Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display panel, display device, adjustment method and related equipment. Background Technology

[0002] With the rapid development of stereoscopic display technology, there is an increasing demand for stereoscopic display devices. Among the many technologies for achieving three-dimensional stereoscopic display, naked-eye stereoscopic display is highly favored in the field of three-dimensional stereoscopic display because it eliminates the need for viewers to wear glasses. Specifically, switchable resin-type cylindrical liquid crystal lens technology has gradually become the mainstream naked-eye 3D display solution due to its excellent 3D display effect and ability to quickly switch between 2D and 3D.

[0003] However, in related technologies, for each lens, some light rays may fail to converge at the focal point. If the light rays do not converge at the focal point, the 3D effect will be degraded, crosstalk will increase, and product yield will be affected.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] In view of this, the present disclosure provides a display panel, display device, adjustment method and related equipment to solve or partially solve the above problems.

[0006] In view of the above objectives, in a first aspect, this disclosure provides a display panel, comprising:

[0007] Substrate;

[0008] A light-emitting layer is disposed on one side of the substrate and configured to emit light toward a side away from the substrate, forming an optical path;

[0010] The first substrate further includes:

[0011] The convex lens layer is divided into at least one sub-lens layer along a first direction, and the at least one sub-lens layer is provided with different radii of curvature; wherein, the first direction is the direction from the light-emitting layer to the optical path adjustment layer.

[0012] Based on the same concept, in a second aspect, this disclosure also provides a display device, including: a display panel as described in the first aspect.

[0013] Based on the same concept, in a third aspect, this disclosure also provides a method for adjusting a display panel using the method described in the first aspect, comprising:

[0014] The light-emitting layer is controlled to emit light in a direction away from the substrate, thus forming an optical path;

[0015] When the light path passes through the light path adjustment layer, it is refracted and adjusted by lenses with at least two radii of curvature contained in the light path adjustment layer, so that the light path converges to a point after passing through the light path adjustment layer.

[0016] Based on the same concept, in a fourth aspect, this disclosure also provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the method described in the first aspect above.

[0018] Based on the same concept, in a sixth aspect, this disclosure also provides a computer program product, including computer program instructions that, when executed on a computer, cause the computer to perform the method described in the first aspect above.

[0019] As can be seen from the above description, this disclosure provides a display panel, a display device, an adjustment method, and related equipment. The display panel includes: a substrate; a light-emitting layer disposed on one side of the substrate and configured to emit light to a side away from the substrate, forming a light path; a light path adjustment layer disposed on the side of the light-emitting layer away from the substrate, including a first substrate close to the light-emitting layer and a second substrate away from the light-emitting layer, configured to adjust the light path through lenses of at least two radii of curvature disposed on the first substrate and / or the second substrate, so that the light path converges to a point after passing through the light path adjustment layer; the first substrate further includes: a convex lens layer divided into at least one sub-lens layer along a first direction, the at least one sub-lens layer having different radii of curvature; wherein, the first direction is the direction from the light-emitting layer to the light path adjustment layer.

[0033] To make the objectives, technical solutions, and advantages of this specification clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0034] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element, object, or method step preceding the term covers the element, object, or method step listed after the term and its equivalents, but does not exclude other elements, objects, or method steps. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] As described in the background section, the main method for achieving naked-eye stereoscopic display technology in related technologies is to set a grating in front of or behind the display panel, dividing the pixel units of the display panel into odd-numbered columns of pixels and even-numbered columns of pixels in the horizontal direction. This provides two different images for the viewer's left and right eyes respectively. The parallax effect between the left and right eye images is used to create depth of field, thereby producing a stereoscopic display effect. Gratings include two types: obstruction type and beam-splitting type. Obstruction type gratings are further divided into black-and-white parallax barrier gratings and liquid crystal slit gratings, while beam-splitting type gratings are divided into lenticular physical lenses and switchable liquid crystal lenses, etc. Among them, switchable liquid crystal lenses can be divided into three types: switchable resin-type lenticular liquid crystal lenses, switchable polarized liquid crystal lenses, and switchable electrode-type liquid crystal lenses.

[0036] Figure 1 The diagram shows the optical design and implementation principle of the naked-eye 3D product. The pitch of a cylindrical grating corresponds to multiple sub-pixels. The light emitted by the sub-pixels is refracted by the cylindrical grating and enters the left and right eyes of the person respectively. Then, the brain integrates the light and perceives the stereoscopic effect.

