[0039] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, the backlight module involved in the embodiment of this application includes: a plurality of light-emitting components 100 and a plurality of connection components 200.

[0040] Specifically, the plurality of light-emitting components 100 are arranged at intervals in the first direction, and the plurality of light-emitting components 100 are arranged in the second direction. Each light-emitting component 100 has an electrically connecting surface 110 in the first direction; any two adjacent light-emitting components 100 are electrically connected through the connection component 200. Each connection component 200 includes a first connecting member 210 and a second connecting member 220 electrically connected to the first connecting member 210. Among any two adjacent light-emitting components 100, the first connecting member 210 is connected to the electrically connecting surface 110 of one of the light-emitting components 100, and the second connecting member 220 is connected to the electrically connecting surface 110 of the other light-emitting component 100; wherein, the first direction and the second direction are perpendicular to each other. In the first direction, the distance between the electrically connecting surfaces 110 of any two adjacent light-emitting components 100 is L1, the distance from the connection point of the first connecting member 210 and the second connecting member 220 to one of the light-emitting components 100 is L2, and the distance from the connection point of the first connecting member 210 and the second connecting member 220 to the other light-emitting component 100 is L3, satisfying: L3 = L1 + L2.

[0041] It should be noted that the first direction is the direction indicated by x in Figure 1 and the second direction is the direction indicated by y in Figure 1 ​

[0042] Specifically, in the above embodiments, the light-emitting member 100 is a lamp board or a lamp strip.

[0043] In the above backlight module, there are a plurality of light-emitting members 100 arranged at intervals in the first direction to meet the requirement that the light-emitting members 100 of the backlight module are not on the same horizontal plane. At the same time, any two adjacent light-emitting members 100 can be electrically connected through the connection assembly 200. Among any two adjacent light-emitting members 100, due to the distance L1 between the electrical connection surfaces 110 of the two light-emitting members 100 in the first direction, the distance L2 from the connection point of the first connecting member 210 and the second connecting member 220 to one of the light-emitting members 100 in the first direction, and the distance L3 from the connection point of the first connecting member 210 and the second connecting member 220 to the other light-emitting member 100 in the first direction, the following is satisfied: L3 = L1 + L2. In this way, when any two adjacent light-emitting members 100 are electrically connected, the two adjacent light-emitting members 100 can be kept in a state of being arranged at intervals in the first direction, so that any two adjacent light-emitting members 100 can be spliced on different horizontal planes.

[0044] Refer to Figure 4 As shown, each second connecting member 220 has a first connecting portion 221 and a second connecting portion 222 electrically connected to the first connecting portion 221. The first connecting portion 221 is connected to the electrical connection surface 110, and the second connecting portion 222 is connected to one end of the first connecting portion 221 away from the electrical connection surface 110 in the first direction, and the end of the second connecting portion 222 away from the first connecting portion 221 is electrically connected to the first connecting member 210.

[0045] It can be understood that the end of the second connecting portion 222 away from the first connecting portion 221 can be electrically connected to the first connection to achieve the electrical connection between the first connecting member 210 and the second connecting member 220. In this process, the first connecting portion 221 is used to be electrically connected to the light-emitting member 100, and the second connecting portion 222 can compensate for the distance difference between any two adjacent light-emitting members 100 in the first direction, so that the first connecting member 210 and the second connecting member 220 can be electrically connected without changing the distance between the two light-emitting members 100, so that any two adjacent light-emitting members 100 can be spliced on different horizontal planes.

[0046] Refer to Figure 5 As shown, the first connecting member 210 is provided with a connection hole 211, and the end of the second connecting portion 222 away from the first connecting portion 221 passes through the connection hole 211.

[0047] It can be understood that since one end of the second connecting portion 222 away from the first connecting portion 221 penetrates through the first connecting member 210, in this way, the second connecting portion 222 can be electrically connected to the first connecting member 210, thereby realizing the electrical connection between the first connecting member 210 and the second connecting member 220, and further realizing the electrical connection between any two adjacent light-emitting members 100.

[0048] Specifically, in the first direction, the length of the second connecting portion 222 is L4, and the distance between the end of the second connecting portion 222 connected to the first connecting portion 221 and the connecting hole 211 is L5, satisfying: L4≥L5.

[0049] It can be understood that in the first direction, if L4<L5, without changing the distance between the two light-emitting members 100, the second connecting portion 222 will not be able to penetrate through the connecting hole 211, that is, the second connecting portion 222 will not be able to be electrically connected to the first connecting member 210. When L4≥L5, the second connecting portion 222 can make up for the distance difference between the first connecting portion 221 and the connecting hole 211, so that the second connecting portion 222 can penetrate through the connecting hole 211, thereby realizing the electrical connection between the second connecting portion 222 and the first connecting member 210, and further realizing the electrical connection between two adjacent light-emitting members 100, and ensuring that the distance between the two light-emitting members 100 does not change, so as to realize the splicing of any two adjacent light-emitting members 100 on different horizontal planes.

[0050] Refer to Figure 4 As shown, the second connecting portion 222 has bendability, so as to divide the second connecting portion 222 into a first connecting section 2221 extending along the first direction and a second connecting section 2222 extending along the second direction. One end of the first connecting section 2221 away from the second connecting section 2222 is connected to the first connecting portion 221, and one end of the second connecting section 2222 away from the first connecting section 2221 penetrates through the connecting hole 211.

[0051] Specifically, in the above embodiment, the connecting hole 211 extends along the second direction.

