Description

[Technical Field]

[0001] The present application relates to the field of display technology, and more particularly to display devices. [Background technology]

[0002] With the continuous development of display technology, three-dimensional (3D) display technology has attracted increasing attention. 3D display technology can create a three-dimensional, realistic display. Its principle is that a person's left and right eyes receive left and right 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 optical field display, the traditional subpixel is structured as a pixel island. Each pixel island contains multiple subpixels. The display information of the multiple subpixels is different, and when a single eye views multiple viewpoints, a conventional optical field display can be realized. When the display information of the multiple subpixels is different, a single eye views a single viewpoint, a super-multi-view optical field 3D display can be realized.

[0003] However, prior art 3D display products suffer from Moire fringes.

[0023] In some embodiments, the light-emitting regions of the N column sub-pixels in a pixel overlap unit row in the row direction are spatially complementary to each other.

[0024] In some embodiments, the ratio of the width of the sub-pixel aperture region to the width of the pixel island in the row direction is 1 / M.

[0025] In some embodiments, there is spatial overlap between the light emitting areas of the N column sub-pixels in a pixel overlap unit row in the row direction.

[0026] In some embodiments, there is uniform spatial overlap between the light-emitting areas of the N column sub-pixels in the row direction.

[0027] In some embodiments, the ratio of the width of the sub-pixel aperture region to the width of the pixel island in the row direction is i / M, where i is an integer greater than 1 and less than or equal to M-1.

[0034] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present application in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Furthermore, the embodiments and features of the embodiments of the present application can be combined with each other if there is no contradiction. All other embodiments that can be obtained by those skilled in the art based on the described embodiments of the present application without exerting their creative efforts are within the scope of the claims of the present application.

[0035] Unless otherwise defined, technical or scientific terms used in this application should be understood to have the common meaning understood by those skilled in the art. The terms "first," "second," and similar terms used in this application do not denote any order, quantity, or importance, but are merely used to distinguish different structural parts. Similar terms such as "comprise" mean that the member or component before the term includes the member or component listed after the term and equivalents thereof, but do not exclude other members or components. Similar terms such as "connect" are not limited to physical or mechanical connections, but may also include electrical connections, whether direct or indirect.

[0036] In addition, the dimensions and shapes of the figures in the drawings do not reflect the true scale and are intended only to roughly explain the present application. In addition, the same or similar reference numerals throughout the drawings represent the same or similar components or components having the same or similar functions.

[0037] As shown in FIG. 1, a related art display device includes a plurality of pixel islands S and a plurality of cylindrical lenses Z arranged at intervals along the row direction X and the column direction Y. Each pixel island S has a plurality of subpixels O8 arranged at intervals along the row direction X. M cylindrical lenses Z cover N columns of subpixels, solving the macroscopic moiré fringe problem but creating the microscopic moiré fringe problem. Within a unit with a period of M=5, the regions corresponding to each cylindrical lens have different luminance at different spatial viewing angles. The luminance of the five cylindrical lens regions seen at any viewing angle varies. The relative luminance distribution of the five regions seen at any angle is shown in FIG. 2, and the visual sensation experienced by humans is shown in FIG. 3. Each of the five regions has a dark region with the lowest luminance. Connecting the dark regions forms thin stripes. The spacing between the thin stripes is large (approximately 727.2 μm), making them easily noticeable to the human eye, resulting in the display device having the microscopic moiré fringe problem.

[0038] In the present embodiment, as shown in FIG. a display panel 01 including a plurality of pixel overlap units 04 arranged along an array in a row direction X and a column direction Y, each pixel overlap unit 04 including a plurality of pixel islands S arranged continuously in the column direction, each pixel island S including a plurality of sub-pixels 08 arranged at intervals along the row direction X, the plurality of pixel overlap units 04 including a plurality of pixel overlap unit rows 013 arranged along the column direction Y, the sub-pixels 08 in any two adjacent pixel overlap unit rows 013 being arranged with a shift in the row direction X; a spectroscopic module 02 located on a display side of the display panel 01, the spectroscopic module 02 including a plurality of spectroscopic overlapping units 03 extending along a column direction Y and successively arranged in a row direction X, the spectroscopic overlapping units 03 including M spectroscopic structures A extending along the column direction Y and successively arranged in the row direction X, each spectroscopic overlapping unit 03 corresponding to an N-column sub-pixel in a pixel overlapping unit row, M and N being integers greater than 1, and M and N being relatively prime; A display device including:

[0039] Note that, "the sub-pixels in two adjacent pixel overlap unit rows are arranged with a shift in the row direction" means that the centers of the sub-pixels in two adjacent pixel overlap unit rows are not aligned in a straight line in the column direction.

