MICRO LIGHT EMITTING DIODE TRANSFER DEVICE AND MICRO LIGHT EMITTING DIODE TRANSFER METHOD

摘要

A micro light emitting diode transfer device (100) and a micro light emitting diode (22) transfer method. The micro light emitting diode transfer device (100) comprises a holding member (11), a light source (12), and a liquid crystal light valve (13). The liquid crystal light valve (13) is disposed on a transmission path of planar light and comprises a plurality of sub light valves (134). By controlling the opening and closing of the sub light valves (134), irradiated micro light emitting diodes (22) are detached from a transfer substrate (20) and adhered to a target substrate (30), so as to achieve the technical effect of selectively transferring the micro light emitting diodes (22).
