The display panel comprises a first display panel and a second display panel arranged along a first direction. In the first direction, a light shielding structure overlaps with a side surface. The light shielding structure comprises a first light shielding structure corresponding to the first display panel. In the first direction, the first light shielding structure exposes at least part of the side surface of the first display panel. The light shielding structure comprises a second light shielding structure corresponding to the second display panel. In the first direction, the second light shielding structure exposes at least part of the side surface of the second display panel. In the first direction, the first light shielding structure and the second light shielding structure at least partially do not overlap. In this way, at least part of the side surface of the first display panel exposed by the first light shielding structure is compensated by the second light shielding structure, which weakens the visual effect of the black line of the splicing area while shielding the bright line of the splicing area, thereby improving the display effect of the display module.

Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display module and a display device. Background Technology

[0002] Micro-LED display technology, with its high brightness, high contrast, low power consumption, long lifespan, and excellent transparency, is considered a core technology for realizing the next generation of ideal transparent displays. To achieve large-size transparent displays, multiple standard-sized Micro-LED transparent display units are typically spliced ​​together. However, currently, when multiple Micro-LED transparent display units are spliced ​​together, if the sides are not light-shielded, bright lines easily appear in the splicing area in bright conditions; if the sides are fully light-shielded, obvious dark lines easily appear in the splicing area in dark conditions, resulting in poor display quality. Summary of the Invention

[0003] This application provides a display module and a display device, in which at least a portion of the side surface exposed by the first light-shielding structure in the first display panel is light-shielded by the second light-shielding structure. This reduces the visual effect of the black lines in the splicing area while blocking the bright lines, thereby improving the display effect of the display module.

[0004] In a first aspect, embodiments of this application provide a display module, including: At least two display panels, each display panel including a side surface and a light-shielding structure; the display panels include a first display panel and a second display panel arranged along a first direction, wherein the light-shielding structure overlaps with the side surface along the first direction; The light-shielding structure includes a first light-shielding structure corresponding to the first display panel, and along the first direction, the first light-shielding structure exposes at least a portion of the side surface of the first display panel; The light-shielding structure includes a second light-shielding structure corresponding to the second display panel, wherein, along the first direction, the second light-shielding structure exposes at least a portion of the side surface of the second display panel; wherein... Along the first direction, the first light-shielding structure and the second light-shielding structure do not overlap at least partially.

[0005] Secondly, embodiments of this application provide a display device including the display module described in any one of the first aspects.

[0006] The display module provided in this application embodiment includes a first display panel and a second display panel spliced ​​together along a first direction. The light-shielding structure includes a first light-shielding structure and a second light-shielding structure. The first light-shielding structure is correspondingly disposed on the side surface of the first display panel, and along the first direction, the first light-shielding structure exposes at least a portion of the side surface of the first display panel, meaning the first light-shielding structure is discontinuously disposed on the side surface of the first display panel. The second light-shielding structure is correspondingly disposed on the side surface of the second display panel, and along the first direction, the second light-shielding structure exposes at least a portion of the side surface of the second display panel, meaning the second light-shielding structure is discontinuously disposed on the side surface of the second display panel. Thus, the light absorption effect of the light-shielding structure is weakened by the discontinuous first and second light-shielding structures, thereby improving the dark line phenomenon in the splicing area when the display module is in a dark state. Furthermore, along the first direction, the first light-shielding structure and the second light-shielding structure do not overlap at least partially. Therefore, at least a portion of the exposed side surface of the first light-shielding structure in the first display panel is compensated for by the non-overlapping second light-shielding structure. This improves the light leakage phenomenon in the splicing area when the display module is in a bright state by ensuring that each splicing area has a corresponding light-shielding structure for light shielding, thereby enhancing the display effect of the display module.

Detailed Implementation

[0008] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be fully described below with reference to the accompanying drawings in the embodiments of this application and through specific implementation methods. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort fall within the protection scope of this application.

[0009] Figure 1 This is a schematic diagram of the structure of a display module provided in an embodiment of this application. See also... Figure 1 The display module provided in this application embodiment includes at least two display panels 10, each display panel including a side surface S1 and a light-shielding structure 20. The display panel 10 includes a first display panel 110 and a second display panel 120 arranged along a first direction X. Along the first direction X, the light-shielding structure 20 overlaps with the side surface S1. The light-shielding structure 20 includes a first light-shielding structure 210 corresponding to the first display panel 110, which exposes at least a portion of the side surface S1 of the first display panel 110 along the first direction X. The light-shielding structure 20 also includes a second light-shielding structure 220 corresponding to the second display panel 120, which exposes at least a portion of the side surface S1 of the second display panel 120 along the first direction X. Specifically, along the first direction X, the first light-shielding structure 110 and the second light-shielding structure 120 do not overlap at least partially.

