[0067] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0068] In existing splicing devices, a light strip is typically placed between two display devices to eliminate the seams between them. However, the maintenance and installation of existing supplementary lighting structures are quite difficult. This application proposes the following technical solutions to address the aforementioned technical problems.

[0069] Please see Figures 1 to 16 This application proposes a splicing display device 100, including at least two display devices 200, a fill light assembly 300 and an adapter bracket 400. There is a splicing seam 500 between two adjacent display devices 200. The adapter bracket 400 can be located on the backlight side 202 of the two adjacent display devices 200, and part of the adapter bracket 400 extends into the splicing seam 500. The fill light assembly 300 and the adapter bracket 400 can be separated and positioned. The adapter bracket 400 is connected to at least one of the two adjacent display devices 200.

[0070] In this embodiment, the display device 200 can be an LCD display device, a Mini LED display device, a Micro LED display device, or other light-emitting display devices.

[0071] Please see Figure 3 The supplementary lighting assembly 300 may include a light strip 10 located on the light-emitting side 201 of two adjacent display devices 200, with the two sides of the light strip 10 respectively overlapping the two display devices 200 and covering at least a portion of the seam 500; at the same time, a plurality of driving chips 120 may be provided on the side of the light strip 10 facing away from the light-emitting side 201, and a plurality of light-emitting elements may be provided on the side of the light strip 10 facing the light-emitting side 201. The driving chips 120 are used to control the plurality of light-emitting elements. The detachable positioning part of the adapter bracket 400 and the supplementary lighting assembly 300 is located within the orthographic projection of the plane where the seam 500 is located.

[0072] This application provides an adapter bracket 400 on the backlight side 202 of one of two adjacent display devices 200, and the supplementary light assembly 300 with driver chip 120 is separably positioned from the adapter bracket 400, so that the lamp strip 10 in the supplementary light assembly can be separably positioned from the adapter bracket 400, which simplifies the installation and disassembly of the lamp strip 10 and facilitates the front maintenance of the lamp strip 10 with integrated lamp and driver.

[0073] It should be noted that the supplementary lighting assembly 300 may also include a connecting adapter plate 20, a first transmission member 30, and a second transmission member 50. The first transmission member 30 is located within the seam 500, and its first end is electrically connected to the side of the lamp strip facing away from the light-emitting side. The second end of the first transmission member 30 is connected to the side facing the backlight side 202 and passes through the seam 500. The adapter plate 20 is fixed to the side of the adapter bracket 400 away from the light-emitting side 201. The second transmission member 50 is located on the backlight side 202 of two adjacent display devices 200, and its first end and the adapter plate 20 are detachably connected.

[0074] It should be noted that the number of display devices 200 can be 2n, for example Figure 1 In a 1x2 splicing display device 100, there is one seam 500 between two adjacent display devices 200. A supplementary lighting component 300 is used to eliminate the seam 500 between the two adjacent display devices 200. Alternatively, in a 2x2 splicing display device 100 consisting of four display devices 200, there are four seams 500 between the four display devices 200. Therefore, a supplementary lighting component 300 needs to be installed in each of the four seams 500. In the following embodiments, [the following is an example]. Figure 1 and Figure 2 The 1x2 splicing display device 100 in this application describes the technical solution of this application.

[0075] It should be noted that, as Figure 1 and Figure 2 As shown, this application can provide seven light strips 10 between two adjacent display devices 200, and each light strip 10 is provided with a first connector 310. Each light strip 10 corresponds to one adapter board 20, and each adapter board 20 is connected to one second transmission component 50. Four second transmission components 50 are connected to the same controller 60, for example... Figure 3 In the structure, four second transmission components 50 are connected to the same controller 60, and another three second transmission components 50 are connected to another controller 60; when the length of the seam 500 is small, fewer light strips 10 can be set, and the number of light strips 10 is mainly determined by the length of the seam 500 and the length of the light strip 10 itself.

[0076] It should be noted that the light-emitting elements on the light strip 10 can be conventional LEDs, Mini LEDs or Micro LEDs. The LEDs of corresponding sizes can be set according to the size and resolution of the splicing display device 100. The light-emitting elements can be LED devices that emit red, green and blue light.

[0077] It should be noted that you should refer to [link / reference]. Figure 3 The supplementary lighting assembly 300 also includes a controller 60, which can be a HUB. The controller 60 can be fixed to the backlight side 202 of one of the two adjacent display devices 200, and the second end of the second transmission member 50 is electrically connected to the controller 60.

