[0102] In electronic blackboard splicing display products, multiple display modules are typically spliced together to form a large electronic blackboard. While these modules can display both the same and different content, they lack interaction between the modules. Furthermore, the modules are not integrated, so it's impossible to ensure they are aligned horizontally or vertically, resulting in large gaps between the electronic blackboards.

[0103] In order to solve at least one of the above technical problems, the first aspect of the embodiment of the present disclosure proposes a splicing display module, which includes: a plurality of display modules spliced together, the display module having a splicing side; the display module includes a back plate, a display panel, a cover plate and a first fixing member; the display panel and the cover plate are arranged on the back plate in a direction away from the back plate; wherein, for one display module, the first fixing member is located on the splicing side of the display module and is arranged on the side of the cover plate facing the back plate; one end of the first fixing member is fixed to the cover plate, and the other end is fixed relative to the back plate; for any two spliced display modules, the cover plates of the two are in contact at the edge of the splicing side. The splicing display module disclosed in the present disclosure can well splice the individual display modules together and reduce the seam between adjacent display modules on the splicing side.

[0104] The display module of the embodiment of the present disclosure can be applied to an electronic blackboard, and multiple display modules can be spliced together to form a large electronic blackboard.

[0105] Figure 1a A schematic structural diagram of a spliced display module provided by the present disclosure; Figure 1b for Figure 1aThe structure diagram of the spliced display module shown is after omitting the cover plate and display panel; Figure 1c for Figure 1a A cross-sectional view of an example of a spliced display module; Figure 1d for Figure 1a A cross-sectional view of another example of a spliced display module is shown. Figure 1c and Figure 1d The splicing cross-sectional view shown is Figure 1a The cross-sections are cut along AA, BB, CC and DD directions respectively, and then the cross-sectional views of each cross-section are spliced together to obtain a spliced cross-sectional view.

[0106] In such Figures 1a to 1c In the example, the spliced display module includes: a plurality of display modules 1 spliced together, the display module 1 having a splicing side S; the display module 1 includes a back plate 10, a display panel 20, a cover plate 30 and a first fixing member 40; the display panel 20 ( Figures 1a to 1c The first fixing member 40 is located on the splicing side S of the display module and is arranged on the side of the cover plate 30 facing the back plate 10; one end of the first fixing member 40 is fixed to the cover plate 30, and the other end is fixed to the back plate 10; for any two spliced display modules 1, the cover plates 30 of the two are in contact at the edges of the splicing side S.

[0107] Figure 2 Schematic diagram of the structure of the first fixing member 40 of the splicing display module provided by the present disclosure. Figure 2 As shown, the first fixing member 40 includes a first fixing component 41 and a second fixing component 42, the first fixing component 41 includes a first connecting portion 411, a second connecting portion 412, and a third connecting portion 413 connecting the first connecting portion 411 and the second connecting portion 412; the second fixing component 42 is located on the side of the third connecting portion 413 away from the display panel 20; the first connecting portion 411 is fixedly connected to the cover plate 30; the third connecting portion 413 is fixedly connected to the second fixing component 42; the second connecting portion 412 is located between the back plate 10 and the second fixing component 42, and the three are fixedly connected.

[0108] There are various ways of fixing the connection between the third connection part 413 and the second fixing component 42, between the second connection part 412, the back panel 10 and the second fixing component 42, and between the first connection part 411 and the cover plate 30. The following examples illustrate the ways of fixing the connection between the third connection part 413 and the second fixing component 42, between the second connection part 412, the back panel 10 and the second fixing component 42, and between the first connection part 411 and the cover plate 30. It should be understood that the examples described here are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure.

[0109] It should be noted that the term "fixed" or "fixedly connected" between structures in this disclosure can be understood as a connection method in which the structures are fixed to each other and do not move relative to each other. In other words, during actual use after the module is assembled, the fixedly connected structures will not move relative to each other. However, during the actual assembly or maintenance of the module, the fixedly connected structures can move relative to each other, allowing for disassembly.

[0110] Specifically, the first connection portion 411 and the cover plate 30 may be fixedly connected via an adhesive layer. The adhesive layer may be made of, but is not limited to, foam and may also be made of other materials having an adhesive property.

[0111] The second connection portion 412, the back plate 10, and the second fixing assembly 42 are fixedly connected by a first fastener 43. The first fastener 43 can be a screw, and the second connection portion 412, the back plate 10, and the second fixing assembly 42 have threads corresponding to the screw, and the second connection portion 412, the back plate 10, and the second fixing assembly 42 are fixedly connected together by the screw.

[0112] The third connection portion 413 is fixedly connected to the second fixing assembly 42 via a second fastener 44. The second fastener 44 may be a screw, and a thread corresponding to the screw is provided at a corresponding position on the second fixing assembly 42, and the third connection portion 413 is fixedly connected to the second fixing assembly 42 via the screw.

[0113] Through the above-mentioned fixed connection method, the third connection part 413 and the second fixing component 42, the second connection part 412, the back panel 10 and the second fixing component 42, and the first connection part 411 and the cover plate 30 can be disassembled during the application and maintenance stage, thereby facilitating subsequent maintenance.

