Abstract
The present disclosure provides a micro light emitting diode transfer device and a micro light emitting diode transfer method. The micro light emitting diode transfer device includes a holding member, a light source, and a liquid crystals light valve. The liquid crystals light valve is disposed on a transmission path of planar light and includes a plurality of sub light valves. The micro light emitting diodes of irradiated part can be separated from the transfer substrate and adhere to a target substrate, and thereby the micro light emitting diodes can be selectively transferred.
