[0028] Super multi view 3D light field display technology is a technology that can realize naked eye 3D display, which can better restore light field information and enhance visual experience. However, the viewing angle of super multi view 3D light field display devices in related technologies is small, which is only suitable for small-sized products and cannot meet the needs of medium and large-sized display devices formed by splicing.

[0029] In order to at least solve the above technical problems existing in the related art, the present disclosure provides a display device, such as Figure 1 As shown, this may include:

[0030] The display panel 101 includes a plurality of pixel islands 102 arranged at intervals along a row direction X and a column direction Y, wherein the pixel islands 102 in odd rows and the pixel islands 102 in even rows are staggered along the row direction X, and the adjacent boundaries of the pixel islands 102 in odd columns and the pixel islands 102 in even columns extending along the column direction Y are collinear (i.e., overlapped); each pixel island 102 includes a plurality of sub-pixels P arranged at intervals along the row direction X and the column direction Y, and the sub-pixels P in each row in each pixel island are sequentially staggered along the row direction X, and the adjacent boundaries of the sub-pixels P extending along the column direction Y are collinear; optionally, the display panel 101 may be a medium or large-sized display panel spliced ​​by a plurality of Mini LED display screens or a plurality of Micro LED display screens;

[0031] The light-splitting component 103 is located on the display surface side of the display panel 101, and includes a plurality of lenses 104 extending along the column direction Y and arranged at intervals along the row direction X, and each two adjacent lenses 104 form a light-splitting repetitive unit 105; one lens 104 is arranged corresponding to a column of pixel islands 102, and the emission light of the two columns of pixel islands 102 corresponding to each light-splitting repetitive unit 105 is closely connected through the main lobe viewing angles formed by the corresponding lenses 104; wherein, the main lobe viewing angle refers to the viewing angle formed in space after the emission light of the pixel island 102 is split by the lens 104 directly above it, and close connection means that the two main lobe viewing angles are directly in contact in space and have no overlapping area.

[0032] In the above-mentioned display device provided by the embodiment of the present disclosure, by arranging the pixel islands 102 to be staggered in the row direction X and closely connected in the column direction Y, and arranging the multiple sub-pixels P included in the pixel islands 102 to be staggered in the row direction X and closely connected in the column direction Y, in conjunction with the lenses 104 corresponding to the pixel islands 102, the emission light of the two columns of pixel islands 102 corresponding to each light-splitting repetitive unit 105 can be closely connected through the main lobe viewing angles formed by the corresponding lenses 104, thereby realizing the splicing of the viewing angles, increasing the viewing angle of the light field display, and satisfying the viewing of multiple people.

[0033] In addition, in the present disclosure, light is continuously emitted inside the pixel island 102 and between each pixel island 102, so that the pixel island 102 is projected to the corresponding position in the space to form a continuous viewing angle, and the human eye will not see the black area when moving in the space, thereby eliminating the moiré pattern caused by the black area.

[0034] In addition, compared with the liquid crystal (LCD) products or organic electroluminescent (OLED) products in the related art that use sub-pixels P as units for light field display, since the sub-pixels P of Mini LED or Micro LED can be made smaller, the resolution of a single pixel island 102 is higher, and the resolution of the display device obtained by splicing the pixel islands 102 is high enough, the present disclosure can achieve higher resolution light field display, with a larger amount of information and a more delicate picture (retina).

[0035] In some embodiments, in the above display device provided by the embodiments of the present disclosure, if Figure 2 As shown, the plurality of sub-pixels P in each pixel island 102 may include a light-emitting sub-pixel (i.e. Figure 2 There are digitally numbered sub-pixels) and floating sub-pixels (i.e. Figure 2 unnumbered sub-pixels in the graph); wherein, in each row of sub-pixels P of each pixel island 102, the distance between the luminous sub-pixel and the central axis O1 extending along the column direction Y of the pixel island 102 is smaller than the distance between the floating sub-pixel and the central axis O1 extending along the column direction Y of the pixel island 102, which is equivalent to that in each pixel island 102, the floating sub-pixel is located outside the luminous sub-pixel.