[0037] Subsequently, in related fields, switchable resin-type lenticular liquid crystal lens technology has gradually become the mainstream glasses-free 3D display solution due to its excellent 3D display effect and ability to quickly switch between 2D and 3D. Furthermore, it is now used in products of all sizes, including mobile phones, tablets, laptops, and televisions, achieving full-size coverage.

[0038] However, in related technologies, the lenses used in switchable resin-type cylindrical liquid crystal lens technology are generally spherical lens structures, which have only one radius of curvature. Because spherical lenses have significant spherical aberration (spherical aberration is caused by the difference in the ability of the central and edge regions of an electromagnetic lens to converge electromagnetic waves; spherical aberration is the most significant factor limiting the resolving power of a lens), such as... Figure 2 As shown, light rays located at both ends of the edge of a lens cannot converge at the focal point due to spherical aberration, forming stray rays. According to the principle of naked-eye 3D display, light rays emitted from each viewpoint first converge at the focal point through the lens structure, and then split to the left and right. The light rays from the left viewpoint are guided to the left eye, and the light rays from the right viewpoint are guided to the right eye. Then, the brain fuses them to form a 3D effect. If the light rays do not converge at the focal point, the 3D effect will be deteriorated. According to the naked-eye 3D viewpoint diagram, viewpoints 1 and 6 cannot be accurately incident on the left or right eye, thus increasing crosstalk and reducing product yield.

[0039] In light of the above-mentioned practical situation, this disclosure provides a display panel. This disclosure improves the optical path adjustment layer by adding lenses with different radii of curvature or designing a single lens to include multiple radii of curvature. This method adjusts the optical path, specifically optimizing the light path emitted from the light-emitting layers at both ends of each lens. This allows the light paths emitted from other areas to converge at a single point after passing through the optical path adjustment layer, thereby improving display performance, reducing crosstalk caused by the inability to converge the light paths, and increasing product yield.

[0040] Figure 3 A schematic diagram of the structure of a display panel provided in an embodiment of this disclosure is shown.

[0041] like Figure 3 As shown, the display panel in this embodiment specifically includes: a substrate 1100; a light-emitting layer 1200 disposed on one side of the substrate 1100 and configured to emit light to the side away from the substrate 1100, forming a light path 1201; and a light path adjustment layer 1300 disposed on the side of the light-emitting layer 1200 away from the substrate 1100, including a first substrate 1310 near the light-emitting layer 1200 and a second substrate 1320 away from the light-emitting layer 1200, configured to... Lenses with at least two curvature radii disposed on the first substrate 1310 and / or the second substrate 1320 adjust the optical path 1201 so that the optical path 1201 converges to a point after passing through the optical path adjustment layer 1300; the first substrate 1310 further includes: a convex lens layer 1311, which is divided into at least one sub-lens layer along a first direction X, and the at least one sub-lens layer is provided with different curvature radii; wherein, the first direction X is the direction from which the light-emitting layer 1200 points to the optical path adjustment layer 1300.

[0042] In this embodiment, the light-emitting layer 1200 disposed on the substrate 1100 can be composed of multiple arrayed light-emitting pixels. The light-emitting layer 1200 can emit light according to corresponding instructions to form a light path 1201. At this time, the image formed by the light-emitting layer 1200 may be a 2D basic image. After the light path 1201 is formed, it will be adjusted by the light path adjustment layer 1300 to form left and right eye images, and finally the viewer's brain receives the left and right eye images to form a 3D stereoscopic image. In this embodiment, in order to achieve the purpose of preventing crosstalk, the light path adjustment layer 1300 can set various lenses with different radii of curvature to adjust the light in the light path 1201. For example, a convex lens and a concave lens can be set with different radii of curvature, or a convex lens can have parts with different radii of curvature, or a concave lens can have parts with different radii of curvature, or a combination of the above methods, etc. In this way, light is repeatedly refracted by lenses with different radii of curvature at multiple levels, thereby improving the refraction effect of the light path 1201 and ultimately enhancing the converging ability of the light path 1201 to the focal point. This improves the display effect of the display panel, reduces crosstalk problems caused by the inability of the light path to converge, and improves product yield.

