Abstract:
A micro LED transfer head is proposed. The micro LED transfer head includes: a holding member including a holding region that holds a micro LED by means of vacuum holding force and a non-holding region that does not hold the micro LED; and a porous member provided on top of the holding member and having arbitrary pores, wherein the holding region includes: a first holding region; and a second holding region provided above the first holding region, formed to have a larger opening area than the first holding region, and communicating with the first holding region and the porous member, whereby the micro LED transfer head selectively transfers the micro LED.
