Abstract
Description
Display device Technical Field
[0001] The present disclosure relates to the field of display technology, and in particular to a display device. Background Art
[0002] With the continuous development of display technology, three-dimensional (3D) display technology is gaining increasing attention. 3D display technology can make displayed images appear three-dimensional and realistic. Its principle is to use the left and right eyes to 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-viewpoint 3D display and light field display, traditional sub-pixels are constructed into a pixel island structure, with each pixel island containing multiple sub-pixels. When the display information of multiple sub-pixels is different and a single eye enters multiple viewpoints, a normal light field display can be achieved. When the display information of multiple sub-pixels is different and a single eye enters a single viewpoint, an ultra-multi-viewpoint light field 3D display can be achieved.
[0003] However, existing 3D display products have the problem of moiré.

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. And in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0050] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.
[0051] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual scale and are only for the purpose of illustrating the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.
[0052] In the related art, as shown in FIG1 , a display device includes: a plurality of pixel islands S arranged at intervals along the row direction X and the column direction Y, and a plurality of cylindrical lenses Z; each pixel island S has a plurality of sub-pixels O8 arranged at intervals along the row direction X; M cylindrical lenses Z cover N columns of sub-pixels, which solves the macroscopic moiré problem, but creates a microscopic moiré problem. Within a unit with a period of M=5, the area corresponding to each cylindrical lens produces different brightness at different spatial viewing angles. At any viewing angle, the brightness of the five cylindrical lens areas seen is different. At one of the angles, the relative brightness distribution of the five areas seen is shown in FIG2 . The visual sensory effect is shown in FIG3 . For every five areas, there will be one area with the lowest brightness, which is called a dark area. Connecting the dark areas forms fine stripes, and because the fine stripes are relatively large in spacing (approximately 727.2μm), they are easily recognized by the human eye, resulting in the presence of microscopic moiré problems in the display device.
[0053] A display device provided in an embodiment of the present disclosure, as shown in FIG4 , includes:
[0054] Display panel 01, comprising: a plurality of pixel repeating units 04 arranged in an array along a row direction X and a column direction Y; each pixel repeating unit 04 comprises a plurality of pixel islands S arranged continuously in the column direction; each pixel island S comprises a plurality of sub-pixels 08 arranged at intervals along the row direction X; the plurality of pixel repeating units 04 comprises a plurality of pixel repeating unit rows 013 arranged along the column direction Y; the sub-pixels 08 in any two adjacent pixel repeating unit rows 013 are staggered in the row direction X;
[0055] The light-splitting component 02 is located on the display side of the display panel 01; the light-splitting component 02 includes a plurality of light-splitting repeating units 03 extending along the column direction Y and arranged continuously along the row direction X; the light-splitting repeating unit 03 includes M light-splitting structures A extending along the column direction Y and arranged continuously along the row direction X; each light-splitting repeating unit 03 corresponds to N columns of sub-pixels in a pixel repeating unit row; M and N are both integers greater than 1, and M and N are mutually prime.
[0056] It should be noted that the staggered arrangement of sub-pixels in two adjacent pixel repeating unit rows in the row direction means that the centers of the sub-pixels in two adjacent pixel repeating unit rows are not on a straight line in the column direction.
[0057] In the display device provided by the embodiment of the present disclosure, M spectroscopic structures correspond to N columns of sub-pixels in a row of pixel repeating units, and M and N are both integers greater than 1, that is, the spectroscopic structures and sub-pixels have a many-to-many correspondence. This can prevent the spectroscopic structure from being too small in the row direction, avoid increasing the difficulty of preparing the spectroscopic component, and avoid diffraction of the spectroscopic structure that is too small, which leads to an increase in the divergence angle of the light emitted by the sub-pixels and increased crosstalk between views, thereby affecting the display effect. In addition, the sub-pixels in at least some adjacent rows of pixel repeating units are staggered in the row direction, thereby disrupting the distribution of the dark areas corresponding to the spectroscopic repeating units, making the dark areas staggered, avoiding the formation of continuous fine stripes in the dark areas in the column direction, and alleviating the problem of microscopic moiré.
[0058] It should be noted that each light-splitting repeating unit corresponds to the N columns of sub-pixels in the pixel repeating unit row, which means that the orthographic projection of each light-splitting repeating unit on the plane where the display panel is located overlaps with the orthographic projection of the N columns of sub-pixels in the pixel repeating unit row on the plane where the display panel is located; since the sub-pixels in any two adjacent pixel repeating unit rows are staggered in the row direction, for example, for some pixel repeating unit rows, the orthographic projection of the light-splitting repeating unit on the plane where the display panel is located completely covers the orthographic projection of the N columns of sub-pixels in these pixel repeating unit rows on the plane where the display panel is located; for the remaining pixel repeating unit rows, the orthographic projection of the light-splitting repeating unit on the plane where the display panel is located does not completely cover the orthographic projection of the N columns of sub-pixels in these pixel repeating unit rows on the plane where the display panel is located, and for the sub-pixels located at the edge of the light-splitting repeating unit, the orthographic projection of the light-splitting repeating unit on the plane where the display panel is located only covers part of the orthographic projection of these sub-pixels on the plane where the display panel is located.