[0040] In the display device provided by the present embodiment, M spectral structures correspond to N columns of subpixels in a pixel overlap unit row, where M and N are integers greater than 1. That is, the spectral structures and subpixels have a many-to-many correspondence relationship, which prevents the spectral structures from being too small in size in the row direction, thereby avoiding increased difficulty in manufacturing the spectral module and avoiding the display effect being affected by the increased divergence angle of the subpixel light due to diffraction by the spectral structures being too small, increasing inter-view interference. Furthermore, the subpixels in at least two adjacent pixel overlap unit rows are staggered in the row direction, which disrupts the distribution of dark areas corresponding to the spectral overlap units. The staggered arrangement of the dark areas prevents the formation of continuous thin stripes in the column direction, thereby mitigating the problem of micromolar stripes.

[0041] Note that each spectral overlap unit corresponds to an Nth column sub-pixel in a pixel overlap unit row, meaning that the orthogonal projection of each spectral overlap unit on the plane where the display panel is located overlaps with the orthogonal projection of the Nth column sub-pixel in the pixel overlap unit row on the plane where the display panel is located. Because the sub-pixels in any two adjacent pixel overlap unit rows are offset in the row direction, for example, for some pixel overlap unit rows, the orthogonal projection of the spectral overlap unit on the plane where the display panel is located completely covers the orthogonal projection of the Nth column sub-pixel in those pixel overlap unit rows on the plane where the display panel is located. For the remaining pixel overlap unit rows, the orthogonal projection of the spectral overlap unit on the plane where the display panel is located does not completely cover the orthogonal projection of the Nth column sub-pixel in those pixel overlap unit rows on the plane where the display panel is located. For sub-pixels located on the periphery of the spectral overlap unit, the orthogonal projection of the spectral overlap unit on the plane where the display panel is located covers only a partial area of ​​the orthogonal projection of those sub-pixels on the plane where the display panel is located.

[0042] In some embodiments, as shown in Figure 4, any sub-pixels 08 in any two adjacent pixel overlap unit rows 013 are offset in the row direction X. Therefore, there are no areas adjacent to a dark area in the column direction, which prevents the dark areas from forming continuous thin stripes in the column direction and effectively solves the problem of micromolar stripes.

[0043] In addition, the display device provided by the embodiments of the present application can be applied to three-dimensional (3D) display and can switch between 3D and 2D display. The pixel island can be a subpixel of 2D display, and one pixel island includes multiple subpixels, so that the same resolution as 2D display can be maintained in 3D display mode. When combined with a human eye-tracking system, it can realize a multi-view display with a large viewing angle, and can also realize a 3D display with a higher pixel density (ppi), which has a larger amount of information and lower color interference between adjacent views.

[0044] In practical implementation, the dispersive structure is for controlling the light output angle of each sub-pixel to achieve directional light emission.

[0045] In a specific implementation, the display panel may 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.

[0046] In some embodiments, as shown in FIG. 4 , one pixel overlap unit 04 in the column direction Y includes three pixel islands S arranged consecutively; Within one pixel overlap unit 04, the sub-pixels 08 of the same pixel island S display the same color, while the sub-pixels 08 of different pixel islands S display different colors.

[0047] In some embodiments, as shown in FIG. 4 , one pixel overlap unit 04 includes a first pixel island 05, a second pixel island 06, and a third pixel island 07, where the first pixel island 05 includes a plurality of red subpixels R, the second pixel island 06 includes a plurality of green subpixels G, and the third pixel island 07 includes a plurality of blue subpixels B.

[0048] In some embodiments, as shown in FIG. 4, each sub-pixel 08 in a row of pixel islands S displays the same color.

[0049] In some embodiments, as shown in FIG. 4 , a plurality of pixel overlap unit rows 013 are divided into a plurality of pixel overlap unit sets 014, each of which includes M pixel overlap unit columns 013, and in each pixel overlap unit set 014, the sub-pixels 08 in any two adjacent pixel overlap unit rows 013 are arranged with a shift in the row direction X, and each pixel overlap unit set 014 is divided into sub-units 015 that correspond one-to-one to the spectral overlap units 03, i.e., the portions of each pixel overlap unit set 014 that correspond to the M spectral structures A are the sub-units 015.

[0050] 4, M=5, i.e., the pixel overlap unit set 014 includes five pixel overlap unit rows 013. Only one subunit 015 is shown in Fig. 4. That is, only the portion of the pixel overlap unit set 014 corresponding to the five dispersing structures A is shown.

[0051] In some embodiments, as shown in FIG. 4 , in a sub-unit, the ratio of the position displacement vector Hj in the row direction X of the cth sub-pixel 08 in the jth pixel overlap unit row 013 and the cth sub-pixel 08 in the 1st pixel overlap unit row 013 to the sub-pixel width h1 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, unequal to M, and not equal to an integer multiple of M.

