DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only 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 ordinary technical workers in the field without making creative work are within the scope of protection of this application.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] In the related art, the light strip made of a glass substrate is connected and lit by welding CNT (connector) or a circuit board to an external power source, so that the light strip and the connector form an integrated structure. When a light strip is damaged, the entire light board must be replaced, which makes the product maintenance cost high and is inconvenient to replace and maintain a single light strip.

[0022] In order to solve the above problems, the present application provides a light board and a display device.

[0023] See also Figures 1 to 9 , Figure 1 It is a schematic diagram of the structure provided by this application; Figure 1 : is a schematic diagram of the three-dimensional structure of a light board provided in an embodiment of the present application; wherein the positive electrode and the negative electrode of the conductive layer are respectively arranged at two ends of the glass substrate; Figure 2 yes Figure 1 The structural diagram of the light bar provided; Figure 3 yes Figure 1 A schematic diagram of the structure of part A in the middle; Figure 4 yes Figure 1 A schematic diagram of the structure of part B in the middle; Figure 5 : is a schematic diagram of a three-dimensional structure of a lamp panel provided in another embodiment of the present application; wherein the positive electrode and the negative electrode of the conductive layer are arranged at the same end of the glass substrate; Figure 6 yes Figure 5 The structural diagram of the light bar provided; Figure 7 yes Figure 5 A schematic diagram of the structure enlargement of the C part; Figure 8 : is a schematic diagram of a three-dimensional structure of a light panel provided in another embodiment of the present application; wherein the positive electrode and the negative electrode of the conductive layer are arranged at the same end of the glass substrate, and each glass substrate is provided with two rows of light-emitting units; Fig. 9 yes Figure 8 A schematic diagram of the structure of the light bar provided.

[0024] like Figures 1 to 9As shown, the light board 100 provided by the present application includes a plurality of splicing units 10, each splicing unit 10 includes a light bar 1 and a connecting component 2, the light bar 1 includes a glass substrate 11, a conductive layer 12 disposed on the surface of the glass substrate 11, and a plurality of light-emitting units 13; wherein the conductive layer 12 is electrically connected to the light-emitting unit 13; the light-emitting unit 13 can be an LED, a mini LED or a micro LED, etc., and the present application does not limit this. It can be understood that the light board 100 spliced ​​by a plurality of splicing units 10 can be used for a direct-down backlight module or an edge-entry backlight module.

[0025] The conductive layer 12 can be electrically connected to the flexible printed circuit (FPC) 50 through the connecting component 2. The conductive layer 12 includes a positive electrode 121 and a negative electrode 122, and the positive electrode 121 and the negative electrode 122 can be arranged at the same end or opposite ends of the glass substrate 11.

[0026] In one embodiment, if Figures 1 to 4 As shown, the positive electrode 121 and the negative electrode 122 are respectively arranged at the two ends of the glass substrate 11, and the flexible circuit board 50 is arranged at both ends of the glass substrate 11. The positive electrode 121 of the conductive layer 12 is connected to the positive electrode 121 of the conductive layer 12 through the positive electrode (not marked in the figure) of one flexible circuit board 50, and the negative electrode (not marked in the figure) of the other flexible circuit board 50 is connected to the negative electrode 122 of the conductive layer 12 to form a driving circuit.

[0027] In another embodiment, if Figures 5 to 9 As shown in the figure, the positive electrode 121 and the negative electrode 122 are arranged at the same end of the glass substrate 11, and the flexible circuit board 50 can be arranged at only one end of the glass substrate 11, and the positive electrode 121 of the conductive layer 12 is connected through the positive electrode of the flexible circuit board 50, and the negative electrode 122 of the conductive layer 12 is connected through the negative electrode of the flexible circuit board 50 to form a driving circuit. When the positive electrode 121 and the negative electrode 122 of the conductive layer 12 are arranged at the same end of the glass substrate 11, the number of flexible circuit boards 50 arranged can be reduced, and the manufacturing cost of the light board 100 can be reduced.

