[0074] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be described in further detail below in conjunction with the drawings and specific embodiments.

[0075] The present disclosure will be described in further detail below with reference to the drawings. In each of the drawings, the same elements are denoted by similar reference numerals for the purpose of clarity. Furthermore, some well-known parts can not be shown in the drawings.

[0076] Many particular details of the present disclosure are described in the following, such as the structure, material, size, processing and technique of components, so as to make the present disclosure more clearly understood. But as the skilled in the art can understand, the present disclosure can be implemented without these particular details.

[0077] The terms "first", "second", and similar terms used in the embodiments of the present disclosure do not denote any order, number or importance, but are used to distinguish different components. Also, the terms "comprise", "comprising", and similar terms mean that the elements or objects before the term encompass the elements or objects listed after the term and their equivalents, and do not exclude other elements or objects. The terms "connected" or "linked" or similar terms between two structures mean not only direct contact between the two structures, but also indirect connection between the two structures through other structures.

[0078] In addition, the "fixed" between two structures in the present disclosure only represents that the two structures cannot be separated at a certain state or moment, but the two structures can also be separated at other states or moments. For example, when the screw is screwed into the corresponding screw hole, the screw and the screw hole form a fixed connection, but the screw can also be unscrewed from the screw hole, so that the screw and the screw hole form a separation.

[0079] The spliced display device includes a box body and a plurality of sub-display panel assemblies assembled on the box body, wherein the sub-display panel assembly includes a display substrate and a bracket structure, and the bracket structure has a support surface, and the distance between the support surface and the box body is the support height of the bracket structure.

[0080] In actual application, it is found that after the sub-display panel assembly is assembled on the box body, due to the assembly error and other factors in the assembly process, the support surface of the bracket structure in the currently assembled sub-display panel assembly may be inclined, the actual support height of the bracket structure may deviate from the pre-designed support height, and the like, so that the support surface of the bracket structure in the currently assembled sub-display panel assembly has a step difference with the support surface of the bracket structure in the sub-display panel assembly already assembled on the box body. At this time, the display surface of the display substrate in the currently assembled sub-display panel assembly is not in the same plane with the display surface of the display substrate in the sub-display panel assembly already assembled on the box body. When the spliced display device displays a picture, the area where the at least two sub-display panel assemblies with the step difference are located will have a concave-convex or split feeling, which greatly affects the overall picture display effect of the spliced display device.

[0081] In the related art, when adjusting the step difference between the support surfaces of the bracket structure, the entire sub-display panel assembly needs to be disassembled from the cabinet, and then the sub-display panel assembly is reassembled to the cabinet to adjust the position of the support surface of the bracket structure in the sub-display panel assembly, so as to eliminate the step difference between the support surface of the bracket structure in the currently assembled sub-display panel assembly and the support surface of the bracket structure in the sub-display panel assembly already assembled on the cabinet, and to realize step difference adjustment. However, the way of adjusting the step difference by reassembling in the related art will cause low assembly efficiency of the spliced display device. In addition, there are still inevitable factors of assembly error in the reassembly process, it is difficult to accurately adjust the step difference, and the phenomenon of reassembling the same sub-display panel assembly for multiple times may occur.

[0082] In the related art, an adjustment mechanism based on magnetic force or back top screw is also provided on the bracket structure to realize step difference adjustment, but it is limited to complex overall matching scheme, large actual site operation difficulty, and limitation on front and rear adjustment space, and sometimes affected by the back mounting bracket, which cannot be effectively adjusted.

[0083] Figure 1 A structural schematic diagram of the bracket structure provided by the embodiments of the present disclosure. Figure 2 A sectional schematic diagram of the transmission adjustment structure in the embodiments of the present disclosure. As shown in Figure 1 and Figure 2 The bracket structure includes a bracket body 1 and at least one transmission adjustment structure 5. The bracket body 1 includes a support part 2, an assembly part 4, and a connecting part 3. The support part 2 and the assembly part 4 are oppositely arranged in a first direction X. The connecting part 3 is located between the support part 2 and the assembly part 4 and connected to both the support part 2 and the assembly part 4. The connecting part 3 has a first side surface 3a. The transmission adjustment structure 5 is located between the support part 2 and the assembly part 4. The transmission adjustment structure 5 includes an adjustment piece 6, a transmission piece 7 connected to the adjustment piece 6, and a response piece 8 connected to the transmission piece 7. The adjustment piece 6 is located between the support part 2 and the assembly part 4 and close to the position of the first side surface 3a. At least part of the adjustment piece 6 is located on the side of the first side surface 3a away from the bracket body 1 for external adjustment. The adjustment piece 6 is configured to drive the transmission piece 7 to move in response to external adjustment. The assembly part 4 is provided with a second hole 9 penetrating the assembly part 4 in the first direction X at a position corresponding to the response piece 8. The response piece 8 is configured to move in the second hole 9 in the first direction X in response to the movement control of the transmission piece 7. Part of the response piece 8 can be stretched out from the surface of the assembly part 4 away from the support part 2 through the second hole 9.