[0052] That is, in the embodiment of the present application, each sub-pixel in the second pixel overlap unit row to each sub-pixel in the Mth pixel overlap unit row in each sub-unit is arranged with a shift of Jj×h1 relative to the sub-pixel in the first pixel overlap unit row.

[0053] Taking the row direction X as shown in FIG. 4 as an example, the row direction X is the left-right extending direction in the figure, and the sub-pixel 08 in the j-th pixel overlap unit row 013 may be shifted to the left relative to the sub-pixel 08 in the first pixel overlap unit row 013, in which case Hj is positive, Jj=+E / M, and the sub-pixel 08 in the j-th pixel overlap unit row 013 may be shifted to the right relative to the sub-pixel 08 in the first pixel overlap unit row 013, in which case Hj is negative, Jj=-E / M.

[0054] In some embodiments, in each pixel overlap unit set, the displacement vectors of subpixels in different subunits located in the same pixel overlap unit row are the same, i.e., for M pixel overlap unit rows 013 in each pixel overlap unit set, the ratio of the displacement vector Hj in the row direction of the subpixel in the jth pixel overlap unit row to the subpixel in the 1st pixel overlap unit row to the width h1 in the sub-luminance row direction X is Jj = ±E / M.

[0055] The relative luminance distribution of one subunit area corresponding to M spectral structures is divided into M*M luminance areas. For one subunit, if the subpixels in the second pixel overlap unit row through the Mth pixel overlap unit row are offset relative to the subpixels in the first pixel overlap unit row, the dark areas with the lowest luminance in the luminance areas corresponding to the second to Mth pixel overlap unit rows are offset relative to the dark area corresponding to the first pixel overlap unit row, thereby disrupting the distribution of dark areas in the areas corresponding to the subunits and displacing the dark areas. Furthermore, the display panel includes multiple pixel overlap unit sets, and each pixel overlap unit set includes multiple subunits. That is, a subunit is the smallest unit that disrupts the dark area distribution. Because the dark area distribution of each subunit is disrupted in the column direction, the formation of continuous thin stripes of dark areas in the column direction across the entire display device can be prevented, thereby resolving the problem of micromolar stripes.

[0056] In 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.

[0057] In addition, when the difference between two Jj is M or an integer multiple of M, for example, Jj is -6 / 5 and -1 / 5, respectively, the number of luminance areas in the gap between the dark area of ​​the row in question and the dark area of ​​the first row when Jj is -6 / 5 is the same as the number of luminance areas in the gap between the dark area of ​​the row in question and the dark area of ​​the first row when Jj is -1 / 5.

[0058] In some embodiments, among the 2nd to Mth pixel overlap unit rows in a sub-unit, the Jj corresponding to any two pixel overlap unit rows are not equal, and the absolute value of the difference between the Jj corresponding to any two pixel overlap unit rows is not an integer greater than or equal to 1. Therefore, in one pixel overlap unit set, there is no situation in which dark regions are located in the same column in the column direction, which allows the distance between two dark regions arranged in the column direction to be increased, and prevents the appearance of thin lines in the column direction that are easily noticeable to the human eye.

[0059] In some embodiments, in a subunit, the ratio ΔJ between the displacement vector in the row direction of the c-th subpixel in two at least partially adjacent pixel overlap unit rows and the width of the subpixel in the row direction is

[0060]

number

[0061] or

[0062]

number

[0063] and C is an integer greater than 0, so that the dark areas in two adjacent pixel overlap unit rows are spaced apart by at least one brightness area, thereby avoiding continuous dark areas and making it easier for the human eye to not perceive the presence of thin lines extending in the tilt direction, thereby effectively solving the problem of micro-Moiré fringes.

[0064] In some embodiments, E is an integer greater than or equal to 1 and less than or equal to M-1, i.e., the displacement vector of a subpixel does not exceed the width of one subpixel in the row direction X, which can disrupt the distribution of dark areas in the region corresponding to the subunit and prevent the displacement distance of the subpixels from being too large, which is beneficial to the rational use of the display panel space.

