[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; and "inside" and "outside" refer to the outline of the device.
[0034] In existing splicing devices, a light bar is usually set between two display devices to eliminate the splicing seam between the spliced display devices, but the existing fill light structure is difficult to maintain and install. This application proposes the following technical solutions to solve the above technical problems.
[0035] Referring to Figures 1 to 16, the present application proposes a spliced display device 100, including at least two display devices 200, a fill light component 300 and an adapter bracket 400. A seam 500 is provided 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 a portion of the adapter bracket 400 extends into the seam 500. The fill light component 300 and the adapter bracket 400 can be positioned separately, and the adapter bracket 400 is connected to at least one of the two adjacent display devices 200.
[0036] In this embodiment, the display device 200 may be an LCD display device, a Mini LED display device, a Micro LED display device, or other light-emitting display devices.
[0037] Please refer to Figure 3. The fill light assembly 300 may include a light bar 10 located on the light-emitting side 201 of two adjacent display devices 200, and the two sides of the light bar 10 are respectively overlapped with the two display devices 200 and cover at least a portion of the seam 500. At the same time, a plurality of driver chips 120 may be provided on the side of the light bar 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 bar 10 facing the light-emitting side 201. The driver chip 120 is used to control the plurality of light-emitting elements. The adapter bracket 400 and the detachable positioning portion of the fill light assembly 300 are located within the orthographic projection of the plane where the seam 500 is located.
[0038] The present application sets an adapter bracket 400 on the backlight side 202 of one of two adjacent display devices 200, and detachably positions the fill light component 300 provided with the driver chip 120 from the adapter bracket 400, so that the light bar 10 in the fill light component and the adapter bracket 400 can be detachably positioned, thereby simplifying the installation and disassembly of the light bar 10 and facilitating the front maintenance of the light bar 10 with integrated lamp and driver.
[0039] It should be noted that the fill light assembly 300 may further include an 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, with a first end of the first transmission member 30 electrically connected to the side of the light bar facing away from the light-emitting side, and a second end of the first transmission member 30 facing the backlight side 202 and passing 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, and the second transmission member 50 is located on the backlight side 202 of two adjacent display devices 200, and the first end of the second transmission member 50 is detachably connected to the adapter plate 20.
[0040] It should be noted that the number of display devices 200 can be 2n. For example, in the 1X2 combination splicing display device 100 in Figure 1, there is one seam 500 between two adjacent display devices 200, and the fill light component 300 is used to eliminate the seam 500 between two adjacent display devices 200; or, in the 2X2 splicing display device 100 composed of four display devices 200, there are four seams 500 between the four display devices 200, and it is necessary to set one fill light component 300 in each of the four seams 500. In the following embodiments, the technical solution of the present application is illustrated using the 1X2 combination splicing display device 100 in Figures 1 and 2.
[0041] It should be noted that, as shown in Figures 1 and 2, the present application can set 7 light strips 10 between two adjacent display devices 200, and each light strip 10 is provided with a first connector 310, and at the same time, one light strip 10 corresponds to one adapter plate 20, and one adapter plate 20 is connected to one second transmission member 50, and four second transmission members 50 are connected to the same controller 60. For example, in the structure of Figure 3, four second transmission members 50 are connected to the same controller 60, and the other three second transmission members 50 are connected to another controller 60; and 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.
[0042] It should be noted that the light-emitting elements on the light strip 10 can be set as conventional LEDs, Mini LEDs or Micro LEDs, and the LEDs of corresponding sizes can be set according to the size and resolution of the spliced display device 100. The light-emitting elements can be LED devices that emit red, green and blue light.
[0043] 3 , the fill light assembly 300 further 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 .
[0044] It should be noted that in order to improve the structural strength of the adapter bracket 400, the number of adapter brackets 400 between two adjacent display devices 200 can be one, and one adapter bracket 400 can carry multiple light strips 10, and the adapter brackets 400 do not need to be spliced.
[0045] It should be noted that the adapter bracket 400 of the present application can be detachably connected to the display device 200.
[0046] It should be noted that, in this application, the length direction of the light bar 10 is the X direction, the width direction of the light bar 10 is the Y direction, and the thickness direction of the light bar 10 is the Z direction.