[0059] In some embodiments, as shown in FIG4 , the sub-pixels 08 in any two adjacent pixel repeating unit rows 013 are staggered in the row direction X. As a result, there are no adjacent dark regions in the column direction, preventing the formation of continuous fine stripes of dark regions in the column direction, effectively solving the problem of microscopic moiré.
[0060] It should be noted that the display device provided by the embodiments of the present disclosure can be applied to three-dimensional (3D) displays and can also realize switching between 3D and 2D displays. A pixel island can be used as a sub-pixel in a 2D display. Since a pixel island includes multiple sub-pixels, the same resolution as a 2D display can be maintained in 3D display mode. In combination with an eye-tracking system, multi-viewpoint display with a wide viewing angle can be realized. It can also realize 3D display with a higher pixel density (ppi), a larger amount of information, and lower color crosstalk between adjacent viewpoints.
[0061] In a specific implementation, the light splitting structure is used to control the light emission angle of each sub-pixel so that it emits light in a direction.
[0062] In a specific implementation, the display panel can be one of 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, and a mini light emitting diode (mini LED) display panel.
[0063] In some embodiments, as shown in FIG4 , a pixel repeating unit 04 includes three pixel islands S arranged continuously in the column direction Y;
[0064] In a pixel repeating unit 04 , the sub-pixels 08 in the same pixel island S display the same color, while the sub-pixels 08 in different pixel islands S display different colors.
[0065] In some embodiments, as shown in Figure 4, a pixel repetition 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 sub-pixels R, the second pixel island 06 includes multiple green sub-pixels G, and the third pixel island 07 includes multiple blue sub-pixels B.
[0066] In some embodiments, as shown in FIG. 4 , the sub-pixels 08 in a row of pixel islands S display the same color.
[0067] In some embodiments, as shown in Figure 4, multiple pixel repeating unit rows 013 are divided into multiple pixel repeating unit groups 014, each pixel repeating unit group 014 includes M pixel repeating unit rows 013; in each pixel repeating unit group 014, the sub-pixels 08 in any two adjacent pixel repeating unit rows 013 are staggered in the row direction X; each pixel repeating unit group 014 is divided into sub-units 015 corresponding one-to-one to the light-splitting repeating units 03; that is, the part of each pixel repeating unit group 014 corresponding to the M light-splitting structures A is regarded as a sub-unit 015.
[0068] It should be noted that in FIG. 4 , M=5, that is, the pixel repeating unit group 014 includes five pixel repeating unit rows 013 ; FIG. 4 shows only one subunit 015 , that is, only the portion of the pixel repeating unit group 014 corresponding to the five light splitting structures A.
[0069] In some embodiments, as shown in Figure 4, in the sub-unit, the ratio of the misalignment vector Hj of the c-th sub-pixel 08 in the j-th pixel repeating unit row 013 and the c-th sub-pixel 08 in the 1st pixel repeating unit row 013 in the row direction X to the width h1 of the sub-pixel in the row direction X is Jj=±E / M, where c is an integer greater than or equal to 1 and less than or equal to N, j is an integer greater than 1 and less than or equal to M, and E is an integer greater than or equal to 1 and not equal to M and not equal to an integer multiple of M.
[0070] That is, in the embodiment of the present disclosure, each sub-pixel in the second pixel repeating unit row to each sub-pixel in the Mth pixel repeating unit row in each sub-unit is staggered by Jj×h1 relative to the sub-pixel in the first pixel repeating unit row.
[0071] It should be noted that, taking the row direction X shown in Figure 4 as an example, the row direction X is the left-right extending direction in the figure. The sub-pixel 08 in the j-th pixel repeating unit row 013 may be offset to the left relative to the sub-pixel 08 in the first pixel repeating unit row 013. In this case, Hj is positive, and Jj = +E / M; or the sub-pixel 08 in the j-th pixel repeating unit row 013 may be offset to the right relative to the sub-pixel 08 in the first pixel repeating unit row 013. In this case, Hj is negative, and Jj = -E / M.
[0072] In some embodiments, in each pixel repeating unit group, the sub-pixels in different sub-units of the same pixel repeating unit row have the same offset vector. That is, in each pixel repeating unit group, for M pixel repeating unit rows 013, the ratio of the offset vector Hj in the row direction between the sub-pixels in the jth pixel repeating unit row and the sub-pixels in the first pixel repeating unit row to the width h1 of the sub-pixels in the row direction X is Jj = ±E / M.