[0052] It can be understood that any two adjacent light-emitting elements 100 are not only spaced apart in the first direction, but also arranged in the second direction. Since the second connecting portion 222 has bendability, thus, the second connecting portion 222 can be bent to divide the second connecting portion 222 into a first connecting segment 2221 extending in the first direction and a second connecting segment 2222 extending in the second direction, so as to make up for the distance difference in the first direction between the first connecting portion 221 and the connecting hole 211 through the first connecting segment 2221 extending in the first direction, and enable the second connecting portion 222 to pass through the connecting hole 211 through the second connecting segment 2222 extending in the second direction, thereby realizing the electrical connection between the second connecting portion 222 and the first connecting member 210, and further realizing the electrical connection between the second connecting member 220 and the first connecting member 210, so as to realize the electrical connection between two adjacent light-emitting elements 100, and ensure that the distance between the two light-emitting elements 100 does not change, so as to realize the splicing of any two adjacent light-emitting elements 100 on different horizontal planes.

[0053] Referring to Figure 5 As shown, the bending point of the second connecting portion 222 and the central axis of the connecting hole 211 are located in the same plane perpendicular to the first direction.

[0054] It can be understood that since the bending point of the second connecting portion 222 and the central axis of the connecting hole 211 are located in the same plane perpendicular to the first direction, thus, the second connecting segment 2222 can pass through the connecting hole 211 along the second direction, and the distance between the two light-emitting elements 100 will not change.

[0055] Continuing to refer to Figure 5 As shown, in the first direction, the length of the first connecting segment 2221 is L6, satisfying: 1mm ≤ L6 ≤ 10mm.

[0056] Specifically, in the above embodiment, L6 can take values such as 1mm, 4mm, 6mm, 8mm, 10mm, etc., and the specific value is determined according to the distance between two adjacent light-emitting elements 100 in the first direction.

[0057] It can be understood that in the first direction, when L6 < 1 mm, the first connecting section 2221 will be too short, that is, the distance between the bending point and the end of the second connecting portion 222 close to the first connecting portion 221 will be too small. Thus, the first connecting section 2221 will not be able to compensate for the distance difference between the first connecting portion 221 and the connecting hole 211 in the first direction. When electrically connecting the first connector 210 and the second connector 220, it will not be possible to ensure that the distance between the two light-emitting elements 100 does not change, and thus it will not be possible to achieve the splicing of any two adjacent light-emitting elements 100 on different horizontal planes. When L6 > 10 mm, the first connecting section 2221 will be too long, that is, the distance between the bending point and the end of the second connecting portion 222 close to the first connecting portion 221 will be too large. Thus, the length of the first connecting section 2221 will be greater than the distance between the connecting hole 211 and the first connecting portion 221. When electrically connecting the first connector 210 and the second connector 220, the first connecting section 2221 will have a redundant length, which not only affects the aesthetics of the assembly but also increases the connection difficulty. When the length L6 of the first connecting section 2221 satisfies 1 mm ≤ L6 ≤ 10 mm, it can not only ensure that the distance between the two light-emitting elements 100 does not change and achieve the splicing of any two adjacent light-emitting elements 100 on different horizontal planes, but also reduce the connection difficulty.

[0058] Referring to Figures 6 to 8 As shown, at both ends of any one light-emitting element 100 in the second direction, a first connector 210 is connected;

[0059] Or at both ends of any one light-emitting element 100 in the second direction, a second connector 220 is connected;

[0060] Or at both ends of any one light-emitting element 100 in the second direction, a first connector 210 and a second connector 220 are respectively connected.

[0061] It can be understood that among any three adjacent light-emitting elements 100, in the second direction, referring to Figure 6 As shown, if the middle light-emitting element 100 is lower than the two light-emitting elements 100 at its two ends in the first direction, then a second connector 220 can be connected to both ends of the middle light-emitting element 100 in the second direction, and a first connector 210 can be connected to the ends of the two edge light-emitting elements 100 close to the middle light-emitting element 100, so as to achieve the splicing of three adjacent light-emitting elements 100 on different horizontal planes. Referring to Figure 7As shown, if the middle light-emitting component 100 is higher than the two light-emitting components 100 at its two ends in the first direction, a first connecting component 210 can be connected to both ends of the middle light-emitting component 100 along the second direction, and a second connecting component 220 can be connected to one end of each of the two edge light-emitting components 100 close to the middle light-emitting component 100, so as to realize the splicing of three adjacent light-emitting components 100 on different horizontal planes. Refer to Figure 8 As shown, if the three light-emitting components 100 are successively decreased or increased step by step in the first direction, a first connecting component 210 and a second connecting component 220 can be respectively arranged at both ends of the middle light-emitting component 100 along the second direction. Among the two edge light-emitting components 100, a second connecting component 220 is connected to one end of one light-emitting component 100 close to the middle light-emitting component 100, and a first connecting component 210 is connected to one end of the other light-emitting component 100 close to the middle light-emitting component 100, so as to realize the splicing of three adjacent light-emitting components 100 on different horizontal planes.

[0062] Specifically, the first connecting component 210 is a female header, and the second connecting component 220 is a male pin, and the male pin is inserted into the female header.

[0063] It can be understood that the electrical connection between any two adjacent light-emitting components 100 can be realized by the insertion of the male pin into the female header. At the same time, the height difference between the two light-emitting components 100 in the first direction can be compensated by changing the height of the male pin in the first direction, so as to ensure that the distance between the two light-emitting components 100 does not change, and the splicing of any two adjacent light-emitting components 100 on different horizontal planes is realized.

[0064] The display device involved in the embodiment of the present application includes: the above-mentioned backlight module.

[0065] In the above-mentioned display device, since the above-mentioned backlight module can realize the splicing of the light-emitting components 100 on different horizontal planes, therefore, the backplane of the above-mentioned display device can be designed with more diversity, so as to improve the aesthetics of the above-mentioned display device.
