Problems solved by technology

[0004]Different micro-LEDs come from different growth substrates. The transfer process of micro-LEDs from front to back is growth substrate, temporary substrate, transfer substrate and display backplane, It is conceivable that the completion of a huge transfer of a display backplane requires repeated operations, which is extremely inefficient

Abstract

The invention provides a mass transfer device and a mass transfer method. The mass transfer device comprises a main body, a plurality of telescopic parts, a plurality of transfer substrates and a processor. The fixed end of each telescopic part is arranged on the main body; each transfer substrate is fixedly arranged at the movable end of the corresponding telescopic part; and the processor is electrically connected with each telescopic part, and the processor controls the operation of the telescopic parts so as to transfer micro light-emitting diodes from the transfer substrates to a display backboard. According to the mass transfer device and mass transfer method provided by the technical schemes of the invention, different types of micro light-emitting diodes are respectively arranged on the plurality of transfer substrates, and the plurality of transfer substrates are respectively driven by the plurality of telescopic parts, so that the micro light-emitting diodes are transferred to the display backboard; and in a certain pixel region, transfer of one kind of micro light-emitting diodes can be completed at a time, repeated operation is avoided, and mass transfer efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of LEDs, relates to a mass transfer device, and also relates to a mass transfer method based on the mass transfer device. Background technique [0002] Micro light emitting diode (Micro Light Emitting Diode, Micro-LED), has better photoelectric efficiency, brightness and contrast ratio and lower power consumption than general LED. In order to realize the display function, it is necessary to load a plurality of micro light emitting diodes on the display backplane to form a pixel area, and realize the display function through the micro light emitting diode array in the pixel area. [0003] As we all know, the optical three primary colors include red, green and blue. After the optical three primary colors are mixed, all the colors required for display can be formed. In order to realize the full-color display function, red miniature light-emitting diodes, green miniature light-emitting diodes, and blue miniatur...