[0078] It should be noted that, in order to improve the structural strength of the adapter bracket 400, there can be only one adapter bracket 400 between two adjacent display devices 200. One adapter bracket 400 can support multiple light strips 10, and the adapter bracket 400 does not need to be spliced.

[0079] It should be noted that the adapter bracket 400 of this application can be detachably connected to the display device 200.

[0080] It should be noted that in this application, the length direction of the light strip 10 is taken as the X direction, the width direction of the light strip 10 is taken as the Y direction, and the thickness direction of the light strip 10 is taken as the Z direction.

[0081] The technical solution of this application will now be described in conjunction with specific embodiments.

[0082] In the splicing display device 100 of this application, please refer to Figures 4 to 6 and Figures 9 to 11 The supplementary lighting assembly 300 also includes at least two connectors 110 disposed on the side of the light strip 10 facing away from the light-emitting side 201. The at least two connectors 110 are arranged in the length direction of the light strip 10. The connectors 110 are separable from the adapter bracket 400 and the at least two connectors 110 are located within the seam 500.

[0083] In this embodiment, the adapter bracket 400 may include a top plate 410, and at least two connectors 110 and the top plate 410 are separable and positionable.

[0084] Please see Figure 4 , Figure 5 and Figure 11The connector 110 can be a magnetic metal pad, mainly used to magnetically attract the light strip 10 to the adapter bracket 400. In order to facilitate the detachment of the light strip 10, a magnetic component 411 can be provided in the adapter bracket 400 to magnetically attract the light strip 10 to the adapter bracket 400. While simplifying the installation of the light strip 10, the separable positioning of the light strip 10 and the adapter bracket 400 can facilitate the disassembly of the light strip 10 for front maintenance.

[0085] It should be noted that the separable positioning of this application may include the detachable connection and separable arrangement of the connector 110 and the magnetic component 411. The detachable connection of the connector 110 and the magnetic component 411 may include the magnetic connection and snap-fit ​​between the connector 110 and the magnetic component 411.

[0086] Please see Figure 14 The connector 110 and the magnetic component 411 can be in contact. Due to the magnetic attraction between the connector 110 and the magnetic component 411, the light strip 10 can be fastened in the module structure within the seam 500, thereby enabling the connector 110 and the magnetic component 411 to be detachably connected.

[0087] Please see Figure 13 There may be a gap between the connector 110 and the magnetic component 411, that is, the connector 110 and the magnetic component 411 can be set separately. Since there is a magnetic attraction between the connector 110 and the magnetic component 411, when the attraction and repulsion between the connector 110 and the magnetic component 411 are equal, even if the connector 110 and the magnetic component 411 do not contact each other, the light strip 10 can be fastened to the module structure within the seam 500.

[0088] In this embodiment, the gap can be from 0.05mm to 0.2mm.

[0089] In this embodiment, in order to ensure seamless bonding between the light strip 10 and the surface of the display device 200, the position of the connector 110 corresponds to the seam 500. That is, when the light strip 10 is bonded to the surface of the display device 200, the connector 110 can be embedded into the seam 500.

[0090] In this embodiment, in order for the light strip 10 to eliminate the seam 500 as much as possible, the width of the seam 500 in this application needs to be smaller than the width of the light strip 10, so as to achieve seamless splicing of the display device 200.

[0091] Meanwhile, the distance between the light-emitting elements on the light strip 10 and the light-emitting elements in the adjacent display device 200 needs to be close to or equal to the distance between two adjacent light-emitting elements in the display device 200, so as to achieve equal distance between two adjacent light-emitting elements at any position on the splicing display device 100; if multiple rows of light-emitting elements are provided on the light strip 10, the distance between two adjacent light-emitting elements on the light strip 10 needs to be close to or equal to the distance between two adjacent light-emitting elements in the display device 200, so as to achieve equal distance between two adjacent light-emitting elements at any position on the splicing display device 100, and to satisfy the uniformity of the distribution of light-emitting elements.

[0092] In this embodiment, three connectors 110 can be provided on one light strip 10. The interval between two adjacent connectors 110 can be equal or unequal. In this application, the interval between two adjacent connectors 110 is unequal. The connectors 110 can be fixedly connected to the back of the light strip 10 by an adhesive layer, such as 416 instant adhesive, or by a soldering material such as soldering.

[0093] Please see Figures 4 to 6 and Figures 9 to 11 Multiple driver chips 120 can be disposed between two adjacent connectors 110, and a first connector 310 can be disposed between two adjacent connectors 110. The first transmission component 30 and multiple driver chips 120 are arranged sequentially along the length of the light strip 10.