[0010] For example, such as Figure 1As shown, the display module includes at least two display panels 10, which are spliced ​​together along a first direction X. The display panels 10 are used to display images. Specifically, the display panel 10 includes a first main surface (not shown in the figure), a second main surface (not shown in the figure), and multiple side surfaces S1. The first main surface and the second main surface are arranged opposite to each other, and the side surfaces S1 connect the first main surface and the second main surface. The first main surface can be the light-emitting side surface of the display panel. The first main surface of the display panel 10 includes a display area, which includes multiple light-emitting elements 01. The multiple light-emitting elements 01 are used to emit light so that the display panel 10 can display images. The first main surface of the display panel 10 is also provided with multiple signal lines 02. The signal lines 02 can include at least one of scan signal lines, data signal lines, positive power signal lines, negative power signal lines, and reset signal lines. For example, if the signal lines 02 include scan signal lines and data signal lines, then in the display area, the multiple scan signal lines extend horizontally and are arranged vertically, and the multiple data signal lines extend vertically and are arranged horizontally. Multiple data signal lines and multiple scan signal lines are electrically connected to the light-emitting element 01, thereby providing data signals and scan signals to the light-emitting element 01. The second main surface is the non-light-emitting side surface of the display panel 10, which is used to provide various driving signals to the signal lines 02 of the first main surface to ensure the normal operation of the light-emitting element 01.

[0011] Furthermore, the side surface S1 connects the first main surface and the second main surface. The side surface S1 can be the splicing surface of the display panel 10, that is, the side surfaces S1 of two adjacent display panels 10 are spliced ​​together to form a splicing area between the spliced ​​side surfaces S1. In addition, in the prior art, the display panel is also provided with a light-shielding structure. The light-shielding structure is set on one side of the side surface. When the display module is in display mode (bright state), the light-shielding structure blocks the light emitted from the side surface of the display panel, thereby avoiding light leakage and bright lines in the splicing area. However, currently, a full-area light-shielding structure is usually provided on the side surface of each display panel to improve light leakage. When the display module is not displaying and is in dark mode, the full-area light-shielding structure has a strong light absorption effect, which will cause obvious dark lines in the splicing area, affecting the user experience.

[0012] Therefore, this application embodiment improves the arrangement of the light-shielding structure 20, thereby reducing light leakage in the display module under bright conditions and weakening dark lines in the display module under dark conditions. For example, the display panel includes a light-shielding structure 20, which partially overlaps with the side surface S1 along the first direction X. It is understood that the light-shielding structure 20 is disposed on one side of the side surface S1; for example, the light-shielding structure 20 can directly contact the side surface S1, or it can be separated from the side surface S1 by other film layers. This application does not impose any limitations on this. The light-shielding structure 20 includes a first light-shielding structure 210 and a second light-shielding structure 220. The first light-shielding structure 210 is disposed on the side surface S1 of the first display panel 110, and along the first direction X, the first light-shielding structure 210 exposes at least a portion of the side surface S1 of the first display panel 110. That is, the first light-shielding structures 210 are discontinuously disposed, with openings between different first light-shielding structures 210 or openings on the first light-shielding structures 210 that expose a portion of the side surface S1 of the first display panel 110. Similarly, the second light-shielding structure 220 is disposed on the side surface S1 of the second display panel 120, and along the first direction X, the second light-shielding structure 220 exposes at least a portion of the side surface S1 of the second display panel 120. That is, the second light-shielding structure 220 is discontinuously disposed, with openings between different second light-shielding structures 220 or openings on the second light-shielding structure 220 that expose at least a portion of the side surface S1 of the second display panel 120. Thus, by discontinuously arranging the first light-shielding structure 210 and the second light-shielding structure 220, the light absorption effect of the light-shielding structure 20 is weakened, thereby improving the dark line phenomenon in the splicing area when the display module is in a dark state. Furthermore, along the first direction X, the first light-shielding structure 210 and the second light-shielding structure 220 at least partially do not overlap, meaning that the corresponding first light-shielding structure 210 and the corresponding light-shielding structure 220 have completely staggered portions. Therefore, at least a portion of the exposed side surface of the first light-shielding structure 210 in the first display panel 110 can be compensated for by the light-shielding effect of the second light-shielding structure 220, which does not overlap with the corresponding second light-shielding structure 220. Similarly, at least a portion of the exposed side surface of the second light-shielding structure 220 in the second display panel 120 can be compensated for by the light-shielding effect of the first light-shielding structure 210, which does not overlap with the corresponding second light-shielding structure 220. Thus, in the splicing area, the side surface S1 of the first display panel 110 and the side surface S1 of the second display panel 220 are both compensated for by the corresponding first light-shielding structure 210 and / or second light-shielding structure 220, so as to avoid light leakage in the splicing area when the display module is in the bright state, resulting in bright lines and improving the display effect of the display module.

[0013] It should be noted that, Figure 1The illustration uses only the first direction X as a horizontal direction as an example, but it is not intended to limit the scope of the illustration. Those skilled in the art will understand that the first direction X can be horizontal and / or vertical. When the first direction X is vertical, at least two display panels 10 are spliced ​​together in the vertical direction; when the first direction X is both horizontal and vertical, multiple display panels 10 are spliced ​​together in both the horizontal and vertical directions.