[0114] Figure 3 The present disclosure provides a schematic diagram of the structure of the second fixing member of the splicing display module. In some examples, such as Figure 1a As shown, the display module 1 further has a non-joined side S'. Figure 1c and Figure 1d for Figure 1a The cross-section is made along the AA, BB, CC and DD directions, and the cross-section view is taken on the non-joined side S'. Figure 1c or Figure 1d As shown, the display module 1 has a second fixing member 50 on the non-joining side S′. Figure 3 Indicated Figure 1c or Figure 1d The enlarged structure of the second fixing member 50 in the non-joined side S' is as follows: Figure 3As shown, the second fixing member 50 includes a third fixing component 51 and a fourth fixing component 52. The third fixing component 51 includes a first fixing structure 511 and a second fixing structure 512 connected to each other; the first fixing structure 511 and the second fixing structure 512 can be an integral structure. The first fixing structure 511 is located on the side of the cover plate 30 facing the back plate 10, and one end is fixed to the cover plate 30 and the other end is fixed to the back plate 10; the second fixing structure 512 protrudes from the cover plate 30 and has a first receiving groove 5121 facing the display area. A first light bar 5122 is arranged in the first receiving groove 5121. The light-emitting element 5123 in the first light bar 5122 protrudes from the cover plate 30 to facilitate the light-emitting element 5123 to emit light. The fourth fixing assembly 52 includes a fourth connecting portion 521, a fifth connecting portion 522, and a sixth connecting portion 523 connecting the fourth and fifth connecting portions 521 and 522. The third fixing assembly 51 is located on the side of the sixth connecting portion 523 facing away from the display panel 20. The fourth connecting portion 521 is fixedly connected to the cover plate 30; the sixth connecting portion 523 is fixedly connected to the third fixing assembly 51. The fifth connecting portion 522 is located between the back plate 10 and the first fixing structure 511 of the third fixing assembly 51, and the three are fixedly connected. The third and fourth fixing assemblies 51 and 52 provide support for the cover plate 30, improving the reliability of the display module.

[0115] It should be noted that the first light bar 5122 is mainly used to implement the touch function. The first light bar 5122 includes a plurality of light emitting elements 5123, and the light emitting elements 5123 can be infrared light emitting elements.

[0116] Alternatively, as Figure 1c As shown, the display module 1 has a second fixing member 50 on the non-joining side S′.

[0117] Alternatively, as Figure 1d As shown, the display module 1 has second fixing members 50 on two opposite non-joint sides S′ in the extending direction of the joint side S.

[0118] Figure 4 for Figure 1a The spliced display module is shown as a partially enlarged schematic diagram in the M area. In some examples, such as Figure 4As shown, the light-emitting element 5123 has a light-emitting area. In the example disclosed in the present disclosure, the light-emitting element 5123 is an infrared light-emitting element, and the effective light-emitting area is 80°. In any two adjacent display modules, the orthographic projections of the two adjacent first fixing members 40 on the first plane and the orthographic projections of the two light-emitting areas of the two adjacent light-emitting elements 5123 on the first plane do not overlap; wherein, the first plane is the plane where the back panel 10 is located. Through this setting method, the first fixing member 40 can be prevented from blocking the light emitted by the light-emitting element 5123 on the splicing side S, thereby affecting the splicing effect.

[0119] In some examples, to avoid touch failure, in any two adjacent display modules 1, the distance between the two adjacent first light bars 5122 is less than 16 mm. More specifically, the first light bar 5122 includes a driving circuit board and a light-emitting element 5123 arranged on the driving circuit board. In any two adjacent display modules 1, the distance between the driving circuit boards of the two adjacent first light bars 5122 is less than 16 mm, for example, 1 mm, 2 mm, 3.5 mm, 5 mm, 6 mm, 7.8 mm, 10 mm, 12 mm, etc. The driving circuit board can be a PCB (Printed Circuit Board). By reasonably setting the distance between the driving circuit boards of the first light bars 5122 of adjacent display modules 1, the occurrence of invalid touch areas, that is, the occurrence of areas not covered by the light emitted by the light-emitting element 5123, can be effectively avoided.

[0120] In some examples, in order to avoid touch failure, in any two adjacent display modules 1, the distance between the light-emitting elements 5123 of two adjacent first light bars 5122 is less than 20 mm, for example, 1 mm, 2 mm, 3.5 mm, 5 mm, 6 mm, 7.8 mm, 10 mm, 12 mm, 15 mm, 16 mm, 18 mm, etc.

[0121] In some examples, such as Figure 3 and Figure 4 As shown, a first filter strip 5124 is fixed at the opening of the first receiving groove 5121. In any two adjacent display modules 1, there is a seam between the two adjacent first filter strips 5124. To prevent the seam from affecting the display failure of the display module, in any two adjacent display modules 1, with respect to the seam between the two adjacent first filter strips 5124 and the two adjacent light-emitting elements 5123, the light emitted by the two light-emitting elements 5123 does not pass through the seam between the two first filter strips 5124.

[0122] Figure 5A partial schematic diagram of a spliced display module provided by the present disclosure. Figure 6 Schematic diagram of the structure of the first lock buckle and the first fixing block provided by the present disclosure. In some examples, such as Figure 5 and Figure 6 As shown, any two adjacent display modules 1 have a first lock buckle 60 fixed on the splicing side S on the back panel 10 of one, and a first positioning block 70 corresponding to the first lock buckle 60 fixed on the splicing side S on the back panel 10 of the other, and the first lock buckle 60 and the first positioning block 70 are detachably connected.

