The vertical distance from the end of the side wall 12 remote from the bottom wall 11 to the first bottom wall portion 111 is greater than the vertical distance from the end of the side wall 12 remote from the bottom wall 11 to the second bottom wall portion 112. In other words, the bottom wall 11 forms a recessed space surrounded by the side wall 12, the connecting portion 113, and the first bottom wall 111 at the first bottom wall 111. The concave space is a part of the accommodating space.
The optical assembly 20 is located in the accommodating space defined by the bottom wall 11 and the side wall 12, and the optical assembly 20 may include a reflective sheet 21, a light guide plate 22, and a light uniformizing element 23.
The flexible circuit board 40 is disposed on an area of the bottom wall 11 not covered by the optical assembly 20 and at least partially overlaps the optical assembly 20 in a width direction (a lateral direction in the drawing) of the backlight module. Alternatively, the flexible circuit board 40 is bonded to the first bottom wall portion 111 by the first bonding member 60. The first adhesive member 60 may be a double-sided tape. In other embodiments, the first adhesive member 60 may be other adhesives, such as a glue layer. The flexible circuit board 40 is at least partially accommodated in the concave space.
The reflection sheet 21 is provided on the second bottom wall portion 112.
The light guide plate 22 is partially disposed on the reflective sheet 21, and a portion of the light guide plate 22 not disposed on the reflective sheet 21 is bonded to a partial area of the surface of the flexible circuit board 40 away from the bottom wall 11 by the second adhesive member 70. The light guide plate 22 and the flexible circuit board 40 at least partially overlap in a width direction of the backlight assembly.
The light source 30 is disposed on a side of the flexible circuit board 40 remote from the bottom wall 11. The light source 30 is opposite to the side of the optical assembly 20 facing the sidewall 11. The light source 30 is located at a side of the optical assembly 20. Optionally, the light source 30 is located at a side of the light guide plate 22, for example, the light source 30 is located at the light incident side of the light guide plate 22. The light source 30 is disposed on a region of the flexible circuit board 40 not covered by the light guide plate 22, and the light source 30 is electrically connected to the flexible circuit board 40. The light source 30 is connected to the power supply circuit through a line on the flexible circuit board 40 so that the power supply circuit can supply power to the light source 30.
The light uniformizing element 23 is disposed on a partial region of the light guide plate 22. The reflective sheet 21, the light guide plate 22, and the light uniformizing element 23 are sequentially disposed in a direction away from the bottom wall 11. For example, as shown in the figure, the reflective sheet 21, the light guide plate 22, and the light uniformizing element 23 are stacked in this order from bottom to top.
Optionally, the surface of the light source 30 away from the bottom wall 11 is flush with the surface of the light guide plate 22 away from the bottom wall 11.

Optionally, the height of the support 50 above the surface of the light guide plate 22 away from the bottom wall 11 is greater than the height of the light uniformizing element 23 above the surface of the light guide plate 22 away from the bottom wall 11, and the height of the side wall 12 above the surface of the light guide plate 22 away from the bottom wall 11 is greater than or equal to the height of the support 50 above the surface of the light guide plate 22 away from the bottom wall 12. As shown, the height of the support member 50 above the upper surface of the light guide plate 22 is greater than the height of the light unifying element 23 above the upper surface of the light guide plate 22. When the display panel is supported on the support member 50, the support member 50 is compressed due to the elasticity of the support member 50, and the height of the support member 50 beyond the upper surface of the light guide plate 22 after being compressed is substantially flush with the height of the light uniformizing element 23 beyond the upper surface of the light guide plate 22, so as to form a stable support for the display panel.
The support 50 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 50 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.
In the present embodiment, the area where the flexible circuit board 40 overlaps the light guide plate 22 can 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 can 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 the basis, the support 50 is further arranged on the light source 30, the optical assembly 20 and the light source 30, so that the display panel can be stably supported. Further, the bottom wall 11 is recessed at the first bottom wall portion 111, reducing the thickness of the backlight module.