[0073] It should be noted that the relative brightness distribution of the area of a sub-unit corresponding to the M splitting structures can be divided into M*M brightness areas. For a sub-unit, when each sub-pixel in the 2nd pixel repeating unit row to each sub-pixel in the Mth pixel repeating unit row is staggered relative to the sub-pixel in the 1st pixel repeating unit row, the dark area with the lowest brightness in the brightness area corresponding to the 2nd to Mth pixel repeating unit rows is staggered relative to the dark area corresponding to the 1st pixel repeating unit row, thereby disrupting the distribution of the dark area of the area corresponding to the sub-unit, so that the dark area is staggered; and because the display panel includes multiple pixel repeating unit groups, the pixel repeating unit group includes multiple sub-units, that is, the sub-unit serves as the smallest unit for disrupting the distribution of the dark area. Since the dark area distribution of each sub-unit is disrupted in the column direction, the entire display device can avoid the continuous formation of fine stripes in the dark area in the column direction, solving the problem of microscopic moiré.
[0074] In a specific implementation, when M=5, Jj can be: -11 / 5, -6 / 5, -4 / 5, -3 / 5, -2 / 5, -1 / 5, 1 / 5, 2 / 5, 3 / 5, 4 / 5, 6 / 5, 11 / 5, etc.
[0075] It should be noted that when the difference between the two Jj is M or an integer multiple of M, for example, Jj is -6 / 5 and -1 / 5 respectively, the number of brightness areas between the dark area of this row and the dark area of the first row when Jj is -6 / 5 is the same as the number of brightness areas between the dark area of this row and the dark area of the first row when Jj is -1 / 5.
[0076] In some embodiments, in a subunit, in the 2nd to Mth pixel repeating unit rows, the Jj corresponding to any two pixel repeating unit rows are not equal, and the absolute value of the difference between the Jj corresponding to any two pixel repeating unit rows is not an integer greater than or equal to 1. In this way, within a pixel repeating unit group, no dark areas are located in the same column in the column direction, thereby increasing the distance between two dark areas arranged in the column direction and preventing the appearance of thin lines in the column direction that are easily perceived by the human eye.
[0077] In some embodiments, in the sub-unit, the ratio ΔJ of the offset vector of the c-th sub-pixel in the row direction to the width of the sub-pixel in the row direction in at least some adjacent two pixel repeating unit rows is not equal to ± or Here, C is an integer greater than 0. This allows the dark areas in two adjacent pixel repeating unit rows to be separated by at least one bright area, avoiding continuous dark areas. This makes it more difficult for the human eye to detect the presence of thin lines extending in an oblique direction, effectively solving the problem of microscopic moiré.
[0078] In some embodiments, E is an integer greater than or equal to 1 and less than or equal to M-1. That is, the sub-pixel offset vector does not exceed the width of a sub-pixel in the row direction X. This can disrupt the distribution of dark areas in the area corresponding to the sub-unit while preventing excessive sub-pixel offset distances, thereby facilitating the rational use of display panel space.
[0079] It should be noted that, when M=5 and E is an integer greater than or equal to 1 and less than or equal to M-1, Jj can be one of the following: -4 / 5, -3 / 5, -2 / 5, -1 / 5, 1 / 5, 2 / 5, 3 / 5, 4 / 5. When Jj is -4 / 5, the dark area corresponding to this row is displaced by 4 brightness areas to the right relative to the dark area corresponding to the first row (the dark area corresponding to this row is separated from the dark area corresponding to the first row by 3 brightness areas); when Jj is -3 / 5, the dark area corresponding to this row is displaced by 3 brightness areas to the right relative to the dark area corresponding to the first row (the dark area corresponding to this row is separated from the dark area corresponding to the first row by 2 brightness areas); when Jj is -2 / 5, the dark area corresponding to this row is displaced by 2 brightness areas to the right relative to the dark area corresponding to the first row (the dark area corresponding to this row is separated from the dark area corresponding to the first row by 1 brightness area); when Jj is -1 / 5, the dark area corresponding to this row is displaced by 1 brightness area to the right relative to the dark area corresponding to the first row (the dark area corresponding to this row is separated from the dark area corresponding to the first row by 0 brightness areas). ); when Jj is 1 / 5, the dark area corresponding to this row is displaced to the left by 1 brightness area relative to the dark area corresponding to the first row (the dark area corresponding to this row and the dark area corresponding to the first row are separated by 0 brightness areas); when Jj is 2 / 5, the dark area corresponding to this row is displaced to the left by 2 brightness areas relative to the dark area corresponding to the first row (the dark area corresponding to this row and the dark area corresponding to the first row are separated by 1 brightness area); when Jj is 3 / 5, the dark area corresponding to this row is displaced to the left by 3 brightness areas relative to the dark area corresponding to the first row (the dark area corresponding to this row and the dark area corresponding to the first row are separated by 2 brightness areas); when Jj is 4 / 5, the dark area corresponding to this row is displaced to the left by 4 brightness areas relative to the dark area corresponding to the first row (the dark area corresponding to this row and the dark area corresponding to the first row are separated by 3 brightness areas).
[0080] In some embodiments, when M is 5, J2 is -2 / 5 or 3 / 5, J3 is 1 / 5 or -4 / 5, J4 is -1 / 5 or 4 / 5, and J5 is 2 / 5 or -3 / 5.