[0123] In some examples, the first locking catch 60 includes: a second positioning block 61 and a connecting rod 62; wherein the second positioning block 61 is fixed to the back panel 10 and is arranged corresponding to the first positioning block 70; the connecting rod 62 is an open-loop structure, having a first end 621 and a second end 622, both of which are rotatably connected to the second positioning block 61, and the connecting rod 62 can be rotated to the side of the first positioning block 70 and fixedly connected to the first positioning block 70. The first positioning block 70 has a first groove 71 on the side facing away from the first locking catch 60, and the connecting rod 62 also includes a middle portion 623 connecting the first end 621 and the second end. In the spliced state, the middle portion 623 of the connecting rod 62 of the first locking catch 60 is stuck in the first groove 71, thereby further reducing the splicing gap between any two adjacent display modules.

[0124] In some examples, such as Figure 5 and Figure 6 As shown, the first locking buckle 60 includes a second positioning block 61, a connecting rod 62, and a handle 63. The second positioning block 61 is fixed to the back panel 10 and corresponds to the first positioning block 70. The handle 63 is rotatably connected to the second positioning block 61 at the end closest to the first positioning block 70. The connecting rod 62 is an open-loop structure, having a first end 621, a middle portion 623, and a second end 622, which are connected in sequence. The first end 621 and the second end 622 are rotatably connected to the handle 63, and the connecting rod 62 can be rotated toward the first positioning block 70 and fixedly connected to the first positioning block 70. In the spliced state, the middle portion 623 of the connecting rod 62 of the first locking buckle 60 is engaged in the first groove 71. The end of the handle, which is farther from the first positioning block 70, presses down onto the back panel 10, forming a self-locking structure with the connecting rod engaged in the first groove 71. This improves the locking strength of the two adjacent display modules and enhances the reliability of the entire spliced display module.

[0125] In some examples, such as Figure 6 As shown, the first lock buckle 60 further includes a rotating shaft 64 , and the first end 621 of the connecting rod 62 and the second end 622 of the connecting rod 62 are rotatably connected to the handle 63 via the rotating shaft 64 passing through the handle 63 .

[0126] In some examples, such as Figure 6As shown, the first lock catch 60 further includes a third fastener 65, a fourth fastener 66, a fifth fastener 67, and a sixth fastener 68. The third fastener 65, the fourth fastener 66, the fifth fastener 67, and the sixth fastener 68 can all be nuts. The rotating shaft 64 of the first lock catch 60 has a first end 641 and a second end 642. The first end 621 and the second end 622 of the connecting rod 62 of the first lock catch 60 are both threaded. The first end 621 of the connecting rod 62 passes through the first end 641 of the rotating shaft 64. The third fastener 65 and the fourth fastener 66 are located on either side of the first end 641 of the rotating shaft 64 and are threadedly connected to the first end 621 of the connecting rod 62. The second end 622 of the connecting rod 62 passes through the second end 642 of the rotating shaft 64. The fifth fastener 67 and the sixth fastener 68 are located on either side of the second end 642 of the rotating shaft 64 and are threadedly connected to the second end 622 of the connecting rod 62.

[0127] In the spliced state, the connecting rod 62 can be prevented from moving by tightening the fifth fastener 67 and the sixth fastener 68 on both sides of the second end 642 of the rotating shaft 64, and tightening the third fastener 65 and the fourth fastener 66 on both sides of the first end 641 of the rotating shaft 64.

[0128] In the non-spliced state, the first end 621 of the connecting rod 62 has a first side 624 facing the first positioning block 70, and the second end 622 of the connecting rod 62 has a second side 625 facing the first positioning block 70. The length of the connecting rod can be adjusted by adjusting the distance between the third fastener 65 and the fourth fastener 66 and the first side 624 of the connecting rod 62, and adjusting the distance between the fifth fastener 67 and the sixth fastener 68 and the second side 625 of the connecting rod 62.

[0129] Figure 7 This is a rear view rendering of a spliced display module provided by the present invention. Figure 8 for Figure 7 A partial enlarged view of the EE region is shown. In some examples, such as Figure 7 and Figure 8 As shown, the spliced display module 1 also includes a plurality of first connecting members 111. Any two adjacently arranged display modules 1 use the first connecting members 111 to achieve fixation and leveling in the first direction X (i.e., the left-right direction). The first direction X is the length direction of the display module 1, and is also the side-by-side direction of a row of spliced display modules 1. For any two adjacently arranged display modules 1, a first positioning hole (not shown in the figure) is provided on the back panel 10 of one of them on the splicing side S, and a second positioning hole (not shown in the figure) is provided on the back panel 10 of the other of them on the splicing side S; the first end 111a of the first connecting member 111 is detachably connected to the first positioning hole, and the second end 111b of the first connecting member 111 is detachably connected to the second positioning hole.

[0130] Optionally, the first connecting member 111 is a sheet metal structural member.

[0131] Optionally, the first end 111a of the first connector 111 can be detachably connected to the first positioning hole via a first part. The second end 111b of the first connector 111 can be detachably connected to the second positioning hole via a second part. Both the first part and the second part can be screws, and both the first positioning hole and the second positioning hole are threaded holes that mate with the screws.

