Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to a Chinese patent application filed with the China Patent Office on December 13, 2022, with application number 202211601713.4 and titled "Display Device," the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to the field of display technology, and more particularly to display devices. [Background technology]

[0003] With the continuous development of display technology, three-dimensional (3D) display technology has attracted increasing attention. 3D display technology can create a three-dimensional and realistic display. The principle is that a person's left and right eyes receive left-eye and right-eye images with a certain parallax, respectively. After the two parallax images are received by the left and right eyes, the brain superimposes and fuses the image information to create a 3D visual display effect. To achieve compatibility between ultra-multi-view 3D display and light field display, conventional subpixels are structured as pixel islands, each containing multiple subpixels. When multiple subpixels display different information and a single eye views multiple perspectives, conventional light field display can be achieved. When multiple subpixels display different information and a single eye views a single perspective, ultra-multi-view light field 3D display can be achieved.

[0038] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of them. In addition, if there is no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Based on the described embodiments of the present invention, all other embodiments that can be obtained by ordinary skilled in the art without requiring creative work fall within the protection scope of the present invention.

[0039] Unless otherwise defined, technical or scientific terms used herein have the ordinary meanings understood by those of ordinary skill in the art to which the present invention pertains. As used herein, terms such as "first," "second," and similar terms do not denote order, quantity, or importance, but are used to distinguish between different components. Terms such as "comprise" or "include" and similar terms mean that the element or object appearing before the term encompasses the elements or objects listed after the term and their equivalents, and do not exclude other elements or objects. Terms such as "connect" or "couple" and similar terms are not limited to physical or mechanical connections, but may include direct or indirect electrical connections.

[0040] The size and shape of each figure in the drawings do not reflect actual proportions, but are intended to schematically explain the contents of the present invention. In addition, the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions.

[0041] An embodiment of the present invention provides a display device, as shown in Figure 1. The display device includes a display panel 01 and a spectroscopic component 02.

[0042] The display panel 01 includes a plurality of pixel repeat units 04 arranged in an array along a row direction X and a column direction Y. Each pixel repeat unit 04 includes a plurality of pixel islands S arranged consecutively in the column direction Y. Each pixel island S includes a plurality of sub-pixels 08 arranged at intervals in the row direction X. The plurality of pixel repeat units 04 includes a plurality of pixel repeat unit rows 013 arranged in the column direction Y.

[0043] The dispersing component 02 is located on the display side of the display panel 01. The dispersing component 02 extends along a column direction Y and includes a plurality of dispersing repeat units 03 arranged consecutively in a row direction X. The dispersing repeat units 03 extend along the column direction Y and include M dispersing structures A arranged consecutively in the row direction X. Each dispersing repeat unit 03 corresponds to N columns of sub-pixels in a pixel repeat unit row. Both M and N are integers greater than 1. The dispersing structures A have focusing center lines 016 extending along the column direction Y, and the distance between the focusing center lines 016 of two adjacent dispersing structures A is a first distance l1.

[0044] Here, the sub-pixels 08 in at least some of two adjacent pixel repeat unit rows 013 are arranged with a shift in the row direction X. And / or, among the plurality of first distances l1 corresponding to the M light-splitting structures A, at least some of the first distances l1 are not equal.

[0045] Note that, when the subpixels in two adjacent pixel repeat unit rows are arranged with a shift in the row direction, this means that the centers of the subpixels in the two adjacent pixel repeat unit rows are not on the same line in the column direction.

[0046] In the related art, when a single pixel repeat unit row constitutes a repeat unit of an array of pixel repeat unit rows, i.e., when the centers of subpixels in two adjacent pixel repeat unit rows are on the same line in the column direction, a "dark zone" may be present in space in the output light beam dispersed by the M dispersing structures above the N columns of subpixels. Even when the first distances corresponding to all dispersing structures included in the dispersing component are all equal, i.e., when a single dispersing structure constitutes a repeat unit of the array of dispersing structures, a "dark zone" may be present in space in the output light beam dispersed by the M dispersing structures above the N columns of subpixels.

[0047] In a display device provided by an embodiment of the present invention, at least some subpixels in two adjacent pixel repeat unit rows are staggered in the row direction and / or at least some first distances are unequal. This prevents a single pixel repeat unit row from constituting a repeat unit of the pixel repeat unit row array and / or prevents a single dispersing structure from constituting a repeat unit of the dispersing structure array. The staggered subpixels or dispersing structures can block "dark zones" that occur in space when the emitted light beams of N columns of subpixels are dispersed by the M dispersing structures above them, compared to when the subpixels or dispersing structures are not staggered. This prevents the human eye from seeing "dark zones" as the human eye moves through the visible space and reduces the problem of macroscopic moiré fringes.

[0048] Note that, "each spectral repeat unit corresponds to the subpixels of the Nth column in the pixel repeat unit row" means that the orthogonal projection of each spectral repeat unit on the display panel plane overlaps with the orthogonal projection of the subpixels of the Nth column in the pixel repeat unit row. Because the subpixels in any two adjacent pixel repeat unit rows are shifted in the row direction, for example, in some pixel repeat unit rows, the orthogonal projection of the spectral repeat unit on the display panel plane completely covers the orthogonal projection of the subpixels of the Nth column in these pixel repeat unit rows. In the remaining pixel repeat unit rows, the orthogonal projection of the spectral repeat unit on the display panel plane does not completely cover the orthogonal projection of the subpixels of the Nth column in these pixel repeat unit rows. For subpixels located at the edge of the spectral repeat unit, the orthogonal projection of the spectral repeat unit on the display panel plane only covers a portion of the orthogonal projection of these subpixels on the display panel plane.

[0049] The display device provided by the embodiment of the present invention is applicable to three-dimensional (3D) display and can also switch between 3D and 2D display. A pixel island functions as a subpixel in 2D display, and a single pixel island contains multiple subpixels, so the same resolution as 2D display can be maintained even in 3D display mode. When combined with an eye-tracking system, it can realize a wide-view multi-view display and even a high-pixel-density (ppi) 3D display, which provides a large amount of information and reduces color crosstalk between adjacent viewpoints.

[0050] In a specific implementation, the light-splitting structure controls the light output angle of each subpixel to achieve directional light emission. In some embodiments, the light-splitting structure is a pillar lens. The pillar lens is, for example, composed of a first resin layer having a convex portion and a planarizing resin layer located on the side of the first resin layer away from the display panel. Alternatively, the function of the pillar lens can be achieved by other configurations. In some embodiments, the light-splitting structure is one of a geometric lens, a diffractive lens, a liquid crystal lens, and a liquid lens.

[0051] In addition, when the dispersing structures are pillar lenses, regardless of the configuration of the pillar lenses, the pillar lenses extend along the column direction, and the focal points of the pillar lenses are orthogonally projected onto the plane where the display panel is located, and the focusing center line is included in the orthogonal projection onto the plane where the display panel is located. When multiple dispersing structures have the same width in the row direction, the focusing center line becomes the symmetrical axis of the dispersing structures extending along the column direction.

[0052] In a specific implementation, the display panel is a liquid crystal display panel (LCD), an organic light emitting diode (OLED) display panel, a quantum dot light emitting diode (QLED), a micro inorganic light emitting diode (micro LED) display panel, or a mini light emitting diode (mini LED) display panel.

[0053] In some embodiments, as shown in FIG. 1, one pixel repeating unit 04 in the column direction Y includes three pixel islands S arranged consecutively.

[0054] Within one pixel repeating unit 04, the sub-pixels 08 of the same pixel island S have the same display color, and the sub-pixels 08 of different pixel islands S have different display colors.

[0055] 1, one pixel repeating unit 04 includes a first pixel island 05, a second pixel island 06, and a third pixel island 07. The first pixel island 05 includes multiple red subpixels R, the second pixel island 06 includes multiple green subpixels G, and the third pixel island 07 includes multiple blue subpixels B.

[0056] In some embodiments, as shown in FIG. 1, the display color of each sub-pixel 08 in a row of pixel islands S is the same.

[0057] 1, the spectroscopic repeating unit 03 is divided into an average of M subregions 031, where the subregions 031 correspond one-to-one to the spectroscopic structures A, and the subregions 031 have a first axis of symmetry 017 extending along the column direction Y. In the row direction X, the width of the spectroscopic repeating unit 03 is equal to the width of the N columns of subpixels 08 in the pixel repeating unit row 013.

[0058] 1, the splitting of the spectral repeating unit 03 into M sub-regions 031 on average means that in the row direction X, the width H3 of each sub-region 031 is all equal, the distance H4 between adjacent first symmetry axes 017 is all equal, and the width H3 of each sub-region 031 is equal to the distance H4 between adjacent first symmetry axes 017. The width of the spectral repeating unit 03 is M×H3.

[0059] In some embodiments, each pixel island includes n subpixels spaced apart in the row direction, where n is an integer greater than 1. The subpixels include subpixel aperture areas. In the row direction, the ratio of the total width of the n subpixel aperture areas to the width of the pixel island is greater than or equal to 0.9 / M and less than or equal to 1.

[0060] In some embodiments, in the row direction, the ratio of the width of the subpixel aperture region to the width of the pixel island is i / M, where i is an integer greater than or equal to 1 and less than or equal to M-1.

[0061] In some embodiments, after the light emitting regions of the N columns of sub-pixels in a pixel repeat unit row are split by the M splitting structures, the output light beam forms a continuous light emitting region in space.