[0047] The technical solution of this application is now described in conjunction with specific embodiments.
[0048] In the spliced display device 100 of the present application, referring to Figures 4 to 6 and Figures 9 to 11, the fill light assembly 300 further includes at least two connectors 110 disposed on the side of the light bar 10 facing away from the light-emitting side 201. The at least two connectors 110 are arranged in the length direction of the light bar 10. The connectors 110 and the adapter bracket 400 can be positioned separately, and at least two connectors 110 are located within the splicing seam 500.
[0049] In this embodiment, the adapter bracket 400 may include a top plate 410 , and the at least two connectors 110 and the top plate 410 may be detachably positioned.
[0050] Referring to Figures 4, 5, and 11, the connector 110 may be a magnetic metal pad, primarily used to magnetically attach the light bar 10 to the adapter bracket 400. To facilitate the detachability of the light bar 10, a magnetic member 411 may be provided on the adapter bracket 400 in this embodiment to magnetically attach the light bar 10 to the adapter bracket 400. This simplifies the installation of the light bar 10, and the detachable positioning of the light bar 10 and the adapter bracket 400 facilitates disassembly of the light bar 10 for front maintenance.
[0051] It should be noted that the detachable positioning of the present application may include a detachable connection and a detachable setting of the connector 110 and the magnetic component 411, and the detachable connection of the connector 110 and the magnetic component 411 may include a magnetic connection and a snap-fit between the connector 110 and the magnetic component 411.
[0052] Please refer to Figure 14. The connector 110 and the magnetic component 411 can be set 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 making the connector 110 and the magnetic component 411 detachable.
[0053] Please refer to Figure 13. There can be a gap between the connector 110 and the magnetic component 411, that is, the connector 110 and the magnetic component 411 can be separately arranged. 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 are not in contact, the light strip 10 can be fastened to the module structure in the joint 500.
[0054] In this embodiment, the gap may be 0.05 mm to 0.2 mm.
[0055] In this embodiment, in order to ensure seamless fitting of the light bar 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 bar 10 and the surface of the display device 200 are fitted together, the connector 110 can be embedded in the seam 500 .
[0056] In this embodiment, in order to minimize the seam 500 of the light bar 10 , the width of the seam 500 of the present application needs to be smaller than the width of the light bar 10 , so as to achieve seamless splicing of the display device 200 .
[0057] At the same time, the spacing between the light-emitting elements on the light bar 10 and the light-emitting elements in the adjacent display device 200 needs to be close to or equal to the spacing between two adjacent light-emitting elements in the display device 200, so as to achieve equal spacing between two adjacent light-emitting elements at any position on the spliced display device 100; if multiple columns of light-emitting elements are provided on the light bar 10, the spacing between two adjacent light-emitting elements on the light bar 10 needs to be close to or equal to the spacing between two adjacent light-emitting elements in the display device 200, so as to achieve equal spacing between two adjacent light-emitting elements at any position on the spliced display device 100, thereby meeting the uniformity of the distribution of light-emitting elements.
[0058] In this embodiment, three connecting parts 110 can be set on one light strip 10, and the intervals between two adjacent connecting parts 110 can be equal or unequal. The intervals between two adjacent connecting parts 110 in this application are unequal; the connecting parts 110 can be fixedly connected to the back of the light strip 10 through an adhesive layer, such as 416 instant adhesive, or fixedly connected to the back of the light strip 10 through welding materials such as soldering.
[0059] 4 to 6 and 9 to 11 , a plurality of driver chips 120 may be disposed between two adjacent connectors 110 , a first connector 310 may be disposed between two adjacent connectors 110 , and a first transmission member 30 and the plurality of driver chips 120 may be arranged sequentially in the length direction of the light bar 10 .
[0060] In this embodiment, the driver chip 120 is directly integrated into the light bar 10, achieving a design that integrates both light and driver. This eliminates the need for an additional driver chip 120 on the backlight side 202 of the spliced display device 100, simplifying the structure of the fill light assembly 300. Furthermore, each driver chip 120 can control a row or column of light-emitting elements. When there are a sufficient number of driver chips 120, one driver chip 120 can control only one light-emitting element.
