Abstract: The present disclosure relates to an apparatus for transferring a light emitting diode (LED). The apparatus for transferring an LED includes: a pick-up unit configured to pick up at least some of multiple light emitting diodes (LEDs) arranged on one substrate, and, according to a received control signal, put down LEDs selected from among the picked-up LEDs on another substrate; and a controller configured to transmit the control signal to the pick-up unit so as to enable the pick-up unit to individually pick up or put down each of the multiple LEDs.
