Abstract: The present disclosure provides a sub-display panel assembly, including: a display substrate; a frame, including: a bottom plate having a support surface and a mounting surface arranged opposite to each other, where the support surface is configured to bear the display substrate; and a first circuit board on a side of the bottom plate away from of display substrate, including: a first circuit board body connected to the mounting surface of the bottom plate through an elastic component, where the elastic component is configured to support the first circuit board body and enable the first circuit board body to move relative to the bottom plate. An embodiment of the present disclosure further provides a tiled display apparatus.

Abstract: The present disclosure provides a bracket structure. The bracket structure includes a bracket body and at least one transmission adjustment structure, wherein the bracket body includes a supporting portion, an assembly portion and a connecting portion, wherein the supporting portion and the assembly portion are disposed opposite in a first direction, the connecting portion is located between the supporting portion and the assembly portion and the connecting portion has a first side surface; the transmission adjustment structure is located between the supporting portion and the assembly portion, and includes an adjustment member, a transmission member connected with the adjustment member and a response member connected with the transmission member; the adjustment member is located between the supporting portion and the assembly portion and close to the first side surface.

Abstract: The present disclosure provides a bearing box and a splicing display apparatus. The bearing box includes: a box body configured to bear a display assembly, where a fixing part is disposed on a side of the display assembly facing the box; an adjusting member on the box body, including: a magnetic part and an adjusting part connected to the magnetic part, where the magnetic part is configured to be connected to the fixing part, and the adjusting part is configured to be movable under an operation of the magnetic operating member along a thickness direction of the display assembly relative to the box body, to adjust a distance between the fixing part and the box body.

Abstract: A transmission adjustment structure includes: a shell, a rotation part, a transmission part, and a response part. An adjustment hole exposing one end of the rotation part is provided at a position on the shell corresponding to the rotation part, the other end of the rotation part is connected to the transmission part; a guide hole exposing one end of the response part is provided at a position on the shell corresponding to the response part, the other end of the response part is in contact with the transmission part; the rotation part is rotatable in response to controlling by an external tool on the end of the rotation part exposed by the adjustment hole; the transmission part is movable along a first direction in response to rotation controlling of the rotation part, the first direction is an extension direction of the transmission part.

Abstract: The present disclosure provides a bearing case, including: a case body configured to bear a plurality of sub-display panel components; and at least one seam adjustment structure component, and each seam adjustment structure component corresponds to two adjacent sub-display panel components, is connected to the case body, and is configured to adjust a width of a splicing seam between the corresponding two adjacent sub-display panel components. Embodiments of the present disclosure further provide a splicing display device.