[0084] In the embodiments of the present disclosure, the support portion 2 on the bracket body 1 is a portion on the bracket body 1 for supporting the display substrate, the side surface of the support portion 2 away from the assembly portion 4 is a support surface 2a, and the display substrate can be fixed on the support surface 2a; the assembly portion 4 on the bracket body 1 is a portion on the bracket body 1 for assembling with the box body, and the assembly portion 4 has an assembly surface 4a, which is a surface of the assembly portion 4 facing the box body and mutually assembled with the box body.

[0085] In some embodiments, the support portion 2 and the assembly portion 4 can be plate-shaped; in other embodiments, the support portion 2 can also be a frame-shaped structure with a hollowed-out area, and the circuit structure (such as COF, FPC, etc.) on the non-display surface of the display substrate can extend out through the hollowed-out area and be accommodated in the space surrounded by the support portion 2, the assembly portion 4, and the connecting portion 3.

[0086] In some embodiments, the support portion 2, the assembly portion 4, and the connecting portion 3 can be integrally formed. That is, the bracket body 1 is an integrally formed structure.

[0087] Optionally, the assembly of the assembly portion 4 and the box body can be achieved by cooperation of the positioning hole and the positioning column, magnetic attraction, suction cup fixing, etc., so as to achieve the assembly of the sub-display panel assembly and the box body. The present disclosure does not limit the fixing mode of the assembly portion 4 and the box body.

[0088] In the embodiments of the present disclosure, when the position of the support surface 2a of the bracket structure needs to be adjusted for step difference adjustment, at least one adjusting piece 6 can be adjusted to change the extension amount of at least one responding piece 8 extending out from the side surface (i.e., the assembly surface 4a above) of the assembly portion 4 away from the support portion 2. Since the support surface 2a and the assembly surface 4a remain relatively fixed, the distance between the assembly surface 4a and the surface of the box body at the corresponding position can be adjusted by changing the extension amount of the responding piece 8 extending out from the assembly surface 4a, so that the position of the support surface 2a of the bracket structure changes, thereby achieving step difference adjustment. The greater the extension amount of the responding piece 8 extending out from the assembly surface 4a, the greater the distance between the assembly surface 4a and the box body at the corresponding position; the smaller the extension amount of the responding piece 8 extending out from the assembly surface 4a, the smaller the distance between the assembly surface 4a and the box body at the corresponding position.

[0089] In the embodiments of the present disclosure, when the step difference problem occurs, the position of the bracket structure can be adjusted without disassembling the bracket structure from the box, so that the step difference between the support surfaces 2a of different bracket structures can be effectively adjusted. Compared with the related art, the step difference adjustment scheme in the present disclosure eliminates the process of "first disassembly and then reassembly", so that the technical scheme of the present disclosure can effectively improve the assembly efficiency of the spliced display device. At the same time, the technical scheme of the present disclosure can accurately control the extension amount of the response member 8 extending from the assembly surface 4a, that is, the position of the support surface 2a of the bracket structure can be accurately adjusted, so that the step difference can be accurately adjusted.

[0090] In addition, since the adjusting member 6 is located between the support part 2 and the assembly part 4 and close to the first side surface 3a, and at least part of the adjusting member 6 is located on the side of the first side surface 3a away from the bracket body 1, the adjusting member 6 can be adjusted from the first side surface 3a, so that during the adjustment of the position of the support surface 2a of the bracket structure, the front and rear installation environments of the sub-display panel assembly (the space on the side of the display substrate away from the bracket structure and the space on the side of the bracket structure away from the display substrate) are not required, so that the application ability is strong.

[0091] More importantly, due to the presence of the transmission member 7, the positions of the adjusting member 6 and the response member 8 can be different, and the response member 8 can be arranged in any area between the support part 2 and the assembly part 4, that is, the second hole 9 for the response member 8 to extend can be arranged at any position of the assembly surface 4a. That is, the assembler can adjust the distance between any position on the assembly surface 4a (only the response member 8 and the second hole 9 need to be arranged at the corresponding position) and the box from the first side surface 3a to adjust the position of the bracket structure. In the present disclosure, the components for the assembler to adjust are concentrated near the first side surface 3a, which is convenient for the assembler to operate.

