Technical Field

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

[0002] In the prior art, stereoscopic technology based on traditional parallax barriers and cylindrical lens methods can basically support a multi-user glasses-free three-dimensional experience, provided that all viewers are located at approximately the same distance from the screen, that is, the optimal viewing distance. However, for outdoor advertising, it needs to adapt to a wide range of pedestrian areas and viewers in cars; for cinemas, it needs to adapt to the audience in the entire cinema auditorium. Any solution that is successfully applied to scenes such as outdoor advertising or cinemas must clearly adapt to a wide area. Since the existing naked-eye three-dimensional display device needs to be at an optimal viewing distance to obtain a good viewing effect, the optimal viewing distance is a plane parallel to the display screen. Therefore, users need to be in this plane to watch, but for some specific scenes, such as cinemas, the audience's positions are distributed front and back, so the existing display device cannot be applied to various viewing scenes, affecting the audience's viewing experience.

[0022] The radial optics-based display device involved in the embodiment of the present invention, 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 to a horizontal plane or a position close to the horizontal plane of the light-guiding component away from the light-emitting display panel, thereby 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 audience's viewing experience.

[0023] At present, stereo technology based on traditional parallax barriers and cylindrical lens methods can basically support a multi-user glasses-free 3D experience, provided that all viewers are at approximately the same distance from the screen, that is, the optimal viewing distance. However, for application scenarios such as outdoor advertising, it is necessary to adapt to a wide range of pedestrian areas and viewers in cars, and for cinemas, the display device needs to adapt to the audience in the entire cinema auditorium. Therefore, solutions applied to scenarios such as outdoor advertising or cinemas need to clearly adapt to a wide area. Among them, cinemas were the first application scenario to envision this naked-eye 3D viewing environment, and early naked-eye 3D cinemas and 3D film photography have achieved rapid development.

[0024] Existing naked-eye 3D display devices require an optimal viewing distance to achieve a good viewing effect. The optimal viewing distance is a plane parallel to the display screen. Therefore, users need to be in this plane to watch. However, for some specific scenes, such as theaters, the audience is distributed in front and back, and existing display devices are not suitable for this scene. Figure 1 and Figure 2 As shown, in the prior art, the display screen 400 is arranged in parallel with the parallax barrier 500, and the light-transmitting portion and the opaque barrier provided on the parallax barrier 500 are imaged at the observation position 600 by selecting appropriate hardware parameters and performing image mapping on the display screen 400. Due to the size restrictions of the display screen 400 and the parallax barrier 500, the size of the observation position 600 is quite limited, and only the audience in the observation position 600 can clearly observe the three-dimensional image on the display screen 400, which greatly limits the effective observation range of the audience. With the widespread application of self-luminous flat panel displays, especially for large LED screens that can provide high-brightness images and high-saturation colors, a display technology based on radial optics is needed, so that the imaging positions are distributed on the auditorium to effectively ensure the audience's viewing experience.

[0025] Based on the above, an embodiment of the present invention provides 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 to a horizontal plane or a position close to the horizontal plane of the light-guiding component away from the side of the light-emitting display panel, thereby effectively expanding the observation distance of the display device based on radial optics in the horizontal direction, improving the compatibility and viewing convenience of the display device based on radial optics, and enhancing the audience's viewing experience.

[0026] See also Figure 3 , Figure 3 FIG. 2 shows a structural diagram of a radial optical display device provided by an embodiment of the present invention. Figure 3 and Figure 4 As shown, the radial optical display device of the embodiment of the present 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 the radial component 210 includes 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 component 200, and 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 on the intersection line 120 of the plane where the light-emitting display panel 100 is located and the plane where the light-guiding component 200 is located, and the top of the light-emitting display panel 100 and the bottom of the light-emitting display panel 100 are both parallel to the intersection line 120. In practical applications, the light-emitting display panel 100 is a device or appliance for displaying images and colors, such as an LED display screen, an LCD display screen, etc. Among them, the LED display screen is a display screen that displays text, graphics, images, videos, and signals by controlling the display mode of semiconductor light-emitting diodes. The light guide component 200 sets a series of light and dark stripes between the light-emitting display panel 100 and the audience, so that the slight parallax generated by the distance between the audience's eyes will cause the opaque stripes to block the left and right eyes, so that the pixels seen by the left eye and the right eye are different, thereby achieving a three-dimensional effect of naked eye observation of the image. The light and dark stripes on the light guide component 200 are formed by a barrier portion 211 and a light-transmitting portion 212. In the embodiment of the present application, the barrier portion 211 and the light-transmitting portion 212 are long strips and are not arranged in parallel. The extension lines of both sides of the barrier portion 211 and the light-transmitting portion 212 converge to the same point, that is, 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 guide component 200.

