Abstract
A micro light emitting diode (LED) transfer device includes a transfer part configured to transfer a relay substrate having at least one micro LED; a mask having openings corresponding to a position of the at least one micro LED; a first laser configured to irradiate a first laser light having a first wavelength to the mask; a second laser configured to irradiate a second laser light having a second wavelength different from the first wavelength to the mask; and a processor configured to: control the at least one micro LED to contact a coupling layer of a target substrate, and based on the coupling layer contacting the at least one micro LED, control the first laser to irradiate the first laser light toward the at least one micro LED, and subsequently control the second laser to irradiate the second laser light toward the at least one micro LED.