[0028] The connecting component 2 is disposed at the end of the glass substrate 11 and is detachably connected to the light bar 1; the detachable connection between the connecting component 2 and the light bar 1 allows the damaged light bar 1 or the connecting component 2 to be repaired or replaced at any time, and facilitates the installation of the connecting component 2 and the light bar 1. The connecting component 2 can fix the glass substrate 11 on the one hand, and can conduct the conductive layer 12 with the external circuit (such as the flexible circuit board 50) on the other hand, forming a driving circuit of the light-emitting unit 13.

[0029] In one embodiment, each splicing unit 10 may include one, two or more light bars 1. Figures 8 to 9 As shown, when a single connecting component 2 is used to clamp two or more rows of light strips 1, compared with the case where a single connecting component 2 only clamps one row of light strips 1, the number of connecting components 2 can be greatly reduced, thereby reducing costs; at the same time, the installation time of the connecting component 2 can be reduced, thereby improving assembly efficiency.

[0030] Among them, the connection components 2 at the same end of the multiple splicing units 10 are detachably connected. When multiple light strips 1 are spliced, a connection component 2 is set at the end of each light strip 1, and the multiple connection components 2 located at the same end of each light strip 1 are detachably connected to each other. The detachable connection between the multiple connection components 2 is different from the integrated or welded connection components 2 in the prior art. The detachable connection between the multiple connection components 2 allows each light strip 1 to be relatively independent. If the light strip 1 of one of the multiple splicing units 10 fails or is damaged, the splicing unit 10 can be disassembled, and the corresponding light strip 1 or the corresponding connection component 2 of the splicing unit 10 can be repaired or replaced, so that a single light strip 1 can be replaced without replacing the entire light panel 100, saving product production costs and maintenance costs. When installing the present application, a single connecting component 2 is first installed on the end of the light strip 1, and then multiple connecting components 2 are assembled to form an integral light panel 100. Compared with the integral direct-down glass substrate 11, the manufacturing process is greatly simplified, which helps to improve the manufacturing yield of the light strip 1 and thus reduce costs.

[0031] See also Figures 10 to 14 , Fig.10 is a schematic diagram of the side structure of a light board provided in one embodiment of the present application; Fig.11 yes Fig.10 A schematic diagram of the structure of the D part; Fig.12 is a structural schematic diagram of a supporting connector provided in one embodiment of the present application; Fig.13 yes Fig.12 The enlarged schematic diagram of the structure of part E in the middle; Fig.14 yes Fig.12 Schematic diagram of the enlarged structure of part F.

[0032] like Figures 1 to 4 , Figures 10 to 14As shown, in one embodiment, the light panel 100 may further include a support connector 30, which is detachably connected to the connection assembly 2 at the same end of the plurality of splicing units 10. For example, each splicing unit 10 includes two ends, namely a first end 101 and a second end 102, the first ends 101 of the plurality of splicing units 10 are the same end, and the second ends 102 of the plurality of splicing units 10 are also the same end; the support connector 30 may be detachably connected to the first ends 101 of the plurality of splicing units 10, and may also be detachably connected to the second ends 102 of the plurality of splicing units 10. The support connector 30 may be detachably connected to the connection assembly 2 at the same end of the plurality of splicing units 10 by means of snap connection, magnetic attraction, and connection with a latch 203. The supporting connector 30 can support the same end of multiple splicing units 10, which can prevent bending, rotation, displacement, etc. between the multiple detachably connected connection components 2, so that the multiple detachably connected connection components 2 can remain relatively fixed. In this way, the multiple connection components 2 are fixed as a whole and remain stable.

[0033] The supporting connector 30 can be made of metal parts, such as SECC (Steel, Electrodeposition, Cold-rolled, Common, electro-galvanized cold steel plate), SGCC (Steel, Galvanized, Cold-rolled, Common, hot-dip galvanized cold steel plate), aluminum alloy or other stainless steel materials to ensure the strength of the supporting connector 30.