[0065] When M=5 and E is an integer between 1 and M-1, Jj may be one of -4 / 5, -3 / 5, -2 / 5, -1 / 5, 1 / 5, 2 / 5, 3 / 5, and 4 / 5. If Jj is -4 / 5, the dark area corresponding to the row is shifted four luminance areas to the right relative to the dark area corresponding to row 1 (the dark area corresponding to the row is separated by three luminance areas from the dark area corresponding to row 1); if Jj is -3 / 5, the dark area corresponding to the row is shifted three luminance areas to the right relative to the dark area corresponding to row 1 (the dark area corresponding to the row is separated by two luminance areas from the dark area corresponding to row 1); if Jj is -2 / 5, the dark area corresponding to the row is shifted two luminance areas to the right relative to the dark area corresponding to row 1 (the dark area corresponding to the row is separated by one luminance area from the dark area corresponding to row 1); and if Jj is -1 / 5, the dark area corresponding to the row is shifted one luminance area to the right relative to the dark area corresponding to row 1 (the dark area corresponding to the row is separated by a luminance area of ​​zero). , when Jj is 1 / 5, the dark area corresponding to the row is offset one luminance area to the left with respect to the dark area corresponding to row 1 (the dark area corresponding to the row and the dark area corresponding to row 1 are separated by a luminance area of ​​0); when Jj is 2 / 5, the dark area corresponding to the row is offset two luminance areas to the left with respect to the dark area corresponding to row 1 (the dark area corresponding to the row and the dark area corresponding to row 1 are separated by one luminance area); when Jj is 3 / 5, the dark area corresponding to the row is offset three luminance areas to the left with respect to the dark area corresponding to row 1 (the dark area corresponding to the row and the dark area corresponding to row 1 are separated by two luminance areas); and when Jj is 4 / 5, the dark area corresponding to the row is offset four luminance areas to the left with respect to the dark area corresponding to row 1 (the dark area corresponding to the row and the dark area corresponding to row 1 are separated by three luminance areas).

[0066] 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.

[0067] In concrete implementation, for example, J2 is -2 / 5, J3 is 1 / 5, J4 is -1 / 5, and J5 is 2 / 5, and accordingly, as shown in Figure 4, H2 = (-2 / 5) h1, H3 = (1 / 5) h1, H4 = (-1 / 5) h1, and H5 = (2 / 5) h1.

[0068] Of course, in concrete implementation, J2 may be 3 / 5, J3 may be -4 / 5, J4 may be 4 / 5, and J5 may be -3 / 5.

[0069] 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 luminance distribution of one subunit area corresponding to five spectral structures is as shown in Figure 5. The relative luminance distribution of one subunit area corresponding to five spectral structures is divided into 5*5 luminance areas, and the area corresponding to a relative luminance of 55.6% is a dark area. As shown in Figure 5, the visual sensory effect of one subunit area is as shown in Figure 6, where the dark areas of different rows are not located in a column, i.e., the dark areas of different rows are offset, and the visual sensory effect of multiple subunit areas is as shown in Figure 7.

[0070] When the dark regions shown in FIG. 7 are connected, thin dark region lines are also formed, but the extension direction of the thin dark region lines is a direction in which the angle between the row direction and the column direction is greater than 0 (hereinafter referred to as the inclined direction). The spacing between the thin dark region lines extending along the inclined direction is 391.6 μm. This spacing is much smaller than the spacing between the thin dark region lines extending in the column direction in the related art (727.2 μm). The spacing of 391.6 μm is hardly noticeable at a viewing distance of 300 mm, but in general, the viewing distance when a user uses a display device is 630 mm. At this viewing distance, the presence of the thin lines extending in the inclined direction is hardly noticeable to the human eye, effectively resolving the problem of micro-moiré fringes.

[0071] In some embodiments, when E is an integer between 1 and M-1, inclusive, in a sub-unit, in the 2nd to Mth pixel overlap unit rows, the Jj corresponding to any two pixel overlap unit rows are not equal, and if one Jj corresponding to two pixel overlap unit rows is positive and the other is negative, the sum of the absolute values ​​of the Jj corresponding to the two pixel overlap unit rows is not equal to 1. Therefore, in one pixel overlap unit set, dark regions are not located in the same column in the column direction, and the distance between two dark regions arranged in the column direction can be increased, preventing the appearance of thin lines in the column direction that are easily noticeable to the human eye.

[0072] In some embodiments, as shown in Figures 5 and 6, in a brightness region corresponding to one subunit, the central connecting lines of the multiple dark regions are not aligned on the same line. That is, in a brightness region corresponding to one subunit, the multiple dark regions are not sequentially arranged along a direction in which the angle between the row direction and the column direction is greater than 0 (hereinafter referred to as the "slope direction"), but are distributed on multiple lines extending along the slope direction. Therefore, compared to a situation in which the central connecting lines of the multiple dark regions are aligned on the same line, as shown in Figure 7, the distance between the thin lines of the dark regions is small across the entire display device, which is advantageous in that the thin lines extending in the slope direction are not easily detected by the human eye, and the problem of micro-Moiré fringes is effectively resolved.

[0073] In some embodiments, when E is an integer between 1 and M-1, the ratio ΔJ between the row direction displacement vector of the cth subpixel in two at least partially adjacent pixel overlap unit rows in a subunit and the row direction width of the subpixel is not equal to ±1 / M or ±(M-1) / M, which is advantageous in that the dark regions in the two adjacent pixel overlap unit rows are spaced apart by at least one brightness region, avoiding a continuation of dark regions and preventing the presence of thin lines extending in the oblique direction from being easily detected by the human eye, thereby effectively resolving the problem of micro-Moiré fringes.