[0061] In the structures of Figures 4 to 6 and Figures 9 to 11, 15 driver chips 120 are provided on a light strip 10, the 1st to 8th driver chips 120 are arranged between the 1st connector 110 and the first transmission member 30, and the 9th to 15th driver chips 120 are arranged between the 2nd connector 110 and the 3rd connector 110, that is, the 3 connectors 110, the 15 driver chips 120 and the 1st transmission member 30 can be arranged in sequence in the length direction of the light strip 10.
[0062] In this embodiment, other devices such as capacitors are further provided on both sides of the second connecting member 110 .
[0063] 4 to 6 and 9 to 11 , the adapter bracket 400 may further include a bottom plate 420 and a support plate 430 connecting the top plate 410 and the bottom plate 420 , wherein the bottom plate 420 and the top plate 410 are arranged parallel to the light bar 10 , and the support plate 430 is arranged perpendicular to the bottom plate 420 and the top plate 410 .
[0064] In this embodiment, the top plate 410 protrudes from the support plate 430 along a first direction, and the bottom plate 420 protrudes from the support plate 430 along a second direction. The first direction and the second direction are both parallel to the width direction Y of the light bar 10, and the first direction and the second direction are opposite, that is, the adapter bracket 400 composed of the bottom plate 420, the support plate 430 and the top plate 410 is Z-shaped.
[0065] 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 connecting member 110, and the connecting member 110 and the magnetic component 411 are magnetically attracted to each other.
[0066] In the structures of Figures 4, 5 and 11, the number of magnetic components 411 is the same as the number of connectors 110. For example, three connectors 110 are provided on the light bar 10, and three magnetic components 411 corresponding to the three connectors 110 are provided on the top plate 410. The magnetic attraction between the connectors 110 and the magnetic components 411 can make the light bar 10 and the adapter bracket 400 detachable and connected.
[0067] The present application sets an adapter bracket 400 on the backlight side 202 of two adjacent display devices 200, and the light bar 10 and the adapter bracket 400 are magnetically connected through the connector 110 and the magnetic component 411 to achieve a detachable connection, which also simplifies the installation of the light bar 10 and facilitates the overall maintenance of the fill light assembly 300.
[0068] In this embodiment, a screw may be provided at the 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 to be screwed to the screw. The inner wall of the fixing hole 413 is provided with a thread, and the screw and the fixing hole 413 cooperate to fix the magnetic component 411 on the top plate 410.
[0069] In this embodiment, a groove corresponding to the connector 110 may be provided on the end face of the magnetic component 411 close to the light-emitting side 201, and the connector 110 may be embedded in the groove; when the connector 110 and the magnetic component 411 are magnetically attracted to each other, in order to prevent the light strip 10 from shaking on the plane where the length direction X and the width direction Y of the light strip 10 are located on the adapter bracket 400, the setting of the groove limits the shaking of the connector 110 on the plane.
[0070] 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 . One connector 110 corresponds to one buckle 414 , and the connector 110 and the buckle 414 are engaged with each other.
[0071] In this embodiment, the connector 110 can be a buckle, and the connection between the connector 110 and the buckle 414 enables the light bar 10 to be detachably connected to the top plate 410 of the adapter bracket 400. The following describes the technical solution of this application with the connector 110 as a magnetic gasket.
[0072] Referring to Figure 7 , the first transmission member can be a printed circuit board (not shown). One end of the first transmission member can be directly connected to the binding device 130 of the light bar 10, and the other end of the first transmission member is connected to the adapter board. The first transmission member 30 is typically processed by chemical etching of FCCL (flexible copper clad foil) to produce a flexible circuit board with a single-sided, double-sided, or multi-layer structure with different circuit patterns. Furthermore, the first end of the first transmission member 30 is detachably connected to the side of the light bar 10 facing away from the light output side 201, and the second end of the first transmission member 30 is detachably connected to the adapter board 20.
[0073] Please refer to Figures 4 to 6 and Figures 8 to 11. The first transmission member 30 may include a first connector 310 and a second connector 320 that are detachably connected. The first connector 310 may be arranged on the light strip 10 facing away from the light emitting side 201. The first connector 310 extends toward the backlight side 202 and passes through the seam 500. The second connector 320 may be arranged on the adapter plate 20 facing the light emitting side 201.