[0094] In this embodiment, the driver chip 120 is directly integrated into the light strip 10, realizing a unified light and driver design. This eliminates the need for an additional driver chip 120 on the backlight side 202 of the splicing display device 100, simplifying the structure of the supplementary lighting component 300. Furthermore, each driver chip 120 can control one row or one column of light-emitting elements. When the number of driver chips 120 is sufficient, one driver chip 120 can control only one light-emitting element.

[0095] exist Figures 4 to 6 and Figures 9 to 11 In the structure, a light strip 10 is provided with 15 driving chips 120. The first to eighth driving chips 120 are disposed between the first connector 110 and the first transmission member 30, and the ninth to fifteenth driving chips 120 are disposed between the second connector 110 and the third connector 110. That is, the three connectors 110, the 15 driving chips 120 and the first transmission member 30 can all be arranged sequentially along the length of the light strip 10.

[0096] In this embodiment, capacitors and other devices are also provided on both sides of the second connector 110.

[0097] Please see Figures 4 to 6 and Figures 9 to 11The adapter bracket 400 may also include a base plate 420 and a support plate 430 connecting the top plate 410 and the base plate 420. The base plate 420 and the top plate 410 are arranged parallel to the light strip 10, and the support plate 430 is arranged perpendicular to the base plate 420 and the top plate 410.

[0098] In this embodiment, the top plate 410 protrudes from the support plate 430 along the first direction, and the bottom plate 420 protrudes from the support plate 430 along the second direction. Both the first and second directions are parallel to the width direction Y of the light strip 10, and the directions of the first and second directions are opposite. That is, the adapter bracket 400 formed by the bottom plate 420, the support plate 430 and the top plate 410 is Z-shaped.

[0099] In this embodiment, the light strip 10 is detachably connected to the top plate 410. For example, at least two magnetic components 411 are provided on the side of the top plate 410 facing the light-emitting side 201, and the magnetic components 411 are fixed on the top plate 410. At the same time, a magnetic component 411 corresponds to a connector 110, and the connector 110 and the magnetic component 411 are magnetically attracted to each other.

[0100] exist Figure 4 , Figure 5 and Figure 11 In the structure, the number of magnetic components 411 is the same as the number of connectors 110. For example, the light strip 10 is provided with 3 connectors 110, and the top plate 410 is provided with 3 magnetic components 411 corresponding to the 3 connectors 110. The magnetic attraction between the connectors 110 and the magnetic components 411 allows the light strip 10 and the adapter bracket 400 to be detachably connected.

[0101] This application provides an adapter bracket 400 on the backlight side 202 of two adjacent display devices 200. At the same time, the light strip 10 and the adapter bracket 400 are magnetically connected through the connector 110 and the magnetic component 411 to achieve a detachable connection. This also simplifies the installation of the light strip 10 and facilitates the overall maintenance of the supplementary lighting assembly 300.

[0102] In this embodiment, a screw may be provided at one end of the magnetic component 411 facing away from the light-emitting side 201, and a fixing hole 413 may be provided on the top plate 410 for screwing with the screw. The inner wall of the fixing hole 413 is threaded, and the cooperation between the screw and the fixing hole 413 fixes the magnetic component 411 on the top plate 410.

[0103] In this embodiment, the end face of the magnetic component 411 near the light-emitting side 201 may be provided with a groove corresponding to the connector 110, and the connector 110 may be embedded in the groove. When the connector 110 and the magnetic component 411 are magnetically attracted, in order to prevent the light strip 10 from wobbling on the plane containing the length direction X and width direction Y of the light strip 10 on the adapter bracket 400, the groove restricts the wobbling of the connector 110 on this plane.

[0104] Please see Figure 6 At least two buckles 414 are provided on the side of the top plate 410 facing the light-emitting side 201. The buckles 414 are located on the top plate 410. A connector 110 corresponds to a buckle 414, and the connector 110 and the buckle 414 are engaged.

[0105] In this embodiment, the connector 110 can be a snap fastener. The snap-fit ​​between the connector 110 and the snap fastener 414 allows the light strip 10 to be detachably connected to the top plate 410 of the adapter bracket 400. The technical solution of this application will now be described with the connector 110 as a magnetic pad.