[0014] In summary, this embodiment of the application, by setting a first light-shielding structure to expose at least a portion of the side surface of the first display panel in a first direction, and a second light-shielding structure to expose at least a portion of the side surface of the second display panel in a first direction, thereby discontinuously setting the first and second light-shielding structures at least in the splicing area, weakens the light absorption effect of the light-shielding structures in the splicing area and improves the dark line phenomenon in the splicing area when the display module is in a dark state. Furthermore, by setting the first and second light-shielding structures to at least partially not overlap along the first direction, the exposed side surface of the first light-shielding structure in the first display panel is compensated for by the light-shielding of the second light-shielding structure, which does not overlap with the corresponding first light-shielding structure. Similarly, the exposed side surface of the second light-shielding structure in the second display panel is compensated for by the light-shielding of the first light-shielding structure, which does not overlap with the corresponding second light-shielding structure. This ensures that the side surfaces of the splicing area are all shielded by the first and / or second light-shielding structures, improving the light leakage phenomenon in the splicing area when the display module is in a bright state and enhancing the display effect of the display module.

[0015] Optionally, based on the above embodiments, Figure 2 This is a partial schematic diagram of the side surface of a first display panel provided in an embodiment of this application. See also... Figure 1 and Figure 2 The first light-shielding structure 210 includes a first interval 30 that exposes the side surface S1 of the first display panel 110 along the first direction X, and the second light-shielding structure 220 at least partially overlaps with the first interval 30.

[0016] For example, such as Figure 1 and Figure 2 As shown, the first light-shielding structure 210 is also provided with a first interval 30, which can be understood as follows: Figure 2This description uses only the first interval 30 between two adjacent first light-shielding structures 210 as an example. In other embodiments, the first interval 30 may also be an opening on the first light-shielding structure 210. This application does not limit this, and those skilled in the art can set it as needed. If the area where the first interval 30 is located is not provided with a first light-shielding structure 210, then along the first direction X, the area covered by the first light-shielding structure 210 on the side surface S1 of the first display panel 110 is protected by the first light-shielding structure 210, which blocks the light emitted from the side surface S1. The area covered by the first interval 30, however, exposes the side surface S1 of the first display panel 110. Therefore, in this embodiment of the application, by setting the second light-shielding structure 220 to at least partially overlap with the first interval 30 along the first direction X, that is, by using the second light-shielding structure 220 of the second display panel 120 to block the light of the first interval 30, the light-shielding continuity of the first display panel 110 is ensured by the second light-shielding structure 220 on the basis of the discontinuous setting of the first light-shielding structure 210, the light leakage phenomenon when the display module is bright is improved, and the display effect of the display module is enhanced.

[0017] Optional, Figure 3 This is an enlarged schematic diagram of a splicing area provided in an embodiment of this application. See also... Figure 3 Along the first direction X, the overlapping area between the second light-shielding structure 220 and the first interval 30 is the first overlapping area L1, and the overlapping area between the second light-shielding structure 220 and the first light-shielding structure 210 is the second overlapping area L2. Along the first direction X, the thickness of the second light-shielding structure 220 in the first overlapping area L1 is greater than the thickness of the second light-shielding structure 220 in the second overlapping area L2.

[0018] For example, such as Figure 3 As shown, on the side surface S1 of the first display panel 110, the area where the first interval 30 is located is not provided with the first light-shielding structure 210, thus exposing part of the side surface S1. Furthermore, along the first direction X, the second light-shielding structure 220 at least partially overlaps with the first interval 30. Based on this, the overlapping area of ​​the second light-shielding structure 220 and the first interval 30 is designated as the first overlapping area L1, meaning that only the second light-shielding structure 220 is provided in the first overlapping area L1. The overlapping area of ​​the second light-shielding structure 220 and the corresponding first light-shielding structure 210 is designated as the second overlapping area L2, meaning that both the first light-shielding structure 210 and the second light-shielding structure 220 are provided in the second overlapping area L2. Along the first direction X, by setting the thickness of the second light-shielding structure 220 in the first overlapping region L1 to be greater than the thickness of the second light-shielding structure 220 in the second overlapping region L2, the thickness of the second light-shielding structure 220 along the first direction X is set to be larger in the region where the first interval 30 is located. This weakens the light absorption effect of the display module in the dark state while ensuring the light-shielding effect of the region where the first interval 30 is located in the bright state of the display module, thus ensuring the uniformity of light shielding.

