Abstract
A transfer head for transferring micro element includes a cavity; a plurality of vacuum paths connected with the cavity respectively with valves configured at the connection between the cavity and the vacuum paths and used for opening/closing; a plurality of suction nozzles connected with the vacuum paths, wherein the suction nozzles hold or release the micro element via vacuum pressure; vacuum pressure is transmitted by each vacuum path; a switching component for controlling valve to open/close each vacuum path, so as to control the suction nozzles to hold or release required micro element via vacuum pressure. Further, the switching component includes a CMOS memory circuit and an address electrode array connected to the CMOS memory circuit to realize micro-switch array. The transfer head can selectively transfer a plurality of micro elements at one time.