[0106] Please see Figure 7 The first transmission component can be a printed circuit board (not shown). One end of the first transmission component can be directly connected to the bonding device 130 of the light strip 10, and the other end of the first transmission component is connected to the adapter board. The first transmission component 30 is usually processed by chemical etching to obtain a flexible circuit board with different single-sided, double-sided or multi-layer structures of FCCL (flexible copper clad foil) with different circuit patterns. At the same time, the first end of the first transmission component 30 is detachably connected to the side of the light strip 10 facing away from the light-emitting side 201, and the second end of the first transmission component 30 is detachably connected to the adapter board 20.

[0107] Please see Figures 4 to 6 and Figures 8 to 11 The first transmission component 30 may include a detachably connected first connector 310 and second connector 320. The first connector 310 may be disposed on the back of the light-emitting side 201 of the light strip 10. The first connector 310 extends toward the backlight side 202 and passes through the seam 500. The second connector 320 may be disposed on the adapter plate 20 facing the light-emitting side 201.

[0108] It should be noted that you should refer to [link / reference]. Figures 4 to 6 and Figures 8 to 11 The first connector 310 of this application is integrated on the light strip 10, and the second connector 320 is integrated on the adapter plate 20. The detachable connection of the first connector 310 and the second connector 320 makes the light strip 10 and the adapter plate 20 detachable. At the same time, the adapter plate 20 is detachable from the second transmission component 50, and the supplementary lighting component 300 and the adapter bracket 400 are detachable, so that all components of this application can be disassembled, which facilitates front maintenance and installation of each component.

[0109] It should be noted that at least one third connector 70 is also provided on the side of the adapter plate 20 facing away from the light-emitting side 201, and the first end of the second transmission member 50 can be electrically connected to one of the third connectors 70 on the adapter plate 20.

[0110] It should be noted that the second transmission component 50 can be a flexible flat cable. The second transmission component 50 typically utilizes two layers of insulating foil and a flat copper foil sandwiched in between.

[0111] It should be noted that you should refer to [link / reference]. Figure 12 The first connector 310, the light strip 10, and the adapter plate 20 are arranged vertically. The first connector 310 and the second connector 320 are both separated from the two adjacent display devices 200, that is, the first connector 310 and the second connector 320 can both be located within the seam 500. In this embodiment, since the distance between the controller 60 and the adapter plate 20 is small, the longer second transmission member 50 can be bent, and two adjacent second transmission members 50 can be partially overlapped.

[0112] It should be noted that, Figure 1 The positions of the mid-section AA and section BB are for illustrative purposes only. Figure 12 The structure shown is a schematic diagram of a cross-section passing through the first connector 310 and the second connector 320 in this direction. Figure 13 and Figure 14 This is a schematic diagram showing the cross-section passing through the connector 110 and the magnetic member 411 in this direction. Additionally, Figures 12 to 14 This is not the final structural diagram; it is only a schematic diagram for the purpose of describing the structure.

[0113] Please see Figures 4 to 6 and Figures 8 to 10 The first connector 310 and the second connector 320 can be signal connectors, such as KEL connectors; the first connector 310 can be a female connector for the signal connector, and the second connector 320 can be a male connector for the signal connector; the first connector 310 and the second connector 320 can be snapped together.

[0114] When the light strip is fixedly connected to the adapter bracket, due to alignment tolerances, the first connector 310 and the second connector 320 cannot be accurately engaged. Figure 10 In the structure shown, the first connector 310 and the second connector 320 are movably connected in the width direction Y and the length direction X of the light strip 10. In this embodiment, the area of ​​the second connector 320 is larger than the area of ​​the first connector 310, that is, the first connector 310 can move on the second connector 320 in the width direction Y and the length direction X of the light strip 10, so as to solve the technical problem that the first connector 310 and the second connector 320 cannot be accurately engaged.

[0115] At the same time, Figure 10In the structure shown, the first connector 310 and the second connector 320 are telescopically connected in the thickness direction Z of the light strip 10. For example, the first connector 310 and the second connector 320 do not need to be fully engaged; as long as the first connector 310 and the second connector 320 are partially engaged, the connectors of the first connector 310 and the second connector 320 can be realized, so as to reserve a positioning tolerance in the thickness direction Z of the light strip 10.

[0116] In this embodiment, the first connector 310 moves vertically as a whole in the thickness direction Z of the light strip 10; or, the first connector 310 may include a first sub-device 311 fixedly connected to the light strip 10 and a second sub-device 312 connected to the first sub-device 311. The second sub-device 312 and the second connector 320 are engaged. The second sub-device 312 can be telescopically connected to the first sub-device 311 in the thickness direction Z of the light strip 10, that is, the second sub-device 312 slides in the thickness direction Z of the light strip 10. A tolerance is reserved in the thickness direction Z of the light strip 10 to solve the technical problem that the first connector 310 and the second connector 320 cannot be accurately engaged.