[0043] In some embodiments, such as Figure 3 As shown, the optical path adjustment layer 1300 can be further divided into a first substrate 1310 and a second substrate 1320. The two substrates can be arranged in parallel, with the first substrate 1310 closer to the light-emitting layer 1200 and the second substrate 1320 located away from the light-emitting layer 1200. Different types of lenses can then be disposed on these two substrates. Combining the optical path 1201 and the adjustment effect of different lenses on the optical path, a convex lens can be disposed on the first substrate 1310 with its convex surface away from the light-emitting layer 1200, and a concave lens can be disposed on the second substrate 1320 with its concave surface close to the light-emitting layer 1200. Of course, in some embodiments, the lens placement method can also be adjusted according to the adjustment effect of different lenses on the optical path. For example, a convex lens can be disposed on the second substrate 1320 with its convex surface away from the light-emitting layer 1200. However, considering factors such as molding difficulty, it is preferable to place the convex lens on the first substrate 1310 and the concave lens on the second substrate 1320. The lens configuration can be combined with the aforementioned embodiments. For example, only one type of lens can be configured, but this lens has multiple radii of curvature. Alternatively, multiple lenses can be configured, with different lenses having different radii of curvature, and so on.

[0044] In some embodiments, combined with Figure 3 and Figure 4As shown, a lens can include various embodiments with different radii of curvature. Taking a convex lens as an example, it can be seen from the previous embodiments that it is more effective to place the convex lens layer 1311 on the first substrate 1310. Thus, in some embodiments, only the convex lens layer 1311 can be provided, while the second substrate 1320 is a planar structure and does not refract light. Of course, in other embodiments, the second substrate 1320 can also be provided with a concave lens, etc., which will not be elaborated here.

[0045] It should be noted that, regardless of whether a convex lens is provided on the first substrate 1310 or a concave lens is provided on the second substrate 1320 (concave lenses are generally provided in correspondence with convex lenses), combined with Figure 1 As can be seen, it is generally arranged in an array of multiple convex or concave lenses. In this embodiment and the following embodiments, the part corresponding to one of the convex or concave lenses will be used as an example for illustration.

[0046] In this embodiment, taking a convex lens in the convex lens layer 1311 as an example, if the optical path adjustment layer 1300 contains only this one lens layer, the convex lens layer 1311 can be layered along the first direction X. Here, the first direction X can be the direction from the light-emitting layer 1200 to the optical path adjustment layer 1300. Figure 4 Taking the example shown, the convex lenses in the convex lens layer 1311 can be divided into layers proportionally or according to a set rule. The radius of curvature of each layer is R1, R2, R3, R4, R5, R6...Rn, and the size of these radii of curvature gradually decreases with increasing distance from the light-emitting layer 1200, i.e., R1>R2>R3>R4>R5>R6>Rn, that is, the radius of curvature gradually decreases from the sides of the lens structure towards the middle. In this way, the light emitted from the naked-eye 3D viewpoint map can be concentrated at the focal point after exiting through the aspherical lens, forming a good 3D effect and reducing crosstalk. That is, in some embodiments, the first substrate 1310 includes: a convex lens layer 1311, divided into at least one sub-lens layer along a first direction X, wherein the at least one sub-lens layer is provided with different radii of curvature; wherein, the first direction X is the direction from the light-emitting layer 1200 to the optical path adjustment layer 1300. In some embodiments, when the convex lens layer 1311 includes at least two sub-lens layers, the radii of curvature of the at least two sub-lens layers decrease sequentially along the first direction X.

[0047] Furthermore, if the convex lens in the convex lens layer 1311 has only one radius of curvature, i.e., the convex lens is a spherical lens, then a lens can be added in the optical path adjustment layer to reduce crosstalk. Figure 3As shown, a layer of concave lens layer 1321 can be provided in the second substrate 1320. Each concave lens in the concave lens layer 1321 is correspondingly arranged with the convex lens in the convex lens layer 1311, and their curvature radii are different. In this way, the adjustment of the optical path 1201 is achieved. In specific applications, in the related art, a plano-convex lens is fabricated on a glass substrate on one side, and the other side is flat. The solution of this embodiment forms a positive spherical aberration through the spherical structure of the convex lens and a negative spherical aberration through the spherical structure of the concave lens. The curvature radius of the convex lens is Rx, and the curvature radius of the concave lens is Ry, such that Rx≠Ry, thereby providing a refraction basis. Of course, in some embodiments, if the convex lens itself has multiple curvature radii, the concave lens layer 1321 can also be provided, as long as the curvature radius of the concave lens layer 1321 is different from all the curvature radii of the convex lens layer. That is, in some embodiments, the second substrate 1320 includes: a concave lens layer 1321, correspondingly arranged with the convex lens layer 1311, and configured to have a different curvature radius from the convex lens layer 1311.

