[0042] In order to illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and examples.

[0043] Please refer to Figures 1 to 3 The first embodiment of the present application provides a lamp panel 100, which comprises a first circuit board 5 and a plurality of light emitting elements 6; wherein the first surface 57 of the first circuit board 5, defined as the front surface of the first circuit board 5, is provided with a plurality of first mounting positions and a plurality of second mounting positions (both not shown) for mounting the light emitting elements 6, and the second surface 58 of the first circuit board 5, defined as the back surface of the first circuit board 5, is provided with a plurality of first pads 54; please refer to Figure 3 The distance between adjacent first mounting positions is a first distance d1, and the distance between adjacent second mounting positions is a second distance d2. Each light emitting element 6 is arranged in the first mounting position or the second mounting position. Please refer to Figure 1 When the light emitting elements 6 are respectively mounted in the first mounting positions, the light emitting elements 6 can form electrical connections with the first pads 54, and the distance between adjacent two light emitting elements 6 is the first distance d1; please refer to Figure 2 When the light emitting elements 6 are respectively mounted in the second mounting positions, the light emitting elements 6 can form electrical connections with the first pads 54, and the distance between adjacent two light emitting elements 6 is the second distance d2. The first distance d1 is greater than or equal to 0, and the second distance d2 is greater than the first distance d1.

[0044] The lamp panel 100 in the present embodiment can arrange the light emitting elements 6 according to the first distance d1 or the second distance d2, which allows the lamp panel 100 to be spliced according to different seam gaps, and when the lamp panel 100 is spliced according to different seam gaps and two display panels 200 with different sizes are obtained, the distance between any two adjacent light emitting elements 6 on the entire display panel 200 can be equal. This includes, please refer to Figure 5 and Figure 6As shown, the lamp panels 100 are spliced according to a first joint gap D1, the distance between two light emitting elements 6 close to each other on two adjacent lamp panels 100 is a first distance d1, and the distance between two light emitting elements 6 on the same lamp panel 100 is also the first distance d1. At this time, the display panel 200 obtained has a first size. As shown in Figure 7 and Figure 8 As shown, the lamp panels 100 are spliced according to a second joint gap D2, the distance between two light emitting elements 6 close to each other on two adjacent lamp panels 100 is a second distance d2, and the distance between two light emitting elements 6 on the same lamp panel 100 is also the second distance d2. At this time, the display panel 200 obtained has a second size. The first joint gap D1 is greater than or equal to 0, and the second joint gap D2 is not equal to the first joint gap D1.

[0045] The lamp panel 100 in the embodiment can have light emitting elements 6 arranged at different positions on the front surface of the first circuit board 5, realizing at least two different spacing arrangement modes. Thus, by splicing the lamp panels 100 according to different joint gaps, at least two display panels 200 of different sizes can be obtained, and the light emitting elements 6 on each display panel 200 of each size are uniformly arranged. This makes display panels 200 of different sizes be able to be combined by lamp panels 100 of the same size, expands the flexibility of splicing and assembling the display panel 200, reduces the processing and manufacturing difficulty and work repetition of the large-size display panel 200, and also reduces the production cycle to a certain extent. The versatility of the lamp panel 100 and the first circuit board 5 is improved, the design, processing and manufacturing of a large number of lamp panels 100 of different sizes are reduced, and the overall production cost is reduced.

[0046] Two display panels 200 of adjacent sizes, for example, 85-inch and 86-inch display panels 200, can be spliced by using lamp panels 100 of the same size; 98-inch and 100-inch display panels 200 can be spliced by using lamp panels 100 of the same size.

[0047] It should be further noted that the two display panels 200 of adjacent sizes are not limited, and when the distance between the light emitting elements 6 meets the division of the first distance d1 and the second distance d2, the two display panels 200 of non-adjacent sizes can also be spliced by using lamp panels 100 of the same size but different numbers.

[0048] The light emitting element 6 can be an LED (Light-emitting Diode), or other types of light emitting elements. The size of the light emitting element 6 is not limited.

[0049] The first circuit board 5 can be a flexible circuit board, or a hard circuit board, such as a glass-based circuit board, an aluminum-based circuit board, etc.

[0050] The light emitting elements 6 are distributed in a two-dimensional array on the front surface of the first circuit board 5. The form of the array can not be limited and can meet the display requirements. For example Figure 1 and Figure 2 As shown in FIGS. 1 and 2, the light emitting elements 6 are arranged in a rectangular array along the first direction and the second direction perpendicular to each other. Then, the first distance d1 between any two adjacent light emitting elements 6 includes the distance between the two light emitting elements 6 along the first direction and the distance along the second direction.