[0074] It should be noted that, referring to Figures 4 to 6 and Figures 8 to 11, the first connector 310 of the present application is integrated on the light bar 10, and the second connector 320 is integrated on the adapter plate 20. The detachable connection between the first connector 310 and the second connector 320 makes the light bar 10 and the adapter plate 20 detachably connected. At the same time, the adapter plate 20 and the second transmission member 50 are detachable, as well as the detachable connection between the fill light assembly 300 and the adapter bracket 400, so that all components of the present application are detachable, which facilitates the front maintenance and installation of each component.
[0075] It should be noted that at least one third connector 70 is further 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 the third connector 70 on the adapter plate 20 .
[0076] It should be noted that the second transmission member 50 may be a flexible flat cable. The second transmission member 50 is usually made of two layers of insulating foil, upper and lower layers, with a flat copper foil sandwiched in between.
[0077] It should be noted that, referring to Figure 12, the first connector 310, the light strip 10 and the adapter plate 20 are arranged vertically, and the first connector 310 and the second connector 320 are separated from the two adjacent display devices 200, that is, the first connector 310 and the second connector 320 can both be arranged in 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 the two adjacent second transmission members 50 can be partially overlapped.
[0078] It should be noted that the positions of sections AA and BB in FIG1 are merely schematic diagrams. The structure in FIG12 is a schematic diagram of a section in this direction passing through the first connector 310 and the second connector 320. FIG13 and FIG14 are schematic diagrams of a section in this direction passing through the connector 110 and the magnetic member 411. Furthermore, FIG12 to FIG14 are not final structural diagrams and are merely schematic diagrams for the purpose of facilitating the description of the structure.
[0079] Please refer to 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 socket of the signal connector, and the second connector 320 can be a male socket of the signal. The first connector 310 and the second connector 320 can be snap-connected.
[0080] When the light bar is fixedly connected to the adapter bracket, the first connector 310 and the second connector 320 cannot be accurately connected due to alignment tolerance. In the structure shown in Figure 10, the first connector 310 and the second connector 320 are movable in the width direction Y and the length direction X of the light bar 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 be moved on the second connector 320 in the width direction Y and the length direction X of the light bar 10, thereby resolving the technical problem of the first connector 310 and the second connector 320 not being accurately connected.
[0081] 10 , the first connector 310 and the second connector 320 are retractably connected in the thickness direction Z of the light bar 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 first connector 310 and the second connector 320 can be connected to each other, thereby reserving an alignment tolerance in the thickness direction Z of the light bar 10.
[0082] In this embodiment, the first connector 310 moves up and down as a whole in the thickness direction Z of the light bar 10; alternatively, the first connector 310 may include a first sub-component 311 fixedly connected to the light bar 10 and a second sub-component 312 connected to the first sub-component 311, the second sub-component 312 and the second connector 320 being snap-fitted, the second sub-component 312 being telescopically connected to the first sub-component 311 along the thickness direction Z of the light bar 10, that is, the second sub-component 312 slides along the thickness direction Z of the light bar 10, and a tolerance is reserved in the thickness direction Z of the light bar 10 to solve the technical problem that the first connector 310 and the second connector 320 cannot be accurately snap-fitted.
[0083] In this embodiment, the movable distance of the first connector 310 in the thickness direction Z of the light bar 10 may be 1 mm to 5 mm.
[0084] Referring to FIG. 11 , the first transmission member 30 may be a probe connector. The first connector 310 may further include a base 313 and a plurality of connection pins 314 disposed on the base 313. The second connector 320 includes a plurality of connection ports (not shown), with one connection pin 314 embedded within each connection port. The number of connection ports may be greater than or equal to the number of connection pins 314. Similarly, similar to FIG. 10 , in this embodiment, the first connector 310 and the second connector 320 are movable and connectable in the length direction X, width direction Y, and thickness direction Z of the light bar 10.
[0085] In the following embodiments, description is given by taking an example where the first transmission member 30 includes a first connector 310 and a second connector 320 .