[0019] It should be noted that, in one embodiment, the thickness of the second light-shielding structure 220 along the first direction X in the first overlapping region L1 can be set to d1, and the total thickness of the first light-shielding structure 210 and the second light-shielding structure 220 in the second overlapping region L2 can be set to d2, wherein |d1-d2| / d1≤20%. Specifically, in the first overlapping region L1, the thickness of the second light-shielding structure 220 along the first direction X is d1, and in the second overlapping region L2, the total thickness of the first light-shielding structure 210 and the second light-shielding structure 220 in the first direction X is d2. When there is no gap between the first light-shielding structure 210 and the second light-shielding structure 220, the total thickness d2 is the distance between the side surface of the first light-shielding structure 210 near the side surface S1 of the first display panel 110 and the side surface of the second light-shielding structure 220 near the side surface S1 of the second display panel 120. When there is a gap between the first light-shielding structure 210 and the second light-shielding structure 220, the total thickness d2 is the sum of the thickness of the first light-shielding structure 210 and the thickness of the second light-shielding structure 220. By setting |d1-d2| / d1≤20%, the thickness of the second light-shielding structure 220 in the first overlapping area L1 is approximately the same as the sum of the thicknesses of the first light-shielding structure 210 and the second light-shielding structure 220 in the second overlapping area L2, thereby ensuring that the light-shielding effect is approximately the same at each position in the splicing area when the display module is in the bright state.

[0020] Optional, see below Figure 1 and Figure 2 The light-shielding structure 20 includes a plurality of first light-shielding structures 210. The first interval 30 includes a first sub-interval 310. Along the second direction Y, the first sub-interval 310 is located between two adjacent first light-shielding structures 210, and the first sub-interval 310 extends along the third direction Z. The second direction Y is parallel to the plane where the display panel 10 is located and intersects with the first direction X. The third direction Z is the thickness direction of the display panel 10.

[0021] For example, such as Figure 1 and Figure 2 As shown, the first interval 30 includes a first sub-interval 310, and the side surface S1 of the first display panel 110 includes a plurality of first light-shielding structures 210. The first sub-interval 310 is located between two adjacent first light-shielding structures 210, and the first sub-interval 310 extends along the thickness direction (third direction Z) of the display panel. In one embodiment, along the third direction Z, the first sub-interval 310 penetrates the light-shielding structure 20, thereby dividing the light-shielding structure 20 into a plurality of independent first light-shielding structures 210, so that the plurality of first light-shielding structures 210 are discontinuously arranged in the second direction Y, weakening the light absorption effect of the display module in the splicing area when it is in a dark state, and improving the user experience.

[0022] Optional, Figure 4 This is a partial schematic diagram of a first display panel provided in an embodiment of this application. See also... Figure 4 The display panel 10 also includes a plurality of light-emitting element groups 03 located on the first main surface S2, each light-emitting element group 03 including at least two light-emitting elements 01. Along the second direction Y, the spacing between two adjacent light-emitting element groups 03 is D1, the length of the first light-shielding structure 210 or the second light-shielding structure 220 is D2, and the length of the first sub-space 310 is D3, wherein D2≥D1 / 2, and / or, D3≤D1 / 2.

[0023] For example, such as Figure 4 In the illustrated embodiment, the display panel 10 further includes a first main surface S2, which is the light-emitting side surface of the display panel 10. Multiple light-emitting element groups 03 are also disposed on the first main surface S2, arranged in an array. Each light-emitting element group 03 includes at least two light-emitting elements 01, which can be two light-emitting elements 01 with different emitting colors. The distance between two adjacent light-emitting element groups 03 along the second direction Y is D1. The distance between two adjacent light-emitting element groups 03 along the second direction Y can be understood as the distance between light-emitting elements 01 with the same emitting color in two adjacent light-emitting element groups 03 along the second direction Y. Based on this, by setting the length D2 of the first light-shielding structure 210 or the second light-shielding structure 220 along the second direction Y to be greater than or equal to half the distance D1 between two adjacent light-emitting element groups 03 along the second direction Y, the length of the first light-shielding structure 210 or the second light-shielding structure 220 along the second direction Y is ensured to be sufficiently long, guaranteeing the light-shielding effect of the first light-shielding structure 210 on the side surface S1. And / or, the length D3 of the first sub-space 310 along the second direction Y is set to be less than or equal to half of the spacing D1 between two adjacent light-emitting element groups 03 along the second direction Y, so as to avoid the first sub-space 310 being too long in the second direction Y, which would prevent it from being blocked by the second light-blocking structure 220 located on the second display panel 120, thus affecting the light-blocking effect of the side surface of the first display panel.

[0024] Optionally, in yet another embodiment, Figure 5 This is a partial schematic diagram of the side surface of another first display panel provided in an embodiment of this application. See also... Figure 1 and Figure 5 The first interval 30 also includes a second sub-interval 320. The second sub-interval 320 is disposed on the first light-shielding structure 210 and extends through the first light-shielding structure 210 along the first direction X.