[0074] In some embodiments, each spectral overlap unit corresponds to K columns of pixel islands in a pixel overlap unit row, where K is a moire fringe integer greater than 1.

[0075] In the display device provided by the embodiments of the present application, each spectral overlap unit corresponds to K columns of pixel islands in a pixel overlap unit row, i.e., M spectral structures correspond to K columns of pixel islands in a pixel overlap unit row, where M and K are both integers greater than 1. That is, there is a many-to-many correspondence between the spectral structures and the pixel island rows. This prevents the spectral structures from being too small in size in the row direction, which can avoid increasing the difficulty of manufacturing the spectral module, and also avoids the display effect being affected by an increase in the divergence angle of the output light of the sub-pixels due to diffraction by a spectral structure that is too small, which can increase interference between views.

[0076] In some embodiments, N / K is an integer, i.e., N columns of sub-pixels in a pixel overlap unit row corresponding to M spectroscopic units are evenly divided into multiple columns of pixel islands.

[0077] In a specific implementation, as shown in FIG. 4 , each pixel island S includes n sub-pixels 08 spaced apart along the row direction X, where n is an integer greater than 1, and each spectral overlap unit corresponds to K columns of pixel islands in a pixel overlap unit row, where N=K*n, K is an integer greater than 1, and M and K are relatively prime.

[0078] Alternatively, in some embodiments, N and K are relatively prime, i.e., the N columns of sub-pixels in a pixel overlap unit row corresponding to M spectroscopic units are not evenly divided into multiple columns of pixel islands.

[0079] In a specific implementation, even if the N columns of sub-pixels in a pixel overlap unit row corresponding to M spectroscopic units are not evenly divided into multiple columns of pixel islands, the spectroscopic units and pixel islands still have a many-to-many relationship, which still prevents the size of the spectroscopic structure in the row direction from being too small and avoids increasing the difficulty of manufacturing the spectroscopic units. It also prevents the display effect from being affected by the increase in the divergence angle of the sub-pixel light output due to diffraction by the spectroscopic structure that is too small, and the increase in interference between views.

[0080] In some embodiments, the width of the M light-splitting structures in the horizontal direction is equal to the width of the N columns of sub-pixels in one pixel overlap unit row.

[0081] In some embodiments, the light-emitting areas of the N column sub-pixels in a pixel overlap unit row form a spatially continuous light-emitting area with the emitted light beams dispersed through the M dispersing structures.

[0082] In the display device provided by the embodiments of the present application, the N columns of sub-pixels correspond to M spectral structures, and the light-emitting regions of each sub-pixel of the N columns of sub-pixels are arranged with a spatial offset. Since the dimensions of the spectral structures in the row direction are small, the human eye cannot distinguish which specific spectral structure the light comes from for the N columns of sub-pixels corresponding to the M spectral structures. Therefore, the output light beams that are spectrally separated from the N columns of sub-pixels through the M spectral structures above them appear to form a spatially continuous light-emitting region, and the human eye does not perceive any "black regions" as they move through the visible space.

[0083] In some embodiments, the sub-pixel includes a sub-pixel aperture region, and the ratio of the total width of the n sub-pixel aperture regions in the row direction to the width of the pixel island is 0.9 / M or more and 1 or less. That is, the aperture ratio of the sub-pixel in the pixel island is 0.9 / M or more and 1 or less.

[0084] In some embodiments, the light-emitting regions of the N column sub-pixels in a pixel overlap unit row in the row direction are spatially complementary to each other in the row direction.

[0085] 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 1 / M, i.e., the aperture ratio of the subpixels in the pixel island is 1 / M. This arrangement allows the subpixels below each spectral overlapping unit to be offset from the corresponding spectral structures in a complementary arrangement, and the light-emitting regions of the N columns of subpixels are spatially complementary to each other, i.e., the viewing optical paths are closely spaced, thereby reducing macromolar stripes and improving the display effect.

[0086] In some embodiments, there is spatial overlap between the light emitting areas of the N column sub-pixels in a pixel overlap unit row in the row direction.

[0087] In some embodiments, there is uniform spatial overlap between the light-emitting areas of the N column sub-pixels in a pixel overlap unit row in the row direction.

[0088] In some embodiments, the ratio of the width of the sub-pixel aperture region to the width of the pixel island in the row direction is i / M, where i is an integer greater than 1 and less than or equal to M-1.

[0089] In the display device provided by the embodiments of the present application, M dispersive structures correspond to N column subpixels in one pixel overlap unit row, and M dispersive structures correspond to K pixel islands in one pixel overlap unit row, i.e., there is a many-to-many relationship between the subpixels and dispersive structures, and there is also a many-to-many relationship between the pixel islands and dispersive structures, and when the width of the M dispersive structures in the row direction is equal to the width of the N column subpixels in the pixel overlap unit row, increasing the number of dispersive structures does not make the row direction dimensions of the dispersive structures too small to make them difficult to fabricate. Furthermore, when the subpixel aperture ratio is i / M, where i is an integer greater than 1 and equal to or less than M-1, compared to when there is a one-to-many relationship between the pixel islands and dispersive structures, the subpixel aperture ratio can be increased when the number of dispersive structures is the same.

