摘要： Provided are a mass transfer device and a mass transfer method. The mass transfer device is provided with multiple channels, a first opening of each channel is arranged on a first surface of the mass transfer device, a second opening of each channel is arranged on a second surface of the mass transfer device, and the distances between the channels are gradually increased along a direction from the first surface to the second surface. In the provided mass transfer method, through a laser irradiation mode, the Micro-LEDs are separated from the first substrate and enter the channels of the mass transfer device through the first openings, and falling into Micro-LED to-be-installed positions on a second substrate through the second openings of the channels, thereby transferring the Micro-LEDs from the first substrate to the second substrate.