[0048] In some embodiments, for the optical path adjustment layer 1300, it further includes a liquid crystal layer 1330. When the liquid crystal is non-conductive, it is in a "lying flat" state, that is, arranged in a direction perpendicular to the first direction X. The incident polarized light direction is parallel to the long axis direction of the liquid crystal molecules, corresponding to the refractive index ne. At this time, the light does not deflect, and it is in a 2D display state; in the powered-on state, the liquid crystal molecules are in an "upright" state, that is, arranged in a direction parallel to the first direction X, corresponding to the refractive index no, and no < ne. At this time, the light converges, and it is in a 3D display state. Further, for the materials of the convex lens layer 1311 and the concave lens layer 1321, their corresponding refractive indices can be n1 and n2, and it can be made that n1 = n2 = ne, that is, the refractive index of the convex lens layer 1311 is equal to the refractive index of the concave lens layer 1321 and equal to the refractive index of the liquid crystal molecules when not powered on.

[0049] In some embodiments, for the lens structure in the optical path adjustment layer 1300, corresponding protective layers can be provided. For example, a first protective layer 1312 is provided on the side of the convex lens layer 1311 close to the light-emitting layer 1200, and a second protective layer 1322 is provided on the side of the concave lens layer 1321 away from the first substrate 1310, so as to protect the structure in the optical path adjustment layer 1300. In specific applications, the first protective layer 1312 and the second protective layer 1322 can be glass substrate structures. That is, in some embodiments, the first substrate 1310 includes: a first protective layer 1312, provided on the side of the convex lens layer 1311 close to the light-emitting layer 1200. In some embodiments, the second substrate 1320 includes: a second protective layer 1322, provided on the side of the concave lens layer 1321 away from the first substrate 1310.

[0050] As can be seen from the above embodiments, the present disclosure provides a display panel, the display panel comprising: a substrate; a light-emitting layer disposed on one side of the substrate and configured to emit light to a side away from the substrate, forming a light path; and a light path adjustment layer disposed on the side of the light-emitting layer away from the substrate and configured to adjust the light path using lenses with at least two radii of curvature, so that the light path converges to a point after passing through the light path adjustment layer. The present disclosure improves the light path adjustment layer by adding lenses with different radii of curvature or designing a single lens to include multiple radii of curvature. This method of adjusting the light path allows for targeted optimization of the light path emitted from the light-emitting layers at both ends of each lens, enabling it to converge to a point with light paths emitted from other areas after passing through the light path adjustment layer. This improves the display effect, reduces crosstalk caused by the inability of the light paths to converge, and increases product yield.

[0051] Based on the same concept, this disclosure also provides a display device, including a display panel as described in any of the foregoing embodiments.

[0052] The display device described above is used to apply the corresponding display panel in the foregoing embodiments and has the beneficial effects of the corresponding display panel embodiments, which will not be repeated here.

[0053] It is understandable that the display device is a product with image display function, and it is generally driven by multiple driving circuits. For example, it can be: monitor, AR / VR device, 3D glasses, television, billboard, digital photo frame, laser printer with display function, telephone, mobile phone, personal digital assistant (PDA), digital camera, portable camcorder, viewfinder, navigator, vehicle, large wall area, home appliance, information query device (such as business query equipment of e-government, bank, hospital, power and other departments, monitor, etc.).

[0054] Based on the same concept, this disclosure also provides an adjustment method for a display panel using any of the above embodiments, such as Figure 5 As shown, the adjustment method specifically includes:

[0055] Step 502: Control the light-emitting layer to emit light in a direction away from the substrate to form an optical path.

[0056] Step 504: When the light path passes through the light path adjustment layer, the lenses containing at least two radii of curvature of the light path adjustment layer are used for refraction adjustment so that the light path converges to a point after passing through the light path adjustment layer.

[0057] In some embodiments, combined with Figure 2 and Figure 3As shown, the main source of crosstalk in the optical path is the optical path located at both ends of the lens or the image. Therefore, if the aforementioned structural adjustments cannot meet the user's requirements, further adjustments can be made to the light emission of these two ends to reduce crosstalk. Firstly, in this embodiment, for the light-emitting layer 1200, the viewpoints can be divided according to the size of each convex lens in the convex lens layer 1311. Firstly, one convex lens corresponds to one area on the light-emitting layer 1200, namely the light-emitting area. Then, the number of viewpoints to be divided can be preset, and then the division is performed evenly according to the size of the convex lens, and then mapped onto the light-emitting area to form individual viewpoints, such as... Figure 3 As shown, the luminescent area of ​​the luminescent layer 1200 can be divided into 12 viewpoints, which are numbered from 1 to 12. Of course, the above division of 12 viewpoints is only an example. Depending on the specific application scenario, the number of viewpoints can be adjusted, for example, it can be divided into 24 viewpoints, 48 ​​viewpoints, etc.