[0090] In specific implementation, each spectral overlap unit corresponds to K columns of pixel islands, where N=K*n, the width of the N columns of sub-pixels is the width of the K columns of pixel islands, and the width of the M spectral structures in the horizontal direction is equal to the width of the K columns of pixel islands.

[0091] In a specific implementation, each spectral overlap unit corresponds to K columns of pixel islands, where N=K*n, and the light-emitting areas of the sub-pixels in the K pixel islands are arranged with a spatial offset, so that the light emitted from the sub-pixels in the K pixel islands forms a spatially continuous light-emitting area after being dispersed through M spectral structures.

[0092] It should be noted that the space in the statement "the light-emitting regions of the sub-pixels in the K pixel islands are arranged so as to be spatially shifted" refers to the visible space of the display device.

[0093] In the display device provided by the embodiment of the present application, K pixel islands correspond to M dispersive structures, and the light-emitting areas of each sub-pixel in the K pixel islands are spatially offset. Because the dimensions of the dispersive structures in the row direction are small, the human eye cannot distinguish which dispersive structure the light comes from for the K pixel islands covered by the M dispersive structures. Therefore, to the human eye, the emitted light beams dispersed by the K pixel islands through the M dispersive structures above them appear to form a spatially continuous light-emitting area, and the human eye does not perceive any "black areas" when moving in the visible space.

[0094] The viewing angles include a main lobe viewing angle and a side lobe viewing angle. The main lobe viewing angle refers to the viewing angle formed spatially after light emitted from a sub-pixel is dispersed through the dispersive structure directly above it. The side lobe viewing angle refers to the viewing angle formed spatially after light emitted from a sub-pixel is dispersed through the dispersive structure adjacent to the dispersive structure directly above it. For example, light passing through a first dispersive structure adjacent to the dispersive structure directly above is a first-order side lobe viewing angle, and light passing through a second dispersive structure adjacent to the dispersive structure directly above is a second-order side lobe viewing angle, and so on.

[0095] To better understand this solution, the following will take the viewing angle of the main lobe as an example. When each spectral overlapping unit corresponds to K columns of pixel islands, where N=K*n, the light-emitting areas of the sub-pixels in the K pixel islands are spatially offset, and the emitted light from the sub-pixels in the K pixel islands forms a spatially continuous light-emitting area after passing through M spectral structures and being dispersed.

[0096] In practice, among the M number of dispersive structures arranged in the row direction and the plurality of sub-pixels corresponding to each dispersive structure, the difference in viewpoint between two adjacent sub-pixels is M.

[0097] In some embodiments, K is 4, M is 5, n is 4, the aperture ratio of the subpixel is 1 / 5, and the optical path diagram of the pixel island in column K is as shown in Figures 8 and 9. The five spectral structures correspond to the four columns of pixel islands in one pixel overlap unit row, and each row in the four columns of pixel islands includes 16 subpixels, respectively, labeled as the first subpixel 1 to the sixteenth subpixel 16. 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. 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. The fourth pixel island S4 includes the thirteenth subpixel 13, the second subpixel 2, the seventh subpixel 7, and the twelfth subpixel 12. The spectral structures corresponding to the 16 subpixels are referred to as the first spectral structure A1 to the fifth spectral structure A5, respectively. As shown in Figure 8, the first spectral structure A1 covers the first subpixel 1, the sixth subpixel 6, the eleventh subpixel 11, and the sixteenth subpixel 16, the second spectral structure A2 covers the fifth subpixel 5, the tenth subpixel 10, and the fifteenth subpixel 15, the third spectral structure A3 covers the fourth subpixel 4, the ninth subpixel 9, and the fourteenth subpixel 14, the fourth spectral structure A4 covers the third subpixel 3, the eighth subpixel 8, and the thirteenth subpixel 13, and the fifth spectral structure A5 covers the second subpixel 2, the seventh subpixel 7, and the twelfth subpixel 12. As shown in Figure 8, the relative positional relationship between each sub-pixel and the spectral structure within the four pixel islands does not form an overlapping unit. When each sub-pixel is connected in viewpoint order while maintaining the relative position between each sub-pixel and the spectral structure, as shown in Figure 9, after the sub-pixels corresponding to each spectral structure are connected, the positions of the sub-pixels are complementary, that is, there is no gap between each sub-pixel, and a phase-complementary arrangement is formed with respect to the relative positional relationship with the spectral structure. Accordingly, the light-emitting areas of each sub-pixel within the four pixel islands are arranged with a spatial offset, and the light-emitting areas of each sub-pixel within the four pixel islands also form a phase-complementary arrangement in space.As shown in Figure 8, because there are gaps between the first subpixel 1 to the fifth subpixel 5, the light emitted from adjacent subpixels corresponding to the same spectral structure has discontinuous emission angles in space after passing through the same spectral structure A. However, the relative positions of each subpixel in the four pixel islands and the five spectral structures A are in a displaced arrangement, and the light-emitting regions of each subpixel in the four pixel islands are spatially offset, so the emission angles of each spectral structure A are also displaced. Because the dimensions of the spectral structures A are small, the human eye cannot distinguish which spectral structure A the light is specifically emitting from. Therefore, as shown in Figure 9, the light emitted from the 16 subpixels in the four pixel islands appears to the human eye to form a spatially continuous emission region after passing through the five spectral structures and being dispersed, and the human eye cannot see any "black regions" when moving through space.