[0062] In the display device provided by the embodiment of the present invention, M dispersive structures are arranged corresponding to N columns of subpixels, and the light-emitting regions of each of the N columns of subpixels are offset in space. Because the dimensions of the dispersive structures in the row direction are small, the human eye cannot specifically identify which dispersive structure a light beam comes from for the N columns of subpixels corresponding to the M dispersive structures. Therefore, to the human eye, the light beam emitted from each of the N columns of subpixels dispersed by the M dispersive structures above it appears to form a continuous light-emitting region in space, and the human eye does not see any "dark zones" when moving through the visible space.

[0063] In some embodiments, the subpixel includes a subpixel aperture region, and the ratio of the total width of the n subpixel aperture regions to the width of the pixel island in the row direction is 0.9 / M or more and 1 or less. That is, the aperture ratio of the subpixels in the pixel island is 0.9 / M or more and 1 or less.

[0064] In some embodiments, in the row direction, the light-emitting areas of the N columns of sub-pixels in a pixel repeating unit row are patched in a complementary manner in space.

[0065] In some embodiments, when i=1, that is, in the row direction, the ratio of the width of the subpixel aperture region to the width of the pixel island is 1 / M. That is, the aperture ratio of the subpixels in the pixel island is 1 / M. By setting it in this way, the subpixels below each dispersing repeat unit are arranged with a complementary offset relative to the position of the corresponding dispersing structure, and the light-emitting regions of the subpixels in N columns are patched complementary in space. That is, the optical paths of each viewpoint are closely spaced, which reduces macroscopic moiré fringes and improves the display effect.

[0066] Of course, in the row direction, the light emitting regions of the sub-pixels in the N columns in a pixel repeating unit row may overlap in space.

[0067] In some embodiments, when i is greater than 1 and less than or equal to M-1, in the row direction, the emissive areas of the N columns of sub-pixels in a pixel repeating unit row overlap uniformly in space.

[0068] In some embodiments, in the dispersing repeat unit, a ratio Vj of a vector H2-j, which is a displacement of the focusing center line of the j-th dispersing structure in the row direction with respect to the first symmetry axis, to a width h1 of the subpixel in the row direction, is expressed as follows:

number

[0069] In the display device provided by the embodiment of the present invention, the Vj corresponding to the M dispersive structures in the dispersive repeat unit are unequal, i.e., the vectors of the focusing center lines shifted in the row direction relative to the first symmetry axis are unequal. As a result, a single dispersive structure does not constitute a repeat unit of an array of multiple dispersive structures. Therefore, when a single dispersive structure constitutes a repeat unit of an array of multiple dispersive structures, it is possible to avoid the occurrence of dark zones in the light-emitting region formed in space by the emitted light rays after the light emitted from the subpixel is dispersed by the M dispersive structures. That is, in the embodiment of the present invention, a region corresponding to the M dispersive structures is used as one repeat unit, and the emitted light rays from this region form a continuous light-emitting region in space, and the brightness at each viewpoint of this region is the same. Therefore, the human eye does not see "dark zones" when moving through the visible space, and the problem of macroscopic moiré fringes is alleviated.

[0070] Note that, taking the row direction X shown in FIG. 1 as an example, this row direction X is the left-right direction in the figure, and when the focusing center line of the j-th spectroscopic structure is shifted to the right in the row direction with respect to the first symmetry axis, H2-j is positive,

number

number

[0071] In some embodiments, Vj corresponding to the jth spectroscopic structure in different spectroscopic repeating units are all equal.

[0072] In some embodiments, in one spectroscopic repeat unit, all C's in Vj corresponding to each spectroscopic structure are equal.

[0073] In some embodiments, in one spectroscopic repeat unit, Vj=0 corresponds to one spectroscopic structure, Vj corresponding to the remaining spectroscopic structures is not 0, and Vj corresponding to the remaining spectroscopic structures is not equal to each other.

[0074] In some embodiments, N / M is an integer.

[0075] If N / M is an integer, in some embodiments, each spectral repeating unit corresponds to K columns of pixel islands in a pixel repeating unit row, where K is an integer greater than 1. K / M is an integer.

[0076] In a specific implementation, as shown in Figure 1, M = 4, K = 4, n = 8, and N = K * n = 32. The four spectroscopic structures are A1, A2, A3, and A4, respectively, and each spectroscopic repeat unit includes four sub-regions 031-1, 031-2, 031-3, and 031-4, where A1 corresponds to 031-1, A2 corresponds to 031-2, A3 corresponds to 031-3, and A4 corresponds to 031-4.

[0077] In a specific implementation, when M=4, Vj corresponding to the four spectral structures are selected from the following:

number

[0078] In some embodiments, C=1, and in each spectral repeat unit, a plurality of Vj corresponding to M spectral structures form an arithmetic progression with a common difference of 1 / M. For example, when M=4, in a specific implementation, the Vj corresponding to four spectral structures are arbitrarily selected from the following four consecutive ones:

number

[0079] In a specific implementation, Vj corresponding to the four spectral structures is one of the following combinations: (-3 / 4, -2 / 4, -1 / 4, 0), (-2 / 4, -1 / 4, 0, 1 / 4), (-1 / 4, 0, 1 / 4, 2 / 4), and (0, 1 / 4, 2 / 4, 3 / 4). Vj in the above combinations is randomly assigned to the four spectral structures. For example, if the combination (0, 1 / 4, 2 / 4, 3 / 4) is selected and randomly assigned to the four spectral structures, a total of 24 possible assignments are possible.

[0080] As an example, as shown in FIG. 1, the focusing center line 016 of the dispersing structure A1 is not shifted relative to the first symmetry axis 017 of the subregion 031-1, i.e., H2-1 = 0. The focusing center line 016 of the dispersing structure A2 is shifted to the right by (1 / 4)h1 relative to the first symmetry axis 017 of the subregion 031-2, i.e., H2-2 = (1 / 4)h1. The focusing center line 016 of the dispersing structure A3 is shifted to the right by (2 / 4)h1 relative to the first symmetry axis 017 of the subregion 031-3, i.e., H2-3 = (2 / 4)h1. The focusing center line 016 of the dispersing structure A4 is shifted to the right by (3 / 4)h1 relative to the first symmetry axis 017 of the subregion 031-4, i.e., H2-4 = (3 / 4)h1. The first distance between adjacent spectroscopic structures A1 and A2 is L1-1, the first distance between adjacent spectroscopic structures A2 and A3 is L1-2, the first distance between adjacent spectroscopic structures A3 and A4 is L1-3, and the first distance between adjacent spectroscopic structures A4 and A1 is L1-4. L1-1, L1-2, L1-3, and L1-4 are not completely equal, and L1-1 = H3 + (1 / 4)h1 = L1-2 = L1-3, and L1-4 = H3 - (3 / 4)h1.

[0081] 1 illustrates the distance using an example where n=8, but in a specific implementation, M=4, K=4, and n=16 may be used. Next, an example will be described in which Vj of the four spectral structures is (0, 1 / 4, 2 / 4, 3 / 4).

[0082] Solution one: The focusing center line of the dispersing structure A1 is not shifted relative to the first symmetry axis of its corresponding sub-region. The focusing center line of the dispersing structure A2 is shifted (1 / 4)h1 to the right relative to the first symmetry axis of its corresponding sub-region. The focusing center line of the dispersing structure A3 is shifted (2 / 4)h1 to the right relative to the first symmetry axis of its corresponding sub-region. The focusing center line of the dispersing structure A4 is shifted (3 / 4)h1 to the right relative to the first symmetry axis of its corresponding sub-region. The first distance between adjacent dispersing structures A1 and A2 is L1-1, the first distance between adjacent dispersing structures A2 and A3 is L1-2, the first distance between adjacent dispersing structures A3 and A4 is L1-3, and the first distance between adjacent dispersing structures A4 and A1 is L1-4. The width of the pixel island in the row direction is 181.8 micrometers (μm), i.e., H3 = 181.8 μm, h1 = 11.3625 μm. L1-1 = H3 + (1 / 4)h1 = L1-2 = L1-3 = 184.640625 μm, and L1-4 = H3 - (3 / 4)h1 = 173.278125 μm.

[0083] Solution 2: The focusing center line of the dispersing structure A1 is not shifted relative to the first symmetry axis of its corresponding sub-region. The focusing center line of the dispersing structure A2 is shifted by (1 / 4)h1 to the right relative to the first symmetry axis of its corresponding sub-region. The focusing center line of the dispersing structure A3 is shifted by (3 / 4)h1 to the right relative to the first symmetry axis of its corresponding sub-region. The focusing center line of the dispersing structure A4 is shifted by (2 / 4)h1 to the right relative to the first symmetry axis of its corresponding sub-region. The first distance between adjacent dispersing structures A1 and A2 is L1-1, the first distance between adjacent dispersing structures A2 and A3 is L1-2, the first distance between adjacent dispersing structures A3 and A4 is L1-3, and the first distance between adjacent dispersing structures A4 and A1 is L1-4. The width of the pixel island in the row direction is 181.8 micrometers (μm), i.e., H3 = 181.8 μm, h1 = 11.3625 μm. L1-1 = H3 + (1 / 4) h1 = 184.640625 μm, L1-2 = H3 + (2 / 4) h1 = 187.48125 μm, L1-3 = H3 - (1 / 4) h1 = 178.959375 μm, and L1-4 = H3 - (2 / 4) h1 = 176.11875 μm.

[0084] To better understand this solution, the following will take the main-plane viewing angle as an example to explain that the light-emitting areas of each sub-pixel in the K pixel islands are spatially offset, and that the emitted light from the light-emitting areas of each sub-pixel in the K pixel islands forms a continuous light-emitting area in space after being dispersed by the M dispersing structures.