[0036] When performing light field display, the light emitted by the luminous sub-pixel after being lit forms a viewpoint in space through the lens 104; the floating sub-pixel is a sub-pixel that does not emit light. In some embodiments, the floating sub-pixel can be controlled by the pixel driving circuit not to emit light. Considering factors such as process deviation, the setting of the floating sub-pixel can meet the viewing angle splicing freedom of the pixel island 102, ensuring that the light emitted by the luminous sub-pixel is continuous and crosstalk-free after being emitted through the corresponding lens 104.

[0037] In some embodiments, in the above display device provided by the embodiments of the present disclosure, since the floating sub-pixel is not used for light field display, in order to allow the emission light of the light-emitting sub-pixel to be split by the corresponding lens 104, as shown in FIG. Figure 2 As shown, the lens 104 can be set to cover the luminous sub-pixel of the corresponding pixel island 102 but not cover the floating sub-pixel of the corresponding pixel island 102, and the central axis O2 of the lens 104 extending along the column direction Y is offset relative to the central axis O1 of the corresponding column of pixel islands 102 extending along the column direction.

[0038] Figure 2 It is shown that a pixel island 102 includes 27 sub-pixels P arranged in 3 rows and 27 columns, and each row of sub-pixels P includes 8 light-emitting sub-pixels and 1 floating sub-pixel. A light-splitting repeating unit 105 includes two lenses 104, which are marked as a first lens 1041 and a second lens 1042, wherein the first lens 1041 covers the light-emitting sub-pixels corresponding to a column of pixel islands 102, and does not cover the floating sub-pixels of the column of pixel islands 102; the second lens 1042 covers the light-emitting sub-pixels corresponding to a column of pixel islands 102, and does not cover the floating sub-pixels of the column of pixel islands 102. The 24 light-emitting sub-pixels contained in each pixel island 102 corresponding to the first lens 1041 are marked as the first light-emitting sub-pixel 1 to the twenty-fourth light-emitting sub-pixel 24, and the 24 light-emitting sub-pixels contained in each pixel island 102 corresponding to the second lens 1042 are marked as the twenty-fifth light-emitting sub-pixel 25 to the forty-eighth light-emitting sub-pixel 48. Furthermore, the arrangement of the light-emitting sub-pixels and the floating sub-pixels contained in the pixel island 102 corresponding to the first lens 1041 and the second lens 1042 in which the light-emitting sub-pixels are staggered in the row direction X and closely connected in the column direction Y can be equivalent to the arrangement of the light-emitting sub-pixels and the floating sub-pixels in a row in a continuous and close manner, such as Figure 3 shown.

[0039] Since the first light-emitting sub-pixel 1 to the twenty-fourth light-emitting sub-pixel 24 are in close contact, the light emitted from the first light-emitting sub-pixel 1 to the twenty-fourth light-emitting sub-pixel 24 after passing through the first lens 1041 is spatially continuous, forming a first main lobe viewing angle λ; and since the twenty-fifth light-emitting sub-pixel 25 to the forty-eighth light-emitting sub-pixel 48 are in close contact, the light emitted from the twenty-fifth light-emitting sub-pixel 25 to the forty-eighth light-emitting sub-pixel 48 after passing through the second lens 1042 is spatially continuous, forming a second main lobe viewing angle δ. By setting the offset distance d of the central axis O2 extending along the column direction Y of the lens 104 relative to the central axis O1 extending along the column direction of the corresponding column of pixel islands 102 to satisfy the above formula, it is ensured that the first main lobe viewing angle λ is in close contact with the second main lobe viewing angle δ, as shown in FIG. Figure 3 shown.