[0132] Optionally, at least one of the first end 111a and the second end 111b of the first connecting member 111 has a first waist hole 1111, and the extension direction of the first waist hole 1111 is the direction from the first end 111a of the first connecting member 111 to the second end 111b (or can be understood as the first direction X), which can achieve fine adjustment of the positions of two adjacent spliced display modules 1 in the first direction X. Figure 8 As shown, the first end 111a of the first connecting member 111 has a first waist hole 1111, and the first part can pass through the first waist hole 1111 and engage with the first positioning hole to fix the first connecting member 111. The second end 111b of the first connecting member 111 has a first through hole 1112, and the second part can pass through the first through hole 1112 and engage with the second positioning hole to fix the first connecting member 111.

[0133] Figure 9 A schematic diagram of another first connector provided by the present disclosure. In some examples, such as Figure 8 or Figure 9 As shown, the first connecting member 111 includes a plurality of first connecting portions 1113 connected to each other. The plurality of first connecting portions 1113 and the back plate 10 form a closed accommodating cavity for accommodating the signal connection lines between two adjacent display modules 1 .

[0134] like Figure 8 or Figure 9 As shown, the plurality of first connection portions 1113 include four first connection portions 1113 connected end to end to form a closed loop, and a first connection portion 1113 connected to the four first connection portions 1113 on a side away from the back plate 10, forming a groove structure with an opening. Optionally, the plurality of first connection portions 1113 are connected to form an integral structure.

[0135] like Figure 8 As shown, a plurality of first connection portions 1113 are provided on a side of the back plate 10 facing away from the cover plate 30 .

[0136] like Figure 9 As shown, the first connecting member 111 is arranged on a side of the back plate 10 facing away from the cover plate 30 .

[0137] The signal connection line may be a connection line that electrically connects the driving circuit boards of two adjacent first light bars 5122 .

[0138] In some examples, such as Figure 8 or Figure 9 As shown, the first connecting member 111 further includes two first lugs 1114 , and the two first lugs 1114 are respectively connected to one end of two oppositely disposed first connecting portions 1113 close to the back plate 10 .

[0139] The two first lugs 1114 are respectively located at the first end 111a and the second end 111b of the first connector 111. Specifically, the two first lugs 1114 are respectively connected to one end of two first connecting portions 1113 arranged opposite each other along the first direction X, close to the back panel 10. Optionally, the two first lugs 1114 and the plurality of first connecting portions 1113 are connected to form an integrated structure. Here, the first lugs 1114 are parallel to the rear surface S2 of the back panel 10, which can reduce the gap between the first connector 111 and the back panel 10, making the overall appearance more regular and beautiful.

[0140] like Figure 9 As shown, the two first lugs 1114 are detachably connected to the first positioning hole and the second positioning hole respectively. Optionally, at least one of the two first lugs 1114 has a first waist hole 1111, which can achieve fine adjustment of the position of two adjacent spliced display modules 1 in the first direction X. Figure 9 As shown, one first lug 1114 has a first waist hole 1111, and a first part can pass through the first waist hole 1111 and be threadedly engaged with the first positioning hole to fix the first connecting member 111. The other first lug 1114 has a first through hole 1112, and a second part can pass through the first through hole 1112 and be threadedly engaged with the second positioning hole to fix the first connecting member 111.

[0141] In some examples, such as Figure 8 As shown, the first connecting member 111 also includes a protrusion 1115. A plurality of first connecting portions 1113 are disposed on a side of the back panel 10 away from the cover panel 30. The protrusion 1115 is connected to one of the plurality of first connecting portions 1113. The contact surface between the protrusion 1115 and the back panel 10 is different from the contact surface between the first connecting portion 1113 and the back panel 10. For example, the contact surface between the protrusion 1115 and the back panel 10 is the upper surface S1 of the upper and lower surfaces of the back panel 10 that are oppositely disposed along the second direction Y. The contact surface between the first connecting portion 1113 and the back panel 10 is the rear surface S2 of the front and rear surfaces of the back panel 10 that are oppositely disposed along its thickness direction. The second direction Y is the extension direction of the splicing side S of the display module 1. The first end of the protrusion 1115 is detachably connected to the first positioning hole; the second end of the protrusion 1115 is detachably connected to the second positioning hole.

[0142] like Figure 8 As shown, the first end 111a of the first connecting member 111 is also the first end of the protruding portion 1115, and the second end 111b of the first connecting member 111 is also the second end of the protruding portion 1115. At least one of the first end and the second end of the protruding portion 1115 has a first waist hole 1111, which can achieve fine adjustment of the position of two adjacent spliced display modules 1 in the first direction X. Figure 8 As shown, the first end of the protrusion 1115 has a first waist hole 1111, and the first part can pass through the first waist hole 1111 and engage with the first positioning hole to fix the first connecting member 111. The second end of the protrusion 1115 has a first through hole 1112, and the second part can pass through the first through hole 1112 and engage with the second positioning hole to fix the first connecting member 111.

[0143] Figure 10a for Figure 7 A partial magnified view of the FF area is shown. Figure 10b This is an enlarged view of the second connector in the FF area after disassembly. Figure 10c is an enlarged view of the second connecting member. In some examples, such as Figures 10a to 10c As shown, the spliced display module 1 further includes a plurality of second connectors 112. Any two adjacent display modules 1 are fixed in the first direction X (i.e., the left-right direction) using the second connectors 112. One second connector 112 and one first connector 111 are disposed opposite each other in the extension direction of the splicing side S (i.e., the second direction Y). For any two adjacent display modules 1, the back panel 10 of one is provided with a third positioning hole V1 on the splicing side S, and the back panel 10 of the other is provided with a fourth positioning hole V2 on the splicing side S. The first end 112a of the second connector 112 is detachably connected to the third positioning hole V1, and the second end 112b of the second connector 112 is detachably connected to the fourth positioning hole V2.

