Abstract
A transfer head, a transfer head array, and a method for transferring an inorganic light-emitting diode are provided. The transfer head for transferring an inorganic light-emitting diode includes a first groove and a second groove. The first groove and the second groove are arranged sequentially in a first direction, and are connected to each other. The first groove is configured to provide an inlet and an outlet for the inorganic light-emitting diode to enter and exit the transfer head. After the inorganic light-emitting diode enters the second groove through the first groove, at least a partial structure of the inorganic light-emitting diode is confined in the second groove. Picking up and transferring the inorganic light-emitting diode is realized by the transfer head with a simple structure.