[0040] In addition, by Figure 3 It can be seen that the relative positions of the first light-emitting sub-pixel 1 to the twenty-fourth light-emitting sub-pixel 24 and the corresponding lens 104 are different, so 24 viewpoints located within the first main lobe viewing angle λ can be formed through the corresponding lens 104, which are viewpoints 1 to 24 respectively, that is, light intensity information of 24 different directions can be loaded in each pixel island 102. In the same way, the twenty-fifth light-emitting sub-pixel 25 to the forty-eighth light-emitting sub-pixel 48 can be formed through the corresponding lens 104 to be located within the second main lobe viewing angle δ. 24 viewpoints, which are viewpoints 25 to 48 respectively. Therefore, in the present disclosure, 48 viewpoints arranged in sequence along the row direction X in space are obtained by closely connecting the first main lobe viewing angle λ with the second main lobe viewing angle δ. In other words, the viewpoints formed after the emission light of each light-emitting sub-pixel corresponding to a splitting repetition unit 105 passes through the corresponding lens 104 are arranged in sequence along the row direction X in space.

[0041] Furthermore, in the above-mentioned display device provided by the embodiment of the present disclosure, relative to the light splitting repeating unit 105, the emission light of the light-emitting sub-pixels at the same position forms a viewpoint after passing through the respective corresponding lenses 104. In other words, the light-emitting sub-pixels with the same number in all pixel islands 102 in the present disclosure form the viewpoint with the same number, for example, the first light-emitting sub-pixels 1 in all pixel islands 102 form 1 viewpoint.

[0042] In some embodiments, in the display device provided by the embodiments of the present disclosure, since a wide viewing angle light field display can be achieved by only using the main lobe viewing angle to closely connect, in order to avoid the emission light of the light-emitting sub-pixel passing through the lens 104 next to the lens 104 directly above it to form a side lobe viewing angle in space, the emission light of the light-emitting sub-pixel with the smallest distance from the floating sub-pixel in each pixel island 102 (for example, L1 and L2) can be set to 48), total reflection occurs on the lens 104 corresponding to the adjacent pixel island 102 in the row direction X, such as Figure 3 shown.

[0043] In some embodiments, in the above display device provided by the embodiments of the present disclosure, if Figure 1 and Figure 3 As shown, it may also include: a shading layer 106 located on the side of the splitter component 103 away from the display panel, the shading layer 106 includes a plurality of shading structures BM extending along the column direction Y, the shading structures BM fill the gaps between the lenses 104, so that the light irradiated to the gaps between the lenses 104 is blocked by the shading structures BM, thereby avoiding interference with each viewpoint.

[0044] Optionally, in the display device provided in the embodiment of the present disclosure, in order to reduce the tolerance requirement and prevent the moiré caused by the black area caused by the process deviation, as shown in FIG. Figure 4 As shown, a plurality of redundant sub-pixels P' may also be provided. The redundant sub-pixels P' may be provided in the same row as at least some of the sub-pixels P corresponding to a lens 104 (e.g., the first lens 1041) in the light-splitting repetition unit 105, and in the same column as at least some of the sub-pixels P corresponding to another lens 104 (e.g., the second lens 1042). That is, the redundant sub-pixels P' may be provided in the same manner as the sub-pixels P contained in the pixel island 102.

[0045] It should be noted that, since the redundant sub-pixel P' is arranged in the same manner as the sub-pixel P contained in the pixel island 102, for the same lens 104, when the light-emitting sub-pixel (e.g., the 48th light-emitting sub-pixel 48) is damaged, the redundant sub-pixel P' (e.g., the redundant sub-pixel P' labeled 48) having the same relative position as the lens 104 can be lit to replace the damaged light-emitting sub-pixel (e.g., the 48th light-emitting sub-pixel 48) with the redundant sub-pixel P' (e.g., the redundant sub-pixel P' labeled 48). Since the redundant sub-pixel P' (e.g., the redundant sub-pixel P' labeled 48) and the damaged light-emitting sub-pixel (e.g., the 48th light-emitting sub-pixel 48) have the same relative position relative to the same lens 104, the emitted light from the two can form the same viewpoint in space after passing through the lens 104.

