Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.

[0030] In addition, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features, so that the features with "first" and "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly and specifically limited.

[0031] Referring to Figure 1 The present embodiment provides a backlight module, which comprises a back plate 11 and a lamp strip 12 arranged on the back plate 11; a first reinforcing rib 111 is arranged on one side of the back plate 11 close to the lamp strip 12, and the first reinforcing rib 111 is in a bent or curved shape. The first reinforcing rib 111 of the back plate 11 is arranged in a bent or curved shape in the backlight module, so that the lamp strip 12 can avoid being located on the reinforcing rib as a whole or in most areas when the lamp strip 12 is laid, thereby facilitating the fixation of the lamp strip 12, making the back plate 11 and the lamp strip 12 compatible, and improving the reusability of the back plate 11.

[0032] Referring to Figure 2 In some embodiments, the back plate 11 has opposite inner and outer bottom surfaces 112 and 113, and part of the inner bottom surface 112 of the back plate 11 protrudes towards the outer bottom surface 113 to form the first reinforcing rib 111, and the first reinforcing rib 111 and the inner bottom surface 112 of the back plate 11 form the first groove 101, that is, the first reinforcing rib 111 in the present embodiment is a concave rib. If the concave rib is arranged in a bent or curved shape, most or all of the lamp strip 12 can be avoided from being located on the concave rib, thereby facilitating the fixation of the lamp strip 12, making the lamp strip 12 compatible with the back plate 11, and thereby improving the reusability of the back plate 11.

[0033] Referring to Figure 3In another embodiment, the back plate 11 has opposite inner bottom surface 112 and outer bottom surface 113, and part of the outer bottom surface 113 of the back plate 11 protrudes towards the inner bottom surface 112 to form the first reinforcing ribs 111, and the second grooves 102 are formed between adjacent first reinforcing ribs 111, that is, the first reinforcing ribs 111 in this embodiment are convex ribs. If the convex ribs are arranged in a bent or curved shape, so that the second grooves 102 are formed in a bent or curved shape, the lamp strip 12 cannot be fixed on the second grooves 102 in whole or in most part, so that the lamp strip 12 is compatible with the back plate 11, thereby improving the reusability of the back plate 11.

[0034] As an embodiment, when the convex ribs are arranged in the back plate 11, the first reinforcing ribs 111 form the third grooves 103 with the outer bottom surface 113 of the back plate 11, and the convex ribs are arranged to strengthen the back plate 11, so as to improve the reliability of the backlight module.

[0035] Please refer to Figure 4 and Figure 5 , the following embodiments are described with the back plate 11 arranged with concave ribs. In some embodiments, the lamp strip 12 includes a plurality of first sub-parts 121 and a plurality of second sub-parts 122 connected alternately, the first sub-parts 121 are located above the first grooves 101, and the second sub-parts 122 abut against the back plate 11. When the first reinforcing ribs 111 in the back plate 11 are arranged in a bent or curved shape, the lamp strip 12 has a plurality of first sub-parts 121 and a plurality of second sub-parts 122 on the back plate 11, wherein the first sub-parts 121 are suspended on the first grooves 101, and the second sub-parts 122 abut against the back plate 11. At this time, since the first sub-parts 121 and the second sub-parts 122 are arranged alternately, the first sub-parts 121 in the lamp strip 12 can be cooled by the part of the back plate 11 abutting against the second sub-parts 122, thereby improving the heat dissipation performance of the backlight module.

[0036] At the same time, since the first sub-parts 121 and the second sub-parts 122 in the lamp strip 12 are arranged alternately, the uniformity of the lamp strip 12 when fixed can be ensured, thereby improving the stability of the lamp strip 12 and ensuring the reliability of the backlight module.

[0037] In some embodiments, the extension direction of the first reinforcing ribs 111 is the same as the extension direction of the lamp strip 12, such as Figure 1 and Figure 4As shown, the extending direction of the light bar 12 is taken as the first direction, such as the X direction in the figure, and the direction perpendicular to the first direction is taken as the second direction, such as the Y direction in the figure. When the extending direction of the first reinforcing rib 111 is the same as the extending direction of the light bar 12, the first reinforcing rib 111 is arranged in a bent shape or a curved shape, which can avoid that the light bar 12 is located on the concave rib in most or all of the light bar 12, thereby facilitating the fixation of the light bar 12, making the light bar 12 compatible with the back plate 11, and thereby improving the reusability of the back plate 11. At the same time, the stability of the light bar 12 and the heat dissipation performance of the overall backlight module can also be improved.

[0038] Please refer to Figure 6 In other embodiments, the extending direction of the first reinforcing rib 111 intersects with the extending direction of the light bar 12, such as that the first reinforcing rib 111 is arranged along the X direction, and the extending direction of the first reinforcing rib 111 is inclined at a certain angle with respect to the X direction. A plurality of parallel first reinforcing ribs 111 are arranged, and in the same way, the light bar 12 as a whole or in most of the light bar 12 can be avoided to be located on the first reinforcing rib 111, thereby improving the reusability of the back plate 11.

[0039] Please refer to Figure 7 and Figure 8 In some embodiments, the side of the back plate 11 close to the light bar 12 is further provided with a second reinforcing rib 114, and the extending direction of the second reinforcing rib 114 intersects with the extending direction of the first reinforcing rib 111. In this embodiment, the second reinforcing rib 114 different from the first reinforcing rib 111 is additionally arranged, which can further improve the strength of the back plate 11.

[0040] As an embodiment, the extending direction of the second reinforcing rib 114 is perpendicular to the extending direction of the first reinforcing rib 111. When the first reinforcing rib 111 and the second reinforcing rib 114 are arranged perpendicularly, the ribs are formed in a crisscross manner on the back plate 11, which is conducive to improving the strength of the back plate 11, and thereby improving the reliability of the backlight module.

[0041] As an embodiment, the first reinforcing rib 111 and the second reinforcing rib 114 can be both convex ribs or both concave ribs. When the first reinforcing rib 111 and the second reinforcing rib 114 are both concave ribs, the first concave groove 101 formed by the first reinforcing rib 111 in the back plate 11 is communicated with the concave groove formed by the inner bottom surface 112 of the back plate 11. When the first reinforcing rib 111 and the second reinforcing rib 114 are both convex ribs, the third concave groove 103 formed by the first reinforcing rib 111 in the back plate 11 is communicated with the concave groove formed by the outer bottom surface 113 of the back plate 11 and the second reinforcing rib 114. The first reinforcing rib 111 and the second reinforcing rib 114 can be integrally stamped and formed.

[0042] As an embodiment, the first reinforcing rib 111 and the back plate 11 are integrally formed, such as that the first reinforcing rib 111 can be stamped and formed by the back plate 11.

[0043] The first reinforcing rib 111 can be curved, for example, in the shape of a wave in Figure 1 The first reinforcing rib 111 can be bent, for example, in the shape of a square wave in Figure 4 The first reinforcing rib 111 can be sawtooth-shaped, for example, in the shape of a sawtooth in Figure 8 The first reinforcing rib 111 can be zigzag-shaped, for example, in the shape of a zigzag in
