The frame 10 and the side frame 20 are of an integral structure. The side frame 20 includes a plurality of side frame bars 21.
It should be noted that fig. 1a only schematically illustrates the back panel 2, in an actual product, the back panel 2 includes a bottom panel and side panels, the bottom panel is a main bearing structure of the display device, and the side panels are located around the bottom panel to form an accommodating cavity for accommodating components such as the light bar and the optical film. At this time, the frame 10 is parallel to the backboard 2, which means that the frame 10 is parallel to the bottom board in the backboard 2. Furthermore, it will be appreciated by those skilled in the art that the parallelism is not absolutely parallel, which allows for a range of errors.
The frame 10 includes a hollow area, and the hollow area may be rectangular, square, irregular, and the like, and may be specifically configured as required, which is not limited in the present invention.
It can be understood that the larger the hollow area is, the narrower the corresponding bezel 10 is, thereby realizing an ultra-narrow structure of the backlight module 1.
As shown in fig. 1a and 2a, the frame 10 is rectangular, and the hollow area is also rectangular. The side frame 20 disposed on the side of the frame 10 close to the back panel 2 and surrounding the side surface N of the back panel 2 comprises 4 side frame strips 21 (a shown in fig. 1a and 2a1、a2、b1、b2) The 4 side frame strips 21 form a rectangular frame.

Illustratively, as shown in FIGS. 1a and 2a, side frame strips a2A first notch 22 is provided near one side of the frame 10, and a first edge 221 (indicated by c in fig. 1a and 2 a) of the first notch 22, the frame 10 and the side frame strip a2Connected side L12And (4) overlapping.
A support sheet 30 is further disposed at a position corresponding to each first notch 22 on a side of the frame 10 away from the back plate 2, and one side of the support sheet 30 is connected to the first side 221 of the first notch 22 and is of an integral structure.
For example, as shown in fig. 1a and fig. 2a, on a side of the frame 10 away from the back panel 2, a side frame bar a is corresponding to the side frame bar2 A support plate 30 is disposed at the position of the first notch 22, one side of the support plate 30 is connected to a first side 221 (e.g., the side indicated by c in fig. 1a and 2 a) of the first notch 22, and the support plate 30 and the frame 10 are integrated.
It should be noted that, when the backlight module 1 is subsequently used in a display device, the display panel is located at one side of the frame 10 away from the back plate 2, the supporting sheet 30 surrounds the display panel, and here, the supporting sheet 30 is used for limiting the display panel and fixing the display panel; the support sheet 30 also serves to support the upper frame, which serves to protect the display panel.
The support sheet 30 is provided with a groove 31 on a side away from the frame 10.
In general, the material at the first notch 22 is cut (for example, by laser cutting), and then bent and extended in the thickness direction of the bezel 10 from the first edge 221 to form the corresponding support piece 30.
At this time, if the size of the first notch 22 is the same as the size of the supporting sheet 30, the used bending mold cannot generate an acting force, and the raw material at the first notch 22 cannot be bent from the first edge 221 to the thickness direction of the frame 10 under the condition of keeping the raw material at the first notch 22 flat, so in the prior art, the size of the first notch 22 is usually larger than that of the supporting sheet 30 to bend, and it is ensured that the size of the supporting sheet 30 correspondingly formed after the raw material at the first notch 22 is bent reaches a preset requirement, thereby, in the design, the height of the first notch 22 needs to be larger than that of the supporting sheet 30 along the thickness direction of the frame 10.
However, in order to realize the ultra-thin structure of the backlight module 1, the height of the side frame strip 21 along the X direction needs to be reduced as much as possible, and the minimum distance between the edge of the first notch 22 far from the side of the frame 10 and the edge of the side frame strip 21 far from the side of the frame 10 is at least 1mm, so as to ensure the strength and stability of the side frame strip 1, and therefore, the height of the first notch 22 along the X direction can only be reduced as much as possible.
Therefore, in the invention, the groove 31 is arranged on one side of the supporting sheet 30 away from the frame 10, the corresponding protrusion is arranged on the corresponding bending die, and in the preparation process, the protrusion on the die can be embedded into the groove 31, and bending is performed by the acting force generated by the groove 31, so that the height of the first notch 22 along the X direction is reduced, the height of the backlight module 1 along the X direction is further reduced, and the ultrathin structure of the backlight module 1 is realized.
It can be understood that, if the first notch 22 is disposed on the frame 10, the first edge 221 of the first notch 22 coincides with the edge where the frame 10 is connected to the side frame strip 21, the support sheet 30 is disposed at the position corresponding to the first notch 22, and one edge of the support sheet 30 is connected to the first edge 221 of the first notch 22, at this time, the height of the side frame 20 along the X direction may satisfy the ultra-thin requirement of the backlight module 1, but if the requirement of the height of the support sheet 30 along the X direction is also satisfied, the frame 10 may not satisfy the ultra-narrow requirement. In contrast to this, the present invention provides the first notch 22 on the side frame 20, which can realize both an ultra-narrow structure and an ultra-thin structure.

Based on this, since the supporting sheet 30 is provided with the groove 31 at a side away from the frame 10, the bending process is facilitated, and therefore, the supporting sheet 30 has a height corresponding to the first notch 22 (as shown by h in fig. 1b and 2 b-2 e)1) Height from the support sheet 30 (h as shown in fig. 1b and fig. 2 b-2 e)2) Equal, i.e. only 1.8 mm. The overall height of the corresponding middle frame 1 is only 4.6mm, which is reduced compared with the overall height of the middle frame 1 in the prior art.
Alternatively, as shown in fig. 1a to 2e, the groove 31 is located in the middle of the side of the support sheet 30 away from the frame 10.
