Optionally, the bending portion 122 is perpendicular to the sidewall 12a, and the bending portion 122 bends toward the inner side of the accommodating space.
Of course, the manner of hinging the side wall and the supporting wall is not limited to the above two manners, and the embodiment of the present application does not limit this.
In each of the above embodiments, the area where the flexible circuit board 40 overlaps the light guide plate 22 may be made wider by disposing the flexible circuit board 40 between the light source and the bottom wall 11 of the back frame 10, so that the width of the non-display area of the backlight assembly may be reduced. Further, since the flexible circuit board 40 is disposed on the bottom wall 11, a rubber frame for supporting the flexible circuit board 40 can be omitted, and the width of the non-display area of the backlight module can be further shortened. On this basis, the display panel is further supported by the support wall 50 or 50a in the first state. Because the supporting wall 50 can be turned to the second state, the opening of the accommodating space can become larger, which is convenient for not affecting the normal assembly of the backlight module.
In other embodiments, a support may be further provided to improve the reliability of the support. See in particular the description below.

Alternatively, the support 51 is disposed on the light source 30 and on the area of the light guide plate 22 not covered by the light uniformizing element 23.
The support 51 and the end of the dodging element 23 close to each other have a clearance a between them, which on the one hand serves to match assembly errors; on the other hand, under the condition of certain cold and hot deformation, the backlight module can still work normally, and interference among parts can not occur.
Alternatively, the supporting member 51 may be made of a light shielding material at least at a portion located on the light guide plate 22 to prevent light emitted from the light source 30 from directly leaking out of the backlight module.
It should be understood that in other embodiments, the support 51 may be disposed only on the light source 30 or only on the area of the light guide plate 22 not covered by the light unifying element 23.
Alternatively, the support member 51 has elasticity and viscosity, and for example, the support member 51 may be foam rubber. Since the supporting member 51 has elasticity, it can have a certain buffering effect on the display panel when supporting the display panel. Since the support member 51 has adhesiveness, the support wall 50 is bonded to the support member 51 in the first state.
Referring to fig. 5, fig. 5 is a schematic partial perspective view of a back frame and a flexible circuit board according to an embodiment of the present application. In the above embodiments, the opening 123 is provided at least on the side wall 12 of the back frame 10. The flexible circuit board 40 extends out of the back frame 10 through the opening 123.
