Abstract
A mass transfer device includes at least one transfer cavity. Each transfer cavity is configured to accommodate a plurality of micro light-emitting diodes. Each transfer cavity includes a bottom plate and a cavity wall connecting the bottom plate. The bottom plate defines a plurality of through holes spaced apart from each other. The transfer cavity is used to transfer the plurality of micro light-emitting diodes to the array substrate of a display panel through the plurality of through holes.