[0085] The viewing angles include main-parallel viewing angles and parallel viewing angles. The main-parallel viewing angle refers to the viewing angle formed in space after light emitted from a subpixel is dispersed by the dispersing structure directly above it. The parallel viewing angle refers to the viewing angle formed in space by the dispersing structure next to the dispersing structure directly above it. For example, if the light emitted from a subpixel passes through the first dispersing structure adjacent to the dispersing structure directly above it, it is called a primary parallel viewing angle, and if the light passes through the second dispersing structure adjacent to the dispersing structure directly above it, it is called a secondary parallel viewing angle, and so on.

[0086] It should be noted that the space in the phrase "the light-emitting regions of the sub-pixels in the K pixel islands are arranged to be shifted in space" refers to the visible space of the display device.

[0087] In a display device provided by an embodiment of the present invention, M dispersive structures are arranged corresponding to K pixel islands, and the light-emitting regions of each subpixel in the K pixel islands are offset in space. Because the dimensions of the dispersive structures in the row direction are small, the human eye cannot specifically identify which dispersive structure a light beam comes from for the K pixel islands corresponding to the M dispersive structures. Therefore, to the human eye, the light beams emitted from the K pixel islands dispersed by the M dispersive structures above them appear to form a continuous light-emitting region in space, and the human eye does not see any "dark zones" when moving through the visible space, thereby reducing the problem of macroscopic Moiré fringes.

[0088] In a specific implementation, in M ​​dispersive structures arranged in a row direction, among a plurality of sub-pixels corresponding to each dispersive structure, the difference in viewpoint between two adjacent sub-pixels is M.

[0089] In some embodiments, K=4, M=4, and N=16, and the aperture ratio of the subpixel is 1 / 4. Optical path diagrams of K columns of pixel islands are shown in FIGS. 2 and 3. In the four columns of pixel islands in the pixel repeat unit rows corresponding to the four spectral structures, each row of the four columns of pixel islands includes 16 subpixels, labeled as the first subpixel 1 through the sixteenth subpixel 16, respectively, and the number of each subpixel represents its corresponding viewpoint. The four pixel islands are the first pixel island S1, the second pixel island S2, the third pixel island S3, and the fourth pixel island S4, respectively. The first pixel island S1 includes the fourth subpixel 4, the eighth subpixel 8, the twelfth subpixel 12, and the sixteenth subpixel 16. The second pixel island S2 includes the third subpixel 3, the seventh subpixel 7, the eleventh subpixel 11, and the fifteenth subpixel 15. The third pixel island S3 includes the second subpixel 2, the sixth subpixel 6, the tenth subpixel 10, and the fourteenth subpixel 14. The fourth pixel island S4 includes the first subpixel 1, the fifth subpixel 5, the ninth subpixel 9, and the thirteenth subpixel 13. The dispersing structures corresponding to the 16 subpixels are labeled A1 to A4, respectively. The focusing center line of dispersing structure A1 is not shifted with respect to the first symmetry axis of its corresponding subregion. The focusing center line of dispersing structure A2 is shifted (1 / 4)h1 to the right with respect to the first symmetry axis of its corresponding subregion. The focusing center line of dispersing structure A3 is shifted (2 / 4)h1 to the right with respect to the first symmetry axis of its corresponding subregion. The focusing center line of dispersing structure A4 is shifted (3 / 4)h1 to the right with respect to the first symmetry axis of its corresponding subregion. As shown in FIG. 2, the dispersing structure A1 covers the fourth subpixel 4, the eighth subpixel 8, the twelfth subpixel 12, and the sixteenth subpixel 16. The dispersing structure A2 covers the third subpixel 3, the seventh subpixel 7, the eleventh subpixel 11, and the fifteenth subpixel 15. The dispersing structure A3 covers the second subpixel 2, the sixth subpixel 6, the tenth subpixel 10, and the fourteenth subpixel 14. The dispersing structure A4 covers the first subpixel 1, the fifth subpixel 5, the ninth subpixel 9, and the thirteenth subpixel 13. As shown in FIG. 2, the relative positions of the subpixels and the dispersing structures within the four pixel islands do not form a repeating unit.When patching each subpixel in viewpoint order while maintaining the relative position of each subpixel and the spectral structure, as shown in Figure 3, after patching the subpixels corresponding to each spectral structure, the positions of the subpixels are complementary, i.e., there is no gap between each subpixel, and the relative positions with the spectral structure are offset to form a complementary arrangement, as shown in Figure 3. Correspondingly, the light-emitting areas of each subpixel within the four pixel islands are offset in space, and the light-emitting areas of each subpixel within the four pixel islands are also offset in space to form a complementary arrangement. As shown in Figure 2, there are gaps between the subpixels O8, so the light emission angles in space of adjacent subpixels corresponding to the same spectral structure after passing through the same spectral structure A are discontinuous. However, because the relative positions of each subpixel within the four pixel islands and the four spectral structures A are offset, the light-emitting areas of each subpixel within the four pixel islands are offset in space, and the light emission angles of each spectral structure A are also offset and complementary. Because the dimensions of the dispersing structure A are very small, the human eye cannot specifically identify which dispersing structure A the light ray originates from. Therefore, as shown in Figure 3, to the human eye, the emitted light rays after the light emitted from the 16 subpixels in the four pixel islands is dispersed by the four dispersing structures appear to form a continuous light-emitting area in space, and the human eye does not see any "dark zones" when moving through space.

[0090] The continuity of paraparallel viewing angles is based on the same principle as the continuity of the main paraparallel viewing angles described above. Two discontinuous first-order paraparallel viewing angles, formed by K pixel islands passing through adjacent spectral structures, are complementarily combined to form a single continuous first-order paraparallel viewing angle. Furthermore, in the horizontal direction (row direction), the width of the M spectral structures is equal to the width of the K columns of pixel islands in the pixel repeat unit row, so the boundaries of the main paraparallel viewing angles and the paraparallel viewing angles are parallel. Because the human eye cannot distinguish the distance between the boundaries of the main paraparallel viewing angles and the paraparallel viewing angles, the main paraparallel viewing angles and the paraparallel viewing angles appear continuous. Based on the same principle, the first-order paraparallel viewing angles and the secondary paraparallel viewing angles are also continuous, as are the secondary paraparallel viewing angles and the tertiary paraparallel viewing angles, and so on. This provides a continuous viewing angle.

[0091] In some embodiments, K=4, M=4, and N=16, and the aperture ratio of the subpixel is 3 / 4. Optical path diagrams of K pixel islands in a pixel repeat unit row are shown in FIGS. 4 and 5. The four pixel islands corresponding to the four spectral structures include 16 subpixels, labeled as the first subpixel 1 through the sixteenth subpixel 16, respectively, with the number of each subpixel representing its corresponding viewpoint. The four pixel islands are the first pixel island S1, the second pixel island S2, the third pixel island S3, and the fourth pixel island S4, respectively. The first pixel island S1 includes the fourth subpixel 4, the eighth subpixel 8, the twelfth subpixel 12, and the sixteenth subpixel 16. The second pixel island S2 includes the third subpixel 3, the seventh subpixel 7, the eleventh subpixel 11, and the fifteenth subpixel 15. The third pixel island S3 includes the second subpixel 2, the sixth subpixel 6, the tenth subpixel 10, and the fourteenth subpixel 14. The fourth pixel island S4 includes the first subpixel 1, the fifth subpixel 5, the ninth subpixel 9, and the thirteenth subpixel 13. The spectral structures corresponding to the 16 subpixels are labeled A1 to A4, respectively. The focusing centerline of the spectral structure A1 is not shifted relative to the first symmetry axis of its corresponding subregion. The focusing centerline of the spectral structure A2 is shifted (1 / 4)h1 to the right relative to the first symmetry axis of its corresponding subregion. The focusing centerline of the spectral structure A3 is shifted (2 / 4)h1 to the right relative to the first symmetry axis of its corresponding subregion. The focusing centerline of the spectral structure A4 is shifted (3 / 4)h1 to the right relative to the first symmetry axis of its corresponding subregion. As shown in FIG. 4, the spectral structure A1 covers the fourth subpixel 4, the eighth subpixel 8, the twelfth subpixel 12, and the sixteenth subpixel 16. The dispersive structure A2 covers the third subpixel 3, the seventh subpixel 7, the eleventh subpixel 11, and the fifteenth subpixel 15. The dispersive structure A3 covers the second subpixel 2, the sixth subpixel 6, the tenth subpixel 10, and the fourteenth subpixel 14. The dispersive structure A4 covers the first subpixel 1, the fifth subpixel 5, the ninth subpixel 9, and the thirteenth subpixel 13. As shown in FIG. 4, the relative positions of the subpixels and the dispersive structures within the four pixel islands do not form a repeating unit.When patching each subpixel in viewpoint order while maintaining the relative position of each subpixel and the spectral structure, as shown in Figure 5, after patching the subpixels corresponding to each spectral structure, the subpixel positions overlap and the relative positional relationship with the spectral structure is shifted, forming an overlapping arrangement. Correspondingly, the light-emitting areas of each subpixel in the four pixel islands are shifted in space, and the light-emitting areas of each subpixel in the four pixel islands are also shifted in space, forming an overlapping arrangement. As shown in Figure 4, because there are gaps between the subpixels O8, the light emission angles in space of light emitted from adjacent subpixels corresponding to the same spectral structure after passing through the same spectral structure A are discontinuous. However, because the relative positions of each subpixel in the four pixel islands and the four spectral structures A are shifted so as to overlap uniformly, the light-emitting areas of each subpixel in the four pixel islands are uniformly overlapping in space, and the light emission angles of each spectral structure A are also shifted so as to overlap uniformly. Because the dimensions of the dispersing structure A are very small, the human eye cannot specifically identify which dispersing structure A the light ray originates from. Therefore, as shown in Figure 5, to the human eye, the emitted light rays after the light emitted from the 16 subpixels in the four pixel islands is dispersed by the four dispersing structures appear to form a continuous light-emitting area in space, and the human eye does not see any "dark zones" when moving through space.

