point 213 located below the light-emitting display panel 100. The horizontal distance between the light-emitting display panel 100 and the light-guiding component 200 gradually decreases from top to bottom. The convergence point 213 is located on the intersection line 120 of the plane where the light-emitting display panel 100 is located and the plane where the side of the light-guiding component 200 away from the light-emitting display panel 100 is located. The top and bottom of the light-emitting display panel 100 are both parallel to the intersection line 120.

[0050] By setting up the light-emitting display panel 100 and the light-guiding component 200, the lens 220 can image the light emitted by the light-emitting display panel 100 onto the side of the light-guiding component 200 away from the light-emitting display panel 100, effectively expanding the viewing distance of the radial optics-based display device in the horizontal direction. By adjusting the angle between the plane where the light-guiding component 200 is located and the plane where the light-emitting display panel 100 is located, the light imaging position of the light-emitting display panel 100 can be quickly and accurately changed to adapt to different viewing environments, and the light imaging position can be located on or near the horizontal plane, improving the compatibility and viewing convenience of the radial optics-based display device and enhancing the viewing experience of the audience.

[0051] In another embodiment, lens 220 is a convex lens, with its convex surface facing the light-emitting display panel 100. Specifically, a convex lens is made based on the principle of light refraction; it is a lens that is thicker in the center and thinner at the edges. Convex lenses are classified into biconvex, plano-convex, and concave-convex types. Convex lenses have the function of converging light rays and are therefore also called converging lenses. Thicker convex lenses can provide both telescopic and converging light. In this embodiment, lens 220 adopts a plano-convex structure, with its convex surface facing the light-emitting display panel 100, ensuring that the focal point of lens 220 is located on the light-emitting display panel 100.

[0052] In another embodiment, the light-emitting display panel 100 is provided with a plurality of pixels 110, each pixel 110 including a plurality of vertically or horizontally arranged sub-pixels 111. A pixel 110 is the smallest light-emitting unit on the display screen, typically including three sub-pixels 111: red, green, and blue. Pixels 110 and sub-pixels 111 together determine the color and clarity on the screen. The pixel range of the display screen is affected by two main factors: screen size and resolution. The larger the screen size, the more pixels 110 it can accommodate; the higher the resolution, the denser the pixels 110 per unit area. With the continuous development of technology, the pixel range of the display screen is constantly expanding, bringing people a clearer and more delicate visual experience. By setting pixels 110 and sub-pixels 111, it can be ensured that the light-emitting display panel 100 can stably and clearly emit light of different colors to the light guiding component 200, forming a colored three-dimensional image in the observation area, thus enhancing the viewer's viewing experience.

[0053] In another embodiment, the side of the light guiding component 200 away from the light-emitting display panel 100 forms an observation plane 300, and the plane where the light guiding component 200 is located forms an angle with the plane where the light-emitting display panel 100 is located. This ensures that the intersecting line 120 lies on the observation plane 300. By forming the observation plane 300, the imaging area of ​​the light-emitting display panel 100 after passing through the light guiding component 200 can be obtained quickly and accurately, ensuring the display effect of the radial optics-based display device.

[0054] In another embodiment, observe the tilt angle between plane 300 and the horizontal plane. From the included angle The length of the top of the radial component 210 and the length of the pixel 110 are determined. The tilt angle of the observation plane 300 relative to the horizontal plane is determined by the positional relationship between the light-emitting display panel 100 and the light-guiding component 200. It allows for flexible setting of the observation plane 300, improving the compatibility and viewing convenience of radial optics display devices.

[0055] Reference Figure 6 , Figure 6 This is a side view of a display device based on radial optics according to an embodiment of the present invention. Figure 6 As shown, the angle of inclination between the observation plane 300 and the horizontal plane is... The angle between the plane of the light-emitting display panel 100 and the plane of the light-guiding component 200 is . The height of the luminous display panel 100 is The distance between the top of the light-emitting display panel 100 and the top of the light-guiding component 200 is The following formula is obtained:

[0056]

[0057] Furthermore, the length of the top end of the radial component 210 is The length of pixel 110 is The distance from the top of the observation plane 300 to the top of the light-emitting display panel 100 is... The following formula is obtained:

[0058]

[0059] Based on the two formulas above, we obtain the following formula:

[0060]

[0061] Based on this, through the included angle Length of the top end of radial component 210 The length of pixel 110 is The angle of inclination between the observation plane 30° and the horizontal plane can be determined as follows: In practical applications, the angle between the observation plane 300 and the horizontal plane can be quickly determined based on the installation environment and relevant distance and angle parameters, ensuring the positioning accuracy of the observation plane 300. Furthermore, given that the observation plane 300 is already determined, the angle can also be calculated using the above formula. This allows for the rapid positioning and installation of radial optics-based display devices.