[0058] Then, since these viewpoints are generally arranged in sequence, it is possible to identify the edge viewpoints located at the edges of these viewpoints. Figure 3 In viewpoints 1 and 12, as described in the aforementioned embodiments, the crosstalk caused by the light rays from these two viewpoints is the greatest. If it is necessary to reduce crosstalk or to reduce its impact on the 3D effect, the brightness of the corresponding viewpoint can be directly reduced. Although the light path remains unchanged, the reduced brightness will also reduce the impact of the corresponding light path, thereby reducing crosstalk.

[0059] Next, the crosstalk requirement can be determined. This crosstalk requirement is the user's desired reduction in crosstalk. Based on this requirement, the final reduction in brightness at the edge viewpoint can be determined. For example, based on the crosstalk requirement, the reduction can be between 0% and 80%. For instance, assuming that the display's maximum brightness increases crosstalk by 1%, then a 50% reduction in brightness will only increase crosstalk by 0.5%. In some embodiments, the optical path adjustment layer 1300 includes a first substrate 1310 and a convex lens layer 1311 within the first substrate 1310. Controlling the light-emitting layer to emit light in a direction away from the substrate includes: determining the light-emitting area corresponding to any convex lens in the convex lens layer within the light-emitting layer; dividing the light-emitting area into viewpoints to form a plurality of sequentially arranged viewpoints; determining the crosstalk requirement and the edge viewpoints among the plurality of viewpoints; and reducing the brightness of the edge viewpoints according to the crosstalk requirement.

[0060] Furthermore, for 3D displays, it is generally necessary to form left-eye and right-eye images. Similarly, each convex lens in the convex lens layer will form two corresponding images. Therefore, among the multiple viewpoints corresponding to a single convex lens, some will correspond to the left-eye image and some to the right-eye image. These viewpoints can be divided into left-viewpoint regions and right-viewpoint regions. Viewpoints in the left-viewpoint region are used to form the left-eye image, and viewpoints in the right-viewpoint region are used to form the right-eye image. In specific scenarios, the left-viewpoint and right-viewpoint regions are generally symmetrical; that is, the viewpoint is divided into two equal parts: the left part is the left-viewpoint region, and the right part is the right-viewpoint region. For example... Figure 6 As shown, viewpoints 1 to 6 constitute the left viewpoint region, and viewpoints 7 to 12 constitute the right viewpoint region. Following this, in conjunction with the aforementioned embodiment, when adjusting the brightness of edge viewpoints, the left viewpoint region forming the left-eye image and the right viewpoint region forming the right-eye image can be further determined first. Then, the viewpoints located at the edges of these two regions are determined separately, and these viewpoints are ultimately used as edge viewpoints. For viewpoints 6 and 7, since these two viewpoints are located at the view boundary, they are also factors that add crosstalk and affect the 3D effect. Figure 6 As shown, viewpoints 1, 6, 7, and 12 are designated as edge viewpoints, where viewpoints 1 and 6 correspond to the left viewpoint region, and viewpoints 7 and 12 correspond to the right viewpoint region. In some embodiments, determining the edge viewpoints among the plurality of viewpoints includes: determining the left and right viewpoint regions within the luminescent region, and determining the viewpoints located at the two ends of the sequential arrangement within the left and right viewpoint regions, respectively, as the edge viewpoints.

[0061] In some embodiments, adjusting the brightness of an edge viewpoint can be achieved by directly adjusting the overall brightness of the edge viewpoint, or by first determining the color composition of the edge viewpoint and then adjusting the brightness of different colors based on the color composition. For example, a viewpoint may correspond to many pixels, and each pixel may be composed of sub-pixels of RGB colors. During image display, different pixels will generate light of different colors, resulting in different color proportions within a viewpoint. Therefore, the brightness of various colors can be adjusted separately based on their different color compositions. For instance, for the same crosstalk reduction requirement, for areas with more red light, since red light is inherently brighter, the brightness reduction may be greater, while for areas with more blue light, since blue light is inherently dimmer and softer, the brightness reduction may be less. That is, in some embodiments, reducing the brightness of the edge viewpoint according to the crosstalk requirement includes: adjusting the overall brightness of the edge viewpoint; or determining the color composition of the edge viewpoint and adjusting the brightness of different colors separately based on the color composition.

