[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes a backlight shell, please refer to Figure 1 and Figure 2 , including: a main board 10 and four baffles 11. The four baffles 11 are enclosed at the edges of the main board 10 to form a receiving cavity, which is used to accommodate components such as a light source and a light guide plate. The main board 10 extends at least one positioning member 12 along the length direction or the width direction, and a positioning hole 13 is provided in the positioning member 12. The positioning hole 13 is used to limit the backlight shell to facilitate accurate assembly on the backlight shell. Therefore, when the staff limits the backlight shell with the studs on the positioning holes 13, and the staff needs to spirally rotate the studs to connect them during the process of positioning the studs on the positioning holes 13, when the torque is uneven during the process, the positioning member 12 can absorb the torque well, protect the main board 10 from deformation, and enable the backlight shell and the backlight to achieve a better connection. Preferably, the main board 10 is a rectangular structure.

[0024] It should be noted that the number of the positioning members 12 is set by the size of the backlight shell. The larger the size of the backlight shell, the more positioning members 12 are required.

[0025] In one embodiment, see Figure 1 , the number of the positioning members 12 is four. The four positioning members 12 are evenly divided into two groups, and the two groups of positioning members 12 are respectively arranged on opposite sides of the main board 10. The positioning members 12 are positioned on both sides of the main board 10, so that the main board 10 no longer shakes during operation, and the limiting stability of the main board 10 is ensured.

[0026] Furthermore, the thickness of the positioning member 12 is greater than that of the main board 10, and thus the positioning member 12 is stronger than the main board 10, so the positioning member 12 can absorb greater torsion without deformation. The thickness of the main board 10 is 0.3 mm to 0.5 mm, and the thickness of the positioning member 12 is 0.8 mm to 1.2 mm.

[0027] Furthermore, the thickness of the positioning member 12 is 1.0 mm.

[0028] In another embodiment, see Figure 1 The positioning member 12 extends out of the reinforcement member 14, which is connected to the main board 10, so that the positioning member 12 can be more firmly connected to the main board 10, and prevent the positioning member 12 from deforming at the connection with the main board 10 due to excessive torque when the stud is installed. For further information, please refer to Figure 2 Each baffle 11 is provided with a female buckle 15 on its outer side, and the entire housing is provided with a male buckle on one side that is engaged with the baffle 11, so that the backlight housing can be quickly assembled to the entire housing. In addition, three female buckles 15 are provided on each baffle 11, which can strengthen the connection between the backlight housing and the entire housing.

[0029] In addition, the main board 10 and the baffle 11 are made of iron, which can better protect the components in the backlight housing.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