[0144] like Figure 7 As shown, the second connecting member 112 is disposed on the lower surface S3 of the upper and lower surfaces that are oppositely disposed along the second direction Y.

[0145] Optionally, the second connecting member 112 is a sheet metal structural member.

[0146] Optionally, the first end 112a of the second connector 112 can be detachably connected to the third positioning hole V1 via a third component. The second end 112b of the second connector 112 can be detachably connected to the fourth positioning hole V2 via a fourth component. Both the third component and the fourth component can be screws, and the third positioning hole V1 and the fourth positioning hole V2 are threaded holes that mate with the screws.

[0147] In some examples, such as Figures 10a to 10cAs shown, the second connecting member 112 includes a plurality of second connecting portions 1121 and two second lugs 1122 that are interconnected; the plurality of second connecting portions 1121 and the back panel 10 form a closed accommodating cavity for accommodating the signal connection lines between two adjacent display modules 1; the two second lugs 1122 are respectively connected to one end of the two oppositely arranged second connecting portions 1121 close to the back panel 10; the two second lugs 1122 are respectively detachably connected to the third positioning hole V1 and the fourth positioning hole V2.

[0148] like Figures 10a to 10c As shown, the multiple second connection parts 1121 include four second connection parts 1121 connected end to end to form a closed loop, and a second connection part 1121 connected to the side of the four second connection parts 1121 away from the back plate 10 to form a groove structure with an opening.

[0149] like Figure 10a and Figure 10c As shown, the two second lugs 1122 are respectively located at the first end 112a and the second end 112b of the second connecting member 112. Specifically, the two second lugs 1122 are respectively connected to one end of two second connecting portions 1121 arranged opposite to each other along the second direction Y and close to the back plate 10.

[0150] Optionally, the two second lugs 1122 and the plurality of second connection portions 1121 are connected into an integral structure.

[0151] like Figures 10a to 10c As shown, the two second lugs 1122 respectively have a second through hole 1123 , and the third part and the fourth part respectively pass through the second through holes 1123 on the two second lugs 1122 and respectively cooperate with the third positioning hole V1 and the fourth positioning hole V2 to achieve a detachable connection.

[0152] For example, Figure 7 As shown, the first connecting member 111 and the second connecting member 112 are respectively fixed to the upper surface S1 and the lower surface S3 of the back plate 10 which are opposite to each other along the second direction Y. The signal connection line accommodated by the first connecting member 111 is used to connect two adjacent first light strips 5122 close to the upper surface S1, that is, the following attached Figure 21c The first light bar 5122 of the second display module 1102 on the third non-joined side 102c and the first light bar 5122 of the first display module 1101 on the third non-joined side 101c. The signal connection line accommodated by the second connecting member 112 is used to connect two adjacent first light bars 5122 near the bottom surface S3, that is, the following attached Figure 21c The first light bar 5122 of the second display module 1102 on the first non-joined side 102a and the first light bar 5122 of the first display module 1101 on the first non-joined side 101a are connected.

[0153] In some examples, the signal connection line includes a first connection line and a second connection line; one end of the first connection line is electrically connected to the driver circuit board of a first light bar 5122, and the other end is a first terminal; one end of the second connection line is electrically connected to the driver circuit board of another first light bar 5122, and the other end is a second terminal; and the two first light bars are first light bars 5122 in two adjacent display modules 1. The first terminal and the second terminal are plugged together to electrically connect the driver circuit boards of the two adjacent first light bars 5122. The first terminal and the second terminal are positive and negative terminals, and they cooperate with each other to achieve self-locking and conductive connection.

[0154] Figure 11 This is a rear view rendering of another spliced display module provided by the present invention. Figure 12 for Figure 11 In some examples, such as Figure 11 As shown, the spliced display module 1 further includes a plurality of third connectors 113. For any two adjacent display modules 1, the back panel 10 of one has a first receiving portion 130 provided on the splicing side S, and the back panel 10 of the other has a second receiving portion 140 provided on the splicing side S. The third connectors 113 are detachably connected to the back panel 10 and, together with the first and second receiving portions 130, 140, form a closed cavity for accommodating signal cables between the two adjacent display modules 1.

[0155] The first receiving portion 130 and the second receiving portion 140 are spliced together to form a sink structure. Figure 11 As shown, the third connector 113 can be embedded in the recessed groove structure formed by the first accommodating portion 130 and the second accommodating portion 140, and form a closed cavity with the first accommodating portion 130 and the second accommodating portion 140. In another example, the third connector 113 protrudes from the lower surface S3 of the back plate 10, and forms a closed cavity with the first accommodating portion 130 and the second accommodating portion 140.