[0034] like Fig.10 As shown, in one embodiment, the number of supporting connectors 30 is two, one supporting connector 30 is detachably connected to the connecting component 2 of the first end 101 of the plurality of splicing units 10, and the other supporting connector 30 is detachably connected to the connecting component 2 of the second end 102 of the plurality of splicing units 10; thereby, the supporting connector 30 can fix both ends of the plurality of splicing units 10, so that the lamp panel 100 having the plurality of splicing units 10 can remain stable as a whole.

[0035] In this embodiment, since the glass substrate 11 is generally of low strength, the light board 100 in one embodiment of the present application may further include a support plate 40, which is disposed on a side of the glass substrate 11 away from the light-emitting unit 13; the support plate 40 is detachably connected to the two support connectors 30. For example, oppositely disposed card slots 33 are provided in the two support connectors 30, and the support connectors 30 are inserted into the card slots 33 to increase the overall structural strength of the light board 100 and avoid the risk of damage and breakage caused by bending in the thickness direction of the glass substrate 11. The support plate 40 may also be made of metal, and the material may be the same as that of the support connectors 30.

[0036] See also Figures 15 to 17 , Fig.15 is a schematic diagram of the structure of a connection assembly provided in an embodiment of the present application; Fig.16 is a structural schematic diagram of a first connecting member provided in an embodiment of the present application; Fig.17 It is a schematic diagram of the structure of the second connecting member provided in one embodiment of the present application.

[0037] like Figure 3 to Figure 4 , Figures 15 to 17 As shown, in one embodiment, one end of the connecting component 2 has a first plug-in hole 201, and the other end has a second plug-in hole 202; the connecting component 2 at the same end of two adjacent splicing units 10 is detachably connected through the first plug-in hole 201, the second plug-in hole 202 and the latch 203; the second plug-in hole 202 can be two arranged in parallel, and when plugged in, the first plug-in hole 201 is inserted between the two second plug-in holes 202, so that the two second plug-in holes 202 limit the first plug-in hole 201 in their arrangement direction, and further the first plug-in hole 201 and the second plug-in hole 202 are detachably connected through the latch 203 to fix the first plug-in hole 201 and the second plug-in hole 202.

[0038] like Figure 12 to Figure 14 As shown, in one embodiment, the surface of the supporting connector 30 has a first limiting portion 31 and a second limiting portion 32 that are spaced apart, the first limiting portion 31 has a third plug-in hole 311, the second limiting portion 32 has a fourth plug-in hole 321, and the connecting assembly 2 at the same end of the plurality of splicing units 10 is disposed between the first limiting portion 31 and the second limiting portion 32; so that the first limiting portion 31 and the second limiting portion 32 limit the connecting assembly 2 at the same end of the plurality of splicing units 10 within the range formed by the first limiting portion 31 and the second limiting portion 32.

[0039] For reference Figure 3 , Figure 4 as well as Figure 12 to Figure 14, the first plug hole 201 of the connection component 2 at the head end of the plurality of connection components 2 between the first limiting portion 31 and the second limiting portion 32 is detachably connected to the fourth plug hole 321 of the second limiting portion 32 through the latch 203, and the second plug hole 202 of the connection component 2 at the end is detachably connected to the third plug hole 311 of the first limiting portion 31 through the latch 203. Among them, the third plug hole 311 has the same structure and size as the first plug hole 201, and the fourth plug hole 321 has the same structure and size as the second plug hole 202, so that the first plug hole 201 is matched with the fourth plug hole 321 and the second plug hole 202 is matched with the third plug hole 311, thereby facilitating preparation and installation. It can be understood that the distance between the third plug hole 311 and the fourth plug hole 321 of the supporting connector 30 is the vertical distance between the center line of the third plug hole 311 and the center line of the fourth plug hole 321, which is also the vertical distance between the center line of the first plug hole 201 and the center line of the second plug hole 202 multiplied by the number of connecting components 2 at the same end of the glass substrate 11.