[0051] In an optional embodiment, the distance between any two adjacent light emitting elements 6 along the first direction and the distance along the second direction are equal on the lamp panel 100, both of which are d1 or d2. The following description and drawings of the present application are based on this as an example.

[0052] The plurality of lamp panels 100 are spliced into the display panel 200 according to different joint gaps. When the lamp panels 100 are directly fixed to the desired position and constitute the display panel 200, for example, on a wall, whether the joint gap between the lamp panels 100 is 0 or greater than 0, the lamp panels 100 can be connected to other retaining structures (not shown) for assisting the corresponding joint gap between the two lamp panels 100, or can be without the retaining structure. When the display panel 200 spliced by the lamp panels 100 is an independent delivery product, installed according to user requirements, the lamp panels 100 can be optionally connected to the retaining structure, especially when the joint gap between the lamp panels 100 is greater than 0.

[0053] The shape of the first circuit board 5 is not limited and can be rectangular or other shapes, as long as it can facilitate the design of mounting sites with different distances.

[0054] In an optional embodiment, the shape of the first circuit board 5 is square, and the first mounting sites and the second mounting sites are arranged in N×N, where N is an integer greater than 0. Such a first circuit board 5 is beneficial to the fine adjustment arrangement between the mounting sites and has better adaptability to display panels 200 of different sizes. For example Figure 1 and Figure 2 As shown in FIGS. 3 and 4, taken N=3 as an example, the first mounting site and the second mounting site at the center coincide.

[0055] Not limited to square, in other optional embodiments, the first circuit board 5 can have other shapes. In other optional embodiments, the first mounting sites and the second mounting sites can also be arranged in other forms, for example, the first mounting sites are arranged in N×N, and the second mounting sites are arranged in M×M, where N and M are integers greater than 0, and N and M are not equal.

[0056] The first mounting position and the second mounting position refer to two regions on the front surface of the first circuit board 5, i.e. at least part of the regions covered by the light emitting elements 6. On any one region, a first marking structure 53 can be provided to assist the workers to quickly and accurately mount the light emitting elements 6 in place.

[0057] In one embodiment, the first marking structure 53 provided on the first surface 57 comprises a first indicating line for indicating the first mounting position, and a second indicating line for indicating the second mounting position. The marking lines can be formed by printing, spraying, or can be formed by a layer structure during the manufacturing of the first circuit board 5.

[0058] For example, the first indicating line and the second indicating line are both cross lines, Figure 1 and Figure 2 In the above, the first indicating line and the second indicating line are both shown as dotted lines, and the center intersection of the cross lines is used to indicate the center position of the light emitting element 6. In this way, the distance between the two center intersections can define the distance between the light emitting elements 6. Alternatively, the first indicating line and the second indicating line are both dots, which are used to indicate the positions of the two pins of the light emitting element 6, or the center position of the light emitting element 6, etc.

[0059] In other alternative embodiments, the first marking structure 53 can be a groove and / or a protrusion formed on the first circuit board 5. The first marking structure 53 is preferably arranged so as not to significantly affect the normal display of the panel.

[0060] In other alternative embodiments, the first marking structure 53 can only comprise the first marking line, or only comprise the second marking line.

[0061] More specific implementation forms of the first marking structure 53 will not be listed one by one, as long as they can prompt and position the mounting of the light emitting element 6.

[0062] The first pads 54 are located on the back surface of the first circuit board 5, and the light emitting element 6 emits light on the front surface of the first circuit board 5. Therefore, the first circuit board 5 is provided with a through hole (not shown) for the pins of the light emitting element 6 to pass through. Alternatively, the first circuit board 5 is provided with two through holes corresponding to each first mounting position and second mounting position.

[0063] Please refer to Figure 4 In one embodiment, the first pads 54 comprise two positive pads 541 and two negative pads 542, the two positive pads 541 are connected in parallel, and the two negative pads 542 are connected in parallel. One positive pad 541 and one negative pad 542 correspond to the first mounting position, and the other positive pad 541 and the other negative pad 542 correspond to the second mounting position.Figure 4 In the embodiment, the positive electrode pads are represented by circular solid points, and the negative electrode pads are represented by triangular solid points. When the light emitting element 6 is installed in the first installation position, its two pins can be connected to one positive electrode pad 541 and one negative electrode pad 542 through two through holes respectively, and when the light emitting element 6 is installed in the second installation position, its two pins are connected to another positive electrode pad 541 and another negative electrode pad 542 through another two through holes respectively. The purpose of such design is that the positions of the positive electrode pads 541 and the negative electrode pads 542 can be as close as possible to the corresponding through holes, and after the pins of the light emitting element 6 pass through, they directly reach the first pads 54 without the need for a long extension distance.

