Abstract
Herein disclosed are a micro-component transfer head, a micro-component transfer device, and a micro-component display. Said micro-component transfer head comprises a carrying surface that corresponds to a micro-component extraction area. Said extraction area conforms with a first geometric object, which comprises at least an acute angle. A second geometric object comprises at least a right angle and is constituted of n copies of the first geometric object, n being an integer greater than 1. The shape of the first geometric object differs from that of the second.