[0092] 5, in the row direction, the ratio of the total width n×h1 of the n subpixel aperture regions to the width h2 of the pixel island is i / M, where i is an integer greater than 1 and equal to or less than M−1. That is, the aperture ratio of the subpixels in the pixel island is i / M. By setting it in this way, the subpixels below each dispersing repeat unit are shifted relative to the position of the corresponding dispersing structure so as to uniformly overlap, and the light-emitting regions of the subpixels in the K pixel islands uniformly overlap in space, that is, the optical paths of each viewpoint uniformly overlap, which similarly eliminates macroscopic moiré fringes and improves the display effect.

[0093] In a specific implementation, when the light-emitting areas of the subpixels in the K pixel islands uniformly overlap in space, the ratio of the area of ​​the overlapping area of ​​the light-emitting areas of two adjacent subpixels to the area of ​​the light-emitting area of ​​one of the subpixels is (i-1) / i, and the ratio of the area of ​​the overlapping area of ​​the light-emitting areas of two adjacent subpixels to the area of ​​one of the subpixels is (i-1) / M.

[0094] In the row direction, when the ratio of the total width n×h1 of the n subpixel aperture regions to the width h2 of the pixel island is 1 / M, i.e., when i=1, the emissive regions of the subpixels do not overlap in space. When i=2, the ratio of the area of ​​the overlapping region of the emissive regions of two adjacent subpixels to the area of ​​one of those subpixels is 1 / 2, and the ratio of the area of ​​the overlapping region of the emissive regions of two adjacent subpixels to the area of ​​one of those subpixels is 1 / M. When i=3, the ratio of the area of ​​the overlapping region of the emissive regions of two adjacent subpixels to the area of ​​one of those subpixels is 2 / 3, and the ratio of the area of ​​the overlapping region of the emissive regions of two adjacent subpixels to the area of ​​one of those subpixels is 2 / M. When i=4, the ratio of the area of ​​the overlapping region of the light-emitting regions of two adjacent subpixels to the area of ​​the light-emitting region of one of those subpixels is 3 / 4, and the ratio of the area of ​​the overlapping region of the light-emitting regions of two adjacent subpixels to the area of ​​one of those subpixels is 3 / M. When i=M-1, the ratio of the area of ​​the overlapping region of the light-emitting regions of two adjacent subpixels to the area of ​​one of those subpixels is (M-2) / (M-1), and the ratio of the area of ​​the overlapping region of the light-emitting regions of two adjacent subpixels to the area of ​​one of those subpixels is (M-2) / M. This applies below, and details are omitted.

[0095] 4 illustrates an example in which the ratio of the total width of the n subpixel aperture regions to the width of the pixel island in the row direction is (M-1) / M, i.e., 3 / 4. In other words, in FIG. 4, the aperture ratio of the subpixels in the pixel island is 3 / 4. When the aperture ratio of the subpixels in the pixel island is (M-1) / M, the condition that the light-emitting regions of each subpixel in the K pixel islands uniformly overlap in space in the row direction can be satisfied, while the aperture ratio of the subpixels can be maximized. Of course, in a specific implementation, the aperture ratio of the subpixels in the pixel island may be 2 / 4.

[0096] In some embodiments, as shown in Figure 1, the centers of sub-pixels 08 in the same column in any two adjacent pixel repeat unit rows 013 are collinear in the column direction Y. That is, in Figure 1, the sub-pixels in multiple pixel repeat unit rows 013 are not offset from one another.

[0097] In Scheme 1 and Scheme 2, the centers of the sub-pixels in the same column in any two adjacent pixel repeat unit rows are on the same line in the column direction.

[0098] In addition, when the centers of subpixels in the same column in different pixel repeat unit rows are on the same straight line in the column direction, if there is a large difference in the width of the subpixel aperture regions, the emitted light rays after the light emitted from the subpixels in the K pixel islands is dispersed by the M dispersing structures may form discontinuous light-emitting regions in space, i.e., dark zones may occur, and macroscopic moiré fringes may occur.

[0099] Simulations were performed for solution 1 with a subpixel aperture ratio of 3 / 4. When there was no brightness variation, the overlapping angular spectrum of each subpixel was shown in Figure 6. The maximum subpixel width in the row direction was 8.52 μm. Because there was no brightness variation, no Moiré fringes were generated due to brightness variation. However, when the subpixel aperture varied by 1.5 μm, i.e., the absolute value of the subpixel width difference was 1.5 μm, the maximum subpixel width in the row direction was 10.02 μm, as shown in Figure 7. This resulted in brightness variation and Moiré fringes. Figure 8 shows the relationship between subpixel aperture width deviation and Moiré fringe intensity. To achieve Moiré fringe intensity of less than 1%, in a specific implementation, the variation in subpixel aperture width must be less than ±0.15 μm, i.e., the absolute value of the width difference between different subpixels in the row direction must be less than 0.15 μm.

[0100] In order to avoid Moiré fringes due to width variations in the subpixel column direction, in some embodiments, as shown in FIG. 9 , the ratio Jj of the vector H1 of the displacement of the subpixel 08 in the row direction X with respect to the first symmetry axis 017 in the row direction X to the width h1 of the subpixel 08 in the row direction X is

number

[0101] In a specific implementation, as shown in FIG. 9, the subpixel 08 in the second pixel repeat unit row 013-2 is shifted to the right in the row direction X with respect to the first symmetry axis 017. In FIG. 9, M=4, C=1, H1=(1 / 8)h1, and J2=1 / 8. That is, the display device provided by the embodiment of the present invention can avoid Moiré fringes caused by width variations in the subpixel column direction by simply shifting only one of the pixel repeat unit rows with respect to the first symmetry axis. This avoids Moiré fringes while not excessively increasing the difficulty of designing the subpixel layout of the display device.

[0102] Note that the vector by which a subpixel in a pixel repeat unit row is shifted in the row direction relative to the first axis of symmetry is equal to the vector by which a subpixel in a pixel repeat unit row is shifted in the row direction relative to the subregion boundary, and both are H1. To intuitively show the relationship of subpixel shifts in pixel repeat unit rows, Figure 9 only shows the vector by which subpixel 08 in pixel repeat unit row 013 is shifted in the row direction X relative to the subregion 031 boundary.

[0103] In a specific implementation, a simulation was performed using the setting method shown in Figure 9. When there is no variation in the subpixel aperture, the overlap angle spectrum of each subpixel is shown in Figure 10. The maximum width of the subpixel in the row direction is 8.52 μm, with no brightness variation and no Moiré fringes. When the subpixel aperture varies by 1.5 μm, the overlap angle spectrum of each subpixel is shown in Figure 11. The maximum width of the subpixel in the row direction is 10.02 μm, with no brightness variation and no Moiré fringes. Figure 12 shows the relationship between subpixel aperture width deviation and Moiré fringe intensity. Even when the subpixel aperture variation is ±1.5 μm, the Moiré fringe intensity is less than 1%. From the trend in Figure 11, it can be determined that the tolerance for subpixel width variation reaches ±2 μm.

[0104] In a specific implementation, when the aperture ratio of the sub-pixel is i / M, the sub-pixels in the pixel repeat unit row can be shifted in a different manner with respect to the first symmetry axis to reduce the Moire fringes.

[0105] In some embodiments, as shown in FIG. 13, a plurality of pixel repeating unit rows 013 are divided into a plurality of pixel repeating unit groups 014, and each pixel repeating unit group 014 includes M pixel repeating unit rows 013.

[0106] In the pixel repeating unit group 014, the ratio Jj of the vector H1-j of the displacement of the subpixel in the j-th pixel repeating unit row 013 in the row direction X relative to the first axis of symmetry 017 to the width h1 of the subpixel 08 in the row direction X is given by

number

[0107] In the display device provided by the embodiment of the present invention, in a pixel repeat unit group, the subpixels in a pixel repeat unit row are shifted in the row direction with respect to the first symmetry axis, i.e., the subpixels between different subpixel rows are shifted in the row direction, so that M pixel repeat unit rows can be used as one repeat unit of the pixel repeat unit row array. This prevents the occurrence of dark zones in the luminous region formed in space by the emitted light beams after the light emitted from the subpixels is split by the M splitting structures when a single pixel repeat unit row is used as the repeat unit of the pixel repeat unit row array. That is, in the display device provided by the embodiment of the present invention, the emitted light beams passing through each splitting repeat unit of the M pixel repeat unit rows form a continuous luminous region in space, and the brightness of each viewpoint in this region is the same, so that the human eye does not see "dark zones" when moving through the visible space, and the problem of macroscopic Moiré fringes can be reduced.

[0108] Note that, taking the row direction X shown in FIG. 13 as an example, this row direction X is the left-right direction in the figure, and when a subpixel in the j-th pixel repeat unit row 013 is shifted to the right in the row direction X with respect to the first symmetry axis 017, H1-j is positive,

[0109] In some embodiments, in a pixel repeating unit group, Jj=0 corresponding to one pixel repeating unit row, and Jj=0 corresponding to the remaining pixel repeating unit rows.