[0025] For example, such as Figure 5In the illustrated embodiment, the first interval 30 further includes a second sub-interval 320, wherein the second sub-interval 320 can be an opening provided on the first light-shielding structure 210. Specifically, multiple slotted areas can be provided on the entire first light-shielding structure 210, and the second sub-interval 320 is obtained by removing the first light-shielding structure in the multiple slotted areas, that is, the second sub-interval 320 penetrates the first light-shielding structure 210 along the first direction X. In this way, the first light-shielding structure 210 can be set as a discontinuous structure in the thickness direction (i.e., the third direction Z) of the display panel 10, and / or in the second direction Y, to weaken the light absorption effect of the light-shielding structure 20, thereby improving the dark line phenomenon in the splicing area when the display module is in a dark state. It should be noted that, along the first direction X, the second light-shielding structure 220 and the second sub-space 320 at least partially overlap. The second light-shielding structure 220 provides light-shielding compensation for the side surface S1 of the first display panel 110 exposed by the second sub-space 320, thereby preventing light leakage in the splicing area when the display module is in the bright state and improving the display effect of the display module.

[0026] Optional, see below Figure 5 Multiple second sub-spaces 320 are arranged along a second direction Y, and / or multiple second sub-spaces 320 are arranged along a third direction Z. Multiple second sub-spaces 320 extend along the second direction Y.

[0027] The second direction Y is parallel to the plane where the display panel 10 is located and intersects with the first direction X. The third direction Z is the thickness direction of the display panel 10.

[0028] Specifically, such as Figure 5 As shown, multiple second sub-spaces 320 are arranged along the second direction Y, thereby discontinuously setting the first light-shielding structure 210 in the second direction Y, and / or, multiple second sub-spaces 320 are arranged along the third direction Z, thereby discontinuously setting the first light-shielding structure 210 in the third direction Z, to weaken the light absorption effect of the first light-shielding structure 210, thereby improving the dark line phenomenon in the splicing area when the display module is in a dark state. It is understood that the second sub-spaces 320 can extend along the second direction Y or along the third direction Z. This application restricts the extension direction of the second sub-spaces 320, and those skilled in the art can set it as needed.

[0029] Optional, Figure 6 This is a schematic diagram illustrating the misaligned unfolding of a splicing area provided in an embodiment of this application. See also... Figure 6The light-shielding structure 20 includes a plurality of first light-shielding structures 210 and a plurality of second light-shielding structures 220. The second light-shielding structure 220 includes a second interval 40 exposing the side surface S2 of the second display panel 120. Along the first direction X, the first light-shielding structures 210 and the second interval 40 at least partially overlap. The first interval 30 includes a first sub-interval 310, and the second interval 40 includes a third sub-interval 430. Different first light-shielding structures 210 are independently arranged through the first sub-interval 310, and different second light-shielding structures 220 are independently arranged through the third sub-interval 430. Along the second direction Y, the first light-shielding structures 210 and the second light-shielding structures 220 have the same extension length, and the first sub-interval 310 and the third sub-interval 430 have the same width.

[0030] For example, such as Figure 6 In the illustrated embodiment, to better explain the relative positional relationship between the first light-shielding structure 210 and the second light-shielding structure, the splicing areas of the first display panel 110 and the second display panel 120 are staggered for explanation. Those skilled in the art will readily understand that in actual products, the side surfaces S1 of the first display panel 110 and the second display panel 120 are positioned opposite each other. Specifically, the second light-shielding structure 220 is further provided with a second interval 40. The second interval 40 includes a third sub-interval 430. The side surface S1 of the second display panel 120 includes multiple second light-shielding structures 220, and the third sub-interval 430 is located between two adjacent second light-shielding structures 220, extending along the thickness direction (third direction Z) of the display panel. In one embodiment, along the third direction Z, a third sub-spacement 430 penetrates the light-shielding structure 20, thereby dividing the light-shielding structure 20 into multiple independent second light-shielding structures 220. This ensures that the multiple second light-shielding structures 220 are discontinuously arranged in the second direction Y, weakening the light absorption effect of the display module in the splicing area when it is in a dark state and improving the user experience. Similarly, the side surface S1 of the first display panel 110 is provided with multiple first light-shielding structures 210, and a first sub-spacement 310 is provided between different first light-shielding structures 210, so that the multiple first light-shielding structures 210 are discontinuously arranged in the second direction Y. Based on this, in this embodiment of the application, the first light-shielding structure 210 and the second light-shielding structure 220 are set to have the same extension length along the second direction Y, and the first sub-space 310 and the third sub-space 430 have the same width. Thus, the length and spacing of the first light-shielding structure 210 in the first display panel 110 are set to be the same as the length and spacing of the second light-shielding structure 220 in the second display panel 120. In this way, when the first display panel 110 and the second display panel 120 are spliced, it is only necessary to misalign the first light-shielding structure 210 and the second light-shielding structure 220 in the first direction X, so as to ensure that the complementary method of the first light-shielding structure 210 and the second light-shielding structure 220 is simple.