[0064] Alternatively, in an optional embodiment, the first pads 54 include one positive electrode pad 541 and one negative electrode pad 542, and the first circuit board 5 is provided with two through holes corresponding to each first installation position and each second installation position, and the two pins of the light emitting element 6 can be connected to the positive electrode pad 541 and the negative electrode pad 542 through the two through holes. That is, when the light emitting element 6 is installed in the first installation position, its two pins can be connected to the positive electrode pad 541 and the negative electrode pad 542 through two through holes respectively, and when the light emitting element 6 is installed in the second installation position, its two pins can be connected to the positive electrode pad 541 and the negative electrode pad 542 through another two through holes respectively. In this embodiment, the number of positive electrode pads 541 and negative electrode pads 542 can be reduced, and the manufacturing of the first circuit board 5 is simplified.

[0065] It should be noted that, Figure 4 In the embodiment, the first mark line 531 and the second mark line 532 are shown on the second surface 58 of the first circuit board 5, which does not mean that the first mark line 531 and the second mark line 532 must be provided on the second surface 58. Here, they are only used to represent the corresponding relationship between the first mark line 531 and the second mark line 532 and the positive electrode pads 541 and the negative electrode pads 542.

[0066] Between the first pads 54 on the entire lamp panel 100, they can be sequentially connected in series, as shown in Figure 4 The multiple first pads 54 are sequentially connected through the traces 56, and the solid straight lines on the second surface 58 represent the traces 56; alternatively, the first pads 54 can be all connected in parallel; or the first pads 54 can also be connected in a combination of series and parallel, for example, nine first pads 54 can be connected in a manner of three in series and three in parallel.

[0067] Please refer to Figure 4As shown, in one embodiment, the lamp board 100 further includes a second pad 55, which is electrically connected to each of the first pads 54 via a trace 56. The second pad 55 of one lamp board 100 is used to connect with the second pads 55 of adjacent lamp boards 100, which can be connected in series or in parallel, thereby forming an electrical connection between adjacent lamp boards 100.

[0068] Optionally, such as Figure 3 and Figure 4 As shown, the second pad 55 is located on the side of the first circuit board 5 and is flush with or recessed relative to the side of the first circuit board 5. The purpose of this arrangement is that the second pad 55 will not protrude from the edge of the first circuit board 5. When the two lamp boards 100 are spliced, the second pad 55 will not occupy the splicing gap between the two lamp boards 100, thereby enabling splicing of the two lamp boards 100 with small gaps or even without gaps.

[0069] Please refer to the following: Figures 5 to 8 As shown, this application embodiment also provides a display panel 200, which includes a plurality of light panels 100 as described in the above embodiments, wherein the plurality of light panels 100 are spliced ​​together, and the distance between two light-emitting elements 6 that are close to each other on two adjacent light panels 100 is equal to the distance between two adjacent light-emitting elements 6 on one light panel 100.

[0070] The display panel 200 provided in this application embodiment is spliced ​​from the aforementioned general-purpose lamp board 100, which has high assembly flexibility, reduces the processing and manufacturing difficulty of large-size display panels 200, reduces a large number of similar designs, processing and manufacturing of wiring, and reduces overall production costs.

[0071] See Figure 6 Hehe Figure 8 As shown, in one embodiment, the display panel 200 further includes a second circuit board 9, with each lamp board 100 spliced ​​on the surface of the second circuit board 9 and electrically connected to the second circuit board 9. Specifically, the second circuit board 9 is provided with a plurality of third pads 91, and the lamp board 100 can form an electrical connection with the third pads 91 of the second circuit board 9 through its second pads 55.

[0072] The second circuit board 9 can be a flexible circuit board or a rigid circuit board, such as a glass-based circuit board or an aluminum-based circuit board.

[0073] In one alternative embodiment, the edge of the second circuit board 9 may be flush with the outermost edge of each lamp panel 100 after splicing, or the edge of the second circuit board 9 may be relatively concave or convex. This depends on the edge design requirements of the display panel 200.

[0074] In one specific embodiment, the edge of the second circuit board 9 is flush with the outermost edge of the assembled lamp panels 100, or the edge of the second circuit board 9 protrudes relatively. That is to say, in this case, the size of the display panel 200 is determined by the size of the second circuit board 9.

[0075] For example, please see Figure 6 As shown, the second circuit board 9 has the same dimensions as the first circuit board. Multiple lamp panels 100 are disposed on the surface of the second circuit board 9, with a first seam gap D1 maintained between the lamp panels 100. At this time, the edge of the second circuit board 9 is flush with the outermost edge of the lamp panel 100. (See also...) Figure 8 As shown, the second circuit board 9 has a second dimension, and multiple lamp boards 100 are disposed on the second circuit board 9, with a second seam gap D2 maintained between the lamp boards 100. At this time, the edge of the second circuit board 9 protrudes beyond the outermost edge of the lamp board 100. Thus, two second circuit boards 9 of different sizes, combined with the same number of lamp boards 100, result in two display panels 200 of different sizes, and the light-emitting elements 6 are uniformly distributed on both display panels 200.