[0027] By setting 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 to the side of the light-guiding component 200 away from the light-emitting display panel 100, effectively expanding the viewing distance of the display device based on radial optics 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 in a horizontal plane or a position close to the horizontal plane, thereby improving the compatibility and viewing convenience of the display device based on radial optics and enhancing the audience's viewing experience.

[0028] In another embodiment, the barrier portion 211 and the light-transmitting portion 212 are arranged at intervals, and the barrier portion 211 and the light-transmitting portion 212 are aligned in a non-horizontal direction. In practical applications, the barrier portion 211 and the light-transmitting portion 212 are arranged at intervals, and light and dark stripes can be formed on the light guide assembly 200, so that the slight parallax generated by the distance between the audience's eyes will cause the opaque stripes to block the left and right eyes, so that the pixels seen by the left eye and the right eye are different, thereby achieving a three-dimensional effect of naked eye observation of the image.

[0029] In another embodiment, the extension lines of the side edges 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 long strips and are not arranged in parallel. The extension lines of both sides of the barrier portion 211 and the light-transmitting portion 212 converge at the convergence point 213, which can ensure that the imaging pattern of the light-emitting display panel 100 after passing through the light-guiding component 200 can be uniformly and clearly displayed on the side of the light-guiding component 200 away from the light-emitting display panel 100, ensuring 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, and effectively expanding the imaging distance of the display device based on radial optics in the horizontal direction.

[0030] Please refer to Figure 4 , Figure 4 FIG. 2 shows an enlarged view of the structure of the light-emitting display panel 100 and the light guide assembly 200. Figure 4 As 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 axial extension portion 214 diffused outward from the light-transmitting portion 212 covers a partial area on the light-emitting display panel 100, and in this partial area, the aperture width of the light-transmitting portion 212 is substantially constant. In the middle position of the light-emitting display panel 100, it can be seen that the vertical arrangement direction of the pixel points 110 is parallel to the light-transmitting portion 212, or nearly parallel. In this case, the color and depth of the image will be reduced. Therefore, in some embodiments, the light-emitting display panel 100 is rotated at a preset angle on the plane where it is located, and the preset angle is determined by the arrangement of the sub-pixels. By rotating the light-emitting display panel 100, the color imbalance or poor three-dimensional effect of the three-dimensional image can be effectively avoided, and the imaging stability of the display device based on radial optics can be improved. Specifically, in order to reduce image artifacts, such as color imbalance or poor three-dimensional effect, the light-emitting display panel 100 can be rotated. According to the arrangement of sub-pixels, the image mapping is matched to a preset angle, such as 45°, 90°, etc. In addition, it must be considered that some preset angles will increase the difficulty of hardware construction of the light-emitting display panel 100. In practical applications, the preset angle is often set to 90° to facilitate the installation and fixation of the light-emitting display panel 100, which also improves the viewing experience of the audience.

[0031] See also Figure 5 , Figure 5 FIG. 2 shows a structural diagram of a radial optical display device provided by an embodiment of the present invention. Figure 5As shown, the radial optical display device of the embodiment of the present invention includes a light-emitting display panel 100 and a light guide component 200; the light guide component 200 includes a plurality of radial components 210, and the radial components 210 are lenses 220, and the focus of the lenses 220 is located on the light-emitting display panel 100; the convex surfaces of the plurality of lenses 220 are cones, 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 guide 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 light guide component 200 is located away from the light-emitting display panel 100, and the top of the light-emitting display panel 100 and the bottom of the light-emitting display panel 100 are both parallel to the intersection line 120.

[0032] By providing 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 to the side of the light-guiding component 200 away from the light-emitting display panel 100, thereby effectively expanding the horizontal viewing distance of the display device based on radial optics; 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 changed quickly and accurately to adapt to different viewing environments, and the light imaging position can be located in a horizontal plane or a position close to the horizontal plane, thereby improving the compatibility and viewing convenience of the display device based on radial optics and enhancing the viewing experience of the audience.

[0033] In another embodiment, the lens 220 is a convex lens, and the convex surface of the lens 220 faces the light-emitting display board 100. Specifically, the convex lens is made according to the principle of light refraction, and the convex lens is a lens that is thicker in the center and thinner at the edge. Convex lenses are divided into double convex, plano-convex and concave-convex forms. The convex lens has the function of converging light, so it is also called a converging lens. The thicker convex lens has the functions of telescopic and converging. In the embodiment of the present application, the lens 220 adopts a plano-convex structure, the convex surface of the lens 220 faces the light-emitting display board 100, and ensures that the focus of the lens 220 is located on the light-emitting display board 100.