[0046] In some embodiments, in the above display device provided in the embodiments of the present disclosure, the design is based on the highest capability of the current Mini LED or Micro LED process, taking into account the placement height, such as Figure 5As shown, the width W of the sub-pixel P along the row direction X may be 6.5 μm-1000 μm, the length L of the sub-pixel P along the column direction Y may be 10 μm-2000 μm, and the distance S between the sub-pixels P in each row in the pixel island 102 may be 4 μm-1000 μm. Exemplarily, the width W of the sub-pixel P along the row direction X is 6.5 μm, the length L of the sub-pixel P along the column direction Y is 10 μm, and the distance S between the sub-pixels P in each row in the pixel island 102 is 4 μm.

[0047] In some embodiments, in the above display device provided by the embodiments of the present disclosure, if Figure 6 As shown, according to the process limit, the distance S' between the pixel islands P in each row may be greater than or equal to 70 μm, that is, at least 70 μm, for example, 75 μm.

[0048] The table below shows the relevant data of a column of pixel islands 102 and a corresponding lens 104. It can be seen from the table that the main lobe viewing angle formed in space by the emitted light of the pixel island 102 after passing through the corresponding lens 104 is 24.74654°. In addition, after the 24 viewpoints formed by the two columns of pixel islands 102 corresponding to a light splitting repeating unit 105 in the present disclosure are spliced, the entire viewing angle is actually about 44°.

[0050] In some embodiments, in the above display device provided by the embodiments of the present disclosure, if Figure 2 As shown, in two columns of pixel islands 102 corresponding to the same light-splitting repeating unit 105, every six pixel islands 102 arranged in sequence along the column direction Y constitute a pixel repeating unit 107; in one pixel repeating unit 107, six pixel islands 102 display three colors, and the display colors of every two adjacent pixel islands 102 arranged in sequence along the column direction Y are the same, so that the three luminous sub-pixels at the same viewpoint in one pixel repeating unit 107 have different luminous colors, thereby realizing color picture display. By way of example, in Figure 2 The first two pixel islands 102 along the column direction Y display red, the middle two pixel islands 102 display green, and the last two pixel islands 102 display blue. In some embodiments, the size of a pixel repeating unit 107 may be 702 μm*702 μm.

[0051] In some embodiments, according to the current process limit of Mini LED, a maximum of 426 pixel islands 102 can be designed along the row direction X, and a maximum of 240 pixel islands 102 can be designed along the column direction Y, so that a display screen with a width of 299.052 mm in the row direction X and a length of 168.48 mm in the column direction Y can be obtained, that is, the pixel islands 102 can be spliced ​​into a 13.51-inch display screen. By splicing 13.51 inches, a larger display panel 101 can be obtained, and combined with the lens 104, a large-viewing angle light field display can be achieved.

[0052] It should be noted that in the above display device provided by the embodiment of the present disclosure, the splicing of the main lobe viewing angle can be realized based on the medium and large size splicing panels in the related art, and the structure of the pixel island 102 contained in the display panel 101 can also be designed based on the purpose of realizing the splicing of the viewing angle. Specifically, the medium and large size splicing panels in the related art generally include sub-pixels P arranged in a matrix in rows and columns (equivalent to Figure 2 The gaps between the sub-pixels P contained in the pixel island 102 shown in the figure and the gaps between the adjacent pixel islands 102 also have unactivated sub-pixels P). At this time, the required sub-pixels P (such as Figure 2 The sub-pixels P shown in FIG. 1 are used to form the pixel island 102. In order to achieve the purpose of viewing angle stitching, when the structure of the pixel island 102 included in the display panel 101 is designed, the actual sub-pixels P of the display panel 101 are arranged as follows: Figure 2 As shown, only the sub-pixels P are made at the positions required by the design, and the rest of the positions are left blank. Both of the above methods can achieve the effect of large viewing angle light field display through viewing angle splicing.

[0053] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if these modifications and variations of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is also intended to include these modifications and variations.