[0031] It should be noted that the above embodiments are only exemplified by taking the first light-shielding structure 210 in the first display panel 101 as having the same length and spacing along the second direction Y, but this is not a limitation. In other embodiments, the first light-shielding structure 210 includes a first sub-light-shielding structure that at least partially overlaps with the light-emitting element group 03 along the first direction X, and a second sub-light-shielding structure that is completely offset from the light-emitting element group 03 along the first direction X. Since the lateral light emission of the area corresponding to the light-emitting element group 03 is relatively large, the size of the first sub-light-shielding structure is set to be larger than the size of the second sub-light-shielding structure, so as to better block the lateral light emission of the light-emitting element group 03 through the first sub-light-shielding structure. Wherein, the size of the first sub-light-shielding structure being larger than the size of the second sub-light-shielding structure can be understood as the length of the first sub-light-shielding structure along the second direction Y being greater than the length of the second sub-light-shielding structure along the second direction Y, and / or the width of the first sub-light-shielding structure along the third direction Z being greater than the width of the second sub-light-shielding structure along the third direction Z.

[0032] It should also be noted that the above embodiments are only exemplified by assuming that the light-shielding structures 20 in the display panel 10 are of equal length and equally spaced. In other embodiments, the light-shielding structures 20 can be arranged at non-equal intervals and each light-shielding structure 20 has a different length. This can effectively destroy the original periodic spatial frequency characteristics of the splicing area. Specifically, if the light-shielding structures 20 are arranged in a regular pattern of length and equal spacing, the repeating patterns on both sides of the splicing area are likely to form a recognizable phase difference or periodic abrupt change in the human eye, causing the boundary of the splicing area to stand out due to visual contrast. Furthermore, by designing with differentiated lengths and non-uniform spacing, the distribution of the light-shielding structures 20 near the splicing area exhibits random or gradual characteristics, making the optical transition at the junction of adjacent display panels 10 smoother, reducing the sensitivity of the human eye to periodic defects, thereby significantly weakening the perceptibility of the splicing seam and improving the overall visual consistency of the spliced ​​display panel.

[0033] Optionally, based on the above embodiments, Figure 7 This is a partial schematic diagram of the side surface of another first display panel provided in an embodiment of this application. Figure 8 This is a schematic diagram illustrating the misalignment and unfolding of another splicing region provided in an embodiment of this application. See also... Figure 7 and Figure 8 The light-shielding structure 20 includes a plurality of first light-shielding structures 210, and the shapes of the vertical projections of at least two first light-shielding structures 210 onto the plane containing the side surface S1 are complementary. And / or, the light-shielding structure 20 includes a plurality of first light-shielding structures 210 and a plurality of second light-shielding structures 220, the shapes of the vertical projections of the first light-shielding structures 210 onto the plane containing the side surface S1 are complementary to the shapes of the vertical projections of the corresponding second light-shielding structures 220 onto the plane containing the side surface S1.

[0034] For example, such as Figure 7 As shown, the light-shielding structure 20 includes multiple first light-shielding structures 210, with first sub-spacers 310 separating the different first light-shielding structures 210. Furthermore, second sub-spacers 320 are provided on the first light-shielding structures 210 to pattern them. Based on this, on the side surface S1 of the first display panel 110, there are two first light-shielding structures 210 whose vertical projections on the plane of the side surface S1 are complementary in shape. The complementary shape of the vertical projections can be understood as follows: the vertical projections of two first light-shielding structures 210 on the plane of the side surface S1 do not overlap, but when the two vertical projections are moved so that they completely overlap, their shapes become complementary. That is, there are two first light-blocking structures 210 that are spatially offset, but their shapes are complementary after being moved. This achieves complementary differences in the shapes of the first light-blocking structures 210 at different positions, further weakening the light-absorbing effect of the first light-blocking structures 210. And / or, as... Figure 8 As shown, the first light-shielding structure 210 is located on the side surface S1 of the first display panel 110, and the second light-shielding structure 220 is located on the side surface S1 of the second display panel 120. The second light-shielding structure 220 corresponding to the first light-shielding structure 210, i.e., along the first direction X, is at least partially non-overlapping with the first light-shielding structure 210 and the second light-shielding structure 220. Based on the above, the vertical projection of the first light-shielding structure 210 onto the plane of the side surface S1 is complementary in shape to the vertical projection of the corresponding second light-shielding structure 220 onto the plane of the side surface S1. That is, the corresponding first light-shielding structure 210 and the second light-shielding structure 220 are at least partially offset in space, but their shapes are complementary after complete overlap. This ensures that the side surface of the first display panel 110 exposed through the second sub-space 320 of the first light-shielding structure 210 is covered by a corresponding second light-shielding structure 220 for complementary light shielding, improving light leakage in the splicing area when the display module is in bright state and enhancing the display effect of the display module.

