Abstract
The disclosure provides an apparatus for transferring LED chips, including: first light source configured to generate and emit first light rays; first support structure configured to carry load substrate, load substrate including light-transmissive substrate and the LED chips fixed on side of the light-transmissive substrate away from first light source by dissociation adhesive; second support structure configured to carry to-be-transferred substrate on side of the LED chips away from light-transmissive substrate; and optical control mechanism on side of light-transmissive substrate away from the LED chips and configured to control propagation direction of first light rays that irradiate onto first radiation region of the optical control mechanism to form target light rays that irradiate onto target radiation region of load substrate, so that dissociation adhesive in target radiation region is dissociated to transfer LED chips in target radiation region to to-be-transferred substrate.