[0117] In this embodiment, the distance between the movable first connector 310 in the thickness direction Z of the light strip 10 can be 1mm to 5mm.

[0118] Please see Figure 11 The first transmission component 30 can be a probe connector. The first connector 310 can also include a base 313 and a plurality of connecting pins 314 disposed on the base 313. The second connector 320 includes a plurality of connection ports (not shown), a connecting pin 314 is embedded in a connection port, and the number of connection ports can be greater than or equal to the number of connecting pins 314. Meanwhile, with... Figure 10 Similarly, in this embodiment, the first connector 310 and the second connector 320 can be movably connected in the length direction X, width direction Y and thickness direction Z of the light strip 10.

[0119] In the following embodiments, the first transmission component 30 includes a first connector 310 and a second connector 320 as an example for illustration.

[0120] Since the top plate 410 is provided with multiple magnetic components 411 corresponding to multiple connectors 110, and the connectors 110, the first connector 310 and multiple driving chips 120 are arranged sequentially along the length of the light strip 10, the orthogonal projections of the connectors 110, the first connector 310 and the multiple driving chips 120 on the top plate 410 may all be located within the top plate 410; and the first connector 310 needs to be connected to the second connector 320 located on one side of the bottom plate 420, the arrangement of the top plate 410 will interfere with the first connector 310.

[0121] Please see Figure 5 , Figure 6 and Figure 11 At least one break 412 is provided on the top plate 410, and the first transmission member 30 passes through the break 412 to connect with the corresponding adapter plate 20.

[0122] In this embodiment, the number of breaks 412 can be the same as the number of first connectors 310, and the dimension of the breaks 412 in the length direction of the light strip 10 can be greater than the dimension of the first connectors 310 in the length direction of the light strip 10. The breaks 412 are provided so that the first connectors 310 can pass through the breaks 412 and extend away from the light strip 10, or the second connectors 320 can pass through the breaks 412 and extend toward the side of the light strip 10.

[0123] Please see Figures 4 to 6 , Figure 9 and Figure 11 A fixing post 440 is provided on the side of the top plate 410 facing away from the light-emitting side 201. The fixing post 440 is located on both sides of the cut 412. The fixing post 440 extends along the direction from the top plate 410 to the bottom plate 420. The adapter plate 20 is detachably connected to the fixing post 440.

[0124] exist Figures 4 to 6 and Figure 10 and Figure 11 In the structure, the adapter plate 20 is provided with a third connector 70, which is electrically connected to the second connector 320; at the same time, the adapter plate 20 is also provided with two first through holes HL1, which can be located on both sides of the third connector 70. The first through holes HL1 correspond to the fixing post 440. The fixing post 440 is provided with a threaded hole. Fasteners can pass through the first through holes HL1 and be screwed into the threaded hole in the fixing post 440 to fix the adapter plate 20 on the adapter bracket 400.

[0125] In this embodiment, in order to avoid interference between the adapter plate 20 and the base plate 420, the distance between the surface of the fixing post 440 facing away from the light-emitting side 201 and the lamp strip 10 needs to be greater than the distance between the surface of the base plate 420 facing away from the light-emitting side 201 and the lamp strip 10, that is, the fixing post 440 needs to protrude from the surface of the base plate 420 facing away from the light-emitting side 201.

[0126] In this embodiment, the base plate 420 is also provided with a plurality of third through holes HL3. The backlight side 202 of one of the two display devices 200 is provided with threaded holes corresponding to the third through holes HL3. Fasteners can pass through the third through holes HL3 and be screwed into the threaded holes in the display device 200 to fix the adapter bracket 400 to the display device 200. For example, the splicing display device 100 includes a first display device 210 and a second display device 220. The first display device 210 partially overlaps with the base plate 420. The controller 60 is fixed on the second display device 220. The base plate 420 can be fixedly connected to the first display device 210, such as... Figure 15 The structure shown.

[0127] In this embodiment, since the top plate 410 needs to be provided with threaded holes, and in order to ensure the fixing force of the magnetic component 411 and the top plate 410, the threaded holes need to have a certain depth, while the bottom plate 420 only needs to be provided with through holes so that the fastener can pass through the through holes and be fixedly connected to one of the two display devices 200, the thickness of the top plate 410 needs to be greater than the thickness of the bottom plate 420.

