The embodiments of the application provide a tiling component and a tiled display screen. A connector on a tiling panel is positioned by a positioning portion, so that the connector is aligned. Then, a fixation is achieved by fixing a mortise and tenon structure. As a result, multiple tiling panels are efficiently and seamlessly tiled through the connectors. The tiling component provided in the embodiments of the application improves the installation efficiency of the tiled display screen and simplifies the installation means. Moreover, it is possible to guarantee the seamless design between display units.