[0110] In some embodiments, in a pixel repeat unit group 014, Jj corresponding to multiple pixel repeat unit rows 013 are not equal to each other, and the absolute value of the difference between Jj corresponding to any two pixel repeat unit rows is not an integer greater than or equal to 1. In this way, it is possible to further avoid the occurrence of dark zones in the light emitting region formed in space by the emitted light rays after the light emitted from the subpixel is dispersed by the M dispersing structures, and to prevent the occurrence of macroscopic moiré fringes.

[0111] In some embodiments, in a subunit, the ratio ΔJ of the displacement vector in the row direction of the c-th subpixel in at least some of two adjacent pixel repeat unit rows to the width of the subpixel in the row direction is

number

number

[0112] In addition, when the difference between two Jj is M or an integer multiple of M, for example, when Jj is -5 / 4 or -1 / 4, respectively, the dark zone shielding effect when Jj=-5 / 4 is equivalent to the dark zone shielding effect when Jj=-1 / 4.

[0113] In some embodiments, C=1, i.e., the vector of the subpixel offset relative to the first symmetry axis does not exceed the width of the subpixel in the row direction X. This is advantageous for preventing the subpixel offset distance from becoming excessive, while avoiding a single pixel repeat unit row becoming a repeat unit of an array of pixel repeat unit rows, and for rationally utilizing the space of the display panel.

[0114] In some embodiments, when C=1, in each pixel repeating unit group, a plurality of Jj corresponding to M pixel repeating unit rows form an arithmetic progression with a common difference of 1 / M.

[0115] When the aperture ratio of the subpixel is 3 / 4, i.e., M=4, Jj can be selected from the following: -3 / 4, -2 / 4, -1 / 4, 0, 1 / 4, 2 / 4, 3 / 4. The multiple Jj corresponding to the M pixel repeat unit rows form an arithmetic progression, so one of the four Jj can be selected from the following combinations: (-3 / 4, -2 / 4, -1 / 4, 0), (-2 / 4, -1 / 4, 0, 1 / 4), (-1 / 4, 0, 1 / 4, 2 / 4), (0, 1 / 4, 2 / 4, 3 / 4). After selecting one Jj combination, the four Jj can be randomly assigned to the four pixel repeat unit rows, resulting in a total of 24 possible assignments. The following describes the combination (-1 / 4, 0, 1 / 4, 2 / 4) as an example.

[0116] Solution three: 13, the first pixel repeat unit row 013-1 has no offset with respect to the first axis of symmetry 017, i.e., H1-1=0, J1=0. The second pixel repeat unit row 013-2 has an offset of (1 / 4)h1 to the right with respect to the first axis of symmetry 017, i.e., H1-2=(1 / 4)h1, J2=1 / 4, and correspondingly, the second pixel repeat unit row 013-2 is offset to the right by (1 / 4)h1 with respect to the first pixel repeat unit row 013-1. The third pixel repeat unit row 013-3 has an offset of (2 / 4)h1 to the right with respect to the first axis of symmetry 017, i.e., H1-3=(2 / 4)h1, J3=2 / 4, and correspondingly, the third pixel repeat unit row 013-3 is offset to the right by (2 / 4)h1 with respect to the first pixel repeat unit row 013-1. The fourth pixel repeat unit row 013-4 is shifted to the left by (1 / 4)h1 relative to the first axis of symmetry 017, i.e., H1-4=(-1 / 4)h1, J4=-1 / 4, and correspondingly, the fourth pixel repeat unit row 013-4 is shifted to the left by (1 / 4)h1 relative to the first pixel repeat unit row 013-1.

[0117] In some embodiments, as shown in Figure 13, the focusing center lines 016 overlap with the first symmetry axis 017. In Figure 13, the distance L1 between adjacent focusing center lines 016 is equal to the distance H3 between adjacent first symmetry axes 017, and is equal to the width in the row direction X of the pixel island S. In a specific implementation, if the width in the row direction X of the pixel island S is 181.8 μm, then in Figure 13, L1-1 = L1-2 = L1-3 = L1-4 = 181.8 μm.

[0119] This makes it possible to avoid discontinuity in the light-emitting regions formed in space by the emitted light rays after the light emitted from the subpixels has been dispersed by the M dispersing structures, due to differences in the row-direction widths of the subpixel aperture regions, i.e., fluctuations in the row direction of the subpixel aperture regions, and thus prevents the occurrence of macroscopic moiré fringes.

[0120] In a specific implementation, C=1. As shown in FIG. 14 , in each light-splitting repeating unit 03, the ratio Vj of the vector H2-1, which is the displacement of the focusing center line 016 of the second light-splitting structure A2 in the row direction X relative to the first symmetry axis 017, to the width h1 of the sub-pixel 08 in the row direction X, is:

[0122] 1 to 14 illustrate a specific example in which the aperture ratio of the subpixel is not less than 0.9 / M and not more than 1. Of course, the aperture ratio of the subpixel may be in other ranges.

[0123] In some embodiments, each pixel island includes n subpixels spaced apart in the row direction, where n is an integer greater than 1. The subpixels include subpixel aperture areas, and the ratio of the total width of the n subpixel aperture areas to the width of the pixel island in the row direction is 0.9 / (M×M′) or more and 1 or less. That is, the aperture ratio of the subpixel is 0.9 / (M×M′) or more and 1 or less.

[0124] In some embodiments, the ratio of the width of the subpixel aperture region to the width of the pixel island in the row direction is i / (M×M′), where i is an integer greater than or equal to 1 and less than or equal to M×M′−1. That is, the aperture ratio of the subpixel is i / (M×M′).

[0125] In some embodiments, as shown in FIG. 15, a plurality of pixel repeating unit rows 013 are divided into a plurality of pixel repeating unit groups 014, and each pixel repeating unit group 014 includes M′ pixel repeating unit rows 013.

[0126] In a specific implementation, when the aperture ratio of a subpixel is i / (M×M′), in a spectral repeat unit, the Vj corresponding to the M spectral structures are not equal to each other, and in a pixel repeat unit group, the subpixels 08 in any two adjacent pixel repeat unit rows 013 are shifted in the row direction X. By using M spectral structures as one repeat unit of the spectral structure array and M′ pixel repeat unit rows as the repeat unit of the pixel repeat unit row array, the emitted light beams that pass through the M spectral structures in each group of M′ pixel repeat unit rows form a continuous light-emitting area in space, and the brightness of each viewpoint in this area is the same, so that the human eye does not see any “dark zones” when moving through the visible space, and the occurrence of macroscopic Moiré fringes can be avoided.

[0127] In some embodiments, as shown in FIG. 15 , in the dispersing repeat unit 03, a ratio Vj of a vector H2, which is a displacement of the focusing center line 016 of the j-th dispersing structure Aj in the row direction X with respect to the first symmetry axis 017, to a width h1 of the subpixel 08 in the row direction X, is expressed as follows:

number

[0128] In the pixel repeating unit group 014, the ratio Jj' of the vector H2 of the displacement of the subpixel 08 in the j'-th pixel repeating unit row 013-j' in the row direction X relative to the first axis of symmetry 017 to the width h1 of the subpixel 08 in the row direction X is given by

number

[0129] Here, j is an integer greater than or equal to 1 and less than M, j' is an integer greater than or equal to 1 and less than M', C and C' are both integers greater than 0, E'' is an integer greater than or equal to 0 and less than M, and E''' is an integer greater than or equal to 0 and less than M'.

[0130] In some embodiments, in a dispersing repeat unit, the Vj corresponding to the M dispersing structures are not equal to one another. That is, the vectors of the focal lines shifted in the row direction relative to the first symmetry axis are not equal, so a single dispersing structure does not constitute a repeat unit of an array of multiple dispersing structures. This prevents the occurrence of dark zones in the light-emitting region formed in space by the emitted light beams after the light emitted from the subpixel is dispersed by the M dispersing structures when a single dispersing structure constitutes a repeat unit of an array of multiple dispersing structures. That is, in embodiments of the present invention, a region corresponding to the M dispersing structures is used as one repeat unit, and the emitted light beams from this region form a continuous light-emitting region in space. Furthermore, because the brightness at each viewpoint in this region is the same, the human eye does not see any "dark zones" when moving through visible space, thereby reducing the problem of macroscopic moiré fringes.

[0131] In some embodiments, Vj corresponding to the jth spectroscopic structure in different spectroscopic repeating units are all equal.

[0132] In some embodiments, in one spectroscopic repeat unit, all C's in Vj corresponding to each spectroscopic structure are equal.

[0133] In some embodiments, in one spectroscopic repeat unit, Vj=0 corresponds to one spectroscopic structure, Vj corresponding to the remaining spectroscopic structures is not 0, and Vj corresponding to the remaining spectroscopic structures is not equal to each other.

[0134] In some embodiments, in a pixel repeating unit group, Jj'=0 corresponding to one pixel repeating unit row, and Jj'=0 corresponding to the remaining pixel repeating unit rows.

[0135] In some embodiments, in a pixel repeat unit group 014, Jj' corresponding to multiple pixel repeat unit rows 013 are not equal to each other, and the absolute value of the difference between Jj' corresponding to any two pixel repeat unit rows is not an integer greater than or equal to 1. In this way, it is possible to further avoid the occurrence of dark zones in the light emitting region formed in space by the emitted light rays after the light emitted from the subpixel is dispersed by the M dispersing structures, and to prevent the occurrence of macroscopic moiré fringes.

