DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0037] The terms "first", "second", etc. in the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include at least one of the features.

For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0038] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all directed to the same embodiment, or to a single alternative embodiment. One of ordinary skill in the art will readily recognize from the disclosure herein a wide number of variations and modifications.

[0039] In the related art, a lamp strip made of a glass substrate is connected to an external power source through welding of a connector or a circuit board to form a conductive point for lighting, so that the lamp strip and the connector form an integrated structure. When one lamp strip is damaged, the entire lamp panel needs to be replaced, resulting in high product maintenance cost, and it is inconvenient to replace and maintain a single lamp strip.

[0040] To solve the above problems, the application provides a lamp panel and a display device.

[0041] Please refer to Figures 1 to 9 , Figure 1 is a structural schematic diagram provided by the application; Figure 1 is a three-dimensional structural schematic diagram of a lamp panel provided by an embodiment of the application; wherein the positive electrode and the negative electrode of the conductive layer are arranged at two ends of the glass substrate; Figure 2 is Figure 1 a structural schematic diagram of a lamp strip provided by the application; Figure 3 is Figure 1 a structural enlarged schematic diagram of part A in Figure 4 is Figure 1 a structural enlarged schematic diagram of part B in Figure 5 is a three-dimensional structural schematic diagram of a lamp panel provided by another embodiment of the 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 is Figure 5 a structural schematic diagram of a lamp strip provided by the application; Figure 7 is Figure 5 a structural enlarged schematic diagram of part C in Figure 8 is a three-dimensional structural schematic diagram of a lamp panel provided by still another embodiment of the 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; Figure 9 is Figure 8 a structural schematic diagram of a lamp strip provided by the application.

[0042] As Figures 1 to 9As shown, the light panel 100 provided in this application includes multiple splicing units 10. Each splicing unit 10 includes a light strip 1 and a connecting component 2. The light strip 1 includes a glass substrate 11, a conductive layer 12 disposed on the surface of the glass substrate 11, and multiple light-emitting units 13. The conductive layer 12 is electrically connected to the light-emitting units 13. The light-emitting units 13 can be LEDs, mini LEDs, or micro LEDs, etc., and this application does not limit them. It can be understood that the light panel 100 formed by splicing multiple splicing units 10 can be used for direct-lit backlight modules or side-lit backlight modules.

[0043] The conductive layer 12 can be electrically connected to the flexible printed circuit board 50 (FPC) via the connecting component 2. The conductive layer 12 includes a positive electrode 121 and a negative electrode 122, which can be disposed at the same end or opposite ends of the glass substrate 11.

[0044] In one embodiment, such as Figures 1 to 4 As shown, positive electrode 121 and negative electrode 122 are respectively disposed at both ends of glass substrate 11. Flexible circuit board 50 is disposed at both ends of glass substrate 11. The positive electrode (not shown) of one flexible circuit board 50 is connected to the positive electrode 121 of conductive layer 12, and the negative electrode (not shown) of the other flexible circuit board 50 is connected to the negative electrode 122 of conductive layer 12 to form a driving circuit.

[0045] In another embodiment, such as Figures 5 to 9 As shown, with the positive electrode 121 and negative electrode 122 disposed at the same end of the glass substrate 11, a flexible circuit board 50 can be disposed at only one end of the glass substrate 11. The positive electrode of the flexible circuit board 50 is connected to the positive electrode 121 of the conductive layer 12, and the negative electrode of the flexible circuit board 50 is connected to the negative electrode 122 of the conductive layer 12 to form a driving circuit. When the positive electrode 121 and negative electrode 122 of the conductive layer 12 are disposed at the same end of the glass substrate 11, the number of flexible circuit boards 50 can be reduced, thus lowering the manufacturing cost of the lamp board 100.

[0046] The connecting component 2 is disposed at the end of the glass substrate 11 and is detachably connected to the light strip 1. The detachable connection between the connecting component 2 and the light strip 1 allows for easy repair or replacement of any damaged light strip 1 or connecting component 2, and also facilitates the installation of the connecting component 2 and the light strip 1. The connecting component 2 can fix the glass substrate 11 on one hand, and conduct electricity between the conductive layer 12 and the external circuit (e.g., the flexible circuit board 50) on the other hand, forming the driving circuit of the light-emitting unit 13.

[0047] In one embodiment, each splicing unit 10 may include one, two, or more light strips 1. For example...Figures 8 to 9 As shown, when two rows or more rows of light bars 1 are clamped by a single connecting assembly 2, the number of connecting assemblies 2 can be greatly reduced, the cost can be reduced, the installation time of the connecting assembly 2 can be reduced, and the assembly efficiency can be improved, compared with the case that a single connecting assembly 2 clamps only one row of light bars 1.