[0098] The continuity of the sidelobe viewing angles is similar to the continuity of the mainlobe viewing angles. The K pixel islands can complement two discontinuous first-order sidelobe viewing angles through adjacent spectral structures into one continuous first-order sidelobe viewing angle. Furthermore, since the horizontal width of the M spectral structures is equal to the width of the K pixel islands in one pixel overlap unit row, the mainlobe viewing angle boundary and the sidelobe viewing angle boundary are parallel. Because the human eye cannot distinguish the gap between the mainlobe viewing angle boundary and the sidelobe viewing angle boundary, the observed mainlobe viewing angle and the sidelobe viewing angle are also continuous. Similarly, the first-order sidelobe viewing angle and the second-order sidelobe viewing angle are continuous, and the second-order sidelobe viewing angle and the third-order sidelobe viewing angle are also continuous, and so on. Therefore, a continuous viewing angle is obtained.

[0099] In some embodiments, K is 4, M is 5, n is 4, the subpixel aperture ratio is 4 / 5, and the optical path diagrams of K pixel islands in one pixel unit row are as shown in Figures 10 and 11. The four pixel islands corresponding to the five spectral structures include 16 subpixels, respectively labeled as the first subpixel 1 to the sixteenth subpixel 16, 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. 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. The fourth pixel island S4 includes the thirteenth subpixel 13, the second subpixel 2, the seventh subpixel 7, and the twelfth subpixel 12. The spectral structures corresponding to the 16 subpixels are respectively labeled as the first spectral structure A1 to the fifth spectral structure A5. As shown in FIG. 10 , the first spectral structure A1 covers the first subpixel 1, the sixth subpixel 6, the eleventh subpixel 11, and part of the sixteenth subpixel 16. The second spectral structure A2 covers part of the sixteenth subpixel 16, the fifth subpixel 5, the tenth subpixel 10, and part of the fifteenth subpixel 15. The third spectral structure A3 covers part of the fifteenth subpixel 15, the fourth subpixel 4, the ninth subpixel 9, and part of the fourteenth subpixel 14. The fourth spectral structure A4 covers part of the fourteenth subpixel 14, the third subpixel 3, the eighth subpixel 8, and the thirteenth subpixel 13. The fifth spectral structure A5 covers the second subpixel 2, the seventh subpixel 7, and the twelfth subpixel 12. As shown in Figure 10, the relative positional relationship between each sub-pixel and the spectral structure within the four pixel islands does not constitute an overlapping means. When each sub-pixel is connected in viewpoint order while maintaining the relative position of each sub-pixel and the spectral structure, as shown in Figure 11, after the sub-pixels corresponding to each spectral structure are connected together, the positions of the sub-pixels overlap and the relative positional relationship with the spectral structure is shifted but overlapping, forming an arrangement scheme. Accordingly, the light-emitting areas of each sub-pixel within the four pixel islands are arranged with a spatial shift, and the light-emitting areas of each sub-pixel within the four pixel islands are also spatially shifted to form a complementary arrangement scheme.10, because there are gaps between the first subpixel 1 to the fifth subpixel 5, the light emitted from adjacent subpixels corresponding to the same spectral structure passes through the same spectral structure A, and the spatial emission angles are discontinuous. However, because the relative positions of each subpixel in the four pixel islands and the five spectral structures A are arranged with a shifted but uniform overlap, the light-emitting regions of each subpixel in the four pixel islands are arranged with a shifted but uniform overlap, and therefore the emission angles of each spectral structure A also shift but uniformly overlap. Because the dimensions of the spectral structures A are small, the human eye cannot distinguish which spectral structure A the light is specifically emitting from. Therefore, as shown in FIG. 11, the emitted light from the 16 subpixels in the four pixel islands after being dispersed through the five spectral structures appears to the human eye to form a spatially continuous emission area, and the human eye cannot see any "black areas" when moving through space.