[0086] Since a plurality of magnetic components 411 corresponding to the plurality of connectors 110 are provided on the top plate 410, and the connectors 110, the first connector 310 and the plurality of driver chips 120 are arranged in sequence in the length direction of the light strip 10, the orthographic projections of the connector 110, the first connector 310 and the plurality of driver 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 setting of the top plate 410 will interfere with the first connector 310.
[0087] 5 , 6 and 11 , at least one cutout 412 is defined on the top plate 410 , and the first transmission member 30 passes through the cutout 412 to connect with the corresponding adapter plate 20 .
[0088] In this embodiment, the number of break points 412 can be the same as the number of first connectors 310, and the size of the break points 412 in the length direction of the light bar 10 can be larger than the size of the first connector 310 in the length direction of the light bar 10; the setting of the break points 412 allows the first connector 310 to pass through the break points 412 and extend toward a side away from the light bar 10, or the second connector 320 can pass through the break points 412 and extend toward one side of the light bar 10.
[0089] Please refer to Figures 4 to 6, 9 and 11. A fixing column 440 is provided on the side of the top plate 410 facing away from the light-emitting side 201. The fixing column 440 is provided on both sides of the fracture 412. The fixing column 440 extends from the top plate 410 to the bottom plate 420. The adapter plate 20 is detachably connected to the fixing column 440.
[0090] In the structures of Figures 4 to 6 and Figures 10 and 11, a third connector 70 is provided on the adapter plate 20, and the third connector 70 is electrically connected to the second connector 320; at the same time, two first through holes HL1 are also provided on the adapter plate 20, and the two first through holes HL1 can be located on both sides of the third connector 70. The first through holes HL1 correspond to the fixing columns 440, and the fixing columns 440 are provided with threaded holes. Fasteners can pass through the first through holes HL1 and be screwed to the threaded holes in the fixing columns 440 to fix the adapter plate 20 on the adapter bracket 400.
[0091] 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 column 440 facing away from the light-emitting side 201 and the light bar 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 light bar 10, that is, the fixing column 440 needs to protrude from the surface of the base plate 420 facing away from the light-emitting side 201.
[0092] In this embodiment, a plurality of third through holes HL3 are further provided on the base plate 420, and a threaded hole corresponding to the third through hole HL3 is provided on the backlight side 202 of one of the two display devices 200. The fastener can pass through the third through hole HL3 and be screwed to the threaded hole in the display device 200 to fix the adapter bracket 400 on the display device 200; for example, the spliced 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, and the base plate 420 can be fixedly connected to the first display device 210, as shown in the structure of Figure 15.
[0093] In this embodiment, since threaded holes need to be set on the top plate 410, and in order to ensure the fixing force between the magnetic component 411 and the top plate 410, the threaded holes need to have a certain depth, and only through holes need to be set on the bottom plate 420 to allow the fasteners to 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.
[0094] Please refer to Figures 8, 9 and 11. Two third connectors 70 can be provided on the adapter plate 20, and the second transmission member 50 can select one of them according to the position of the controller 60; at the same time, two first through holes HL1 are provided between the two third connectors 70, and fasteners can pass through the first through holes HL1 and be screwed to the threaded holes in the fixing column 440 to fix the adapter plate 20 on the fixing column 440.
[0095] Please refer to Figures 8, 9 and 11. The third connector 70 close to the first display device 210 is provided with two second through holes HL2 on both sides of the length direction of the light bar 10. The third connector 70 close to the second display device 220 is provided with two fourth through holes HL4 on both sides of the length direction of the light bar 10. The second through holes HL2 correspond to the third through holes HL3 on the bottom plate 420. The fasteners can pass through the second through holes HL2 and the third through holes HL3 and be screwed to 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, the fasteners can pass through the fourth through holes HL4 and be screwed to the threaded holes in the second display device 220 to fix the adapter plate 20 on the two second display devices 220.
[0096] In addition, the third through hole HL3 can be replaced by a threaded hole, that is, the fastener can pass through the second through hole HL2 and be screwed to the threaded hole on the bottom plate 420 to fix the adapter plate 20 on the bottom plate 420.