[0048] The connecting assemblies 2 at the same end of the plurality of splicing units 10 are detachably connected. When the plurality of light bars 1 are spliced, the end of each light bar 1 is provided with a connecting assembly 2, and the plurality of connecting assemblies 2 at the same end of each light bar 1 are detachably connected. The detachable connection between the plurality of connecting assemblies 2 is different from the integral or welded connecting assembly 2 in the prior art. The detachable connection between the plurality of connecting assemblies 2 allows each light bar 1 to be relatively independent. If the light bar 1 of one splicing unit 10 in the plurality of splicing units 10 fails or is damaged, the splicing unit 10 can be disassembled, and the corresponding light bar 1 or the corresponding connecting assembly 2 of the splicing unit 10 can be repaired or replaced, so that the single light bar 1 can be replaced, the entire lamp panel 100 does not need to be replaced, the product production cost and maintenance cost are saved. During installation, the single connecting assembly 2 is first installed at the end of the light bar 1, and then the plurality of connecting assemblies 2 are assembled to form a whole lamp panel 100. Compared with the whole direct type glass substrate 11, the process technology is greatly simplified, which helps to improve the manufacturing yield of the light bar 1, and thus reduces the cost.

[0049] Please refer to Figures 10 to 14 , Figure 10 is a side view structural schematic diagram of a lamp panel provided by an embodiment of the present application; Figure 11 is Figure 10 is an enlarged structural schematic diagram of part D in FIG. 8; Figure 12 is a structural schematic diagram of a support connecting piece provided by an embodiment of the present application; Figure 13 is Figure 12 is an enlarged structural schematic diagram of part E in FIG. 9; Figure 14 is Figure 12 is an enlarged structural schematic diagram of part F in FIG. 10.

[0050] As Figures 1 to 4 , Figures 10 to 14As shown in the drawings, in an embodiment, the lamp panel 100 can further comprise a support connecting piece 30, which is detachably connected with the connecting assembly 2 of the same end of the plurality of splicing units 10. For example, each splicing unit 10 comprises two end portions, i.e., a first end portion 101 and a second end portion 102, the first end portions 101 of the plurality of splicing units 10 are the same end, and the second end portions 102 of the plurality of splicing units 10 are also the same end; the support connecting piece 30 can be detachably connected with the first end portions 101 of the plurality of splicing units 10 or the second end portions 102 of the plurality of splicing units 10. The support connecting piece 30 and the connecting assembly 2 of the same end of the plurality of splicing units 10 can be detachably connected through clamping, magnetic attraction, and bolt 203 connection, etc. The support connecting piece 30 can support the same end of the plurality of splicing units 10, which can prevent the bending, rotation, displacement, etc. between the plurality of detachably connected connecting assemblies 2, so that the plurality of detachably connected connecting assemblies 2 can be relatively fixed, and the plurality of connecting assemblies 2 are fixed as a whole and kept stable through this way.

[0051] The support connecting piece 30 can be made of metal, such as SECC (Steel, Electrodeposition, Cold-rolled, Common), SGCC (Steel, Galvanized, Cold-rolled, Common), aluminum alloy, or other stainless steel materials, etc., to ensure the strength of the support connecting piece 30.

[0052] As shown in the drawings, Figure 10 In an embodiment, the number of the support connecting piece 30 is two, one support connecting piece 30 is detachably connected with the connecting assembly 2 of the first end portion 101 of the plurality of splicing units 10, and the other support connecting piece 30 is detachably connected with the connecting assembly 2 of the second end portion 102 of the plurality of splicing units 10; so that the support connecting piece 30 can fix both ends of the plurality of splicing units 10, and the lamp panel 100 with the plurality of splicing units 10 can be kept stable as a whole.

[0053] In this embodiment, since the glass substrate 11 generally has low strength, the lamp panel 100 in an embodiment of the present application can further comprise a support plate 40, which is arranged on the side of the glass substrate 11 away from the light-emitting unit 13; the support plate 40 is detachably connected with the two support connecting pieces 30. For example, the two support connecting pieces 30 are provided with oppositely arranged clamping grooves 33, and the support connecting pieces 30 are inserted into the clamping grooves 33, so as to increase the overall structural strength of the lamp panel 100, and avoid the risk of breakage and fracture caused by bending in the thickness direction of the glass substrate 11; the support plate 40 can also be made of metal, and the material can be the same as that of the support connecting piece 30.

[0054] Please refer to Figures 15 to 17 , Figure 15 is a structural schematic diagram of a connecting assembly provided by an embodiment of the present application; Figure 16 is a structural schematic diagram of a first connecting piece provided by an embodiment of the present application; Figure 17 is a structural schematic diagram of a second connecting piece provided by an embodiment of the present application.

