Description

Technical Field

[0001] The invention relates to a high-performance integrated imaging 3D display system which adopts an aperture array to suppress aberration, and belongs to the technical field of display. Background Art

[0002] Three-dimensional (3D) display technology provides viewers with a stereoscopic visual experience with a sense of depth, breaking through the limitations of traditional two-dimensional flat display and is one of the main directions of the next generation of new display technology. Three-dimensional display technology includes assisted 3D display and naked-eye 3D display. Integrated imaging 3D display is a naked-eye light field 3D display technology. It is based on light field theory and records and reproduces the light information of each viewpoint, so that viewers can watch 3D images without wearing any auxiliary equipment.

[0003] The traditional integrated imaging 3D display system includes a 2D display screen and a modulation device, and usually uses a microlens array as a modulation device to complete the recording and reproduction of 3D objects or scenes. After recording the 3D object, an element image array (EIA) is obtained. After the element image array is loaded onto the 2D display screen, the 3D image is displayed through the modulation of the microlens array. However, due to the limited total amount of display information contained in the 2D display screen, there is a constraint relationship between the display performance of the integrated imaging 3D display, which is specifically manifested in low display resolution, small viewing angle, small display depth and display crosstalk.

[0004] Conventional integrated imaging 3D display systems consist of a 2D display screen and a microlens array (MLA). The display screen is loaded with an elementary image array (EIA), and the emitted light is modulated by the MLA to reconstruct a 3D image in the space before and after the central depth plane (CDP). In the resolution priority mode, a real image of the screen or a virtual image entering the screen is presented. The display screen usually uses an LCD display screen, and the total amount of information is limited. The performance parameters such as spatial resolution, field of view, and display depth are mutually restricted. If the system parameters are changed to improve a certain parameter, it may cause other parameters to decrease. The backlight module integrated in the 2D display screen is a diffuse backlight, and the light emission angle of the pixel is uncontrollable. The pixels of the elementary image on the display screen will be imaged through non-corresponding microlenses, resulting in display crosstalk. Since the optical paths of recording and reconstruction are opposite, the depth of the re-added image is opposite to the original image in the depth direction, and there will be a problem of depth inversion. If the MLA used is a closely arranged structure, the pitch between the microlenses is limited, which limits the field of view of the system and is prone to crosstalk. Therefore, the performance of conventional integrated imaging 3D display systems is limited and the display effect is poor.

[0005] In view of the above, the present invention aims to provide a high-performance integrated imaging 3D display system that uses an aperture array to suppress aberrations, so as to solve one or more of the above-mentioned technical problems. Summary of the invention

[0018] According to another aspect of the present invention, the distribution of the elementary image array loaded on the 2D display screen corresponds to the structure of the aperture array and the macro lens array, and can be arranged periodically or non-periodically.

[0062] According to another preferred embodiment of the present invention, the aperture array 802 is placed in the center of the 2D display screen 801 and the macro lens array 803 and is a curved structure, such as Figure 8 shown.

[0064] According to yet another preferred embodiment of the present invention, the working principle of the present invention is further described in detail below.

[0065] Figure 1 This is a schematic diagram of the structure of a high-performance integrated imaging 3D display system using an aperture array to suppress aberration according to a first preferred embodiment of the present invention. Figure 2 for Figure 1A top view of the structure. A conventional integrated imaging 3D display system may be composed of a 2D display screen 101, a macro lens array 103, and a holographic scattering screen 104, which can present a real image 3D display with an out-of-screen effect through the holographic scattering screen 104. A spherical single lens is usually used in a macro lens array, and the off-axis aberration is large, which affects the clarity of the 3D display at a large field of view. The 3D display result is affected by the aberration of the spherical single lens, and there will be a certain amount of image blur. Therefore, it is proposed to add a layer of aperture array 102 to the structure of the conventional integrated imaging 3D display system, see Figure 1 , Figure 2 The high-performance integrated imaging 3D display system structure using an aperture array to suppress aberrations includes a 2D display screen 101, an aperture array 102, a macro lens array 103, and a holographic scattering screen 104. The aperture array 102 is used to limit the aperture of the light beam entering each lens, thereby suppressing the aberration of lens imaging and improving the 3D display effect of integrated imaging.

[0066] Figure 3 For use in Figure 1 Schematic diagram of the structure of the macro lens array 103. The macro lens array 103 is composed of a lens substrate 301 and a lens unit 302. The middle of the lens substrate 301 is a stepped circular hole, which is convenient for placing the lens therein. The lens unit 302 adopts a spherical single lens with a small focal length and a large relative aperture, which is a discrete arrangement form, that is, there is a gap between adjacent lenses 302. p1 is the lateral dimension of the lens unit 302, p2 is the longitudinal dimension of the lens unit 302, d1 is the lateral spacing between adjacent lenses of the lens unit 302, and d2 is the longitudinal spacing between adjacent lenses of the lens unit 302. The lens spacing of the lens unit 302 is greater than the lens size, that is:

[0067] p1 <d1,p2<d2

[0068] This increases the size of the elementary image corresponding to the lens unit 302, which is beneficial to the improvement of the field of view and the number of viewpoints. The field of view of the integrated imaging system is mainly determined by the properties of the lens array. The lens characteristics of small focal length and large relative aperture can make the distance between the display screen 101 and the macro lens array 103 small enough, so that the field of view is further improved. However, there are gaps between the lens units arranged in a discrete form, which will lead to blank areas in the middle of the reconstructed 3D image, resulting in information loss. The holographic scattering screen 104 can effectively alleviate this problem.