[0035] It should be noted that, Figure 7 The example described herein is exemplified by a first light-shielding structure 210 comprising a plurality of light-shielding structure portions 2101, wherein the plurality of light-shielding structure portions 2101 extend along a second direction Y and are spaced apart along a third direction Z. In two instances of first light-shielding structures 210, the shape of the light-shielding structure portions 2101 of one first light-shielding structure 210 is complementary to the shape of the spacing of the portions of the other first light-shielding structure 210. However, this is not a limitation. In other embodiments, Figure 9 This is a partial schematic diagram of the side surface of another first display panel provided in an embodiment of this application. See also... Figure 9The first light-shielding structure 210 may further include a plurality of first light-shielding areas S11 and a plurality of first light-transmitting areas S12, wherein the plurality of first light-shielding areas S11 are interconnected and the plurality of first light-transmitting areas S12 are in complementary contact. In the existence of two first light-shielding structures 210, the shape of the first light-shielding area S11 of one first light-shielding structure 210 is complementary to the shape of the first light-transmitting area S12 of the other first light-shielding structure 210.

[0036] It should also be noted that, Figure 8 The example described herein is exemplified by a first light-shielding structure 210 comprising a plurality of first light-shielding structure portions 2101, and a second light-shielding structure 220 comprising a plurality of second light-shielding structure portions 2201, wherein both the plurality of first light-shielding structure portions 2101 and the plurality of second light-shielding structure portions 2201 extend along a second direction Y and are spaced apart along a third direction Z. An example is given where the shape of the first light-shielding structure portions 2101 in the first light-shielding structure 210 and the shape of the spacing between the second light-shielding structure portions 2201 are complementary, but this is not a limitation. In other embodiments, Figure 10 This is a partial schematic diagram of the side surface of another first display panel provided in an embodiment of this application. See also... Figure 10 The first light-shielding structure 210 may further include multiple first light-shielding areas S11 and multiple first light-transmitting areas S12, with the multiple first light-shielding areas S11 interconnected and the multiple first light-transmitting areas S12 in complementary contact. The second light-shielding structure 220 may further include multiple second light-shielding areas S13 and multiple second light-transmitting areas S14, with the multiple second light-shielding areas S13 interconnected and the multiple first light-transmitting areas S14 in complementary contact. In the corresponding first light-shielding structure 210 and second light-shielding structure 220, the shape of the first light-shielding area S11 is complementary to the shape of the second light-transmitting area S14.

[0037] Optional, Figure 11 yes Figure 1 A schematic diagram of a cross-section along the A-A' direction. See also... Figure 11 The display panel 10 also includes a substrate 101, a light-transmitting layer 102, a cover plate 103, and a plurality of light-emitting element groups 03 located on one side of the substrate 101. The light-transmitting layer 102 covers the light-emitting element groups 03, and the cover plate 103 is disposed on the side of the light-transmitting layer 102 away from the substrate 101. Along the first direction X, the light-shielding structure 20 overlaps with the light-transmitting layer 102 at least.

[0038] For example, such as Figure 11In the illustrated embodiment, the display panel 10 further includes a substrate 101, a light-transmitting layer 102, a cover plate 103, and multiple light-emitting element groups 03 located on one side of the substrate 101. The substrate 101 provides support for the film layer disposed thereon. A driving circuit may be disposed in the substrate 101 to provide various driving signals to the multiple light-emitting element groups 03 disposed on one side of the substrate 101, ensuring the normal operation of the light-emitting element groups 03. The light-transmitting layer 102 covers the light-emitting element groups 03, serving as an encapsulation for them. The cover plate 103 is disposed on the side of the light-transmitting layer 102 away from the substrate 101 and can be a glass cover plate, protecting the display panel from external environmental influences. Since the light emitted by the light-emitting element group 03 is refracted through the light-transmitting layer 102 and then emitted from the side surface, this embodiment of the application sets that the light-shielding structure 20 overlaps with the light-transmitting layer 102 at least along the first direction X, so as to block the light emitted from the side surface of the light-transmitting layer 102 through the light-shielding structure 20, and ensure the light-shielding effect of the light-shielding structure 20 on the side surface of the display panel 10.

[0039] It should be noted that, in one embodiment, see below. Figure 11 Along the first direction X, the light-shielding structure 20 covers the substrate 101, the light-transmitting layer 102, and the cover plate 103. By completely covering the entire side surface of the display panel 10 along the third direction Z, the light-shielding structure 20 further ensures the light-shielding effect of the light-shielding structure 20 on the side surface of the display panel 10.

[0040] In yet another embodiment, Figure 12 yes Figure 1 Another schematic diagram of a cross-section along the A-A' direction. See also... Figure 12 The display panel 10 further includes a substrate 101, a light-transmitting layer 102 located on one side of the substrate 101, and a plurality of light-emitting element groups 03, the light-transmitting layer 102 covering the light-emitting element groups 03. The display panel 10 also includes a deflection layer 50, which is located on the side surface S1 and along the first direction X, the deflection layer 50 is located on the side of the light-shielding structure 20 near the side surface S1. The refractive index of the deflection layer 50 is less than the refractive index of the light-transmitting layer 102, and along the first direction X, the deflection layer 50 at least covers the light-transmitting layer 102.