[0136] In some embodiments, C=C′=1; In each dispersing repeating unit, a plurality of Vj corresponding to M dispersing structures form an arithmetic progression with a common difference of 1 / (M×M′). In each pixel repeating unit group, a plurality of Jj' corresponding to M' pixel repeating unit rows form an arithmetic progression with a common difference of 1 / M'.

[0137] Continuing with the example, where N / M is an integer, in some embodiments, each spectral repeating unit corresponds to K columns of pixel islands in a pixel repeating unit row, where K is an integer greater than 1. K / M is an integer.

[0138] In a specific implementation, the aperture ratio of the subpixel is 5 / 6, M=3, and M'=2. The three splitting structures are A1, A2, and A3, respectively, and each splitting repeat unit includes three sub-regions 031-1, 031-2, and 031-3, where A1 corresponds to 031-1, A2 corresponds to 031-2, and A3 corresponds to 031-3.

[0139] In a specific implementation, when M=3 and C=C'=1, Vj corresponding to three spectral structures are selected from -2 / 6, -1 / 6, 0, 1 / 6, and 2 / 6. Vj corresponding to three spectral structures are one of the following combinations: (-2 / 6, -1 / 6, 0), (-1 / 6, 0, 1 / 6), and (0, 1 / 6, 2 / 6). Vj in the above combinations are randomly assigned to the three spectral structures. Jj' corresponding to two pixel repeat unit rows are selected from -1 / 2, 0, and 1 / 2. Jj' corresponding to two pixel repeat unit groups are one of the following combinations: (-1 / 2, 0), and (0, 1 / 2). Jj' in the above combinations are randomly assigned to the two pixel repeat unit rows. In the following, an example will be described in which the combination of Vj is (0, 1 / 6, 2 / 6) and the combination of Jj' is (0, 1 / 2).

[0140] Solution 4: 15, the focusing center line 016 of the dispersing structure A1 is not shifted relative to the first symmetry axis 017 of the subregion 031-1, i.e., H2-1 = 0. The focusing center line 016 of the dispersing structure A2 is shifted to the right by (1 / 6)h1 relative to the first symmetry axis 017 of the subregion 031-2, i.e., H2-2 = (1 / 6)h1. The focusing center line 016 of the dispersing structure A3 is shifted to the right by (2 / 6)h1 relative to the first symmetry axis 017 of the subregion 031-3, i.e., H2-3 = (2 / 6)h1. The first distance between adjacent dispersing structures A1 and A2 is L1-1, the first distance between adjacent dispersing structures A2 and A3 is L1-2, and the first distance between adjacent dispersing structures A3 and A1 is L1-3. L1-1, L1-2, and L1-3 are not completely equal, with L1-1 = H3 + (1 / 6) h1 = L1-2 and L1-3 = H3 - (1 / 6) h1. The row-direction width of the pixel island and the distance H3 between two adjacent first symmetry axes are both 181.8 μm, with L1-1 = L1-2 = 183.69375 μm and L1-3 = 178.0125 μm. The first pixel repeat unit row 013-1 is not shifted relative to the first symmetry axis 017, i.e., H1-1 = 0 and J1 = 0. The second pixel repeat unit row 013-2 is shifted to the right by (1 / 2) h1 relative to the first symmetry axis 017, i.e., H1-2 = (1 / 2) h1 and J2 = 1 / 2. Correspondingly, the second pixel repeating unit row 013-2 is shifted (1 / 2)h1 to the right relative to the first pixel repeating unit row 013-1.

[0141] Alternatively, in some embodiments, as shown in FIG. 16 , in the dispersing repeat unit 03, a ratio Vj of a vector H2, which is a displacement of the focusing center line 016 of the j-th dispersing structure Aj in the row direction X with respect to the first symmetry axis 017, to a width h1 of the subpixel 08 in the row direction X, is expressed as follows:

[0143] Here, j is an integer greater than or equal to 1 and less than M, j' is an integer greater than or equal to 1 and less than M', C and C' are both integers greater than 0, E'' is an integer greater than or equal to 0 and less than M, and E''' is an integer greater than or equal to 0 and less than M'.

[0144] In some embodiments, in the spectroscopic repeat unit, Vj corresponding to the M spectroscopic structures are not equal to each other.

[0145] In some embodiments, Vj corresponding to the jth spectroscopic structure in different spectroscopic repeating units are all equal.

[0146] In some embodiments, in one spectroscopic repeat unit, all C's in Vj corresponding to each spectroscopic structure are equal.

[0147] In some embodiments, in one spectroscopic repeat unit, Vj=0 corresponds to one spectroscopic structure, Vj corresponding to the remaining spectroscopic structures is not 0, and Vj corresponding to the remaining spectroscopic structures is not equal to each other.

[0148] In some embodiments, in a pixel repeating unit group, Jj'=0 corresponding to one pixel repeating unit row, and Jj'=0 corresponding to the remaining pixel repeating unit rows.

[0149] In some embodiments, in a pixel repeating unit group 014, Jj' corresponding to multiple pixel repeating unit rows 013 are not equal to each other, and the absolute value of the difference between Jj' corresponding to any two pixel repeating unit rows is not an integer greater than or equal to 1.

[0150] In some embodiments, C=C′=1; In each spectroscopic repeating unit, a plurality of Vj corresponding to M spectroscopic structures form an arithmetic progression with a common difference of 1 / M. In each pixel repeating unit group, a plurality of Jj corresponding to M' pixel repeating unit rows form an arithmetic progression with a common difference of 1 / (M×M').

[0151] Continuing with the example, where N / M is an integer, in some embodiments, each spectral repeating unit corresponds to K columns of pixel islands in a pixel repeating unit row, where K is an integer greater than 1. K / M is an integer.

[0152] In a specific implementation, the aperture ratio of the subpixel is 5 / 6, M=3, and M'=2. The three splitting structures are A1, A2, and A3, respectively, and each splitting repeat unit includes three sub-regions 031-1, 031-2, and 031-3, where A1 corresponds to 031-1, A2 corresponds to 031-2, and A3 corresponds to 031-3.

[0153] In a specific implementation, when M=3 and C=C'=1, Vj corresponding to three spectral structures are selected from the following: -2 / 3, -1 / 3, 0, 1 / 3, 2 / 3. Vj corresponding to three spectral structures are one of the following combinations: (-2 / 3, -1 / 3, 0), (-1 / 3, 0, 1 / 3), (0, 1 / 3, 2 / 3). Vj in the above combinations are randomly assigned to the three spectral structures. Jj' corresponding to two pixel repeat unit rows are selected from the following: -1 / 6, 0, 1 / 6. Jj' corresponding to two pixel repeat unit rows are one of the following combinations: (-1 / 6, 0), (0, 1 / 6). Jj' in the above combinations are randomly assigned to the two pixel repeat unit rows. In the following, an example will be described in which the combination of Vj is (0, 1 / 3, 2 / 3) and the combination of Jj' is (0, 1 / 6).

[0154] Solution five: 16, the focusing center line 016 of the dispersing structure A1 is not shifted relative to the first symmetry axis 017 of the subregion 031-1, i.e., H2-1 = 0. The focusing center line 016 of the dispersing structure A2 is shifted to the right by (1 / 3)h1 relative to the first symmetry axis 017 of the subregion 031-2, i.e., H2-2 = (1 / 3)h1. The focusing center line 016 of the dispersing structure A3 is shifted to the right by (2 / 3)h1 relative to the first symmetry axis 017 of the subregion 031-3, i.e., H2-3 = (2 / 3)h1. The first distance between adjacent dispersing structures A1 and A2 is L1-1, the first distance between adjacent dispersing structures A2 and A3 is L1-2, and the first distance between adjacent dispersing structures A3 and A1 is L1-3. L1-1, L1-2, and L1-3 are not completely equal, with L1-1 = H3 + (1 / 3) h1 = L1-2 and L1-3 = H3 - (1 / 3) h1. The row-direction width of the pixel island and the distance H3 between two adjacent first symmetry axes are both 181.8 μm, with L1-1 = L1-2 = 185.5875 μm and L1-3 = 174.225 μm. The first pixel repeat unit row 013-1 is not shifted relative to the first symmetry axis 017, i.e., H1-1 = 0 and J1 = 0. The second pixel repeat unit row 013-2 is shifted to the right by (1 / 6)h1 relative to the first axis of symmetry 017, i.e., H1-2=(1 / 6)h1, J2=1 / 6, and correspondingly, the second pixel repeat unit row 013-2 is shifted to the right by (1 / 6)h1 relative to the first pixel repeat unit row 013-1.

[0155] In the display device provided by the embodiments of the present invention, such as Scheme 4 and Scheme 5, in a pixel repeat unit group, the sub-pixels in any two adjacent pixel repeat unit rows are staggered in the row direction, and in a spectral repeat unit, the Vj corresponding to the M spectral structures are unequal, thereby avoiding discontinuity in the light-emitting areas formed by the sub-pixels passing through the spectral structures due to the staggered arrangement of the sub-pixels in the pixel repeat unit row, and further preventing macroscopic Moiré fringes.

[0156] In a specific implementation, in order to increase the tolerance for variations in the row-direction width of the subpixel aperture regions and avoid the problem of Moiré fringes caused by discontinuities in the light-emitting areas due to variations in the row-direction width of the subpixel aperture regions, the vector by which the focusing center line is shifted relative to the first symmetry axis or the vector by which the subpixel is shifted relative to the first symmetry axis can also be further adjusted.