[0156] like Figure 12 As shown, a fifth positioning hole V3 is provided on the end of the first accommodating portion 130 away from the splicing side S, and a sixth positioning hole V4 is provided on the end of the second accommodating portion 140 away from the splicing side S; the first end of the third connecting member 113 is detachably connected to the fifth positioning hole V3; and the second end of the third connecting member 113 is detachably connected to the sixth positioning hole V4. Optionally, the first end of the third connecting member 113 can be detachably connected to the fifth positioning hole V3 via a fifth part. The second end of the third connecting member 113 can be detachably connected to the sixth positioning hole V4 via a sixth part. Both the fifth and sixth parts can be screws, and the fifth positioning hole V3 and the sixth positioning hole V4 are threaded holes that cooperate with the screws.

[0157] In some examples, the signal connection line is a flexible flat cable with third terminals at both ends. The two third terminals are respectively plugged into two adjacent display modules 1 to electrically connect the driver circuit boards of the two adjacent first light bars. The flexible flat cable is disposed within the sink structure formed by the first accommodating portion 130 and the second accommodating portion 140.

[0158] Figure 13 This is a rear view rendering of another splicing display module provided by the present disclosure. Figure 14 for Figure 13 In some examples, such as Figure 13 and Figure 14 As shown, the splicing display module 1 also includes a block structure 114 arranged corresponding to the display module 1; the block structure 114 includes a first limiting portion 1141 and a second limiting portion 1142; the first limiting portion 1141 is fixed to the non-splicing side S' of the back panel 10 and extends outward along the side away from the cover plate 30, and the second limiting portion 1142 is connected to the end of the first limiting portion 1141 away from the cover plate 30, and the plane where the second limiting portion 1142 is located forms a dihedral angle with the plane where the first limiting portion 1141 is located.

[0159] Optionally, the first stopper 1141 and the second stopper 1142 are connected as an integral structure. Optionally, the stopper structure 114 is an L-shaped sheet metal member. Optionally, the first stopper 1141 is fixed to the lower surface S3 of the upper and lower surfaces of the back panel 10 that are oppositely disposed along the second direction Y. Optionally, within an allowable manufacturing error range, the plane on which the second stopper 1142 lies is perpendicular to the plane on which the first stopper 1141 lies.

[0160] In some examples, such as Figure 14 As shown, a second waist hole 1143 is provided at one end of the first stopper 1141 away from the second stopper 1142. The second waist hole 1143 extends in the thickness direction of the display module 1 (i.e., the third direction Z). The seventh component can pass through the second waist hole 1143 to secure the stopper structure 114 to the back panel 10. The second waist hole 1143 allows for fine-tuning of the spacing between the spliced display module 1 and the fixed end in the third direction Z.

[0161] In some examples, such as Figure 14 As shown, the second limiting portion 1142 is provided with a third waist hole 1144, which extends in the direction of splicing adjacent display modules 1 (i.e., the first direction X). The eighth component can pass through the third waist hole 1144 to secure the block structure 114 to the fixed end. At this time, the plane of the second limiting portion 1142 abuts the fixed end. The fixed end includes, but is not limited to, a wall. The third waist hole 1144 can be used to fine-tune the position of the spliced display module 1 relative to the fixed end in the first direction X.

[0162] Alternatively, as Figure 13 As shown, at least two stopper structures 114 are fixed to the lower surface of the back plate 10 of a display module 1, which can improve the leveling positioning accuracy and positioning stability.

[0163] Figure 15a A schematic structural diagram of a spliced display module provided by the present disclosure. Figure 15b A schematic structural diagram of another splicing display module provided by the present disclosure. Figure 16a for Figure 15a A partial schematic diagram of the spliced display module is shown. Figure 16b for Figure 15b In some examples, such as Figure 15a 、 Figure 15b 、 Figure 16a and Figure 16b As shown, the spliced display module further includes a crossbeam 80. The crossbeam 80 is disposed on the side of the back panel 10 of each display module 1 facing away from the cover panel 30, and the back panel 10 is fixed to the crossbeam 80. The crossbeam 80 ensures that the display modules 1 are coplanar in the direction in which the crossbeam 80 extends. The crossbeam 80 can be fixedly connected to the back panel 10 via a bracket 90.

[0164] In some examples, such as Figure 15a and Figure 16a As shown, when processing a beam 80 that is too long, since the beam 80 is a strip-shaped piece, it is easy to deform during the processing. Therefore, a segmented beam 80 can be used, and each segment of the beam 80 is corresponding to a display module 1.

[0165] In some examples, in order to improve the strength of the beam 80, at least one first opening 81 is provided on the beam 80. Figure 15a and Figure 15b In the example shown, a plurality of first openings 81 are arranged side by side along the extending direction of the crossbeam 80 .

[0166] Figure 17 A schematic diagram of a partial structure of a spliced display module provided by the present disclosure. In some examples, such as Figure 17 As shown, any two adjacent display modules 1 have a first latch 90 fixed on the back panel 10 at the splicing side S of one, and a slot 100 fixed on the back panel 10 of the other at the splicing side. The first latch 90 and the slot 100 are fixedly connected. Specifically, in the spliced state, the first latch 90 is inserted into the slot 100. The first latch 90 and the slot 100 limit the position of the two adjacent display modules 1, ensuring that the cover plate 30 and display panel 20 of each display module 1 remain aligned in the horizontal and vertical directions.

[0167] Figure 18 A schematic diagram of the structure of a spliced display module provided by the present disclosure. In some examples, such as Figure 18 As shown, the display module 1 includes a control chip.

