Abstract

Embodiments of the present disclosure provide a bracket structure, a sub-display panel module, and a tiled display device. The bracket structure includes a body and at least one transfer motion adjustor. The body has a support surface, an assembly surface, and at least one side surface including a first side surface. The transfer motion adjustor includes: a first rotation member and a first guide member. A first hole is provided on the first side surface, so that a first external jig adjusts the first rotation member to rotate through the end of the first rotation member close to the first side surface and exposed from the first hole. A second hole is provided on the assembly surface, and the first guide member is configured to move along the second hole to adjust a protruding amount of the first guide member on the assembly surface.

First claim
