[0051] Example 1

[0052] This disclosure provides a backlight module, such as... Figures 1 to 3 As shown, the backlight module includes a backplate 100, a lamp board 200, and a plurality of first light-emitting elements 400. The lamp board 200 is disposed on the backplate 100 and includes a substrate 210 and a plurality of strip plates 220. The first ends of the plurality of strip plates 220 are connected to a connecting plate 340 to form a comb-like structure. The plurality of first light-emitting elements 400 are spaced apart along the extending direction of the strip plates 220. The second end of the strip plate 220 is provided with a connecting portion 222, and a connecting mating portion 120 is provided at a position on the backplate 100 corresponding to the second end of the strip plate 220. The connecting portion 222 and the connecting mating portion 120 are connected in a mating manner.

[0053] In this embodiment, multiple strip plates 220 and connecting plates 340 form a comb-like structure to reduce the area of ​​the lamp panel 200, thereby reducing the amount of substrate used to produce the lamp panel 200 and lowering the production cost of the lamp panel 200.

[0054] The first end of the strip plate 220 is connected to the connecting plate 340, and the second end of the strip plate 220 is the end of the strip plate 220. By providing a connecting part 222 at the second end of the strip plate 220 and a corresponding connecting mating part 120 on the back plate 100, the connecting part 222 and the connecting mating part 120 are connected to fix the end of the strip plate 220 to the back plate 100, reducing the risk of deformation of the strip plate 220 and warping of the end of the strip plate 220, improving the connection stability between the strip plate 220 and the back plate 100, thereby improving the overall structural stability and operational reliability of the backlight module, and improving the brightness and color uniformity of the display device when the backlight module is used in the display device, thus improving the user experience.

[0055] And, through the matching connection of the connecting part 222 and the connecting matching part 120, compared with the bonding connection mode in the prior art, the drying time of the bonding agent can be reduced, and the production efficiency of the backlight module can be improved.

[0056] Exemplarily, as shown in Figure 2 The second end of the strip-shaped plate 220 is provided with a clamping hole 223, and the back plate 100 is provided with a limiting flange 121. After the limiting flange 121 passes through the clamping hole 223, the limiting flange 121 is bent towards the strip-shaped plate 220 to be connected with the first plate surface 221. The connecting part 222 includes the clamping hole 223, and the connecting matching part 120 includes the limiting flange 121.

[0057] In this embodiment, the connecting part 222 includes the clamping hole 223, and the connecting matching part 120 includes the limiting flange 121. After the limiting flange 121 passes through the clamping hole 223, the limiting flange 121 is bent towards the strip-shaped plate 220, and the limiting flange 121 is connected with the first plate surface 221 of the strip-shaped plate 220. The limiting flange 121 can clamp the second end of the strip-shaped plate 220 to fix and limit the second end of the strip-shaped plate 220, reduce the deformation or edge lifting of the end of the strip-shaped plate 220, improve the connection stability of the strip-shaped plate 220 and the back plate 100, and thus improve the overall structural stability and working reliability of the backlight module.

[0058] Alternatively, the limiting flange 121 is bent and arranged before the strip-shaped plate 220 is connected with the back plate 100. When the strip-shaped plate 220 is connected with the back plate 100, the strip-shaped plate 220 can extend into a limiting space enclosed by the limiting flange 121 and the back plate 100 to limit the second end of the strip-shaped plate 220.

[0059] Alternatively, the limiting flange 121 extends away from the back plate 100 before the strip-shaped plate 220 is connected with the back plate 100. When the strip-shaped plate 220 is connected with the back plate 100, the limiting flange 121 is bent towards the strip-shaped plate 220 after passing through the clamping hole 223. The strip-shaped plate 220 is pressed between the limiting flange 121 and the back plate 100 to limit the second end of the strip-shaped plate 220.

[0060] Alternatively, the backlight module further includes a plurality of second light emitting elements 500, and the plurality of second light emitting elements 500 are arranged at intervals along the extension direction of the substrate 210.

[0061] In this embodiment, the plurality of second light emitting elements 500 are arranged at intervals along the extension direction of the substrate 210, and the extension direction of the substrate 210 is the interval arrangement direction of the plurality of strip-shaped plates 220. The second light emitting elements 500 are arranged on the substrate 210, which can fill the gap area of the light source distribution, improve the uniformity of the light source distribution, increase the light source distribution area, and improve the display effect of the display device.