[0040] In a specific embodiment, the first limiting portion 31 and the second limiting portion 32 can be two protrusions (not marked in the figure) arranged on the surface of the supporting connector 30 close to the multiple connecting components 2 or arranged at the two ends of the supporting connector 30, and through holes are opened in the two protrusions to form the first plug-in hole 201 and the second plug-in hole 202 respectively. As long as the first limiting portion 31 and the second limiting portion 32 can be matched and connected with the first plug-in hole 201 and the second plug-in hole 202 of the connecting component 2 to achieve the effect of fixing the connecting component 2 at the same end of multiple splicing units 10, the present application does not limit the setting position of the first limiting portion 31 and the second limiting portion 32.

[0041] like Fig.11 As shown, in one embodiment, the connection component 2 has a slot 220, and one end of the light bar 1 is inserted into the slot 220 to be detachably connected to the connection component 2. Specifically, a cavity (not marked in the figure) is formed in the connection component 2, and the cavity forms the slot 220 into which one end of the light bar 1 can be inserted, and one end of the light bar 1 can be detachably connected to the connection component 2, such as plug-in connection, clip connection, etc.

[0042] like Figures 15 to 17As shown, in one embodiment, the connection assembly 2 may include: a first connection member 21 and a second connection member 22 that are detachably connected. The first connection member 21 and the second connection member 22 may be understood as one of the bottom connection member and the other of the top connection member. In this embodiment, the first connection member 21 is the bottom connection member and the second connection member 22 is the top connection member. The first connection member 21 includes a bottom plate 211 and two first side walls 212 connected to the bottom plate 211 and arranged opposite to each other. Both first side walls 212 have a groove 2121, which may be provided at the top of the first side wall 212, or at the top wall and inner surface of the first side wall 212. The second connection member 22 includes a top plate 221 and a lug 222 provided on the top plate 221. The lug 222 is correspondingly engaged with the groove 2121 to realize the detachable connection between the first connection member 21 and the second connection member 22, so that the first connection member 21 and the second connection member 22 can be easily disassembled. Furthermore, after the lug 222 is engaged with the groove 2121, the lug 222 can be fixed to the first side wall 212 by means of a screw 224, thereby improving the connection stability between the first connecting member 21 and the second connecting member 22. It can be understood that the groove 2121 is correspondingly provided with a first screw hole 21211, and the lug 222 is correspondingly provided with a second screw hole 2221.

[0043] In one embodiment, if Figures 11 to 17 As shown, a conductive member 223 is provided on the inner wall surface of the slot 220, for example, a conductive member 223 is provided on the top wall, side wall or bottom wall of the slot 220. One end of the conductive member 223 is electrically connected to the conductive layer 12, and the other end is exposed from the bottom of the slot 220 to form an exposed portion 2231, and the exposed portion 2231 is connected to the flexible circuit board 50. The exposed portion 2231 can be understood as a portion that is not provided in the slot 220 but is exposed through the gap between the slot 220 and the connecting component 2. The exposed portion 2231 can extend to an end of the connecting component 2 away from the light bar 1, so as to facilitate electrical connection with the flexible circuit board 50. In this embodiment, the conductive member 223 is provided on the inner wall of the second connecting member 22. It can be understood that in other embodiments, the conductive member 223 can also be provided on the inner wall of the first connecting member 21.

[0044] Furthermore, the exposed portion 2231 has a connection groove 22311, which can be understood as a groove 2121 opened in the exposed portion 2231 at the tail end of the conductive member 223. The conductive member 223 can be a metal member, and the connection groove 22311 is formed by opening the groove 2121 at the tail end of the metal member; or the conductive member 223 can also be a metal tube and a metal sheet welded or integrally formed, wherein the metal sheet portion is electrically connected to the conductive layer 12, and the opening of the metal tube forms the connection groove 22311.

