The bottom plate 11 and the side plates 12 of the back plate 10 are integrally designed, and the surface shape of the bottom plate 11 includes a square shape, for example, a rectangular shape, and of course, the surface shape of the bottom plate 11 is not limited thereto. In this embodiment, the surface shape of the bottom plate 11 is illustrated as a square, and the side plate 12 includes four end-to-end side walls. The side plate 12 surrounds the bottom plate 11 to form a receiving cavity 111, and the receiving space is used for receiving other components of the backlight module 100, such as optical films including a light source, a reflective sheet, a light guide plate, a diffusion sheet, and a brightness enhancement film. Alternatively, the light source of the backlight module 100 may be a direct type or a side-in type.
The support member 20 is disposed on a side of the side plate 12 facing away from the accommodating chamber 111, and is detachably connected to the side plate 12. Alternatively, the support member 20 may be in a block shape, and the material of the support member 20 may be the same as that of the back plate 10, for example, all of which are sheet metal. The side of the support member 20 near the side plate 12 is provided with a first protruding portion 21, the side of the side plate 12 facing the support member 20 is provided with a first mounting hole 121, and the first protruding portion 21 is mountable in the first mounting hole 121, so that the support member 20 and the side plate 12 are detachably connected.
In one embodiment, the outer surface of the first protruding portion 21 and the inner surface of the first mounting hole 121 are both provided with threads, so that a threaded connection is formed between the first protruding portion 21 and the side plate 12.

When the first protruding portion 21 is cylindrical, the thickness of the first protruding portion 21 is the diameter of the cylinder.
Alternatively, when the first protrusion 21 is completely installed in the first installation hole 121, the support member 20 abuts against the side plate 12 provided with the first installation hole 121 without a gap therebetween, and at this time, the thickness of the first protrusion 21 is greater than the thickness of the support member 20 in a direction perpendicular to the plane of the bottom plate 11, so that the contact area between the first protrusion 21 and the side plate 12 can be increased, thereby enhancing the stability of the connection of the support member 20 and the back plate 10.
In one embodiment, as shown in fig. 5, a second protruding portion 122 is disposed on a side of the side plate 12 facing away from the supporting member 20, the second protruding portion 122 is disposed corresponding to the first mounting hole 121, and the first mounting hole 121 extends into the second protruding portion 122. The length L1 of the first protruding portion 21 is greater than the thickness D1 of the side plate 12 in the extending direction along the first mounting hole 121, so as to increase the fitting length of the first protruding portion 21 and the first mounting hole 121, thereby enhancing the locking force of the first protruding portion 21 and the first mounting hole 121, and further enhancing the stability of the connection of the support member 20 and the back plate 10. Of course, the extension length of the first mounting hole 121 is not limited to that shown in fig. 5, and the first mounting hole 121 of the present application may also extend through the second protrusion 122, so as to further increase the mating length of the first protrusion 21 and the first mounting hole 121.

In another embodiment, as shown in fig. 6, the detachable connection of the support member 20 and the printed circuit board 30 may be further achieved by: sliding grooves 201 are formed on opposite sides of the two support members 20, and opposite ends of the printed circuit board 30 are slid into the support members 20 from the corresponding sliding grooves 201, respectively, so that the support members 20 support and fix the printed circuit board 30. In this way, the printed circuit board 30 and the supporting member 20 are located on the same plane, which can save space and reduce the overall thickness of the backlight module 100.
In the backlight module 100 of the above embodiments, the supporting member 20 is detachably connected to the back plate 10 and is also detachably connected to the printed circuit board 30, so that when the fixing mode of the printed circuit board 30 needs to be switched from the lay-down mode to the bending mode, the printed circuit board 30 can be detached from the supporting member 20 and the supporting member 20 is detached from the back plate 10, and then the printed circuit board 30 is bent to the side of the back plate 10 away from the accommodating cavity 111 and is fixed to the back plate 10 by fixing modes such as double-sided adhesive, so as to realize the bending fixing mode of the printed circuit board 30, as shown in fig. 7. It will be appreciated that, as shown in fig. 7, the printed circuit board 30 is bent to a side of the back plate 10 away from the accommodating cavity 111, which means that a flexible circuit board (Flexible Print Circuit, FPC) 40 connected to the printed circuit board 30 is bent, and the printed circuit board 30 herein refers to a printed circuit board assembly (Printed Circuit Board Assembly, PCBA) with electronic components.
When the fixing mode of the printed circuit board 30 is to be changed from the bending mode to the lying mode, the printed circuit board 30 may be detached from the back plate 10, and the support member 20 may be attached to the back plate 10, so that the support member 20 is fixed to the back plate 10. The printed circuit board 30 is then mounted over the support member 20 such that the support member 20 supports and secures the printed circuit board 30 to achieve a flat-lying type securing of the printed circuit board 30, as shown in fig. 1. Therefore, for the display products of the same model, when the fixing mode of the printed circuit board 30 is switched, the back board 10 is not changed, and the back board 10 can share the same set of die, so that the back board die does not need to be opened again, and the cost is saved.