[0157] In some embodiments, as shown in FIG. 17 , in the dispersing repeat unit 03, a ratio Vj of a vector H2-j, which is a displacement of the focusing center line 016 of the j-th dispersing structure Aj in the row direction X with respect to the first symmetry axis 017, to a width h1 of the subpixel 08 in the row direction X, is expressed as follows:

[0159] In the display device provided by the embodiment of the present invention, the combinations of Jj' corresponding to at least some pixel repeat unit groups are different from the combinations of Jj' corresponding to the remaining pixel repeat unit groups, which prevents discontinuity in the light-emitting areas formed in space by the emitted light rays after the light emitted from the subpixels is dispersed by the M dispersing structures due to differences in the row-direction widths of the subpixel aperture regions, i.e., variations in the row-direction widths of the subpixel aperture regions, and thus prevents the occurrence of macroscopic moiré fringes.

In the second pixel repeating unit group 014-2, the first pixel repeating unit row 013-1 is shifted to the left by (-1 / 12)h1 relative to the first symmetry axis 017, i.e., H1-1=-1 / 12 in this pixel repeating unit group. The second pixel repeat unit row 013-2 is offset to the right by (5 / 12)h1 with respect to the first axis of symmetry 017, i.e., H1-2=5 / 12 in this pixel repeat unit group.

[0183] In a specific implementation, when M=3 and C=C'=1, in two adjacent spectral repeat units, Vj corresponding to the three spectral structures of one spectral repeat unit 03-1 are selected from among -2 / 3, -1 / 3, 0, 1 / 3, and 2 / 3. Vj corresponding to the three spectral structures of the other spectral repeat unit 03-2 are selected from among -11 / 12, -9 / 12, -7 / 12, -5 / 12, -3 / 12, -1 / 12, 1 / 12, 3 / 12, 5 / 12, 7 / 12, 9 / 12, and 11 / 12, for example, 1 / 12, 3 / 12, and 5 / 12, or -1 / 12, 1 / 12, and 3 / 12. Jj' corresponding to two pixel repeat unit groups are selected from among -1 / 6, 0, and 1 / 6. In the following, an example will be described in which the combination of Vj corresponding to one spectral repeat unit is (0, 1 / 3, 2 / 3), the combination of Vj corresponding to another spectral repeat unit is (1 / 12, 5 / 12, 9 / 12), and the combination of Jj' is (0, 1 / 6).

[0184] Solution eight: As shown in FIG. 19, in two adjacent spectral repeat units, In the first dispersing repeat unit 03-1, the focusing center line 016 of the dispersing structure A1 is not shifted relative to the first symmetry axis 017 of the subregion 031-1, i.e., H2-1 = 0. The focusing center line 016 of the dispersing structure A2 is shifted to the right by (1 / 3)h1 relative to the first symmetry axis 017 of the subregion 031-2, i.e., H2-2 = (1 / 3)h1.

In the second dispersing repeat unit 03-2, the focusing center line 016 of the dispersing structure A1 is shifted 1 / 12 to the right with respect to the first symmetry axis 017 of the subregion 031-1, i.e., H2-1 = (1 / 12)h1. The focusing center line 016 of the dispersing structure A2 is shifted (5 / 12)h1 to the right with respect to the first symmetry axis 017 of the subregion 031-2, i.e., H2-2 = (5 / 12)h1.

[0185] The first distance between the spectroscopic structure A1 and the spectroscopic structure A2 in the first spectroscopic repeating unit 03-1 is L1-1, the first distance between the spectroscopic structure A2 and the spectroscopic structure A3 in the first spectroscopic repeating unit 03-1 is L1-2, the first distance between the spectroscopic structure A3 in the first spectroscopic repeating unit 03-1 and the spectroscopic structure A1 in the second spectroscopic repeating unit 03-2 is L1-3, the first distance between the spectroscopic structure A1 and the spectroscopic structure A2 in the second spectroscopic repeating unit 03-2 is L1-4, the first distance between the spectroscopic structure A2 and the spectroscopic structure A3 in the second spectroscopic repeating unit 03-2 is L1-5, and the first distance between the spectroscopic structure A3 in the second spectroscopic repeating unit 03-2 and the spectroscopic structure A1 of the next spectroscopic repeating unit 03 is L1-6. The row direction width of the pixel island and the distance H3 between two adjacent first symmetry axes are both 181.8 μm, with L1-1=L1-2=L1-4=L1-5=185.5875 μm, L1-3=175.171875 μm, and L1-6=173.278125 μm. The first pixel repeat unit row 013-1 has no offset relative to the first axis of symmetry 017, i.e., H1-1 = 0, J1 = 0. The second pixel repeat unit row 013-2 has an offset of (1 / 6)h1 to the right relative to the first axis of symmetry 017, i.e., H1-2 = (1 / 6)h1, J2 = 1 / 6, and correspondingly, the second pixel repeat unit row 013-2 is offset to the right by (1 / 6)h1 relative to the first pixel repeat unit row 013-1.

[0187] In the display device provided by the embodiment of the present invention, the combinations of Jj' corresponding to at least some pixel repeat unit groups are different from the combinations of Jj' corresponding to the remaining pixel repeat unit groups, which prevents discontinuity in the light-emitting areas formed in space by the emitted light rays after the light emitted from the subpixels is dispersed by the M dispersing structures due to differences in the row-direction widths of the subpixel aperture regions, i.e., variations in the row-direction widths of the subpixel aperture regions, and thus prevents the occurrence of macroscopic moiré fringes.

[0188] In some embodiments, in each spectroscopic repeat unit, Vj corresponding to the M spectroscopic structures are not equal to one another. In different spectroscopic repeat units, Vj corresponding to the j-th spectroscopic structure are all equal.

[0191] In a specific implementation, the case where the aperture ratio of the subpixel is 5 / 6, M=3, and M'=2 will be described as an example. The three light-splitting structures are A1, A2, and A3, respectively, and each light-splitting repeating unit includes three sub-regions 031-1, 031-2, and 031-3, where A1 corresponds to 031-1, A2 corresponds to 031-2, and A3 corresponds to 031-3.

[0192] In a specific implementation, when M=3 and C=C'=1, Vj corresponding to the three spectral structures are selected from -2 / 3, -1 / 3, 0, 1 / 3, 2 / 3. Jj' corresponding to the second pixel repeat unit group is selected from -11 / 12, -9 / 12, -7 / 12, -5 / 12, -3 / 12, -1 / 12, 1 / 12, 3 / 12, 5 / 12, 7 / 12, 9 / 12, 11 / 12. Jj' corresponding to the remaining pixel repeat unit groups are selected from -1 / 6, 0, 1 / 6. In the following, an example will be described in which the combination of Vj is (0, 1 / 3, 2 / 3), the combination of Jj' corresponding to the second pixel repeat unit group is (-1 / 12, 1 / 12), and the combination of Jj' corresponding to the remaining pixel repeat unit groups is (0, 1 / 6).

[0193] Solution nine: 20, the focusing center line 016 of the dispersing structure A1 is not shifted relative to the first symmetry axis 017 of the subregion 031-1, i.e., H2-1 = 0. The focusing center line 016 of the dispersing structure A2 is shifted to the right by (1 / 3)h1 relative to the first symmetry axis 017 of the subregion 031-2, i.e., H2-2 = (1 / 3)h1. The focusing center line 016 of the dispersing structure A3 is shifted to the right by (2 / 3)h1 relative to the first symmetry axis 017 of the subregion 031-3, i.e., H2-3 = (2 / 3)h1. In the second pixel repeating unit group 014-2, the first pixel repeating unit row 013-1 is offset to the left by (-1 / 12)h1 relative to the first axis of symmetry 017, i.e., H1-1=-1 / 12 in this pixel repeating unit group. The second pixel repeating unit row 013-2 is offset to the left by (1 / 12)h1 relative to the first axis of symmetry 017, i.e., H1-2=1 / 12 in this pixel repeating unit group. In the remaining pixel repeating unit groups 014 (for example, the first pixel repeating unit group 014-1), the first pixel repeating unit row 013-1 has no offset with respect to the first axis of symmetry 017, i.e., H1-1 = 0, J1 = 0. The second pixel repeating unit row 013-2 is offset to the right by (1 / 6)h1 with respect to the first axis of symmetry 017, i.e., H1-2 = (1 / 6)h1, J2 = 1 / 6, and correspondingly, the second pixel repeating unit row 013-2 is offset to the right by (1 / 6)h1 with respect to the first pixel repeating unit row 013-1.

[0194] 1, 9, and 13 to 20, K / M is an integer. When K / M is an integer, the resolution of the display device becomes standard resolution, and in the case of standard resolution, there is no need to design a new display device layout method, and it is possible to avoid an increase in the difficulty of designing the display device while achieving a reduction in moiré fringes.

[0195] 1, 9, 13 to 20 all illustrate the case where M=K. In a specific implementation, when N / M is an integer and K / M is an integer, K may be greater than M. That is, one light-splitting structure corresponds to multiple pixel islands in one pixel repeat unit row. When K / M is an integer and K is greater than M, it is advantageous to increase the viewing angle of the main beam, which is useful for enabling viewing by multiple people.