[0076] The second circuit board 9 may be provided with a second marking structure 92 for indicating the position of each lamp panel 100. For example, the second marking structure 92 may be a frame-shaped indicator line corresponding to the edge contour of the lamp panel 100. Figure 6 and Figure 8 In the diagram, the box-shaped indicator line is shown as a dashed line. In many other embodiments, the second marker structure 92 may have other forms.

[0077] In one embodiment, the display panel 200 further includes a base plate (not shown), to which each lamp panel 100 is fixed to the surface of the base plate to maintain the corresponding seam gap. Here, the base plate may be one of the aforementioned retaining structures.

[0078] In some embodiments, the base plate and the second circuit board 9 may be at least partially integrated. For example, when the second circuit board 9 is a rigid circuit board, it can simultaneously serve to electrically connect each lamp board 100 and support each lamp board 100. In some embodiments, the base plate and the second circuit board 9 are two independent structures. The display panel 200 may simultaneously include the second circuit board 9 and the base plate disposed on the side of the second circuit board 9 away from the lamp board 100.

[0079] Please see Figure 9 As shown, this application embodiment also provides a method for manufacturing a display panel 200, which is assembled from the lamp panels 100 described in the above embodiments. Specifically, the manufacturing method includes:

[0080] A plurality of first circuit boards 5 are provided, each first circuit board 5 having a plurality of first mounting positions and a plurality of second mounting positions, wherein the distance between adjacent first mounting positions is a first distance d1 and the distance between adjacent second mounting positions is a second distance d2;

[0081] Provides multiple light-emitting elements 6;

[0082] Light-emitting elements 6 are respectively installed in the first mounting position and connected to the first circuit board 5 to obtain multiple light panels 100. The multiple light panels 100 are spliced ​​together according to the first splicing gap D1 to form a display panel 200. In each light panel 100, the distance between adjacent light-emitting elements 6 is the first distance d1, and the distance between adjacent light-emitting elements 6 on adjacent light panels 100 is also the first distance d1. Alternatively, light-emitting elements 6 are respectively installed in the second mounting position and connected to the first circuit board 5 to obtain multiple light panels 100. The multiple light panels 100 are spliced ​​together according to the second splicing gap D2 to form a display panel 200. In each light panel 100, the distance between adjacent light-emitting elements 6 is the second distance d2, and the distance between adjacent light-emitting elements 6 on adjacent light panels 100 is also the second distance d2.

[0083] The method for manufacturing the display panel 200 provided in this application embodiment uses multiple lamp boards 100 spliced ​​together, and each lamp board 100 has two sets of mounting positions at different distances. This allows the lamp boards 100 to be spliced ​​together with different splicing gaps, resulting in two sizes of display panels 200. The light-emitting elements 6 are evenly arranged on the entire display panel 200. Thus, when manufacturing display panels 200 of different sizes, it is not necessary to manufacture large-sized circuit boards individually; instead, only universal, small-sized lamp boards 100 need to be manufactured. The small-sized lamp boards 100 are relatively simple in wiring design and manufacturing. For example, the first circuit board 5 can be a single-layer circuit board. The connection wiring between the lamp boards 100 is not constrained by the first circuit board 5, and the design is relatively simplified. Overall, this reduces the design cost and manufacturing cost of the display panel 200, and also shortens the manufacturing cycle to a certain extent.

[0084] In one embodiment, see Figure 10 As shown, in this manufacturing method, splicing multiple light panels 100 together to form a display panel 200 according to a first splicing gap D1 includes: providing a second circuit board 9, splicing multiple light panels 100 together to the surface of the second circuit board 9 according to the first splicing gap D1, and electrically connecting each light panel 100 to the second circuit board 9. Splicing multiple light panels 100 together to form a display panel 200 according to a second splicing gap D2 includes: providing a second circuit board 9, splicing multiple light panels 100 together to the surface of the second circuit board 9 according to the second splicing gap D2, and electrically connecting each light panel 100 to the second circuit board 9.

[0085] The wiring between the multiple lamp boards 100 is achieved through an additional second circuit board 9. Since the wiring design has been simplified, the design and manufacturing of the second circuit board 9 can also be simplified accordingly. For example, the second circuit board 9 can also be a single-layer circuit board. In this case, the wiring connection between the lamp boards 100 can be completed by directly soldering each lamp board 100 to the second circuit board 9, which simplifies the assembly steps of the display panel 200.

[0086] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
