1. A bearing case, comprising:
a case body configured to bear a plurality of sub-display panel components; and
at least one seam adjustment structure component each corresponding to two adjacent sub-display panel components, wherein each seam adjustment structure component 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;
wherein each of the plurality of sub-display panel components comprises: a display substrate and a fixing frame, and the display substrate is fixed on a side of the fixing frame; wherein the case body comprises a bottom plate opposite to the plurality of sub-display panel components;
wherein the seam adjustment structure component comprises: an ejector rod comprising: a rod body and an insertion portion, the rod body penetrates through the bottom plate, and the insertion portion is fixed at an end of the rod body close to the sub-display panel components;
a cross-sectional area of a cross section of the insertion portion parallel to the bottom plate gradually increases along a direction approaching the rod body; and
part of an outer sidewall of the insertion portion is configured to be in contact with the outer sidewalls of the fixing frames in the corresponding two adjacent sub-display panel components.
