Abstract
The disclosure provides a micro light-emitting diode mass transfer apparatus and method. The micro light-emitting diode mass transfer apparatus includes a solution container, display backplanes, a solution drive assembly and a liquid level control assembly. The solution container contains a transfer solution, and micro light-emitting diodes to be transferred float on the liquid surface of the transfer solution. The display backplanes are submerged in the transfer solution and each provided with a plurality of chip mounting cells; mounting cell opening directions of the plurality of chip mounting cells face toward the micro light-emitting diodes; and at least one of the chip mounting cells is exposed on the liquid surface. The solution drive assembly is disposed in the solution container. The liquid level control assembly is configured to control a liquid level of the transfer solution in the solution container. The liquid level control assembly controls the liquid level of the transfer solution, the solution drive assembly provides a centrifugal force to the transfer solution, and the micro light-emitting diodes are precisely transferred into the corresponding chip mounting cells through the centrifugal force.