[0069] Figure 4 For use in Figure 1Schematic diagram of the structure of the aperture array 102. The aperture array 102 is composed of an aperture substrate 401 and an aperture aperture 402. The aperture substrate 401 corresponds to the lens substrate 301 in the macro lens array 103 and has the same size. r1 is the lateral size of the aperture aperture 402, r2 is the longitudinal size of the aperture aperture 402, t1 is the lateral spacing between adjacent apertures of the aperture aperture 402, and t2 is the longitudinal spacing between adjacent apertures of the aperture aperture 402. The aperture aperture 402 corresponds to the lens unit 302 in the macro lens array 103 one by one, that is:

[0070] t1 <d1,t2<d2

[0071] And the size of the aperture 402 is smaller than the size of the lens unit 302, that is:

[0072] r1 <p1,r2<p2

[0073] Figure 5 The schematic diagram of the aperture array 102 suppressing aberration according to the first preferred embodiment of the present invention. Under normal circumstances, the pixel points of the elementary image 501 on the display screen emit light in all directions, and the emitted light rays 504 and 505 pass through the entire area of ​​a single lens 502 in the macro lens array 103. Due to the aberration of the single lens 502, the image point of the pixel is a diffuse spot. A certain aperture 503 in the aperture array 102 is added in front of the single lens 502 to control the aperture of the light beam entering the single lens 502. After the central light beam 511 passes through the aperture 503, it is imaged by the single lens 502, and the edge light beam 505 is blocked by the aperture 503. Among the light rays emitted by the pixel points of the elementary image 501 on the display screen, only the central light beam 511 can pass through the single lens 502, which helps to reduce the diffuse spot of the image point, improve the imaging quality, and suppress the aberration under the condition of large viewing angle. In addition, placing an aperture in front of the single lens 502 can also prevent the light emitted by the primitive image 501 on the display screen from entering the non-corresponding lens, which can play a role in suppressing display crosstalk.

[0074] Therefore, the aperture array 102 can control the aperture of the light beam entering each lens unit 302 in the macro lens array 103, thereby suppressing the aberration and crosstalk displayed under a large field of view, improving the clarity of the display result, and improving the optical display performance.

[0075] Figure 6The diagram is a principle diagram of directional diffusion of the holographic scattering screen 104 according to the first preferred embodiment of the present invention. The primitive image array 601 on the 2D display screen emits light, which passes through two adjacent single lenses 602 in the macro lens array 103 and converges to the plane 603 where the holographic scattering screen 104 is located. After the directional diffusion effect of the holographic scattering screen 104, each beam of light generates an expansion of angle Δφ in the horizontal and vertical directions. The light field reconstructed by the traditional integrated imaging 3D display system is discrete. Using the macro lens array 103 in a discrete arrangement form will make the reconstructed light field more discrete. The holographic scattering screen 104 scatters the light and converts the discrete light field into a quasi-continuous distribution on the basis of maintaining the original light directionality, so that the light field of the reconstructed 3D image is closer to the original light field, eliminating the information loss caused by the discrete arrangement of the lens units 302 in the macro lens array 103. At the same time, due to the scattering of light, the display system with an original field angle of θ can expand the field angle to Δφ+θ after adding the holographic scattering screen 104.

[0076] Figure 7 The figure is a top view of the structure of a high-performance integrated imaging 3D display system that uses an aperture array to suppress aberrations according to a second preferred embodiment of the present invention. The structure of the high-performance integrated imaging 3D display system that uses an aperture array to suppress aberrations includes a 2D display screen 101, a macro lens array 103, an aperture array 102, and a holographic scattering screen 104. The aperture array 102 is placed in the center of the macro lens array 103 and the holographic scattering screen 104, and is a conventional straight-surface structure. The aperture array 102 is used to limit the exit beam aperture of each lens unit 302 in the macro lens array 103, thereby suppressing the aberration of lens imaging and the crosstalk of display, and improving the 3D display effect of integrated imaging.

[0077] Figure 8 The present invention is a top view of the structure of a high-performance integrated imaging 3D display system that uses an aperture array to suppress aberrations according to the third preferred embodiment of the present invention. The structure of the high-performance integrated imaging 3D display system that uses an aperture array to suppress aberrations includes a 2D display screen 801, an aperture array 802, a macro lens array 803, and a holographic scattering screen 804.

Among them, the aperture array 802, the macro lens array 803, and the holographic scattering screen 804 are all curved structures, and the aperture array 802 is used to control the aperture of the light beam entering each lens unit in the macro lens array 803, suppress display aberrations and crosstalk, and improve the clarity of the display results. The curved surface structure can improve the field of view of the integrated imaging 3D display system and further improve the optical display performance.