[0128] Please see Figure 8 , Figure 9 and Figure 11 The adapter plate 20 may be provided with two third connectors 70, and the second transmission component 50 may select one of them according to the location of the controller 60. At the same time, two first through holes HL1 are provided between the two third connectors 70. Fasteners can pass through the first through holes HL1 and be screwed into the threaded holes in the fixing post 440 to fix the adapter plate 20 on the fixing post 440.

[0129] Please see Figure 8 , Figure 9 and Figure 11 The third connector 70 near the first display device 210 has two second through holes HL2 on both sides of the length direction of the light strip 10, and the third connector 70 near the second display device 220 has two fourth through holes HL4 on both sides of the length direction of the light strip 10. The second through holes HL2 correspond to the third through holes HL3 on the base plate 420. Fasteners can pass through the second through holes HL2 and the third through holes HL3 and be screwed into the threaded holes in the first display device 210 to fix the adapter plate 20 and the adapter bracket 400 on the first display device 210. At the same time, fasteners can pass through the fourth through holes HL4 and be screwed into the threaded holes in the second display device 220 to fix the adapter plate 20 on the two second display devices 220.

[0130] Alternatively, the third through hole HL3 can be replaced with a threaded hole, that is, the fastener can pass through the second through hole HL2 and be screwed into the threaded hole on the base plate 420 to fix the adapter plate 20 on the base plate 420.

[0131] Please see Figure 16 Each display device 200 may include a backlight module 211, a display panel 212 disposed on the backlight module 211, and an encapsulation cover plate 214 disposed on the display panel 212. The lamp strip 10 and part of the adapter bracket 400 may be located within the seam 500. The surface of the lamp strip 10 facing the light-emitting side 201 and the surface of the encapsulation cover plate 214 facing the light-emitting side 201 are located on the same plane.

[0132] In this embodiment, the light strip 10 can overlap the display panel 212, and the thickness of the light strip 10 can be the same as the thickness of the encapsulation cover plate 214, so that the surfaces of the light strip 10 and the encapsulation cover plate 214 facing the light-emitting side 201 are on the same plane, ensuring the flatness of the light-emitting surface of the spliced ​​display device 200.

[0133] Please see Figure 16 Since there is an optical film layer on the display panel 212, in order to prevent the movement of the light strip 10 from damaging the optical film layer on the display panel 212, this application can make the area of ​​the adhesive layer 213 located between the display panel 212 and the encapsulation cover plate 214 larger than the area of ​​the encapsulation cover plate 214. That is, the light strip 10 can overlap on the adhesive layer 213 that extends beyond the boundary of the encapsulation cover plate 214. The adhesive layer 213 is a flexible material, which can prevent the light strip from damaging the optical film layer on the display panel 212.

[0134] In this embodiment, the adhesive layer 213 can be made of optical adhesive.

[0135] Since the LED strip 10 is directly attached to the adhesive layer 213, the LED strip 10 will be bonded to the adhesive layer 213. However, the adhesive layer 213 has strong adhesion, making it difficult to separate the LED strip 10 and the adhesive layer 213 when disassembling or performing pre-maintenance. At the same time, the residual adhesive layer 213 will cause dark lines to appear on the edge of the display device 200, affecting the display effect of the display device 200.

[0136] In this embodiment, the splicing display device 100 further includes an anti-adhesion component 80, which is disposed on the side of the adhesive layer 213 away from the display panel 212, and is disposed in the area of ​​the adhesive layer 213 corresponding to the light strip 10.

[0137] In this embodiment, the light strip 10 at least partially overlaps with the display panels 212 in two adjacent display devices 200, and the anti-adhesive component 80 can be disposed between the light strip 10 and the corresponding display panel 212. The anti-adhesive component 80 can isolate the adhesive layer 213 from the light strip 10, so that there is no adhesive force between the light strip 10 and the adhesive layer 213. When the light strip 10 is disassembled or pre-maintenance is performed, the light strip 10 and the adhesive layer 213 can be easily separated, and the presence of residual adhesive is avoided.

[0138] In this embodiment, the material of the anti-stick component 80 can be plastics such as polyethylene terephthalate (PET), polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), polylactic acid (PLA), polycarbonate fiber (PC), and acrylic (PMMA).