[0041] For example, such as Figure 12In the illustrated embodiment, a deflection layer 50 is further provided on the side surface S1 of the display panel 10. The deflection layer 50 is located on the side of the light-shielding structure 20 near the side surface S1, that is, the deflection layer 50 is in direct contact with the side surface S1, and the light-shielding structure 20 and the side surface S1 are separated by the deflection layer 50. Because the wide-viewing-angle light emitted from the side surface S1 is easily emitted into the positive viewing angle in an approximately perpendicular direction in the splicing area, it will not be absorbed by the light-shielding structure 20. Therefore, in this embodiment, a deflection layer 50 is provided on the side of the light-shielding structure 20 near the side surface S1. The refractive index of the deflection layer 50 is less than the refractive index of the light-transmitting layer 102, and along the first direction X, the deflection layer 50 at least covers the light-transmitting layer 102. Thus, when the wide-viewing-angle light emitted by the light-emitting element group 03 is emitted from the side surface S1 corresponding to the light-transmitting layer 102, it will first pass through the deflection layer 50. The refractive index of the deflection layer 50 is less than that of the light-transmitting layer 102. Therefore, the light will be deflected downward in the deflection layer 50, so that the light shines on the light-shielding structure 20 instead of being emitted from the front viewing angle. This further improves the light leakage phenomenon in the bright state of the display module and enhances the display effect.

[0042] Optionally, in yet another embodiment, Figure 13 This is a schematic diagram of another display module provided in an embodiment of this application. See also... Figure 13 The display module includes at least four display panels 10, which are spliced ​​together to form multiple splicing areas MM. The multiple splicing areas MM include a first splicing area MM1 and a second splicing area MM2. The extension direction of the first splicing area MM1 intersects with the extension direction of the second splicing area MM2.

[0043] Specifically, such as Figure 13 In the illustrated embodiment, the first direction X can be either horizontal or vertical. Then, of the at least four display panels 10, at least two display panels 10 are spliced ​​together horizontally, forming a splicing area MM that is the first splicing area MM1, which extends vertically. At least two display panels 10 are spliced ​​together vertically, forming a splicing area MM that is the second splicing area MM2, which extends horizontally, meaning the extension direction of the first splicing area MM1 intersects with the extension direction of the second splicing area MM2.

[0044] Optional, see below Figure 13 The side surface S1 also includes a bonding side surface S15. The display panel 10 also includes a display area AA and a non-display area BB, with the non-display area BB surrounding a portion of the display area AA and disposed on the bonding side surface S15. The portion of the light-shielding structure 20 located on the bonding side surface S15 is an integral structure, or the portion of the light-shielding structure 20 located on the bonding side surface S15 is a distributed structure.

[0045] For details, see Figure 13 The display panel 10 also includes a display area AA and a non-display area BB. The display area AA is used to display the image of the display module, and the non-display area BB is equipped with a driver chip to provide various driving signals for the image display of the display area AA. Based on the above, the side surface S1 also includes a bonding side surface S15. The non-display area BB is located on the bonding side surface S15, meaning the bonding side surface S15 and the side surface S1 of the splicing area MM are located on different sides of the display panel 10. Since the bonding side surface S15 is connected to the non-display area BB and is located at the overall edge of the display module, the light-shielding requirement for the bonding side surface S15 is lower than that for the side surface of the splicing area MM. Therefore, the portion of the light-shielding structure 20 located on the bonding side surface S15 can be an integral structure, meaning the light-shielding structure 20 is integrally formed on the bonding side surface S15, or the portion of the light-shielding structure 20 located on the bonding side surface S15 can be a distributed structure, meaning there are intervals between different light-shielding structure portions. This application does not limit this, and those skilled in the art can set it as needed.

[0046] Optional, Figure 14 yes Figure 13 A schematic diagram of a cross-section along the B-B' direction, see [reference]. Figure 14 The display panel 10 also includes a substrate 101, a light-transmitting layer 102, a cover plate 103, and multiple light-emitting element groups 03 located on one side of the substrate 101. The light-transmitting layer 102 covers the light-emitting element groups 03, and the cover plate 103 is disposed on the side of the light-transmitting layer 102 away from the light-emitting element groups 03. The light-shielding structure 20 is offset from the substrate 101 along a direction perpendicular to the plane of the bonding side surface S15. Specifically, as shown... Figure 14 As shown, since the non-display area BB is located on the bonding side surface S15, the driving chip located in the non-display area BB provides driving signals to the light-emitting element group 03 of the display area AA through the bonding side surface S15. The driving circuit is disposed in the substrate 101. Therefore, by setting the light-shielding structure 20 to be staggered from the substrate 101 along the direction perpendicular to the plane where the bonding side surface S15 is located, the light-shielding structure 20 is avoided from affecting the signal transmission between the non-display area BB and the display area AA.