[0168] One of the display modules 1 is a first display module 101 , and the others are second display modules 102 . The control chip in the first display module 101 is a first control chip 1011 , and the control chip in the second display module 102 is a second control chip 1021 . Each second control chip 1021 is in communication with the first control chip 1011 .

[0169] The driving circuit board of the first light bar 5122 in the first display module 101 is connected to the first control chip 1; the driving circuit board of the first light bar 5122 in each second display module 102 is connected to the driving circuit board of the first light bar 5122 in the first display module 101. Specifically, the driving circuit board of the first light bar 5122 in each second display module 102 is connected to the driving circuit board of the first light bar 5122 in the first display module 101 via a signal connection line.

[0170] Figure 19 A wiring diagram of a power line provided by the present disclosure. In some examples, such as Figure 19 As shown, the first display module 101 further includes a first power line 150; the second display module 102 includes a second power line 160, each of which is electrically connected to the first power line 150, and the first power line 150 is connected to the external power module 170. The external power module 170 can be an external power socket, an external power supply, etc., and can be a module that provides voltage.

[0171] The first display module 101 is integrated with a third power interface 180 and a first power cord 150 extending from the housing. The second display module 102 is integrated with a second power cord 160 extending from the housing.

[0177] The following combination Figures 21a to 21e The splicing application scenario, wiring application scenario and communication process of the first display module 101 and the second display module 102 are described in detail.

[0178] Splicing application scenarios:

[0179] In an application scenario, such as Figure 21a As shown, the spliced display module includes a first display module 101 and two second display modules 102 . The two second display modules 102 are located on both sides of the first display module 101 . The sizes of the two second display modules 102 are the same as those of the first display module 101 .

[0180] In an application scenario, such as Figure 21b As shown, the spliced display module further includes a first display module 101 and four second display modules 102 . The four second display modules 102 are located on both sides of the first display module 101 , and the sizes of the four second display modules 102 are the same as those of the first display module 101 .

[0181] In an application scenario, such as Figure 21cAs shown, the spliced display module also includes a first display module 101 and two second display modules 102. The two second display modules 102 are located on both sides of the first display module 101. The two second display modules 102 are equal in size and smaller than the first display module 101. For example, the first display module 101 is an 86-inch display module, and the second display module 102 is a 63-inch display module.

[0182] In an application scenario, such as Figure 21d As shown, the spliced display module also includes a first display module 101 and four second display modules 102. The four second display modules 102 are spliced together in pairs along the width direction of the spliced display module. After splicing, the display modules are located on both sides of the first display module 101. The sizes of the four second display modules 102 are equal and smaller than the size of the first display module 101.

[0183] In an application scenario, such as Figure 21e As shown, the spliced display module also includes a first display module 101 and eight second display modules 102. The eight second display modules 102 are arranged around the first display module 101. The size of the second display modules 102 located on both sides of the first display module 101 along the splicing width direction is equal to the size of the first display module 101, and the size of the remaining second display modules 102 is smaller than the size of the first display module 101.

[0184] Cabling and communication application scenarios:

[0185] In the wiring application scenario, Figure 21c The illustrated spliced display module illustrates an example spliced display module of the present disclosure. Specifically, the first display module 101 has a first non-spliced side 101a, a first spliced side 101b, a second non-spliced side 101c, and a second spliced side 101d. The first non-spliced side 101a and the second non-spliced side 101c of the first display module 101 are opposite to each other, and the first spliced side 101b and the second spliced side 101d of the first display module 101 are opposite to each other.

[0186] The second display module 102 has a first non-joined side 102a, a second non-joined side 102b, a third non-joined side 102c, and a jointed side 102d. The first non-joined side 102a and the third non-joined side 102c of the second display module 102 are opposite to each other, and the second non-joined side 102b of the second display module 102 is opposite to the jointed side 102d.

[0187] The first light bars 5122 of the two second display modules 102 on the first non-joined side 102a are electrically connected to the first light bar 5122 of the first display module 101 on the first non-joined side 101a. The first light bars of the two second display modules 102 on the third non-joined side 102c are electrically connected to the first light bar 5122 of the first display module 101 on the third non-joined side 101c. The first light bar 5122 of the first display module 101 on the first non-joined side 101a is electrically connected to the first light bar 5122 of the first display module 101 on the third non-joined side 101c. The first light bar 5122 of the first display module 101 on the first non-joined side 101a or the first light bar 5122 of the first display module 101 on the third non-joined side 101c is electrically connected to the first control chip 1011. The first control chip 1011 of the first display module 101 is electrically connected to the second control chip 1021 of the second display module 102.

[0188] In the disclosed example, the first light bars 5122 of each display module form a segmented routing method, which is conducive to the assembly of the display module and avoids the problem of touch failure caused by the excessive length of the spliced display module in the splicing direction.

[0189] In some examples, because the size of the splicing display module in the splicing direction is too long, the light-emitting elements on the first light strips on both sides of the splicing display module in the splicing direction are difficult to align, resulting in touch failure. In order to solve this problem, a first fixing member is used on both sides of the splicing display module in the splicing direction instead of using a second fixing member on both sides of the splicing display module in the splicing direction, which effectively avoids the light-emitting elements on the first light strip of the third fixing component of the second fixing member on both sides of the splicing display module in the splicing direction being difficult to align, resulting in touch failure.