[0139] It should be noted that, Figure 8 and Figure 9 The anti-stick element 80 shown on the light strip 10 only indicates that the anti-stick element 80 can be located on the side of the light strip 10 away from the light emission direction, but the anti-stick element 80 is not bonded to the surface of the light strip 10 on the side away from the light emission direction.

[0140] Please see Figure 16 A buffer 90 can also be provided between the display panel 212 and the light strip 10. The buffer 90 is located within the seam 500 and is set away from the anti-sticking part 80. The buffer 90 can be used to support the light strip 10.

[0141] In this embodiment, the distance from the upper surface of the encapsulation cover 214 to the upper surface of the display panel 212 can be equal to the sum of the thickness of the LED strip 10 and the thickness of the buffer member 90. Since the buffer member 90 is disposed between the LED strip 10 and the display panel 212, and the encapsulation cover 214 is disposed on the display panel 212, in order to make the upper surface of the encapsulation cover 214 flush with the upper surface of the LED strip 10, the distance from the upper surface of the encapsulation cover 214 to the upper surface of the display panel 212 must be equal to the sum of the thickness of the LED strip 10 and the thickness of the buffer member 90.

[0142] It should be noted that the distance from the surface of the encapsulation cover 214 facing away from the display panel 212 to the display panel 212 is equal to the sum of the thickness of the lamp strip 10 and the thickness of the buffer member 90. This includes not only the case where they are completely equal, but also the case where they are basically equal within the allowable error range. For example, the distance from the surface of the encapsulation cover 214 facing away from the display panel 212 to the display panel 212 may be slightly greater than the sum of the thickness of the lamp strip 10 and the thickness of the buffer member 90, or the distance from the surface of the encapsulation cover 214 facing away from the display panel 212 to the display panel 212 may be slightly less than the sum of the thickness of the lamp strip 10 and the thickness of the buffer member 90.

[0143] In this embodiment, the buffer 90 can be made of silicone or foam adhesive. Silicone or foam adhesive has a certain degree of elasticity. When it is located between the display panel 212 and the LED strip 10, it forms a buffer, reducing damage to the display panel 212 during installation and disassembly, and improving the stability of the connection between the LED strip 10 and the display panel 212. Simultaneously, the thickness of the silicone or foam adhesive can change under external force, thus facilitating the adjustment of the flatness between the encapsulation cover 214 and the LED strip 10, ensuring that the upper surface of the LED strip 10 is flush with the upper surface of the encapsulation cover 214.

[0144] Please see Figure 16 The sum of the thickness of the adhesive layer 213 and the thickness of the encapsulation cover 214 can be equal to the sum of the thickness of the buffer 90 and the thickness of the light strip 10. When the adhesive layer 213 is disposed between the encapsulation cover 214 and the display panel 212, in order to make the upper surface of the encapsulation cover 214 flush with the upper surface of the light strip 10, the sum of the thickness of the adhesive layer 213 and the thickness of the encapsulation cover 214 must be equal to the sum of the thickness of the buffer 90 and the thickness of the light strip 10.

[0145] In this embodiment, "equal to" includes not only the case where the two values ​​are completely equal, but also the case where the two values ​​are basically equal within the allowable error range; for example, the sum of the thickness of the adhesive layer 213 and the thickness of the encapsulation cover plate 214 is slightly greater than the sum of the thickness of the buffer 90 and the thickness of the light strip 10, or the sum of the thickness of the adhesive layer 213 and the thickness of the encapsulation cover plate 214 is slightly less than the sum of the thickness of the buffer 90 and the thickness of the light strip 10.

[0146] Meanwhile, the thickness of the buffer 90 can be greater than or equal to the sum of the thickness of the anti-sticking component 80 and the thickness of the adhesive layer 213. When the thickness of the buffer 90 is equal to the sum of the thickness of the anti-sticking component 80 and the thickness of the adhesive layer 213, the light strip 10, the buffer 90, and the anti-sticking component 80 are all in contact; when the thickness of the buffer 90 is equal to the sum of the thickness of the anti-sticking component 80 and the thickness of the adhesive layer 213, the light strip 10 and the buffer 90 are in contact, but there is a gap between the light strip 10 and the anti-sticking component 80. Therefore, this application can adjust the flatness of the light strip 10 and the encapsulation cover 214 on the light-emitting side 201 by adjusting the thickness of the buffer 90.

[0147] In this embodiment, the thickness of the anti-adhesive component 80 needs to be less than a preset value, that is, the sum of the thickness of the anti-adhesive component 80 and the thickness of the adhesive layer 213 is less than or equal to the thickness of the buffer component 90, so as to prevent the anti-adhesive component 80 from being too thick and lifting the light strip 10 after the display device 200 is assembled, resulting in the upper surface of the light strip 10 not being flush with the upper surface of the encapsulation cover plate 214.

