Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0033] In the description of the present application, the reference to "one embodiment", "some embodiments" or "embodiments" means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in other some embodiments" and the like appearing in the description are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. In addition, in one or more embodiments, specific features, structures or characteristics can be combined in any suitable manner.

[0034] The functional elements such as the connecting bracket, system board, circuit board, and speaker assembly in the display device are located on the back side of the display device. Since the functional elements have a certain thickness, after the display device is installed on a load such as a wall or a back cover, a gap exists between the display device and the load, affecting the aesthetics.

[0035] In the related art, the functional elements are externally arranged in an integrated box, and the display device and the integrated box are connected through a connecting line. The above method increases the production cost of the display device, and the connecting line between the integrated box and the display device is not convenient to store. When the display device is installed, the connecting line needs to be additionally fixed and stored, which increases the installation cost of the display device.

[0036] In view of the above problems, the embodiments of the present application provide a back plate, a backlight module and a display device, aiming to solve the problems of the gap between the display device and the load, the high production cost of the display device and the high installation cost of the display device.

[0037] In order to illustrate the technical solutions of the present application, the specific embodiments and drawings will be described below.

[0038] Please refer to Figures 1 to 4The first aspect of the present application provides a backboard 1 comprising a bottom plate 11 and a side plate 12.

[0039] The side plate 12 is arranged along the side edge of the bottom plate 11, and the side plate 12 comprises a first sub-plate 121, a second sub-plate 122 and a third sub-plate 123. The first sub-plate 121 and the second sub-plate 122 are both connected with the third sub-plate 123, and the first sub-plate 121 and the second sub-plate 122 are located on the same side of the third sub-plate 123 along a first direction (Z direction in the figure). The third sub-plate 123 is located on the side of the bottom plate 11 away from the first direction. The end of the first sub-plate 121 away from the third sub-plate 123 is connected with the bottom plate 11, and the end of the second sub-plate 122 away from the third sub-plate 123 protrudes from the bottom plate 11 along the first direction.

[0040] Since the end of the second sub-plate 122 away from the third sub-plate 123 protrudes from the bottom plate 11 along the first direction, the second sub-plate 122 and the bottom plate 11 can enclose a containing cavity for accommodating the optical film group 2 and the middle frame 3. At the same time, since the end of the first sub-plate 121 away from the third sub-plate 123 is connected with the bottom plate 11, the first sub-plate 121 and the bottom plate 11 can enclose another containing cavity for accommodating functional elements such as a connecting bracket, a system board, a circuit board and a sound box assembly. Without an external integrated box, the installation cost and production cost of the display device can be reduced, and the first sub-plate 121 and the second sub-plate 122 can shield the above-mentioned functional elements to shield the gap between the display device and the bearing object.

[0041] Please refer to Figure 3 The bottom plate 11 is a flat plate, and the bottom plate 11 comprises an upper surface 111 facing the first direction and a lower surface 112 away from the first direction. The upper surface 111 is used to support the optical film group 2.

[0042] The third sub-plate 123 is located on the side of the bottom plate 11 away from the first direction. The second sub-plate 122 extends from the third sub-plate 123 to the first direction until it protrudes from the upper surface 111 of the bottom plate 11. The second sub-plate 122 and the upper surface 111 of the bottom plate 11 enclose the above-mentioned containing cavity for accommodating the optical film group 2 and the middle frame 3. The first sub-plate 121 extends from the bottom plate 11 to the third sub-plate 123 until it protrudes from the lower surface 112 of the bottom plate 11. The first sub-plate 121 and the lower surface 112 of the bottom plate 11 enclose the above-mentioned containing cavity for accommodating the functional elements.

[0043] Please refer to Figure 3The upper surface of the bottom plate 11 is used for supporting the optical film group 2, the end of the second sub-plate 122 away from the third sub-plate 123 protrudes from the bottom plate 11 along the first direction, so that the surface of the second sub-plate 122 towards the bottom plate 11 can be attached to the middle frame 3 to fix and limit the position of the middle frame 3 and the optical film group 2, the first sub-plate 121 and the third sub-plate 123 are located between the second sub-plate 122 and the bottom plate 11, so that the width of the back plate 1 located on the side of the optical film group 2 is small under the premise that the size of the optical film group 2 is determined, so that the display device is more beautiful.

[0044] It should be noted that the number of side plates 12 can be set according to requirements.

[0045] For example, optionally, one side plate 12 is provided, and the side plate 12 is arranged along one edge of the bottom plate 11. In the display device assembled by using the back plate 1 of the embodiment, the side plate 12 can shield the gap between the display device and the carrier from one visual angle.

[0046] For example, optionally, two side plates 12 are provided, and the side plates 12 are arranged along two opposite edges of the bottom plate 11, or the side plates 12 are arranged along two adjacent edges of the bottom plate 11. In the display device assembled by using the back plate 1 of the embodiment, the side plates 12 can shield the gap between the display device and the carrier from two visual angles.

[0047] For example, optionally, three side plates 12 are provided, and the side plates 12 are arranged along three edges of the bottom plate 11. In the display device assembled by using the back plate 1 of the embodiment, the side plates 12 can shield the gap between the display device and the carrier from three visual angles.

[0048] When the display device is assembled by using the back plate 1 of the above-mentioned embodiments, the middle frame 3, the backlight 4 and the optical film group 2 can be arranged on the back plate 1 from the edge of the bottom plate 11 where the side plate 12 is not arranged.

[0049] Please refer to Figure 1 In the above-mentioned embodiments, the sealing plate 5 can also be arranged on the edge of the bottom plate 11 where the side plate 12 is not arranged, so that the sealing plate 5 cooperates with the back plate 1 of the above-mentioned embodiments to completely shield the gap between the display device and the carrier.