[0097] Please refer to Figure 16. Each display device 200 may include a backlight module 211, a display panel 212 arranged on the backlight module 211, and a packaging cover 214 arranged on the display panel 212. The light bar 10 and part of the adapter bracket 400 may be located in the joint 500; wherein, the surface of the light bar 10 facing the light emitting side 201 and the surface of the packaging cover 214 facing the light emitting side 201 are located on the same plane.
[0098] In this embodiment, the light strip 10 can be overlapped on the display panel 212, and the thickness of the light strip 10 can be the same as the thickness of the packaging cover 214, so that the surfaces of the light strip 10 and the packaging cover 214 facing the light-emitting side 201 are located on the same plane, ensuring the flatness of the light-emitting surface of the spliced display device 200.
[0099] Please refer to Figure 16. Since there is an optical film layer on the display panel 212, in order to prevent the movement of the light bar 10 from damaging the optical film layer on the display panel 212, the present application can make the area of the adhesive layer 213 located between the display panel 212 and the packaging cover plate 214 larger than the area of the packaging cover plate 214, that is, the light bar 10 can be overlapped on the adhesive layer 213 that exceeds the boundary of the packaging cover plate 214. The adhesive layer 213 is a flexible material, which can prevent the light bar from damaging the optical film layer on the display panel 212.
[0100] In this embodiment, the material of the adhesive layer 213 may be optical adhesive.
[0101] Since the light bar 10 is directly overlapped on the adhesive layer 213, the light bar 10 will adhere to the adhesive layer 213, and the adhesive layer 213 has strong viscosity. When the light bar 10 is disassembled or undergoes pre-maintenance treatment, the light bar 10 and the adhesive layer 213 are difficult to separate. 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.
[0102] In this embodiment, the spliced display device 100 further includes a release member 80 , which is disposed on a side of the adhesive layer 213 away from the display panel 212 and in an area corresponding to the adhesive layer 213 and the light bar 10 .
[0103] In this embodiment, the light bar 10 at least partially overlaps with the display panels 212 of two adjacent display devices 200, and a release member 80 may be disposed between the light bar 10 and the corresponding display panels 212. The release member 80 isolates the adhesive layer 213 from the light bar 10, eliminating adhesion between the light bar 10 and the adhesive layer 213. This allows for easy separation of the light bar 10 and the adhesive layer 213 during disassembly or pre-maintenance of the light bar 10, preventing the formation of adhesive residue.
[0104] In this embodiment, the material of the anti-sticking member 80 can be plastic such as polyethylene terephthalate (PET), polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), polylactic acid (PLA), polycarbonate (PC), and acrylic (PMMA).
[0105] It should be noted that the anti-sticking member 80 shown on the light bar 10 in Figures 8 and 9 only indicates that the anti-sticking member 80 can be located on the side of the light bar 10 away from the light emitting direction, and the anti-sticking member 80 is not bonded to the surface of the light bar 10 away from the light emitting direction.
[0106] Please refer to FIG. 16 . A buffer member 90 may be further provided between the display panel 212 and the light bar 10 . The buffer member 90 is located in the seam 500 and away from the anti-adhesive member 80 . The buffer member 90 may be used to support the light bar 10 .
[0107] In this embodiment, the distance from the upper surface of the package cover plate 214 to the upper surface of the display panel 212 can be equal to the sum of the thickness of the light bar 10 and the thickness of the buffer member 90. Since the buffer member 90 is disposed between the light bar 10 and the display panel 212, and the package cover plate 214 is disposed on the display panel 212, in order to make the upper surface of the package cover plate 214 flush with the upper surface of the light bar 10, the distance from the upper surface of the package cover plate 214 to the upper surface of the display panel 212 needs to be equal to the sum of the thickness of the light bar 10 and the thickness of the buffer member 90.
[0108] It should be noted that the distance from the surface of the packaging cover 214 facing away from the display panel 212 to the display panel 212 is equal to the sum of the thickness of the light bar 10 and the thickness of the buffer 90, which not only includes the situation where they are completely equal, but also includes the situation where they are basically equal within the allowable error range; for example, the distance from the surface of the packaging 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 light bar 10 and the thickness of the buffer 90, or the distance from the surface of the packaging 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 light bar 10 and the thickness of the buffer 90.