[0056] As Figures 12 to 14 shown, in an embodiment, the surface of the support connecting piece 30 has a first limiting part 31 and a second limiting part 32 arranged at intervals, the first limiting part 31 has a third insertion hole 311, the second limiting part 32 has a fourth insertion hole 321, and the connecting assemblies 2 of the same end of a plurality of splicing units 10 are arranged between the first limiting part 31 and the second limiting part 32; so that the first limiting part 31 and the second limiting part 32 limit the connecting assemblies 2 of the same end of the plurality of splicing units 10 within the range formed by the first limiting part 31 and the second limiting part 32.

[0057] Please refer to Figure 3 , Figure 4 and Figures 12 to 14The first insertion hole 201 of the connection assembly 2 at the head end between the first limiting part 31 and the second limiting part 32 is detachably connected with the fourth insertion hole 321 of the second limiting part 32 through the pin 203, and the second insertion hole 202 of the connection assembly 2 at the tail end is detachably connected with the third insertion hole 311 of the first limiting part 31 through the pin 203. The third insertion hole 311 and the first insertion hole 201 are of the same structure and size, and the fourth insertion hole 321 and the second insertion hole 202 are of the same structure and size, so that the first insertion hole 201 and the fourth insertion hole 321 are matched and connected, and the second insertion hole 202 and the third insertion hole 311 are matched and connected, thereby facilitating the preparation and installation. It can be understood that the distance between the third insertion hole 311 and the fourth insertion hole 321 of the support connecting piece 30 is the vertical distance between the center line of the third insertion hole 311 and the center line of the fourth insertion hole 321, and is also the vertical distance between the center line of the first insertion hole 201 and the center line of the second insertion hole 202 multiplied by the number of the connection assemblies 2 at the same end of the glass substrate 11.

[0058] In an embodiment, the first limiting part 31 and the second limiting part 32 can be two protrusions (not shown) arranged on the surface of the support connecting piece 30 close to the plurality of connection assemblies 2 or arranged on the two end portions of the support connecting piece 30. The first insertion hole 201 and the second insertion hole 202 are formed by arranging through holes in the two protrusions, as long as the first limiting part 31 and the second limiting part 32 can be matched and connected with the first insertion hole 201 and the second insertion hole 202 of the connection assembly 2 to achieve the effect of fixing the connection assemblies 2 at the same end of the plurality of spliced units 10, and the application does not limit the arrangement position of the first limiting part 31 and the second limiting part 32.

Specifically, a cavity (not shown) is formed in the connection assembly 2, and the cavity forms the slot 220 into which one end of the light bar 1 is inserted. One end of the light bar 1 can be detachably connected with the connection assembly 2, for example, plug-in connection, clamping, etc.

By plugging and unplugging the flexible circuit board 50 and the conductive element 223, it is easy to disassemble and assemble the flexible circuit board 50, thereby facilitating the repair or replacement of damaged lamp strips 1. In other embodiments, the exposed portion 2231 of the flexible circuit board 50 and the conductive element 223 can also be connected by magnetic attraction or other means.

[0064] In a further embodiment, such as Figures 15 to 17 As shown, the first connector 21 may further include a second sidewall 213. The second sidewall 213 is disposed on the side of the glass substrate 11 away from the port of the slot 220, and the second sidewall 213 connects the two first sidewalls 212. This allows the second sidewall 213 to limit the position of the glass substrate 11 when it is inserted into the slot 220, and also to protect the glass substrate 11. In addition, the height of the second sidewall 213 is lower than the height of the first sidewall 212, so that when the first connector 21 and the second connector 22 are engaged, there is still a certain gap (not shown in the figure) between the top plate 221 and the second sidewall 213, so that the exposed part 2231 of the conductive member 223 can extend out from the gap and connect with the insertion section 501.

[0065] In other embodiments, the first connector 21 and the second connector 22 can also be connected by magnetic attraction, bolt connection or other means.

[0066] The first connector 21 and the second connector 22 can be made of plastic, such as ABS (Acrylonitrile Butadiene Styrene), PC (Polycarbonate), PP (Polypropylene), PMMA (Polymethyl Methacrylate), etc. Using these materials to prepare the first connector 21 and the second connector 22 results in good wear resistance and corrosion resistance, high chemical stability, and ease of fabrication.

[0067] In an embodiment, the bottom plate 211 is provided with a first flexible layer 214 close to the surface of the glass substrate 11; the top plate 221 is provided with a second flexible layer 225 close to the surface of the glass substrate 11, and the first flexible layer 214 and the second flexible layer 225 can be made of rubber, silica gel or the like. By providing the first flexible layer 214 and the second flexible layer 225, the glass substrate 11 can be protected, and the glass substrate 11 can be buffered when inserted into the slot 220, so as to avoid the glass substrate 11 from being damaged due to direct contact with the rigid parts such as the top plate 221 and the bottom plate 211. The conductive part 223 is arranged in a spaced manner with the second flexible layer 225, so as to avoid mutual influence between the two, and to avoid the problem of poor contact of the conductive part 223.