[0034] In another embodiment, a plurality of pixels 110 are provided on the light-emitting display panel 100, and the pixel 110 includes a plurality of sub-pixels 111 arranged vertically or horizontally. The pixel 110 is the smallest light-emitting unit on the display screen, and usually includes three sub-pixels 111 of red, green and blue. The pixel 110 and the sub-pixel 111 jointly determine the color and clarity on the screen. The pixel range of the display screen is affected by two factors: the screen size and the resolution. The larger the screen size, the more pixels 110 are usually accommodated; the higher the resolution, the denser the pixels 110 per unit area. With the continuous development of science and technology, the pixel range of the display screen is constantly expanding, bringing people a clearer and more delicate visual enjoyment. By setting the pixel 110 and the sub-pixel 111, it can be ensured that the light-emitting display panel 100 can stably and clearly emit light of different colors to the light guide component 200, and form a colorful three-dimensional image in the observation area, thereby enhancing the viewing experience of the audience.

[0035] In another embodiment, the side of the light guide component 200 away from the light emitting display panel 100 forms an observation plane 300, and the plane where the light guide component 200 is located forms an angle with the plane where the light emitting display panel 100 is located. , so that the intersection line 120 is 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 guide assembly 200 can be quickly and accurately obtained, ensuring the display effect of the display device based on radial optics.

[0036] In another embodiment, the inclination angle between the observation plane 300 and the horizontal plane is By angle The inclination angle between the observation plane 300 and the horizontal plane is determined by the positional relationship between the light-emitting display panel 100 and the light-guiding component 200. , the observation plane 300 can be flexibly set to improve the compatibility and viewing convenience of the radial optical display device.

[0037] Reference Figure 6 , Figure 6 FIG. 1 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 inclination angle between the observation plane 300 and the horizontal plane is The angle between the plane where the light-emitting display panel 100 is located and the plane where the light-guiding component 200 is located is , the height of the light-emitting 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 , and we get the following formula:

[0038] In addition, 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 , and we get the following formula:

[0039] According to the above two formulas, we get the following formula:

[0040] Based on this, the angle , the length of the top end of the radial component 210 and the length of pixel 110 is , the inclination angle between the observation plane 300 and the horizontal plane can be determined as In practical applications, the angle between the observation plane 300 and the horizontal plane can be quickly determined according to the on-site installation environment and related distance and angle parameters to ensure the positioning accuracy of the observation plane 300. At the same time, when the observation plane 300 has been determined, the angle can also be calculated by the above formula , and then quickly position and install the radial optics-based display device.

[0041] Reference Figure 7 and Figure 8 , Figure 7 FIG. 4 shows a top view of a radial optical display device according to an embodiment of the present invention. Figure 8 FIG. 4 shows a side view of a display device based on radial optics according to another embodiment of the present invention. Figure 7 As shown, a plurality of observation areas 310 are provided in the observation plane 300. When both eyes of the observer are located in the observation area 310, the observer can perceive the three-dimensional effect of the picture displayed by the light-emitting display panel 100. When both eyes of the observer are located in the observation area 310, the observer can perceive the three-dimensional effect of the picture displayed by the light-emitting display panel 100. Figure 7 and Figure 8 As shown, an audience seat 311 is provided in the observation area 310, and the audience seat 311 is located in the same observation area 310. At this time, both eyes of the observer are located in the same observation area 310, and the observer can perceive the three-dimensional effect of the picture displayed by the light-emitting display panel 100. By setting the observation plane 300 and the observation area 310, it can effectively ensure that the observer can stably and clearly perceive the three-dimensional effect of the picture displayed by the light-emitting display panel 100, thereby improving the viewing experience of the observer.

[0042] 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 the light is emitted from the virtual projection point 320, it is refracted by the light-guiding component 200 and converges on 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, it is convenient to accurately determine the effective observation point 340, thereby effectively improving the viewing effect of the observer. In traditional movie systems, light from a projector must pass through an optical component, such as a parallax barrier or a lens screen, be reflected by the screen, and then be transmitted again through the optical component and returned to the audience. At present, with the help of self-luminous display panels such as liquid crystal displays, this process is simplified, and through image mapping relationships, it is matched with the image previously received from the projector, without the need to use a front projector as an image source. Figure 3 As shown, by setting the virtual projection point 320 as a virtual projector, a light signal is continuously output to an imaginary horizontal line 340 perpendicular to the axis ZZ and passing through the virtual point. In the case of a two-viewpoint stereoscopic display, this line includes two parts, a left horizontal line 341 and a right horizontal line 342. The rays emitted from these parts pass through the aperture on the light guide assembly 200 to form left and right images on the light-emitting display panel 100. Then, the light from these areas will return through the aperture to form a left viewing area 343 and a 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 from the virtual projection point 320 from the left horizontal line 341 and the right horizontal line 342. The content on the virtual projection point 320, i.e., 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 toward the convergence point 213. Meanwhile, the left viewing area 343 and the right viewing area 344 are formed by the light emitted by the light-emitting display panel 100 through the aperture, similar to the mapping of a parallel barrier or a convex lens screen. Therefore, the above-mentioned direct mapping is not only applicable to the presentation of two views, but can also be extended to the multi-view presentation involving a series of views, and can also be used for scenes of light field display.