[0081] In a specific implementation, for example, J2 is -2 / 5, J3 is 1 / 5, J4 is -1 / 5, and J5 is 2 / 5. Correspondingly, as shown in FIG4 , H2 = (-2 / 5)h1, H3 = (1 / 5)h1, H4 = (-1 / 5)h1, and H5 = (2 / 5)h1.
[0082] Of course, in specific implementation, J2 may be 3 / 5, J3 may be -4 / 5, J4 may be 4 / 5, and J5 may be -3 / 5.
[0083] In a specific implementation, when M = 5, J2 is -2 / 5, J3 is 1 / 5, J4 is -1 / 5, and J5 is 2 / 5, the relative brightness distribution of the area of a subunit corresponding to the five splitting structures is shown in Figure 5. The relative brightness distribution of the area of a subunit corresponding to the five splitting structures can be divided into 5*5 brightness areas; among them, the area corresponding to the relative brightness of 55.6% is the dark area. The visual perception effect of the area of a subunit shown in Figure 5 is shown in Figure 6. The dark areas in different rows are no longer in the same column, that is, the dark areas in different rows are staggered. The visual perception effect of the area of multiple subunits is shown in Figure 7.
[0084] It should be noted that although thin dark lines are formed when the dark areas shown in FIG7 are connected, they extend in a direction with an angle greater than 0 with the row and column directions (hereinafter referred to as an oblique direction). Furthermore, the spacing between the dark lines extending in the oblique direction is 391.6 microns, which is much smaller than the spacing between the dark lines extending in the column direction (727.2 microns) in the related art. This 391.6-micron spacing is not easily noticeable at a viewing distance of 300 mm. Typically, users view displays from a distance of 630 mm. At this viewing distance, the presence of thin lines extending in the oblique direction is less noticeable to the human eye, effectively addressing the microscopic moiré problem.
[0085] In some embodiments, when E is an integer greater than or equal to 1 and less than or equal to M-1, in the subunit, in the 2nd to Mth pixel repeating unit rows, the Jj corresponding to any two pixel repeating unit rows are not equal, and when the Jj corresponding to two pixel repeating unit rows is one + and the other -, the sum of the absolute values of the Jj corresponding to the two pixel repeating unit rows is not equal to 1. In this way, within a pixel repeating unit group, no dark areas are located in the same column in the column direction, thereby increasing the distance between two dark areas arranged in the column direction and preventing the appearance of thin lines in the column direction that are easily perceived by the human eye.
[0086] In some embodiments, as shown in Figures 5 and 6 , within the brightness region corresponding to a subunit, the center lines connecting multiple dark regions are not aligned. That is, within the brightness region corresponding to a subunit, multiple dark regions are not arranged sequentially along a direction with an angle greater than 0 with the row or column directions (hereinafter referred to as an oblique direction). Instead, the multiple dark regions are distributed along multiple straight lines extending along the oblique direction. Thus, compared to a situation where the center lines connecting multiple dark regions are aligned, as shown in Figure 7 , the distance between the thin dark region lines in the entire display device is smaller, making it more difficult for the human eye to detect the presence of thin lines extending in the oblique direction, effectively solving the problem of microscopic moiré.
[0087] In some embodiments, when E is an integer greater than or equal to 1 and less than or equal to M-1, in the subunit, the ratio ΔJ of the offset vector of the c-th subpixel in the row direction to the width of the subpixel in the row direction in at least some adjacent rows of pixel repeating units is not equal to ±1 / M or ±(M-1) / M. This allows the dark areas in two adjacent rows of pixel repeating units to be separated by at least one bright area, preventing continuous dark areas. This makes it easier for the human eye to detect the presence of thin lines extending in an oblique direction, effectively solving the problem of microscopic moiré.
[0088] In some embodiments, each light-splitting repeating unit corresponds to K columns of pixel islands in a row of pixel repeating units, where K is an integer greater than 1.
[0089] In the display device provided by the embodiments of the present disclosure, each light-splitting repeating unit corresponds to K columns of pixel islands in a row of pixel repeating units. That is, M light-splitting structures correspond to K columns of pixel islands in a row of pixel repeating units, where M and K are both integers greater than 1, resulting in a many-to-many correspondence between light-splitting structures and pixel island columns. This prevents the light-splitting structures from being too small in the row direction, which increases the difficulty of manufacturing the light-splitting components. It also prevents diffraction from undersized light-splitting structures, which can lead to an increased divergence angle of light emitted from sub-pixels and increased crosstalk between views, thus affecting the display quality.
[0090] In some embodiments, N / K is an integer, that is, the N columns of sub-pixels in the pixel repeating unit row corresponding to the M light-splitting units can be evenly divided into multiple columns of pixel islands.
[0091] In a specific implementation, as shown in FIG4 , each pixel island S includes n sub-pixels 08 arranged at intervals along the row direction X; wherein n is an integer greater than 1; each light-splitting repeating unit corresponds to K columns of pixel islands in a pixel repeating unit row, N=K*n; K is an integer greater than 1, and M and K are mutually prime.