[0062] Optionally, the substrate 210 is connected to the back plate 100 by bolts.

[0063] Embodiment two is different from embodiment one in that:

[0064] As shown in Figure 4 , optionally, the plurality of second light emitting elements 500 are arranged in a matrix on the substrate 210.

[0065] Embodiment three is different from embodiment one and embodiment two in that:

[0066] In some optional embodiments, as shown in Figures 5 to 7 , the second end of the strip-shaped plate 220 is provided with a first through hole 224, the back plate 100 is provided with a second through hole 130, and the backlight module further comprises a clamping piece 300. The clamping piece 300 passes through the first through hole 224 and the second through hole 130, and the first end of the clamping piece 300 is connected to the first plate surface 221 of the lamp plate 200 away from the back plate 100, and the second end of the clamping piece 300 is connected to the second plate surface 110 of the back plate 100 away from the lamp plate 200.

[0067] In this embodiment, the clamping piece 300 passes through the first through hole 224 and the second through hole 130, and the two ends of the clamping piece 300 are respectively connected to the first plate surface 221 of the lamp plate 200 and the second plate surface 110 of the back plate 100. The second end of the lamp plate 200 is connected to the back plate 100 through the clamping piece 300, which increases the connection stability of the lamp plate 200 and the back plate 100, and improves the working reliability and stability of the backlight module.

[0068] Optionally, as shown in Figures 6 to 8 , the clamping piece 300 comprises a first sheet body 310 and a second sheet body 320. The first end of the second sheet body 320 is connected to the first sheet body 310, and there is a first folding angle between the first sheet body 310 and the second sheet body 320.

[0069] Optionally, the first sheet body 310 is connected to the first plate surface 221, and the second end of the second sheet body 320 is bent after passing through the first through hole 224 and the second through hole 130 to be connected to the second plate surface 110.

[0070] Optionally, the first sheet body 310 is connected to the second plate surface 110, and the second end of the second sheet body 320 is bent after passing through the second through hole 130 and the first through hole 224 to be connected to the first plate surface 221.

[0071] Exemplarily, the side wall of the first sheet body 310 facing the second plate surface 110 is connected to the second plate surface 110, the extension direction of the plate surface 312 of the first sheet body intersects the extension direction of the second plate surface 110, and the plate surface of the second end of the second sheet body 320 is connected to the first plate surface 221.

[0072] In the embodiment, the extending direction of the plate surface 312 of the first sheet body intersects with the extending direction of the second plate surface 110, the side wall of the first sheet body 310 towards the second plate surface 110 can be clamped to the second plate surface 110, and the second end of the second sheet body 320 is bent after passing through the second through hole 130 and the first through hole 224, and the plate surface of the second end of the second sheet body 320 is connected with the first plate surface 221. In this way, the second end of the strip-shaped plate 220 is pressed between the side wall 311 of the first sheet body and the plate surface of the second sheet body 320, so as to reduce the deformation and warping of the second end of the strip-shaped plate 220, and improve the connection stability of the strip-shaped plate 220 and the back plate 100.

[0073] In addition, the plate surface of the second sheet body 320 is connected with the first plate surface 221, which can reduce the length of the second sheet body 320 protruding from the first plate surface 221, and reduce the case that the second sheet body 320 hinders the installation of the lamp plate 200.

[0074] Optionally, the second end of the second sheet body 320 is provided with a partition strip hole to separate the second end of the second sheet body 320 into a plurality of end plates, the bending directions of the plurality of end plates are different, so as to limit the strip-shaped plate 220 in a plurality of directions of the first through hole 224, and reduce the deformation and warping of the second end of the strip-shaped plate 220.