[0045] In one embodiment, if Figures 11 to 17 As shown, the flexible circuit board 50 includes a plug-in section 501 and an extension section 502, and the plug-in section 501 is plugged into the connection groove 22311, that is, the plug-in section 501 of the flexible circuit board 50 is inserted into the connection groove 22311 to achieve electrical connection with the conductive member 223, and is electrically connected to the conductive layer 12 of the glass substrate 11 through the conductive member 223. The extension section 502 is arranged crosswise with the plug-in section 501, preferably vertically, and the extension section 502 extends along the thickness direction of the light board 100. The plug-in section 501 and the extension section 502 can be an integral structure, and the plug-in section 501 and the extension section 502 are formed by bending. By plugging and unplugging the flexible circuit board 50 and the conductive member 223, it is convenient to disassemble and assemble the flexible circuit board 50, so as to facilitate the repair or replacement of the damaged light bar 1. In other embodiments, the flexible circuit board 50 and the exposed portion 2231 of the conductive member 223 can also be connected by magnetic attraction or the like.

[0046] In a further embodiment, Figures 15 to 17 As shown, the first connector 21 may further include a second side wall 213, which is disposed on a side of the glass substrate 11 away from the port of the slot 220, and the second side wall 213 connects the two first side walls 212, so that the second side wall 213 can limit the position of the glass substrate 11 inserted into the slot 220, and can also protect the glass substrate 11. In addition, the height of the second side wall 213 is lower than the height of the first side wall 212, so that when the first connector 21 and the second connector 22 are clamped, there is still a certain gap (not marked in the figure) between the top plate 221 and the second side wall 213, so that the exposed portion 2231 of the conductive member 223 can extend from the gap to connect with the plug section 501.

[0047] In other embodiments, the first connecting member 21 and the second connecting member 22 may also be connected by magnetic attraction, bolt connection, or the like.

[0048] The material of the first connecting member 21 and the second connecting member 22 can be a plastic member, such as ABS (AcrylonitrileButadieneStyrene), PC (Polycarbonate), PP (Polypropylene), PMMA (PolymethylMethacrylate), etc. The first connecting member 21 and the second connecting member 22 are prepared by the above materials, so that the first connecting member 21 and the second connecting member 22 have good wear resistance and corrosion resistance, high chemical stability, and are easy to prepare.

[0049] In one embodiment, the surface of the bottom plate 211 close to the glass substrate 11 is provided with a first flexible layer 214; the surface of the top plate 221 close to the glass substrate 11 is provided with a second flexible layer 225. The first flexible layer 214 and the second flexible layer 225 can be made of rubber, silicone and other materials. The first flexible layer 214 and the second flexible layer 225 can be provided to protect the glass substrate 11, and provide a buffer when the glass substrate 11 is inserted into the slot 220, so as to avoid the glass substrate 11 directly contacting the rigid parts such as the top plate 221 and the bottom plate 211, thereby causing the glass substrate 11 to be damaged. The conductive member 223 and the second flexible layer 225 are arranged at intervals to avoid mutual influence between the two, resulting in the problem of poor contact of the conductive member 223.

[0050] Furthermore, two second flexible layers 225 are provided on the surface of the top plate 221 close to the glass substrate 11, and the two second flexible layers 225 are respectively provided on opposite sides of the conductive member 223. One end of the two second flexible layers 225 close to the port of the slot 220 exceeds the other end of the conductive member 223 close to the port of the slot 220, that is, the distance H1 between the second flexible layer 225 and the port of the slot 220 is less than the distance H2 between the conductive member 223 and the port of the slot 220, so that when the glass substrate 11 is inserted into the slot 220, the glass substrate 11 can first contact with the two second flexible layers 225, thereby protecting the glass substrate 11 and preventing the top plate 221 and the bottom plate 211 made of rigid materials from causing damage to the glass substrate 11. At the same time, in this embodiment, the thickness of the conductive member 223 relative to the top plate 221 is greater than the thickness of the second flexible layer 225 relative to the top plate 221, thereby facilitating the connection of the conductive member 223 with the conductive layer 12 and the flexible circuit board 50.