[0196] For example, as shown in Figure 21, when 2M = K, that is, one dispersing structure A corresponds to two pixel islands S arranged along the row direction X in one pixel repeating unit row 013, M = 4, K = 8, and the width of the pixel island S in the row direction X is 181.8 μm. The focusing center line 016 of the dispersing structure A1 is not shifted relative to the first symmetry axis 017 of the subregion 031-1, i.e., H2-1 = 0. The focusing center line 016 of the dispersing structure A2 is shifted to the left by (1 / 4)h1 relative to the first symmetry axis 017 of the subregion 031-2, i.e., H2-2 = (-1 / 4)h1. The focusing center line 016 of the dispersing structure A3 is shifted to the right by (1 / 4)h1 relative to the first symmetry axis 017 of the subregion 031-3, i.e., H2-3 = (1 / 4)h1. The focusing center line 016 of the dispersing structure A4 is shifted to the right by (2 / 4)h1 relative to the first symmetry axis 017 of the subregion 031-4, i.e., H2-4 = (2 / 4)h1. The first distance between adjacent spectroscopic structures A1 and A2 is L1-1, the first distance between adjacent spectroscopic structures A2 and A3 is L1-2, the first distance between adjacent spectroscopic structures A3 and A4 is L1-3, and the first distance between adjacent spectroscopic structures A4 and A1 is L1-4. L1-1, L1-2, L1-3, and L1-4 are not equal, with L1-1 = 360.759375 μm, L1-2 = 369.28125 μm, L1-3 = 366.440625 μm, and L1-4 = 357.91875 μm. The sub-pixels in the second pixel repeating unit row 013-2 are shifted (-1 / 8)h1 to the left relative to the sub-pixels in the remaining second pixel repeating unit row 013.

[0197] Taking a liquid crystal lens as an example of a spectral structure (the refractive index of the liquid crystal is n-n = 1.81 - 1.51 = 0.3), if the liquid crystal lens aperture is designed to be 143.6 μm, the arch height to be 19.18 μm, and the placement height to be 700 μm, the light output angle spectrum of each subpixel will be as shown in Figures 22a, 22b, and 22c (Figure 22b is a partial enlargement of Figure 22a from the normal viewpoint, and Figure 22c is a partial enlargement of Figure 22a from the 20° viewpoint). When the human eye is viewing the center of the screen at a distance of 1000 mm from the screen, which is the normal viewpoint, there is -4th to +4th order crosstalk, as shown in Figure 22b, and the values ​​are 0.8%, 4.5%, 19.1%, 90.9%, 100%, 91.9%, 21.3%, 5%, and 0.9%. When viewing from the edge of the screen, the viewpoint is ±20°, and as shown in Figure 22c, there is -10 to +2 order crosstalk, with values ​​of 1.6%, 2.7%, 6.6%, 11%, 13.7%, 14.6%, 18%, 23%, 30.9%, 70%, 100%, 95.5%, and 58.5%. The crosstalk from the positive and negative first order onwards drops rapidly, and because the distance between the left and right eyes is 10 orders, when combined with a 3D eye placement diagram, a good 3D effect can be achieved, making viewing by multiple people possible.

[0198] 1, 9, 13 to 21, when N / M is an integer and K / M is an integer, the distance in the row direction X between any two adjacent dispersing structures A is greater than 0. That is, the two adjacent dispersing structures A are not closely spaced.

[0199] That is, compared to when two adjacent light-splitting structures A are closely spaced, the aperture ratio of the light-splitting structure in the display device provided by the embodiment of the present invention is smaller.

[0200] Taking a cylindrical lens as an example, the formula for calculating the main sphere viewing angle ω is as follows:

[0201]

number

[0202] Here, P is the width of one pixel island in the row direction, T is the height of the pillar lens, and k is the defocus amount of the pillar lens. The formula for the defocus amount is

number

[0203] As can be seen from the above formula for calculating the main circumferential viewing angle ω, when the dispersive structure is a pillar lens, the main circumferential viewing angle ω can be increased by reducing the aperture ratio of the pillar lens, making it easier to realize viewing by multiple people.

[0204] In some embodiments, as shown in FIGS. 1, 9, and 13 to 21, the light-splitting component 02 further includes a light-shielding portion 020 located between the light-splitting structures A.

[0205] In some embodiments, when the dispersive structures are not closely spaced, the widths of the dispersive structures in the row direction are equal.

[0206] 23, the pillar lens 010 includes a first resin layer 011 having a convex portion and a planarizing resin layer 012 located on the side of the first resin layer 011 away from the display panel 01. The refractive index of the planarizing resin layer 012 is smaller than the refractive index of the first resin layer 011.

[0207] In some embodiments, the display device further includes a partition medium layer 09 located between the light-splitting component 02 and the display panel 01, as shown in FIG.

[0208] In some embodiments, when the light-splitting structure is a geometric lens, the light-splitting component 02 includes a support portion 019 and a sealing portion 021 in addition to the geometric lens 018 and the light-shielding portion 020, as shown in FIGS.

[0209] In a specific implementation, the geometric lens 018 included in the spectroscopic component 02 may be a normal geometric lens as shown in FIG. 24, an inverted geometric lens as shown in FIG. 25, or a superposition of a normal geometric lens and an inverted geometric lens as shown in FIG. 26.

[0210] In a specific implementation, in the case of an upright geometric lens, the geometric lens can be directly mounted on the display panel 01 as a substrate, and the spectroscopic component 02 further includes a cover layer 027, as shown in Figure 24. If the geometric lens 018 included in the spectroscopic component 02 is an inverted geometric lens, the inverted geometric lens must be mounted on the substrate 022, as shown in Figures 25 and 26.

[0211] In a specific implementation, when the display panel is a liquid crystal display panel, the upper polarizer 023 is located on the side of the spectroscopic component 02 that is farther away from the display panel 01 .

[0212] In some embodiments, when the spectroscopic structure is a liquid crystal lens, the spectroscopic component 02 includes an upper substrate 024 and a lower substrate 025 arranged relative to each other, and a liquid crystal layer 026 located between the upper substrate 024 and the lower substrate 025, as shown in Figure 27. An upper polarizing piece 023 is located between the spectroscopic component 02 and the display panel 01.

[0213] In a specific implementation, the upper substrate includes a plurality of strip electrodes extending along the column direction, and the lower substrate includes a surface electrode provided on the entire surface.

[0214] Of course, in some embodiments, as shown in Fig. 28, the distance between any two adjacent dispersive structures A in the row direction X may be 0. In other words, the dispersive structures are closely spaced from each other.

[0215] When the spectral structures are closely spaced, the method of setting Vj corresponding to the M spectral structures in the spectral repeat unit and the method of setting Jj corresponding to the pixel repeat unit group are the same as in the embodiment where N / M is an integer. For example,

[0216] In a specific implementation, when the spectroscopic structures are closely spaced, N and M may be relatively prime.

[0217] In a specific implementation, if M dispersive structures correspond to K pixel islands, K / M is an integer.

[0218] Next, an example will be described using FIG. 28. The aperture ratio of the subpixel is 5 / 6, that is, M×M′=6, M=2, M′=3, N=9, and K / M=2. Vj corresponding to the two light-splitting structures A is selected from among -1 / 2, 0, and 1 / 2. In each pixel repeating unit group, Jj' corresponding to the pixel repeating unit row is selected from among -2 / 6, -1 / 6, 0, 1 / 6, and 2 / 6. The combination of Vj is (0, 1 / 2), and the combination of Jj' is (-1 / 6, 0, 1 / 6).

[0219] 28, the focusing center line 016 of the dispersing structure A1 is not shifted relative to the first symmetry axis 017 of the subregion 031-1, i.e., H2-1 = 0. The focusing center line 016 of the dispersing structure A2 is shifted to the right by (1 / 2)h1 relative to the first symmetry axis 017 of the subregion 031-2, i.e., H2-2 = (1 / 2)h1.

[0220] The first pixel repeat unit row 013-1 has no offset with respect to the first axis of symmetry 017, i.e., H1-1 = 0, J1 = 0. The second pixel repeat unit row 013-2 has an offset (1 / 6)h1 to the right with respect to the first axis of symmetry 017, i.e., H1-2 = (1 / 6)h1, J2 = 1 / 6. The third pixel repeat unit row 013-3 has an offset (1 / 6)h1 to the left with respect to the first axis of symmetry 017, i.e., H1-23 = -(1 / 6)h1, J3 = -1 / 6.

[0221] In a specific implementation, when the dispersive structures are closely spaced from one another, the widths of the dispersive structures in the row direction included in the dispersive component are all equal.

[0222] The display device provided by the embodiments of the present invention is any product or component with a display function, such as a mobile phone, a tablet, a television, a display, a notebook computer, a digital photo frame, a navigation device, etc. Other essential components of the display device should be understood by those skilled in the art, and will not be described in detail herein and should not be treated as limitations of the present invention.

[0223] In summary, in the display device provided by the embodiment of the present invention, the subpixels in at least two adjacent pixel repeat unit rows are staggered in the row direction, and / or at least some of the first distances are unequal. This prevents a single pixel repeat unit row from constituting a repeat unit of the pixel repeat unit row array, and / or prevents a single dispersing structure from constituting a repeat unit of the dispersing structure array. The staggered subpixels or dispersing structures can reduce the "dark zones" formed in space by the emitted light beams of N columns of subpixels after being dispersed by the M dispersing structures above them, compared to when the subpixels or dispersing structures are not staggered. This prevents the human eye from seeing the "dark zones" as it moves through the visible space, and reduces the problem of macroscopic Moiré fringes.

[0224] Although the best mode for carrying out the present invention has been described, those skilled in the art can make further changes and modifications to these modes once they understand the basic creative concept. Therefore, the appended claims should be interpreted as including the best mode for carrying out the invention and all changes and modifications that fall within the scope of the invention.

[0225] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Therefore, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and the equivalent technologies thereof, the present invention intends to include these modifications and variations.