[0092] Alternatively, in some embodiments, N and K are relatively prime, that is, the N columns of sub-pixels in the pixel repeating unit row corresponding to the M light-splitting units cannot be evenly divided into multiple columns of pixel islands.
[0093] In a specific implementation, even if the N columns of sub-pixels in the pixel repeating unit row corresponding to the M splitting units cannot be evenly divided into multiple columns of pixel islands, the splitting units and the pixel islands are still in a many-to-many relationship, which can still prevent the splitting structure from being too small in the row direction, avoid increasing the difficulty of preparing the splitting components, and avoid diffraction of the splitting structure that is too small, resulting in an increase in the sub-pixel light divergence angle and increased crosstalk between views, which affects the display effect.
[0094] In some embodiments, in the horizontal direction, the width of the M light-splitting structures is equal to the width of N columns of sub-pixels in a row of a pixel repeating unit.
[0095] In some embodiments, the light-emitting areas of N columns of sub-pixels in a pixel repeating unit row form a continuous light-emitting area in space after the light is split by M light-splitting structures.
[0096] In the display device provided by the embodiment of the present disclosure, M light-splitting structures correspond to N columns of sub-pixels, and the luminous areas of each sub-pixel in the N columns of sub-pixels are staggered in space. Since the size of the light-splitting structure in the row direction is relatively small, for the N columns of sub-pixels corresponding to the M light-splitting structures, the human eye cannot distinguish which specific light-splitting structure the light is emitted from. Therefore, to the human eye, the light emitted from the N columns of sub-pixels after being split by the M light-splitting structures above them forms a continuous luminous area in space, and the human eye will not see a "black area" when moving in the visible space.
[0097] In some embodiments, the sub-pixel includes a sub-pixel opening area; in the row direction, the ratio of the total width of the n sub-pixel opening areas to the width of the pixel island is greater than or equal to 0.9 / M and less than or equal to 1. That is, the aperture ratio of the sub-pixel in the pixel island is greater than or equal to 0.9 / M and less than or equal to 1.
[0098] In some embodiments, in the row direction, the light-emitting areas of the N columns of sub-pixels in a row of the pixel repeating unit are spatially complementary.
[0099] In some embodiments, in the row direction, the ratio of the width of the subpixel opening area 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. This arrangement allows the subpixels below each light-splitting repeating unit to be arranged in a staggered and complementary manner relative to the corresponding light-splitting structure, so that the light-emitting areas of N columns of subpixels are spatially complementary and spliced, that is, the optical paths of each viewpoint are closely connected, which can reduce macroscopic moiré patterns and improve display effects.
[0100] In some embodiments, in the row direction, the light-emitting areas of the N columns of sub-pixels in a row of the pixel repeating unit are spatially overlapped.
[0101] In some embodiments, in the row direction, the light-emitting areas of the N columns of sub-pixels in a row of the pixel repeating unit are spatially uniformly overlapped.
[0102] In some embodiments, in the row direction, the ratio of the width of the sub-pixel opening area to the width of the pixel island is i / M, where i is an integer greater than 1 and less than or equal to M-1.
[0103] It should be noted that in the display device provided by the embodiments of the present disclosure, M light-splitting structures correspond to N columns of sub-pixels in a row of pixel repeating units, and M light-splitting structures correspond to K pixel islands in a row of pixel repeating units, that is, there is a many-to-many relationship between the sub-pixels and the light-splitting structures, and at the same time, there is a many-to-many relationship between the pixel islands and the light-splitting structures. When the width of the M light-splitting structures in the row direction is equal to the width of the N columns of sub-pixels in the row of pixel repeating units, even if the number of light-splitting structures is increased, the size of the light-splitting structures in the row direction will not be too small to make them difficult to manufacture. Moreover, when the aperture ratio of the sub-pixel is i / M, where i is an integer greater than 1 and less than or equal to M-1, compared to the case where there is a one-to-many relationship between the pixel islands and the light-splitting structures, the sub-pixel aperture ratio can be increased when the number of light-splitting structures is the same.
[0104] In a specific implementation, when each light-splitting repeating unit corresponds to K columns of pixel islands and N=K*n, the width of N columns of sub-pixels is the width of K columns of pixel islands. In the horizontal direction, the width of M light-splitting structures is equal to the width of K columns of pixel islands.
[0105] In a specific implementation, when each splitting repetition unit corresponds to K columns of pixel islands and N=K*n, the luminous areas of each sub-pixel in the K pixel islands are spatially staggered, so that the light emitted by each sub-pixel in the K pixel islands forms a continuous luminous area after being split by M splitting structures.
[0106] It should be noted that the space in “the light-emitting areas of the sub-pixels in the K pixel islands are spatially staggered” refers to the visible space of the display device.
[0107] In the display device provided by the embodiment of the present disclosure, there are M light-splitting structures corresponding to K pixel islands, and the luminous areas of each sub-pixel in the K pixel islands are staggered in space. Since the size of the light-splitting structure in the row direction is relatively small, for the K pixel islands covered by the M light-splitting structures, the human eye cannot distinguish which specific light-splitting structure the light is emitted from. Therefore, to the human eye, the light emitted from the K pixel islands after being split by the M light-splitting structures above them forms a continuous luminous area in space, and the human eye will not see a "black area" when moving in the visible space.