[0051] In order to solve the above problems, the present application also provides a display device.

[0052] See also Fig.18 , Fig.18 It is a schematic diagram of the structure of a display device provided in one embodiment of the present application.

[0053] The display device 300 provided in the present application includes a display panel 301 , a backlight module 302 and a back plate (not shown). The backlight module 302 is electrically connected to the display panel 301 to provide a light source for the display panel 301 .

[0054] In one embodiment, the display panel 301 may be a liquid crystal display panel (LCD), an LED display panel or an OLED display panel. The liquid crystal display panel may include an opposing substrate 3011, an array substrate 3012 and a liquid crystal layer 3013 disposed between the opposing substrate 3011 and the array substrate 3012. The liquid crystal layer 3013 may include a plurality of liquid crystal molecules 3014. The opposing substrate 3011 may specifically be a color film substrate.

[0055] The backlight module 302 may include a light board 100 , and the light board 100 is any of the light boards 100 described above. The light board 100 includes a plurality of splicing units 10 spliced ​​to each other. Please refer to the aforementioned content, which will not be described again here.

[0056] When the light board 100 displays white light and is used as a backlight module 302, each color resistor includes at least one group of red, green and blue sub-pixel units. In this embodiment, the color resistor can be composed of three light-emitting diodes of different colors, red, green and blue, and the light board 100 cooperates with the color film substrate to perform color display of the display device 300. Alternatively, the color resistor can also include a light-emitting unit 13 of the same color and a light conversion unit (not shown in the figure). The light conversion unit can be phosphors of three different colors, red, green and blue. By coating the phosphors of three different colors, red, green and blue, on a plurality of light-emitting units 13 of the same color, the light-emitting units 13 of the same color are converted into red, green and blue sub-pixel units of different colors, thereby meeting the color display requirements of the display device 300.

[0057] In one embodiment, the light board 100 can be set on the back panel by means of screws 224 or welding. The light board 100 formed by splicing a plurality of light strips 1 is used as the display screen of the display device 300. For example, the light strips 1 are spliced ​​and designed, so that the number of spliced ​​light strips 1 can be adjusted according to display devices 300 of different sizes. There is no need to redevelop and design the display screen of the display device 300 separately, thereby effectively solving the problem of repeated development and design, realizing the sharing of the light strips 1, saving processes and costs, and improving the efficiency of glass use. At the same time, since the glass substrate 11 has no expansion and contraction problem, there is no gap in the middle of the spliced ​​display screen, and it will not expand due to heat, and will not affect the display effect of the display screen. Therefore, the display effect of the spliced ​​display screen is equivalent to that of a display screen formed by a whole piece of glass, thereby improving the glass utilization rate without affecting the display effect and user experience of the display screen.

[0058] In addition, by fixing a plurality of light bars 1 at intervals on the back plate, a light plate 100 of a direct-type backlight module 302 can be formed, thereby improving the utilization rate of the light bars 1 .

[0059] The light board disclosed in the present application includes a plurality of splicing units, and the splicing units include a light bar and a connecting component. The light bar includes a glass substrate, a conductive layer arranged on the surface of the glass substrate, and a plurality of light-emitting units; wherein the conductive layer is electrically connected to the light-emitting unit; the connecting component is arranged at the end of the glass substrate and is detachably connected to the light bar; wherein the connecting components at the same end of the plurality of splicing units are detachably connected. The detachable connection between the plurality of connecting components in the present application is different from the integrated or welded connecting components in the prior art. The detachable connection between the plurality of connecting components allows each light bar to be relatively independent. If the light bar of one of the plurality of splicing units fails or is damaged, the splicing unit can be disassembled, and the corresponding light bar or corresponding connecting component of the splicing unit can be repaired or replaced, so that a single light bar can be replaced without replacing the entire light board, saving product production costs and maintenance costs. At the same time, the manufacturing process is greatly simplified, which helps to improve the manufacturing yield of the light bar and thus reduce costs.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
