In this embodiment, referring to fig. 2, two second hanging pieces 3 are arranged on the backboard main body 1, and the two second hanging pieces 3 are respectively located at two side angle positions of the backboard main body 1 near the sky side; by suspending the back plate body 1 at both angular positions of the sky side, the whole is more stable. Corresponding to the number of the second hitching members 3, there are also two first hitching members 2. In addition, in the present embodiment, two adjusting members 4 are also provided, and the two adjusting members 4 are respectively located at two side angle positions on the ground side of the backboard body 1. The two adjusting pieces 4 are supported at two side angle positions of the back plate main body 1 close to the ground side, so that the stability of the back plate main body 1 after being hung is further improved.

It should be noted that, according to the shape and specification of the display device to which the display device is applied, the number and the arrangement positions of the first hanging piece, the second hanging piece and the adjusting piece can be flexibly selected. Wherein, because of the mutually matched relationship, the number of the first hanging pieces and the second hanging pieces is generally the same. The number of the adjusting pieces can be different from that of the second hanging pieces; for example, a second hanging member is provided at each of two side angle positions of the back plate body near the sky side, and an adjusting member is provided only at the midpoint of one side of the back plate body near the ground side.

Based on the above embodiments, referring to fig. 2 to 8, the usage process of the backplane assembly is as follows: the display device is assembled using the back plate body 1. And selecting a hanging position on the wall body 001, and fixing the first hanging part 2 at the hanging position of the wall body 001. And fixing the second hanging piece 3 on the backboard main body 1, and arranging the adjusting piece 4 on the backboard main body 1 in a threaded connection manner. The display device is suspended at a suspension position by a hanger 2 and a second hanger 3, and the ground side of the display device is supported by an adjusting member 4. The adjusting piece 4 is rotated to adjust the extending length of the adjusting piece, the distance between the ground side of the display device and the wall body 001 is adjusted, the display device is kept in a parallel state with the wall body 001, therefore, the display device is prevented from being inclined relatively to the wall body greatly and causing adverse effects on the display effect, and the display effect is ensured. The final suspension state is shown with reference to figure 8.

It should be noted that the state in which the display device is parallel to the wall 001 is only an optional suspended state. According to different hanging requirements or display requirements, the distance between the ground side of the display device and the wall body can be changed by changing the extending length of the adjusting piece 4, so that the display device is in a state of being inclined relative to the wall body.

As an alternative embodiment, with reference to fig. 6, the cap 402 of the adjustment member 4 is cylindrical in shape. Correspondingly, the mouth of the adjusting threaded hole 101 on the backplate body 1 further comprises a circular groove for accommodating the cap 402. By providing the circular groove, the threaded rod 401 can be screwed into the adjusting threaded hole 101, and the cap 402 can be completely accommodated in the circular groove, i.e., the adjusting member 4 does not protrude from the surface of the backplate main body 1 as a whole. Thus, when the ground side of the backboard main body 1 is not required to be supported, the space on the surface of the backboard main body 1 can be effectively saved, and the protruding adjusting piece 4 can be prevented from colliding with other components.

Further, the diameter of the circular groove is larger than the diameter of the cap 402. When the adjusting member 4 needs to be unscrewed to protrude out of the surface of the backplate main body 1, the gap between the circular groove and the cap 402 may allow room for operation, facilitating the unscrewing action of the adjusting member 4.

Further, the surface of the cap 402, which is used for contacting with the wall, is provided with a buffer material layer. By the arrangement of the buffer material layer, rigid contact can be changed into flexible contact when the cap 402 is in contact with the wall, so that the cap 402 is prevented from damaging the surface of the wall. Wherein, the material of the buffer material layer can be flexibly selected according to implementation requirements, such as rubber, acrylic, non-woven fabric and the like.

As an alternative embodiment, the first hanging piece comprises a hook which is also detachably provided with at least one washer. Through the setting of packing ring for articulate the groove and hang the back on the couple, the packing ring can be in and articulate between groove and the couple, thereby realizes finely tuning backplate main part and the relative position of first piece of articulate. For example, when the position of the first hanging piece on the wall body is not horizontal, the level of the backboard main body can be adjusted by arranging a gasket on the hook of any first hanging piece.

Based on the same inventive concept, the embodiment of the present invention further provides a display device, which includes the backplane assembly according to any of the above embodiments.

Because the display device of this embodiment has included the backplate subassembly of above-mentioned embodiment, this makes the display device of this embodiment when hanging the use, can further adjust the interval of backplate main part ground side and wall body through the regulating part on the basis that realizes firm suspension through first hitching member, second hitching member, regulating part to improve the tilt state of backplate main part, in order to guarantee the display effect.

Based on the same inventive concept, the embodiment of the utility model provides a concatenation screen is still provided, it includes: a plurality of display devices as described in the above embodiments are arranged in an array.

The tiled screen in the related art is formed by tiling a plurality of display devices in an array arrangement manner. When the spliced screen is hung for use, the ground side of the display devices is lack of support, so that the display devices are not positioned in the same plane, and a large acting force is generated at the splicing position between the display devices, so that the display effect and the service life of the spliced screen are influenced.

In this embodiment, the spliced screen is composed of the display devices as described in the above embodiments, and for each display device in the spliced screen of this embodiment, the ground side of the display device can be supported by the adjusting member thereon, and the distance between the ground side and the wall body can be adjusted, so that each display device in the spliced screen of this embodiment can be in the same plane by adjusting the adjusting member, the display effect is ensured, and the service life of the spliced screen of this embodiment can be effectively ensured.