[0108] It should be noted that the viewing angle includes the main lobe viewing angle and the side lobe viewing angle. The main lobe viewing angle refers to the viewing angle formed in space after the light emitted by the sub-pixel passes through the spectroscopic structure directly above it. The side lobe viewing angle refers to the viewing angle formed in space after the light emitted by the sub-pixel passes through the spectroscopic structure next to the spectroscopic structure directly above it. For example, the light passing through the first spectroscopic structure adjacent to the spectroscopic structure directly above is the first-level side lobe viewing angle, and the light passing through the second spectroscopic structure adjacent to the spectroscopic structure directly above is the second-level side lobe viewing angle, and so on.
[0109] To better understand this solution, we will take the main lobe perspective as an example, and take the example where each splitting repetition unit corresponds to K columns of pixel islands and N=K*n, to illustrate that the luminous areas of each sub-pixel in the K pixel islands are staggered in space, and the luminous areas of each sub-pixel in the K pixel islands are split by M splitting structures to form a continuous luminous area in space.
[0110] In a specific implementation, among the M light-splitting structures arranged in the row direction, the difference between the viewpoints of two adjacent sub-pixels in the multiple sub-pixels corresponding to each light-splitting structure is M.
[0111] In some embodiments, K is 4, M is 5, n is 4, and the sub-pixel aperture ratio is 1 / 5. Light path diagrams for K columns of pixel islands are shown in Figures 8 and 9. The five light-splitting structures correspond to four columns of pixel islands in a row of a pixel repeating unit. Each row of the four columns of pixel islands includes 16 sub-pixels, labeled 1st sub-pixel 1 to 16th sub-pixel 16. The sequence number of each sub-pixel 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. The first pixel island S1 includes: the first sub-pixel 1, the sixth sub-pixel 6, the eleventh sub-pixel 11 and the sixteenth sub-pixel 16; the second pixel island S2 includes: the fifth sub-pixel 5, the tenth sub-pixel 10, the fifteenth sub-pixel 15 and the fourth sub-pixel 4; the third pixel island S3 includes: the ninth sub-pixel 9, the fourteenth sub-pixel 14, the third sub-pixel 3 and the eighth sub-pixel 8; the fourth pixel island S4 includes: the thirteenth sub-pixel 13, the second sub-pixel 2, the seventh sub-pixel 7 and the twelfth sub-pixel 12. The light-splitting structures corresponding to the 16 sub-pixels are respectively marked as the first light-splitting structure A1 to the fifth light-splitting structure A5; as shown in Figure 8, the first light-splitting structure A1 covers the first sub-pixel 1, the sixth sub-pixel 6, the eleventh sub-pixel 11 and the sixteenth sub-pixel 16, the second light-splitting structure A2 covers the fifth sub-pixel 5, the tenth sub-pixel 10 and the fifteenth sub-pixel 15, the third light-splitting structure A3 covers the fourth sub-pixel 4, the ninth sub-pixel 9 and the fourteenth sub-pixel 14, the fourth light-splitting structure A4 covers the third sub-pixel 3, the eighth sub-pixel 8 and the thirteenth sub-pixel 13, and the fifth light-splitting structure A5 covers the second sub-pixel 2, the seventh sub-pixel 7 and the twelfth sub-pixel 12. As shown in Figure 8, the relative positional relationship between each sub-pixel and the light-splitting structure within the four pixel islands does not constitute a repeating unit. If the sub-pixels are spliced in viewpoint order, while maintaining the relative position of each sub-pixel and the light-splitting structure unchanged, as shown in Figure 9, after the sub-pixels corresponding to each light-splitting structure are spliced, the sub-pixels are positioned complementary, that is, the gap between each sub-pixel is zero, forming a staggered complementary arrangement with the relative positional relationship of the light-splitting structure. Accordingly, the luminous areas of each sub-pixel within the four pixel islands are spatially staggered, and the luminous areas of each sub-pixel within the four pixel islands also form a staggered complementary arrangement in space. As shown in Figure 8. Since there are gaps between the first sub-pixel 1 to the fifth sub-pixel 5, the light emitted by adjacent sub-pixels corresponding to the same spectroscopic structure has discontinuous light output angles in space after passing through the same spectroscopic structure A. However, since the relative positions of each sub-pixel in the four pixel islands and the five spectroscopic structures A are staggered, the light-emitting areas of each sub-pixel in the four pixel islands are staggered in space, and therefore the light output angles of each spectroscopic structure A are also staggered and complementary.Since the size of the spectroscopic structure A is very small, the human eye cannot distinguish which spectroscopic structure A the light is emitted from. Therefore, as shown in Figure 9, the light emitted by the 16 sub-pixels in the four pixel islands after being split by the five spectroscopic structures forms a continuous luminous area in space. The human eye will not see a "black area" when moving in space.
