Abstract
A micro LED transferring method is provided. The transferring method includes selectively applying a color conversion material to a mono-color substrate, the mono-color substrate including first micro LEDs in a first color; obtaining a multi-color substrate based on a result of the applying, the multi-color substrate including the first micro LEDs in the first color and second micro LEDs in a second color different from the first color; and irradiating a laser beam toward the multi-color substrate to transfer the first micro LEDs and the second micro LEDs to a target substrate.
