Abstract:
A method for transferring a light-emitting diode (LED) and a light-emitting base plate are disclosed. The method for transferring an LED includes: providing a target base plate and a transfer base plate, wherein the target base plate includes a target substrate and a plurality of pad sets disposed on the target substrate, and the transfer base plate includes a transfer substrate and a blue film disposed on the transfer substrate, wherein a plurality of to-be-transferred LEDs are connected to the blue film; connecting the to-be-transferred LEDs to the pad sets in alignment; energizing the plurality of to-be-transferred LEDs to separate the blue film from the to-be-transferred LEDs; and removing the transfer base plate.