[0075] In the fourth embodiment, the difference from the third embodiment is that:

[0076] In some optional embodiments, as shown in Figures 9 to 11 The clamping piece 300 includes a fixed plate 330, a connecting plate 340 and a clamping plate 350. The plate surface of the fixed plate 330 is connected with the first plate surface 221. The first end of the connecting plate 340 is connected with the fixed plate 330, and there is a second bending angle between the connecting plate 340 and the fixed plate 330. The connecting plate 340 is located in the first through hole 224 and the second through hole 130. The first end of the clamping plate 350 is fixedly connected with the second end of the connecting plate 340, and there is a third bending angle between the clamping plate 350 and the connecting plate 340. The plate surface of the clamping plate 350 is connected with the second plate surface 110.

[0077] In the embodiment, the connecting plate 340 is bently connected with the fixed plate 330, and the connecting plate 340 is bently connected with the clamping plate 350. The connecting plate 340 is located in the first through hole 224 and the second through hole 130, so that the plate surface of the fixed plate 330 and the plate surface of the clamping plate 350 can be correspondingly connected with the first plate surface 221 and the second plate surface 110 respectively, thereby connecting the second end of the strip-shaped plate 220 with the back plate 100, and reducing the deformation and warping of the second end of the strip-shaped plate 220.

[0078] Optionally, the fixing plate 330 is fixedly connected with the first plate surface 221, so as to fix the clamping piece 300 on the strip plate 220. When installing the lamp plate 200, the lamp plate 200 can be first set in an inclined manner, so that the clamping plate 350 passes through the second through hole 130, and the connecting plate 340 is located in the second through hole 130. Then, the lamp plate 200 is attached to the back plate 100, and the plate surface of the clamping plate 350 can also be attached to the second plate surface 110, so as to reduce the installation operation steps and the installation difficulty.

[0079] Optionally, as shown in Figure 10 and Figure 11 The clamping piece 300 further comprises a guide plate 351, the first end of the guide plate 351 is connected with the second end of the clamping plate 350, and the second end of the guide plate 351 extends away from the plane where the fixing plate 330 is located in the direction along the first end of the clamping plate 350 towards the second end of the clamping plate 350.

[0080] In the embodiment, the second end of the guide plate 351 extends away from the plane where the fixing plate 330 is located in the direction along the second end of the clamping plate 350 towards the first end of the clamping plate 350, and the distance between the guide plate 351 and the strip plate 220 gradually decreases. In this way, when installing the lamp plate 200, the guide plate 351 can guide the running direction of the clamping plate 350, so as to facilitate the clamping plate 350 to pass through the second through hole 130 and be connected with the back plate 100, and reduce the installation difficulty of the lamp plate 200.

[0081] The fifth embodiment is different from the fourth embodiment in that:

[0082] In some optional embodiments, as shown in Figure 12 and Figure 13 The back plate 100 is provided with a third through hole 140, the third through hole 140 is arranged in a spaced manner with the second through hole 130, and the clamping piece 300 further comprises a bent plate 352, the first end of the bent plate 352 is connected with the second end of the clamping plate 350, and part of the bent plate 352 is bent towards the fixing plate 330, or all of the bent plate 352 is bent towards the fixing plate 330, and the bent plate 352 is located in the third through hole 140.

[0083] In this embodiment, the bending plate 352 is connected to the second end of the snap-fit ​​plate 350, and the bending plate 352 is bent towards the fixing plate 330, located inside the third through hole 140. The third through hole 140 is spaced apart from the second through hole 130. That is, the snap-fit ​​plate 350 is connected to the second plate surface 110 of the back plate 100 between the third through hole 140 and the second through hole 130, and the two ends of the back plate 100 between the second through hole 130 and the third through hole 140 are the connecting plate 340 and the bending plate 352, respectively. This can reduce the occurrence of the snap-fit ​​component 300 coming out of the second through hole 130 during the use or transportation of the backlight module, improve the connection stability between the snap-fit ​​component 300 and the back plate 100, and thus improve the connection stability and reliability between the lamp board 200 and the back plate 100.

[0084] Example 6 differs from Example 3 in that:

[0085] In some alternative embodiments, such as Figures 14 to 16 As shown, the snap-fit ​​component 300 includes a pressing plate 360, a connecting piece 370, and an elastic arm 380. The surface of the pressing plate 360 ​​is connected to the first plate surface 221. The first end of the connecting piece 370 is connected to the pressing plate 360, and the second end of the connecting piece 370 passes through the first through hole 224 and the second through hole 130.