[0148] In this embodiment, when the thickness of the anti-sticking component 80 is less than a preset value, the height of the upper surface of the light strip 10 can be adjusted by simply adjusting the thickness of the buffer component 90, so that the upper surface of the light strip 10 is flush with the upper surface of the encapsulation cover plate 214.

[0149] exist Figure 16In the structure, the orthographic projection of the anti-sticking component 80 on the display panel 212 and the orthographic projection of the buffer component 90 on the display panel 212 can both be located within the range of the orthographic projection of the light strip 10 on the display panel 212. That is, the anti-sticking component 80 and the buffer component 90 can both be located within the seam 500. When the user views the display device 200 from the front, dark lines or dark spots are avoided in the area where the anti-sticking component 80 and the buffer component 90 of the display panel 212 are located, thereby improving the display effect of the display panel 212.

[0150] In this embodiment, the thickness of the encapsulation cover 214 can range from 1.5mm to 2.2mm, the thickness of the light strip 10 can range from 1.0mm to 1.5mm, the thickness of the buffer 90 can range from 0.3mm to 1.7mm, the thickness of the anti-sticking component 80 can range from 0.1mm to 1.4mm, and the thickness of the adhesive layer 213 can range from 0.3mm to 0.5mm; for example, the thickness of the adhesive layer 213 can be one of the following values: 0.30mm, 0.32mm, 0.34mm, 0.36mm, 0.38mm, 0.40mm, 0.42mm, 0.44mm, 0.46mm, 0.48mm, and 0.50mm.

[0151] It should be noted that, in this application, the upper surface of the display panel 212 is the surface of the display panel 212 near the light-emitting side 201, the upper surface of the lamp strip 10 is the surface of the lamp strip 10 near the light-emitting side 201, and the upper surface of the encapsulation cover 214 is the surface of the encapsulation cover 214 near the light-emitting side 201.

[0152] Please see Figures 3 to 14 This application also proposes a light-emitting module 600, which includes an adapter bracket 400 and a supplementary light component 300. The supplementary light component 300 and the adapter bracket 400 can be separated and positioned. The supplementary light component 300 may include a light strip 10, an adapter plate 20, a first connector 310 and a second connector 320.

[0153] In this embodiment, the adapter plate 20 is fixed to the side of the adapter bracket 400 away from the light-emitting surface 101 of the lamp strip 10, the first connector 310 is located on the side of the lamp strip 10 away from the light-emitting surface 101, and the second connector 320 is located on the side of the adapter plate 20 facing the light-emitting surface 101 of the lamp strip 10. The first connector 310 and the second connector 320 are detachably connected.

[0154] In this embodiment, the side of the light strip 10 facing the light-emitting surface 101 is provided with a plurality of light-emitting elements, and the side of the light strip 10 facing away from the light-emitting surface 101 is provided with a plurality of driving chips 120, which are used to control the plurality of light-emitting elements.

[0155] It should be noted that the first connector 310 and the second connector 320 constitute the first transmission component 30, which can be replaced with... Figure 7 and Figure 11 The structure in.

[0156] The light strip in this application is provided with a driver chip 120, and the light strip 10 and the adapter bracket 400 can be separated and positioned separately, so that the light strip 10 in the supplementary lighting assembly can be separated and positioned separately, which simplifies the installation and disassembly of the light strip 10 and facilitates the front maintenance of the light strip 10 that integrates the light and driver.

[0157] In this embodiment, the supplementary lighting component 300 further includes a second transmission component 50 and a controller 60. The first end of the second transmission component 50 is detachably connected to the adapter plate 20, and the second end of the second transmission component 50 is electrically connected to the controller 60.

[0158] In the light-emitting module of this application, at least two connectors 110 are provided on the side of the light strip 10 facing away from the light-emitting surface 101, and the at least two connectors 110 are separable from the adapter bracket 400 for positioning. For example Figure 4 and Figure 5 The middle connector 110 can be a magnetic pad. Figure 6 The middle connector 110 can be a snap-fit.

[0159] This application provides a splicing display device and a light-emitting module; the display device includes at least two display devices, a supplementary light component, and an adapter bracket. The adapter bracket is located on the backlight side of two adjacent display devices, and a portion of the adapter bracket extends into the splicing seam.