[0043] In another embodiment, the height of the convergence point 213 and the virtual projection point 320 is the average eye height. This structure ensures that the imaging plane of the display device based on radial optics is close to the eye position of the audience, so that the audience can clearly observe the three-dimensional effect of the picture displayed by the light-emitting display panel 100, and improve the viewing convenience of the display device based on radial optics. In this case, the convergence point 213 and the virtual projection point 320 are also located at the average eye height from the ground. This scenario assumes that the audience is observing the light-emitting display panel 100 while walking or standing. Since the inclination of the observation plane 300 increases with the distance from the light-emitting display panel 100, in other embodiments, a theater-style high and low seat can be used so that the audience's field of view will not be blocked by the audience in front.

[0044] The radial optics-based display device of the embodiment of the present application is provided with a light-emitting display panel 100 and a light-guiding component 200. The light-guiding component 200 can image the light emitted by the light-emitting display panel 100 to a horizontal plane or a position close to the horizontal plane on the side of the light-guiding component 200 away from the light-emitting display panel 100, thereby 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 providing 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, and form a colorful three-dimensional image in the observation area, thereby enhancing the viewing experience of the audience; by providing 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 picture displayed by the light-emitting display panel 100, thereby enhancing the viewing experience of the audience.

[0046] It is understandable that in order to achieve the three-dimensional effect corresponding to the displayed picture, multiple pictures need to be configured to show the effect of the pattern on the picture at different angles. In practical applications, the image information corresponding to the picture, such as RGB information, is obtained to accurately obtain the image information of the picture. Among them, RGB information is obtained by changing the three color channels of red (R), green (G), and blue (B) and superimposing them on each other to obtain a variety of colors. RGB represents the colors of the three channels of red, green, and blue. This standard includes almost all colors that can be perceived by human vision. Therefore, it is necessary to obtain the total number of pictures and their image information to accurately display the three-dimensional effect of multiple pictures.

In some embodiments, in order to facilitate the processing and transmission of pictures, the pictures are arranged in order, and the pictures are numbered from large to small or from small to large, so as to facilitate the number counting and batch processing of the pictures.

[0049] Reference Fig. 9 , Fig. 9 FIG. 1 is a structural diagram of a display device based on radial optics according to another embodiment of the present invention. Fig. 9 As shown, the number of the picture corresponding to the pixel point 110 is calculated by the total number, the total number of rows of the pixel points 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:

[0050] in, , is the length of the top end of the radial component 210, is the length of the bottom end of the radial component 210. When the radial component 210 includes the barrier portion 211 and the light-transmitting portion 212, is the sum of the lengths of the tops of the single barrier portion 211 and the light-transmitting portion 212, is the sum of the lengths of the bottom ends of the single barrier portion 211 and the light-transmitting portion 212. When the radial component 210 is a lens 220, is the width of the top of a single lens 220, is the width of the bottom end of a single lens 220 .

[0051] It should be noted that in the above formula It is the remainder operation. The remainder refers to the part that is not divided by another number. It is the result of the remainder.

[0052] Specifically, The first Ledi The number of the picture corresponding to the pixel 110 of the row, is the total number of rows of pixel points 110, is the total number of pictures, is the position offset coefficient. It is used to adjust according to the position offset between the pixel point 110 and the radial component 210. When the pixel point 110 is facing the light-transmitting portion 212, the position offset coefficient In practical applications, when there is a positional offset between the pixel point 110 and the light-transmitting portion 212, the positional offset coefficient , at this time, by adjusting the position offset coefficient To correct the size .

[0053] S3000, driving the pixel point 110 to emit light according to the number and the corresponding image information to display the three-dimensional effect of the picture.

[0054] It is understandable that when obtaining the number of the picture corresponding to the pixel point 110 After that, at this time, is [1, ] is an integer in the interval, according to Picture on Ledi The image information of the line, such as RGB information, is then controlled to Ledi The pixel points 110 of the row emit corresponding light. When the pixel points 110 on the light-emitting display panel 100 emit light according to the above steps S1000-S3000, the three-dimensional effect of the picture can be effectively displayed on the observation plane 300.