[0062] Reference Figure 7 and Figure 8 , Figure 7 The diagram shows a top view of a display device based on radial optics according to an embodiment of the present invention. Figure 8 A side view of a display device based on radial optics, according to another embodiment of the present invention, is shown. Figure 7 As shown, the observation plane 300 has multiple observation areas 310. When both eyes of the observer are within the observation area 310, they can perceive the three-dimensional effect of the image displayed on the light-emitting display panel 100. For example... Figure 7 and Figure 8 As shown, an audience seating area 311 is provided within the observation area 310, and all audience seats 311 are located within the same observation area 310. In this case, both eyes of the observer are located within the same observation area 310, allowing them to perceive the three-dimensional effect of the image displayed on the light-emitting display panel 100. By setting the observation plane 300 and the observation area 310, it is effectively ensured that the observer can stably and clearly perceive the three-dimensional effect of the image displayed on the light-emitting display panel 100, thus enhancing the viewing experience.

[0063] In another embodiment, a virtual projection point 320 corresponding to the light-emitting display panel 100 is provided on the side of the light-guiding component 200 away from the light-emitting display panel 100. When light is emitted from the virtual projection point 320, it is refracted by the light-guiding component 200 and converges onto the light-emitting display panel 100; the effective observation point 340 is between the convergence point 213 and the virtual projection point 320. By setting the virtual projection point 320, the effective observation point 340 can be accurately determined, effectively improving the viewing experience for the observer. In traditional film systems, light from the projector must pass through an optical component, such as a parallax barrier or lens screen, be reflected by the screen, and then be transmitted again through the optical component to return to the audience. Currently, with the help of self-emissive display panels such as liquid crystal displays, this process is simplified. Through image mapping, it is matched with the image previously received from the projector, eliminating the need for a front projector as the image source. Figure 3As shown, by setting the virtual projection point 320 as a virtual projector, light signals are continuously output to a fictitious horizontal line 340 that is perpendicular to the ZZ axis and passes through the virtual point. In the case of dual-viewpoint stereoscopic display, this line comprises two parts, a left horizontal line 341 and a right horizontal line 342. Rays emitted from these parts pass through an aperture on the light guiding assembly 200 and form left and right images on the light-emitting display panel 100. Then, the light from these areas returns through the aperture, forming the left viewing area 343 and the right viewing area 344, respectively. At this time, the aperture and the light-emitting display panel 100 act as reflectors. It is worth noting that when considering the virtual projection point 320 as a virtual projector, since the light-emitting display panel 100 actively emits light, the rays emitted from the first light-emitting area 130 and the second light-emitting area 140 on the light-emitting display panel 100 will produce the same left viewing area 343 and right viewing area 344 as the rays emitted by the virtual projection point 320 from the left horizontal line 341 and the right horizontal line 342. The content on virtual projection point 320, namely the images of the left horizontal line 341 and the right horizontal line 342, is transmitted to the left viewing area 343 and the right viewing area 344 extending towards the convergence point 213. Meanwhile, the left viewing area 343 and the right viewing area 344 are simply mappings formed by light emitted from the light-emitting display panel 100 through an aperture, similar to a parallel barrier or a convex lens screen. Therefore, the aforementioned direct mapping is not only applicable to the presentation of two views, but can also be extended to the presentation of multiple views involving a series of views, and can also be used in light field display scenarios.

[0064] In another embodiment, the height of the convergence point 213 and the virtual projection point 320 is at average eye level. This structure ensures that the imaging plane of the radial optics-based display device is close to the viewer's eye level, facilitating a clear observation of the three-dimensional effect of the image displayed on the light-emitting display panel 100 and improving the viewing convenience of the radial optics-based display device. In this case, the convergence point 213 and the virtual projection point 320 are also located at average eye level above the ground, assuming the viewer is observing the light-emitting display panel 100 while walking or standing. Since the tilt of the viewing plane 300 increases with the distance from the light-emitting display panel 100, in other embodiments, theater-style seating with varying heights can be used, ensuring that the viewer's field of vision is not obstructed by viewers in front.