[0100] 10 , the ratio of the total width n×h1 of the n sub-pixel aperture regions in the row direction 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 under the spectral overlapping units to be arranged in a uniformly overlapping arrangement with a shift relative to the position of the corresponding spectral structure, so that the light-emitting areas of the sub-pixels in the K pixel islands spatially overlap uniformly, i.e., the viewpoint optical paths overlap uniformly, which similarly eliminates macro-Moiré fringes and improves the display effect.

[0101] In specific implementation, when the light-emitting areas of the subpixels in the K pixel islands are spatially uniformly overlapped, the ratio of the area of ​​the overlapping area between two adjacent subpixels to the area of ​​one of the subpixels is (i-1) / i, and the ratio of the area of ​​the overlapping area between two adjacent subpixels to the area of ​​one of the subpixels is (i-1) / M.

[0102] Note that when the ratio of the total width n×h1 of the n subpixel aperture regions in the row direction to the width h2 of the pixel island is 1 / M, i.e., when i=1, the emissive regions of the subpixels do not spatially overlap. When i=2, the ratio of the area of ​​the overlapping region of two adjacent subpixel emissive regions to the area of ​​one of those subpixels is 1 / 2, and the ratio of the area of ​​the overlapping region of two adjacent subpixel emissive regions to the area of ​​one of those subpixels is 1 / M. When i=3, the ratio of the area of ​​the overlapping region of two adjacent subpixel emissive regions to the area of ​​one of those subpixels is 2 / 3, and the ratio of the area of ​​the overlapping region of two adjacent subpixel emissive regions to the area of ​​one of those subpixels is 2 / M. When i=4, the ratio of the area of ​​the overlapping region of two adjacent subpixel emissive regions to the area of ​​one of those subpixels is 3 / 4, and the ratio of the area of ​​the overlapping region of two adjacent subpixel emissive regions 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 two adjacent subpixel light-emitting regions to the area of ​​the light-emitting region of one of the subpixels is (M-2) / (M-1), and the ratio of the area of ​​the overlapping region of two adjacent subpixel light-emitting regions to the area of ​​one of the subpixels is (M-2) / M, and so on below, and will not be explained again.

[0103] 10, the ratio of the total width of the n sub-pixel aperture regions to the width of the pixel island in the row direction is (M-1) / M, i.e., 4 / 5. That is, the aperture ratio of the sub-pixels in the pixel island in FIG. 4 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 under the condition that the light-emitting regions of the sub-pixels in the K pixel islands spatially overlap uniformly in the row direction. Of course, in a specific implementation, the aperture ratio of the sub-pixels in the pixel island may be 2 / M, 3 / M, etc.

[0104] In some embodiments, as shown in FIG. 12, the display device may include: It further includes a spacer medium layer 09 located between the spectroscopic module 02 and the display panel 01 .

[0105] In some embodiments, the dispersing structure is a cylindrical lens.

[0106] 12, the cylindrical lens 010 includes a first resin layer 011 having protrusions 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 that of the first resin layer 011.

[0107] Alternatively, in some embodiments, the cylindrical lens is a liquid crystal lens.

[0108] Of course, in specific implementation, the dispersing structure may be a structural device such as a geometric lens, a diffractive lens, a liquid lens, etc., which can control the light output direction of the sub-pixel.

[0109] In some embodiments, the display device comprises: It further includes an eye tracking system for determining the position of the user's eyes in real time.

[0110] The display device provided in the embodiments of the present application may be any product or component with a display function, such as a mobile phone, a tablet PC, a television, a display, a laptop, a digital photo frame, a navigation system, a smart watch, a fitness bracelet, a personal digital assistant, etc. Other essential components of the display device should be understood and possessed by those skilled in the art, and will not be described again here and should not be considered as limitations on the present application.

[0111] In view of the above, in the display device provided by the embodiment of the present application, M spectral structures correspond to N column subpixels in a pixel overlap unit row, where M and N are both integers greater than 1, i.e., the spectral structures and subpixels have a many-to-many correspondence relationship. This avoids the spectral structures being too small in size in the row direction, which increases the difficulty of manufacturing the spectral module and also avoids the display effect being affected by the increased divergence angle of the subpixels due to diffraction by the spectral structures being too small, which increases inter-view interference. Furthermore, the subpixels in at least two adjacent pixel overlap unit rows are staggered in the row direction, which disrupts the distribution of dark areas corresponding to the spectral overlap units. The staggered arrangement of the dark areas prevents the formation of continuous thin stripes in the column direction, effectively mitigating the problem of micromolar stripes.

[0112] Although preferred embodiments of the present invention have been described, other variations and modifications to these embodiments may be made by those skilled in the art once the basic inventive concept is grasped. It is therefore intended by the appended claims to cover the preferred embodiments and all such variations and modifications that fall within the scope of the present invention.

[0113] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Therefore, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations as well.