[0068] Further, the top plate 221 is provided with two second flexible layers 225 close to the surface of the glass substrate 11, and the two second flexible layers 225 are arranged on opposite sides of the conductive part 223. One end of the two second flexible layers 225 close to the port of the slot 220 is beyond one end of the conductive part 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 part 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 the two second flexible layers 225, thereby protecting the glass substrate 11 and avoiding damage to the glass substrate 11 caused by the rigid materials of the top plate 221 and the bottom plate 211. Meanwhile, in the embodiment, the thickness of the conductive part 223 relative to the top plate 221 is greater than the thickness of the second flexible layer 225 relative to the top plate 221, so as to facilitate the connection of the conductive part 223 with the conductive layer 12 and the flexible circuit board 50.

[0069] To solve the above problems, the application further provides a display device.

[0070] Please refer to Figure 18 , Figure 18 is a structural schematic diagram of a display device provided by an embodiment of the application.

[0071] The display device 300 provided by the application includes a display panel 301, a backlight module 302 and a back plate (not shown in the figure), the backlight module 302 is electrically connected with the display panel 301, and is used for providing a light source for the display panel 301.

[0072] In an embodiment, the display panel 301 can be a liquid crystal display panel (LCD, Liquid Crystal Display), an LED display panel or an OLED display panel. The liquid crystal display panel can include a color filter substrate 3011, an array substrate 3012 and a liquid crystal layer 3013 arranged between the color filter substrate 3011 and the array substrate 3012, and the liquid crystal layer 3013 can include a plurality of liquid crystal molecules 3014.

[0073] The backlight module 302 can comprise the lamp panel 100, which is any of the lamp panels 100 described above, and the lamp panel 100 comprises a plurality of spliced units 10 spliced with each other. Please refer to the foregoing description, which will not be repeated here.

[0074] When the lamp panel 100 displays white light as the backlight module 302, each color block comprises at least one group of red, green and blue sub-pixel units. In this embodiment, the color block can be composed of red, green and blue light-emitting diodes of three different colors. The lamp panel 100 cooperates with the color film substrate to perform color display of the display device 300. Alternatively, the color block can also comprise the same-color light-emitting unit 13 and a light conversion unit (not shown in the figure). The light conversion unit can be red, green and blue fluorescent powder. By coating red, green and blue fluorescent powder of three different colors on the same-color light-emitting unit 13, the same-color light-emitting unit 13 is converted into red, green and blue sub-pixel units of different colors, thereby meeting the color display requirements of the display device 300.

[0075] In an embodiment, the lamp panel 100 can be arranged on the back plate by screws 224 or welding, etc. The lamp panel 100 formed by splicing a plurality of lamp strips 1 serves as the display screen of the display device 300. For example, the lamp strips 1 are designed to be spliced, which can facilitate the adjustment of the number of spliced lamp strips 1 according to display devices 300 of different sizes, and there is no need to separately develop and design the display screen of the display device 300, thereby effectively solving the problem of repeated development and design, realizing the sharing of the lamp strips 1, saving the process and cost, and improving the utilization efficiency of the glass. At the same time, since the glass substrate 11 has no expansion and contraction problem, there is no gap in the middle of the display screen formed by splicing, and the display screen will not be affected by thermal expansion, and the display effect of the display screen will not be affected. Therefore, the display effect of the display screen formed by splicing is equivalent to that of the display screen formed by a whole piece of glass, thereby improving the utilization rate of the glass, and not affecting the display effect and use experience of the display screen.

[0076] In addition, the plurality of lamp strips 1 are fixed on the back plate at intervals, and the lamp panel 100 of the direct type backlight module 302 can also be formed, thereby improving the utilization rate of the lamp strips 1.

[0077] The lamp panel disclosed in the application comprises a plurality of splicing units, the splicing unit comprises a lamp strip and a connecting assembly, the lamp strip comprises 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 with the light emitting units; the connecting assembly is arranged at the end of the glass substrate and is detachably connected with the lamp strip; wherein the connecting assemblies at the same end of the plurality of splicing units are detachably connected. The detachable connection between the plurality of connecting assemblies is different from the integral or welded connecting assembly in the prior art. The detachable connection between the plurality of connecting assemblies makes each lamp strip relatively independent. If the lamp strip of one splicing unit in the plurality of splicing units fails or is damaged, the splicing unit can be disassembled, and the corresponding lamp strip or the corresponding connecting assembly of the splicing unit can be repaired or replaced, so that the single lamp strip can be replaced, the overall lamp panel does not need to be replaced, and the production cost and maintenance cost of the product are saved. At the same time, the process technology is greatly simplified, which helps to improve the production yield of the lamp strip and thus reduces the cost.