[0050] For example, optionally, four side plates 12 are provided, and the side plates 12 are arranged along four edges of the bottom plate 11. In the display device assembled by using the back plate 1 of the embodiment, the side plates 12 can completely shield the gap between the display device and the carrier.

[0051] In the above embodiment, the four side plates 12 and the bottom plate 11 enclose a containing cavity with an opening facing the first direction. When assembling the backlight assembly using the back plate 1 of the present embodiment, the middle frame 3, the backlight source 4 and the optical film set 2 can be arranged on the back plate 1 from the opening of the containing cavity. It should be noted that in the present embodiment, the side plate 12 is required to be free of a limiting structure (for example, the fourth sub-plate 124 in Figure 3 the bottom plate 11 facing the first direction, i.e., the side plate 12 is free of a limiting structure shielding the opening of the containing cavity.

[0052] It should be noted that in the direction opposite to the first direction, the height of the first sub-plate 121 is higher than the functional element to achieve the effect of shielding the functional element from the side.

[0053] In some embodiments, the first sub-plate 121 is perpendicularly connected with the bottom plate 11.

[0054] By adopting the above technical solution, the strength of the side plate 12 can be enhanced.

[0055] Alternatively, the first sub-plate 121 can also be connected with the bottom plate 11 at a certain angle. For example, the included angle between the first sub-plate 121 and the lower surface 112 of the bottom plate 11 is obtuse.

[0056] In some embodiments, the third sub-plate 123 extends 90 degrees from the first sub-plate 121 in the direction away from the bottom plate 11.

[0057] By adopting the above technical solution, the third sub-plate 123 is perpendicularly connected with the first sub-plate 121, which can enhance the overall strength of the side plate 12, and enable the third sub-plate 123 to be attached to the carrier, so that the third sub-plate 123 and the carrier can be seamlessly attached. Moreover, the first sub-plate 121 attached to the carrier can increase the contact area between the back plate 1 and the carrier.

[0058] Alternatively, the third sub-plate 123 can also be folded from the first sub-plate 121 at other angles in the direction away from the bottom plate 11. For example, 30 degrees, 45 degrees or 60 degrees.

[0059] In some embodiments, the second sub-plate 122 is arranged in parallel with the first sub-plate 121.

[0060] By adopting the above technical solution, the overall width and volume of the back plate 1 can be reduced, and the strength of the side plate 12 can be enhanced.

[0061] Please refer to Figure 4In some embodiments, the first sub-plate 121, the second sub-plate 122 and the third sub-plate 123 are formed by multiple times of folding the side plate 12. The first sub-plate 121 is connected perpendicularly to the bottom plate 11, and the first sub-plate 121 extends in a direction opposite to the first direction. The third sub-plate 123 is folded by 90 degrees from the first sub-plate 121 in a direction away from the bottom plate 11, and the second sub-plate 122 is folded by 90 degrees from the third sub-plate 123 in the first direction and protrudes from the bottom plate 11.

[0062] In some embodiments, the second sub-plate 122 and / or the third sub-plate 123 has a lifting slot 1231, and the lifting slot 1231 is recessed towards the bottom plate 11.

Thus, the back plate 1 can be conveniently carried and assembled with the optical film group 2, the middle frame 3 and the like. Moreover, by adopting the above technical solution, the strength of the side plate 12 can be enhanced, so that the side plate 12 is not easy to deform, thereby ensuring the perpendicularity of the back plate 1.

[0064] In some embodiments, the surface of the lifting slot 1231 on the second sub-plate 122 and / or the third sub-plate 123 towards the first direction is flush with at least part of the bottom plate 11.

[0065] By adopting the above technical solution, the lifting slot 1231 can support the optical film group 2 and the middle frame 3 arranged horizontally on the third sub-plate 123, so as to enhance the stability of the connection relationship between the optical film group 2 and the middle frame 3 and the back plate 1, and the optical film group 2 and the middle frame 3 can be effectively prevented from being broken.

[0066] Please refer to Figure 2 , Figure 5 and Figure 6 In some embodiments, the lifting slot 1231 is a stamping boss on the third sub-plate 123, and the stamping boss is arranged protruding in the first direction.

[0067] By adopting the above technical solution, the direction of the slot of the lifting slot 1231 is opposite to the first direction. When the display device is attached to the carrier, the direction of the slot of the lifting slot 1231 is towards the carrier, and the carrier can cover the slot of the lifting slot 1231, so that the display device is more beautiful after being attached to the carrier.

[0068] Moreover, by adopting the above technical solution, the stamping boss is located between the first sub-plate 121 and the second sub-plate 122, and the space between the first sub-plate 121 and the second sub-plate 122 is reasonably utilized, without additionally increasing the size and volume of the back plate 1.

[0069] In the above embodiment, the stamping protrusion protrudes in the first direction to be flush with at least part of the bottom plate 11. The surface of the hand-lifting groove 1231 facing the first direction being flush with at least part of the bottom plate 11 means that the groove bottom of the hand-lifting groove 1231 (also the mesa of the stamping protrusion facing the first direction) is flush with at least part of the bottom plate 11.

[0070] In some embodiments, multiple hand-lifting grooves 1231 (stamping protrusions) are provided and are distributed at intervals.

[0071] By adopting the above technical solution, not only the strength of the side plate 12 can be enhanced, but also the stability of the connection relationship between the back plate 1 and the optical film group 2 and the middle frame 3 can be enhanced.

[0072] Optionally, in some embodiments, the hand-lifting groove 1231 is a stamping protrusion on the second sub-plate 122, and the stamping protrusion is arranged to protrude towards the bottom plate 11.