[0112] The continuity of the sidelobe viewing angle is similar to the continuity of the mainlobe viewing angle mentioned above. The two discontinuous first-level sidelobe viewing angles of K pixel islands passing through adjacent splitting structures can complement each other to form a continuous first-level sidelobe viewing angle. In addition, the width of the M splitting structures in the horizontal direction is equal to the width of the K columns of pixel islands in a pixel repeating unit row. Therefore, the mainlobe viewing angle boundary is parallel to the sidelobe viewing angle boundary. Since the human eye cannot distinguish the distance between the mainlobe viewing angle boundary and the sidelobe viewing angle boundary, the mainlobe viewing angle and the sidelobe viewing angle are also observed to be continuous. By the same token, the first-level sidelobe viewing angle is also continuous with the second-level sidelobe viewing angle, the second-level sidelobe viewing angle is also continuous with the third-level sidelobe viewing angle, and so on. In this way, a continuous viewing angle is obtained.
[0113] In some embodiments, K is 4, M is 5, n is 4, and the subpixel aperture ratio is 4 / 5. The optical path diagrams of the K pixel islands in a pixel unit row are shown in Figures 10 and 11. The four pixel islands corresponding to the five light-splitting structures include 16 subpixels, labeled as the first subpixel 1 to the sixteenth subpixel 16. The sequence 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. The first pixel island S1 includes the first subpixel 1, the sixth subpixel 6, the eleventh subpixel 11, and the sixteenth subpixel 16; the second pixel island S2 includes the fifth subpixel 5, the tenth subpixel 10, the fifteenth subpixel 15, and the fourth subpixel 4; the third pixel island S3 includes the ninth subpixel 9, the fourteenth subpixel 14, the third subpixel 3, and the eighth subpixel 8; and the fourth pixel island S4 includes the thirteenth subpixel 13, the second subpixel 2, the seventh subpixel 7, and the twelfth subpixel 12. The light-splitting structures corresponding to the 16 sub-pixels are respectively marked as the first light-splitting structure A1 to the fifth light-splitting structure A5; as shown in Figure 10, the first light-splitting structure A1 covers the first sub-pixel 1, the sixth sub-pixel 6, the eleventh sub-pixel 11 and part of the sixteenth sub-pixel 16, the second light-splitting structure A2 covers part of the sixteenth sub-pixel 16, the fifth sub-pixel 5, the tenth sub-pixel 10 and part of the fifteenth sub-pixel 15, the third light-splitting structure A3 covers part of the fifteenth sub-pixel 15, the fourth sub-pixel 4, the ninth sub-pixel 9 and part of the fourteenth sub-pixel 14, the fourth light-splitting structure A4 covers part of the fourteenth sub-pixel 14, the third sub-pixel 3, the eighth sub-pixel 8 and the thirteenth sub-pixel 13, and the fifth light-splitting structure A5 covers the second sub-pixel 2, the seventh sub-pixel 7 and the twelfth sub-pixel 12. As shown in Figure 10, the relative positional relationship between each sub-pixel and the light-splitting structure within the four pixel islands does not constitute a repeating unit. If the sub-pixels are spliced in viewpoint order, while maintaining the relative position of each sub-pixel and the light-splitting structure unchanged, as shown in Figure 11, after the sub-pixels corresponding to the light-splitting structures are spliced, the sub-pixels overlap, forming a staggered and overlapping arrangement with the relative positional relationship of the light-splitting structure. Accordingly, the luminous areas of each sub-pixel within the four pixel islands are spatially staggered, and the luminous areas of each sub-pixel within the four pixel islands also form a staggered and complementary arrangement in space. As shown in Figure 10. Since there is a gap between the first sub-pixel 1 to the fifth sub-pixel 5, the light emitted by adjacent sub-pixels corresponding to the same spectroscopic structure is discontinuous in the spatial output angle after passing through the same spectroscopic structure A. However, since the relative positions of each sub-pixel in the four pixel islands and the five spectroscopic structures A are staggered and evenly overlapped, the light-emitting areas of each sub-pixel in the four pixel islands are evenly overlapped in space, so the light-emitting angles of each spectroscopic structure A are also staggered and evenly overlapped.Since the size of the spectroscopic structure A is very small, the human eye cannot distinguish which spectroscopic structure A the light is emitted from. Therefore, as shown in Figure 11, the light emitted by the 16 sub-pixels in the four pixel islands after being split by the five spectroscopic structures forms a continuous luminous area in space. The human eye will not see a "black area" when moving in space.
[0114] In some embodiments, as shown in Figure 10, in the row direction, the ratio of the total width n×h1 of the n sub-pixel opening areas to the width h2 of the pixel island is i / M, where i is an integer greater than 1 and less than or equal to M-1. That is, the aperture ratio of the sub-pixels in the pixel island is i / M. This arrangement allows the sub-pixels beneath each light-splitting repeating unit to be arranged in a uniformly staggered and overlapping arrangement relative to the corresponding light-splitting structure. This ensures that the light-emitting areas of the sub-pixels within the K pixel islands overlap uniformly in space, meaning that the light paths of each viewpoint overlap uniformly. This also eliminates macroscopic moiré patterns and improves display quality.