[0109] In this embodiment, the material of the buffer member 90 may be silicone or foam adhesive. Silicone or foam adhesive has a certain degree of elasticity. When located between the display panel 212 and the light bar 10, it forms a buffer, reducing damage to the display panel 212 during installation and removal, and improving the stability of the connection between the light bar 10 and the display panel 212. Furthermore, the silicone or foam adhesive can change thickness when subjected to external forces, making it easier to adjust the flatness of the packaging cover plate 214 and the light bar 10, ensuring that the upper surface of the light bar 10 is flush with the upper surface of the packaging cover plate 214.
[0110] Please refer to Figure 16. The sum of the thickness of the adhesive layer 213 and the thickness of the packaging cover plate 214 can be equal to the sum of the thickness of the buffer member 90 and the thickness of the light bar 10. When the adhesive layer 213 is arranged between the packaging cover plate 214 and the display panel 212, in order to make the upper surface of the packaging cover plate 214 flush with the upper surface of the light bar 10, the sum of the thickness of the adhesive layer 213 and the thickness of the packaging cover plate 214 must be equal to the sum of the thickness of the buffer member 90 and the thickness of the light bar 10.
[0111] In this embodiment, equal not only includes the case where the front and rear values are completely equal, but also includes the case where the front and rear 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 packaging cover plate 214 is slightly larger than the sum of the thickness of the buffer 90 and the thickness of the light bar 10, or the sum of the thickness of the adhesive layer 213 and the thickness of the packaging cover plate 214 is slightly smaller than the sum of the thickness of the buffer 90 and the thickness of the light bar 10.
[0112] At the same time, the thickness of the buffer 90 can be greater than or equal to the sum of the thickness of the release member 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 release member 80 and the thickness of the adhesive layer 213, the light bar 10 is in contact with both the buffer 90 and the release member 80; when the thickness of the buffer 90 is equal to the sum of the thickness of the release member 80 and the thickness of the adhesive layer 213, the light bar 10 is in contact with the buffer 90, but there is a gap between the light bar 10 and the release member 80. Therefore, the present application can adjust the flatness of the light bar 10 and the packaging cover plate 214 on the light output side 201 by adjusting the thickness of the buffer 90.
[0113] In this embodiment, the thickness of the anti-sticking member 80 needs to be less than a preset value, that is, the sum of the thickness of the anti-sticking member 80 and the thickness of the adhesive layer 213 is less than or equal to the thickness of the buffer member 90, so as to prevent the thickness of the anti-sticking member 80 from being too large to lift up the light bar 10 after assembling the display device 200, resulting in the upper surface of the light bar 10 being not flush with the upper surface of the packaging cover plate 214.
[0114] In this embodiment, when the thickness of the anti-sticking member 80 is less than a preset value, the height of the upper surface of the light bar 10 can be adjusted only by adjusting the thickness of the buffer member 90, so that the upper surface of the light bar 10 is flush with the upper surface of the packaging cover 214.
[0115] In the structure of Figure 16, the orthographic projection of the anti-sticking member 80 on the display panel 212 and the orthographic projection of the buffer member 90 on the display panel 212 can both be located within the range of the orthographic projection of the light bar 10 on the display panel 212, that is, the anti-sticking member 80 and the buffer member 90 can both be located within the joint 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 member 80 and the buffer member 90 of the display panel 212 are located, thereby improving the display effect of the display panel 212.
[0116] In this embodiment, the thickness range of the packaging cover plate 214 can be 1.5mm to 2.2mm, the thickness range of the light strip 10 can be 1.0mm to 1.5mm, the thickness range of the buffer member 90 can be 0.3mm to 1.7mm, the thickness range of the anti-sticking member 80 can be 0.1mm to 1.4mm, and the thickness range of the adhesive layer 213 can be 0.3mm to 0.5mm; for example, the thickness of the adhesive layer 213 is one of 0.30mm, 0.32mm, 0.34mm, 0.36mm, 0.38mm, 0.40mm, 0.42mm, 0.44mm, 0.46mm, 0.48mm, and 0.50mm.