[0065] The radial optics-based display device of this application embodiment, by setting up a light-emitting display panel 100 and a light-guiding component 200, enables the light emitted by the light-emitting display panel 100 to be imaged onto a horizontal plane or near a horizontal plane on the side of the light-guiding component 200 away from the light-emitting display panel 100. This effectively expands the imaging distance of the radial optics-based display device in the horizontal direction, improves the compatibility and viewing convenience of the radial optics-based display device, and enhances the viewing experience of the audience. By setting up pixel points 110 and sub-pixels 111, it can be ensured that the light-emitting display panel 100 can stably and clearly emit light of different colors to the light-guiding component 200, forming a colored three-dimensional image in the observation area, thus enhancing the viewing experience of the audience. By setting up an observation plane 300 and an observation area 310, it can be effectively ensured that the observer can stably and clearly perceive the three-dimensional effect of the image displayed by the light-emitting display panel 100, thus enhancing the viewing experience of the audience.

[0066] Please see Figure 10 , Figure 10 A flowchart of a radial optics-based display method provided by an embodiment of the present invention is shown. Figure 10 As shown, the radial optics-based display method of this application includes the following steps:

[0067] S1000: Obtain the total number of images and their image information.

[0068] Understandably, to achieve the desired 3D effect from an image, multiple images are needed to display the pattern's appearance from different angles. In practical applications, this is achieved by acquiring the image information, such as RGB information, to accurately capture the image's details. RGB information is obtained by varying the red (R), green (G), and blue (B) color channels and their interactions to create a wide variety of colors. RGB represents the colors of these three channels, encompassing almost all colors perceptible to human vision. Therefore, it's necessary to obtain the total number of images and their image information to accurately display the 3D effect of multiple images.

[0069] S2000: Based on the total number, the total number of rows of pixels 110, the length of the top end of the radial component 210, and the length of the bottom end of the radial component 210, the image number corresponding to pixel 110 is obtained.

[0070] Understandably, by determining the image number corresponding to each pixel based on the total number of images, the total number of rows of pixels, the length of the top end of the radial component, and the length of the bottom end of the radial component, the corresponding image information of each pixel can be accurately obtained. This ensures that the light-emitting display panel can stably and clearly emit light to the light-guiding component, forming a clear three-dimensional image and enhancing the viewer's viewing experience. In some embodiments, to facilitate image processing and transmission, the images are arranged in order, with image numbers ranging from large to small or small to large, to facilitate image quantity counting and batch processing.

[0071] Reference Figure 9 , Figure 9 This is a structural diagram of a display device based on radial optics, according to another embodiment of the present invention. Figure 9 As shown, the image number corresponding to pixel 110 is calculated using the total number, the total number of rows of pixels 110, the length of the top end of the radial component 210, and the length of the bottom end of the radial component 210, as shown in the following formula:

[0072]

[0073] in, , The length of the top end of the radial component 210, The length of the bottom end of the radial assembly 210. When the radial assembly 210 includes a barrier portion 211 and a light-transmitting portion 212, The sum of the lengths of the top ends of the individual barrier portion 211 and the light-transmitting portion 212. The sum of the lengths of the bottom ends of the individual barrier portion 211 and the light-transmitting portion 212. When the radial assembly 210 is a lens 220, The width of the top of a single lens 220. The width of the bottom of a single lens 220.

[0074] It should be noted that in the above formula... This refers to the remainder operation. The remainder is the part of a number that is not divisible by another number.

[0075] Specifically, For the first light-emitting display panel 100 Liede The image number corresponding to pixel 110 in the row. The total number of rows for pixel 110. The total number of images. This is the position offset coefficient. The position offset coefficient is used to adjust the position based on the positional offset between pixel 110 and radial component 210. When pixel 110 is directly aligned with light-transmitting portion 212, the position offset coefficient is... In practical applications, when there is a positional offset between pixel 110 and the light-transmitting part 212, the positional offset coefficient... At this point, by adjusting the position offset coefficient Size to correct .

[0076] S3000 drives pixel 110 to emit light according to the number and corresponding image information to display the three-dimensional effect of the image.

[0077] It is understandable that the image number corresponding to pixel 110 is obtained. Afterwards, at this time, For [1, An integer within the interval, according to the... The first picture Liede Image information, such as RGB information, is used to control the first row of light-emitting display panels 100. Liede Each pixel 110 in the row emits corresponding light. When the pixels 110 on the light-emitting display panel 100 emit light according to the above steps S1000-S3000, the three-dimensional effect of the image can be effectively displayed on the viewing plane 300.