[0115] In a specific implementation, when the light-emitting areas of the sub-pixels in K pixel islands overlap uniformly in space, the ratio of the area of the overlapping region of the light-emitting areas of two adjacent sub-pixels to the area of the light-emitting area of one sub-pixel is (i-1) / i. The ratio of the area of the overlapping region of the light-emitting areas of two adjacent sub-pixels to the area of one sub-pixel is (i-1) / M.
[0116] It should be noted that when the ratio of the total width n×h1 of the n sub-pixel opening areas in the row direction to the width h2 of the pixel island is 1 / M, that is, when i=1, the light-emitting areas of each sub-pixel do not overlap in space. When i=2, the ratio of the area of the overlapping area of the light-emitting areas of two adjacent sub-pixels to the area of the light-emitting area of one sub-pixel is 1 / 2, and the ratio of the area of the overlapping area of the light-emitting areas of two adjacent sub-pixels to the area of one sub-pixel is 1 / M; when i=3, the ratio of the area of the overlapping area of the light-emitting areas of two adjacent sub-pixels to the area of the light-emitting area of one sub-pixel is 2 / 3, and the ratio of the area of the overlapping area of the light-emitting areas of two adjacent sub-pixels to the area of one sub-pixel is 2 / M; when i=4, the ratio of the area of the overlapping area of the light-emitting areas of two adjacent sub-pixels to the area of one sub-pixel is 2 / 3. The ratio of the area of the overlapping area of the sub-pixel light-emitting areas to the area of the light-emitting area of one of the sub-pixels is 3 / 4, and the ratio of the area of the overlapping area of the light-emitting areas of two adjacent sub-pixels to the area of one of the sub-pixels is 3 / M; when i=M-1, the ratio of the area of the overlapping area of the light-emitting areas of two adjacent sub-pixels to the area of the light-emitting area of one of the sub-pixels is (M-2) / (M-1), and the ratio of the area of the overlapping area of the light-emitting areas of two adjacent sub-pixels to the area of one of the sub-pixels is (M-2) / M; and so on, no further details are given.
[0117] It should be noted that FIG10 illustrates an example in which the ratio of the total width of the n sub-pixel opening areas to the width of the pixel island in the row direction is (M-1) / M, or 4 / 5. This means that the aperture ratio of the sub-pixels in the pixel island in FIG4 is 4 / 5. When the aperture ratio of the sub-pixels in the pixel island is (M-1) / M, the aperture ratio of the sub-pixels can be maximized while ensuring uniform spatial overlap between the light-emitting areas of the sub-pixels in the K pixel islands in the row direction. Of course, in a specific implementation, the aperture ratio of the sub-pixels in the pixel island can also be 2 / M, 3 / M, etc.
[0118] In some embodiments, as shown in FIG12 , the display device further includes:
[0119] The spacer dielectric layer 09 is located between the light splitting component 02 and the display panel 01 .
[0120] In some embodiments, the light splitting structure is a cylindrical lens.
[0121] In some embodiments, as shown in FIG12 , the cylindrical lens 010 includes a first resin layer 011 having a protrusion, and a planarization resin layer 012 located on a side of the first resin layer 011 away from the display panel 01 ; the refractive index of the planarization resin layer 012 is smaller than that of the first resin layer 011 .
[0122] Alternatively, in some embodiments, the cylindrical lens is a liquid crystal lens.
[0123] Of course, in specific implementation, the light splitting structure can also be a structural device such as a geometric lens, a diffraction lens, a liquid lens, etc. that can control the light emitting direction of the sub-pixel.
[0124] In some embodiments, the display device further comprises:
[0125] Eye tracking system, used to determine the position of the user's eyes in real time.
[0126] The display device provided in the embodiments of the present disclosure may be any product or component with a display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, navigation system, smartwatch, fitness tracker, personal digital assistant, or the like. Other essential components of the display device are well understood by those skilled in the art and are not detailed here, nor should they be construed as limitations of the present disclosure.
[0127] In summary, in the display device provided by the embodiment of the present disclosure, M spectroscopic structures correspond to N columns of sub-pixels in a row of pixel repeating units, and both M and N are integers greater than 1, that is, the spectroscopic structures and sub-pixels have a many-to-many correspondence. This can prevent the spectroscopic structure from being too small in the row direction, avoid increasing the difficulty of preparing the spectroscopic component, and avoid the diffraction of the spectroscopic structure that is too small, which leads to an increase in the divergence angle of the sub-pixel light output, an increase in crosstalk between views, and an impact on the display effect. Moreover, the sub-pixels in at least some adjacent rows of pixel repeating units are staggered in the row direction, thereby disrupting the distribution of the dark areas corresponding to the spectroscopic repeating units, making the dark areas staggered, avoiding the continuous formation of fine stripes in the dark areas in the column direction, and effectively alleviating the problem of microscopic moiré.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
[0129] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if such changes and modifications of the embodiments of the present invention fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