[0190] The first light bar 5122 can be an infrared light bar. When the spliced display module is in use, the infrared light-emitting elements on the infrared light bar on each display module emit infrared light to form a light network composed of infrared rays. When the user touches the display panel, the finger or other opaque objects will block the horizontal and vertical infrared rays passing through the touch point. The driving circuit board on the infrared light bar will parse the coordinate information of the contact point based on this, and send the information of the contact point to the control chip. The control chip generates display coordinate information based on the coordinate information of the contact point, and controls the display panel to display according to the generated display coordinate information.

[0191] In some examples, such as Figure 21cAs shown, the first display module 101 also includes a timing control module (abbreviated as T-CON) and an OPS (Open Pluggable Specification, a computing module plug-in format) computer box. The second display module 102 also includes a timing control module. The timing control module is used to receive display information sent by the control chip and control the display panel to display. The OPS computer box is used to enhance the computing power of the first control chip 1011. The OPS and the first control chip 1011 are designed to shorten the wiring as much as possible, such as a straight line connection, to reduce signal interference and radiation.

[0192] In some examples, the signal lines between the modules of the display module 1 and the power lines between the display modules 1 are separated, thereby avoiding mutual interference between the signal lines and the power lines.

[0193] Figure 22 A schematic diagram of the structure of the spliced display module provided by the present disclosure. In some examples, such as Figure 22 As shown, the first control chip 1011 includes an HDMI input port and an output port, a USB input port and an output port, and a VBO output port. The first control chip 1011 may be a SOC.

[0194] Typically, PCs, set-top boxes, and laptops transmit video signals to the display SoC. These signals are transmitted between external devices and use formats such as VGA, DVI, and HDMI. The SoC can convert video signals into formats supported by the TCON, such as VGA to LVDS and HDMI to VBO. The SoC can also control functions such as power on and off, backlight brightness, and audio playback.

[0195] Specifically, such as Figure 21c and Figure 22As shown, the first light bar 5122 of the first display module 101 on the first non-splicing side 101a or the first light bar 5122 of the first display module 101 on the third non-splicing side 101c can send the touch coordinate signal to the first control chip 1011 through the USB data cable. The first control chip 1011 can also receive an input signal from the HDMI input port, and the source of the input signal can be an external computer. The first control chip 1011 can send the display coordinate information to the second control chip 1021 through the HDMI output port. The first control chip 1011 can also send the display coordinate information to the timing control module through the VBO output port. The first control chip 1011 can also send the touch coordinate information to the OPS computer box through the USB output port, and receive the display coordinate information returned by the OPS computer box based on the touch coordinate signal through the HDMI input port. Among them, HDMI input and output can support multiple resolutions, for example, 2400*2160, 3840*2160 and other resolutions, VBO output can support multiple resolutions, for example, 2400*2160, 3840*2160 and other resolutions.

[0196] The spliced display module of the disclosed example supports touch signal input, realizing touch and display coordinate mapping; supports OPS computer box control and display; supports touch coordinate output and HDMI input. Through the spliced display module of the disclosed example, it is possible to realize the interaction of multiple display screens of multiple display modules, support multiple screens to display a complete screen in one, support each display screen to independently display different content, support three screens to independently display different applications, support the display screen of the second display module to synchronously display the same screen, support the display screens of multiple second display modules to exchange with each other, support multiple people to write on multiple display modules at the same time, support the saving of written content, and support wireless screen projection.

[0197] The following is Figure 21c In the following example, the first light bar 5122 on the first non-splicing side 101a of the first display module 101 is electrically connected to the first control chip 1011, and the first light bar 5122 is an infrared light bar.

[0198] Scenario 1: The infrared light bar located on the first non-joined side 101a of the first display module 101 controls the display area of the first display module 101, and the infrared light bar located on the second non-joined side 101c of the first display module 101 controls the display area of the first display module 101, and the contact is located in the display area 2 of the first display module 101.

[0199] The driving circuit board of the infrared light bar of the first display module 101 located on the second non-splicing side 101c obtains a touch signal, parses the touch coordinate information based on the touch signal, and sends the touch coordinate information to the driving circuit board of the infrared light bar of the first display module 101 located on the first non-splicing side 101a. The coordinate information is then sent to the first control chip 1011 via the driving circuit board of the infrared light bar on the first non-splicing side 101a. The first control chip 1011 generates corresponding display coordinate information based on the coordinate information, and controls the display panel 20 for display based on the display coordinate information.

[0200] Scenario 2: The infrared light bar of the second display module 102 located on the first non-joined side 102a controls the display area of the second display module 102, and the infrared light bar of the second display module 102 located on the third non-joined side 102c controls the display area of the second display module 102, and the contact is located in the display area 1 of the second display module 102.

[0201] The driving circuit board of the infrared light bar of the second display module 102 located on the first non-splicing side 102a obtains the touch signal, parses the touch coordinate information based on the touch signal, and sends the touch coordinate information to the driving circuit board of the infrared light bar of the first display module 101 located on the first non-splicing side 101a. The coordinate information is sent to the first control chip 1011 through the driving circuit board of the infrared light bar on the first non-splicing side 101a. The first control chip 1011 generates corresponding display coordinate information based on the coordinate information and sends the display coordinate information to the second control chip 1021 of the second display module 102. After receiving the display coordinate information, the second control chip 1021 controls its corresponding display panel 20 for display.