[0092] In some embodiments, the connecting part 3 also has a second side surface 3b opposite to the first side surface 3a in the second direction Y, and the response member 8 is located between the support part 2 and the assembly part 4 and close to the second side surface 3b. That is, the assembler can control the extension amount of the response member 8 extending from the assembly surface 4a near the second side surface 3b through the adjusting member 6 near the first side surface 3a to adjust the distance between the area where the assembly surface 4a is located near the second side surface 3b and the surface of the box. Details will be described later in combination with specific examples.

[0093] In some embodiments, the adjusting member 6 comprises: a first rotating member 61 having a first rotating axis extending in parallel with the first direction X, the first rotating member 61 being configured to rotate about the first rotating axis in response to external adjustment and to drive the transmission member 7 to move; and the responding member 8 comprises: one or more second rotating members 81 connected with the transmission member 7, the second rotating member 81 having a second rotating axis extending in parallel with the first direction X, the second rotating member 81 being configured to rotate about the second rotating axis in response to the control of the movement of the transmission member 7 and to move along the second hole 9.

[0094] In some embodiments, the first rotating member 61 comprises: a first adjusting knob 601 and a first connecting knob 602 arranged along the first direction X, at least part of the first adjusting knob 601 being located on the side of the first side face 3a away from the bracket body 1 for external adjustment, the first adjusting knob 601 being configured to rotate about a first rotating axis (the first rotating axis being parallel to the first direction X and passing through the geometric center of the first rotating member 601) in response to external adjustment and to drive the first connecting knob 602 to synchronously rotate about the first rotating axis.

[0095] The second rotating member 81 comprises: a second connecting knob 801 and a second screw 802 arranged along the first direction X, the second screw 802 extending along the first direction X, and the second hole 9 being provided with an inner thread matching the outer thread of the second screw 802.

[0096] The transmission member 7 is connected with the first connecting knob 602 and the second connecting knob 801, and the transmission member 7 is configured to drive the second connecting knob 801 to rotate about the second rotating axis in response to the rotation of the first connecting knob 602 about the first rotating axis; the second screw 802 is connected with the second connecting knob 801 and can rotate about the second rotating axis with the second connecting knob 801 to move along the second hole 9. At this time, the second rotating axis is an axis passing through the geometric center of the second screw 802 and parallel to the extension direction of the second screw 802.

[0097] Referring to Figure 2 In some embodiments, the adjusting member 6 further comprises: a first connecting rod 603 corresponding to the first rotating member 61, the first connecting rod 603 extending along the first direction X; one end of the first connecting rod 603 being connected with the assembling part 4, and the first adjusting knob 601 and the first connecting knob 602 being sleeved outside the first connecting rod 603 so as to rotate about the first connecting rod 603. At this time, the first rotating axis is an axis passing through the geometric center of the first connecting rod 603 and parallel to the extension direction of the first connecting rod 603.

[0098] It should be noted that in the embodiments of this disclosure, the first connecting rod 603 and the assembly part 4 can be fixedly connected or non-fixedly connected (for example, the first connecting rod 603 and the assembly part 4 can be connected by screws, snaps, etc.). This disclosure does not limit this. Figure 2 The illustration only shows the first connecting rod 603 being inserted into a hole in the assembly part 4 to connect with the assembly part 4. This illustration is only for illustrative purposes and does not limit the technical solutions of this disclosure.

[0099] See Figure 2 As shown, the assembler can rotate the first adjusting wheel 601 to make the first connecting wheel 602 rotate synchronously around the first rotating axis. The rotation of the first adjusting wheel 601 drives the transmission component 7 to move. The movement of the transmission component 7 will drive the second connecting wheel 801 to rotate around the second rotating axis. At the same time, the second screw 802 follows the second connecting wheel 801 to rotate around the second rotating axis. The rotation of the second screw 802 will cause the second screw 802 to move along the second hole 9. The extension amount of the second screw 802 from the assembly surface 4a changes, and the distance between the assembly surface 4a and the housing at the corresponding position can change.

[0100] Figure 3A This is another cross-sectional schematic diagram of the transmission adjustment structure in an embodiment of this disclosure. Figure 3B This is another cross-sectional schematic diagram of the transmission adjustment structure in an embodiment of this disclosure. For example...

[0112] Referring to Figure 6A In some embodiments, the third adjustment knob 604 is sleeved outside the first connecting rod 603 and fixed with the first connecting rod 603. Referring to Figure 6BAs shown, in some embodiments, the third adjusting wheel 604 is fixed to the end of the first connecting rod 603 away from the assembly part 4. In this embodiment, it is only necessary to ensure that the third adjusting wheel 604 is fixed to the first connecting rod 603 (including the first screw 603a) so as to drive the first connecting rod 603 to rotate around the first rotation axis; during the rotation of the first connecting rod 603 around the first rotation axis, the rotation of the first connecting rod 603 will not drive the first rotating member 61 sleeved on the first connecting rod 603 to rotate.