[0062] Furthermore, for a viewpoint, the light emitted will generally contain multiple colors. For example, if a viewpoint contains 1000 pixels and the emitted light is predominantly blue, then it may actually have 500 pixels predominantly blue, 300 pixels predominantly red, and 200 pixels predominantly green, or each pixel may emit light in the above proportions. Therefore, when adjusting the brightness of this viewpoint, the adjustment can primarily focus on blue light. For example, different light sources can be adjusted to different degrees according to the above proportions: blue light reduced by 50%, red light by 30%, and green light by 20%. The brightness reduction ratio can range from 0% to 70%. That is, during image display, for each frame, the brightness adjustment range for different colors can be determined according to their proportions within the viewpoint. The specific adjustment range can be adjusted according to the aforementioned proportions, or the adjustment range for different colors can be determined based on specific settings. That is, in some embodiments, adjusting the brightness of different colors according to the color composition includes: determining the brightness adjustment range of the different colors according to the proportion of the different colors in the edge viewpoint.

[0063] In some embodiments, to further enhance the effect of reducing crosstalk and prevent edge differences caused by brightness reduction, the brightness of adjacent viewpoints to the edge viewpoint can also be reduced. The brightness adjustment method can be based on the degree of brightness reduction of the edge viewpoint; for example, a gradual reduction can be adopted, i.e., the magnitude of brightness reduction gradually decreases. Alternatively, a corresponding degree of brightness reduction can be set, for example, setting the brightness reduction of adjacent viewpoints to 25%. It should be noted that the adjacent viewpoints determined in this embodiment can be a single adjacent viewpoint or multiple adjacent viewpoints. Taking the determination of a single adjacent viewpoint as an example... Figure 6 In the illustrated embodiment, in addition to reducing the brightness of viewpoints 1, 6, 7, and 12, the adjacent viewpoints 2, 5, 8, and 11 can also have their brightness reduced by a percentage ranging from 0% to 50%. That is, in some embodiments, after reducing the brightness of the edge viewpoints according to the crosstalk requirement, the method further includes: determining at least one adjacent viewpoint according to the arrangement order, and adjusting the brightness of the at least one adjacent viewpoint according to the degree of brightness reduction of the edge viewpoints.

[0064] The methods described in the above embodiments are applied to the corresponding display panels in the foregoing embodiments. The specific contents of each step and the corresponding beneficial effects have been described in the foregoing embodiments of the display panels, so they will not be repeated in this embodiment.

[0065] It should be noted that the method of this disclosure embodiment can be executed by a single device, such as a computer or server. The method of this disclosure embodiment can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method of this disclosure embodiment, and the multiple devices will interact with each other to complete the method described.

[0066] It should be noted that the above description describes specific embodiments of this disclosure. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in a different order than that shown in the above embodiments and still achieve the desired results. Furthermore, the processes depicted in the drawings do not necessarily require the specific or sequential order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0067] Finally, combining the aforementioned display panel and adjustment methods, a simulation was performed using Matlab software, based on a 16-inch display screen with a resolution of [resolution missing]. The pixel width is 89.76µm, and the optimal viewing distance is set to 550mm. Scheme 1 involves adjusting only the convex lens layer (i.e., setting multiple radii of curvature on the convex lens); Scheme 2 involves a combination of convex and concave lenses (i.e., both the convex and concave lenses are spherical, but with different curvatures); and Scheme 3 involves adjusting the brightness of the edge viewpoint. This results in the simulation results shown in Figures 7(a) to 7(e), where Figure 7(a) is the simulation result for the control group without any adjustments, Figure 7(b) is the simulation result for Scheme 1 only, Figure 7(c) is the simulation result for Scheme 2 only, Figure 7(d) is the simulation result for Scheme 1 plus Scheme 3, and Figure 7(e) is the simulation result for Scheme 2 plus Scheme 3. The resulting 3D degrees of freedom with zero crosstalk are 40.7%, 50.4%, 50.9%, 54.8%, and 55.9%, respectively, showing a gradual improvement. Zero crosstalk 3D degrees of freedom refers to the percentage of the total width when crosstalk is 0 in a monocular view, as shown in Figure 7(a). Theoretically, the greater the 3D degrees of freedom, the smaller the 3D crosstalk. In the simulated graph, the horizontal axis represents the viewing angle, and the vertical axis represents the view brightness. The red line represents the left-eye view brightness, and the blue line represents the right-eye view brightness.
